There is considerable uncertainty surrounding the future availability of hardwood timber from state-owned native forests in southern Queensland. The timber industry is becoming increasingly reliant on private native forests, where much is on properties primarily managed for beef cattle grazing. Historically, these forests have been periodically high-grade harvested without silvicultural treatment or cleared to increase pasture production where landholders have the right to do so. This study compares these traditional forest management practices at four case study properties against silvopastoral system alternatives. Merchantable timber, pasture and cattle production was estimated for each management scenario with a native forest silvicultural treatment response model. The net present value of each scenario was estimated over a 20-year management period. For all case study properties, the worst-performing forest management scenario was to clear forest for grazing. Investment in silvopastoral systems in southern Queensland was found to be financially attractive, particularly when silvicultural treatments were implemented in year zero to increase timber production. Silvicultural treatments increased the mean annual increment of merchantable timber over 20 years by an average of 1.3 m3/ha/year relative to the scenario where no management was performed in year zero. Forest management scenarios with silvicultural treatments had better financial performance than scenarios without silvicultural treatment. However, long payback periods and sovereign risk are serious impediments to silvopastoral system adoption in southern Queensland. If these concerns can be overcome, private native forests have the potential to be sustainably managed to improve the financial performance of farms, improve regional employment and income generation, supply Queensland’s future hardwood timber needs, and increase carbon sequestration and biodiversity conservation on private land.

Queensland, Australia's second largest state, has 4 million hectares of publicly owned state forest, managed for multiple use. The government and the community expect state forest management to protect biodiversity, landscapes, cultural heritage values and water quality. State forests are also available for a wide range of commercial and non-commercial uses including timber harvesting, honey production, eco-tourism,grazing, mining, quarrying, education, scientific research, military training and recreation. A proportion of this estate is located throughout Queensland's coastal zone, in close proximity to the major population centres. In the coastal mountains in particular, the juxtaposition of high conservation values, commercial timber, recreation and eco-tourism demands precipitates conflict over forest use and presents a challenge for multiple use planning systems. Beginning in 1986, state forest planning utilised a system called Management Priority Area Zoning (MPAZ). This was a manual system which partitioned forestry land into primary priority use zones with a variety of secondary uses permitted. Decisions were made by professional foresters without public input. Although many of the concepts in MPAZ are still valid,such an autocratic approach is no longer acceptable. In 1998, development began on a new forest planning system known as MUMPS (Multiple Use Management Planning System). It is broadly based on MPAZ, but incorporates GIS and decision-support technology coupled with the capacity for structured community participation. MUMPS is designed to operate on a scale of 50 000 to 100 000 ha, with the planning area subdivided into 100 to 150 planning units. At its analytical core, MUMPS is a phased process for forming a steering committee: collation of site-specific data, assessment and evaluation of a number of forest uses, procedures for gauging and incorporating community and stakeholder values and a process for examining management and compatibility as well as the preparation of a draft and final plan. To ensure its effectiveness, MUMPS is being developed in an iterative manner with field trials based on MUMPS modules and concepts, while the whole system is being integrated and refined. The Koombooloomba Ecotourism Project is one of these MUMPS trials. The site of the trial is a tropical, mountainous region in northern Queensland, partly in the Wet Tropics World Heritage Area. It includes an hydro-electric dam within publicly owned native forest and encompasses a number of key values including the world heritage rainforest, conservation,hydro-power generation, indigenous culture, timber,eco-tourism and recreation. In this case, MUMPS took over a stalled, unstructured planning process. The MUMPS process reinvigorated the earlier planning project, broadened the assessed values and resulted in a management plan. The case study demonstrates how forest managers, the community (including traditional Aboriginal land-owners),commercial tourism, recreationists and the hydro-electricity industry can cooperate in the sustainable management of a listed World Heritage mountain forest area. Issues associated with the methodology, community involvement and management implications are discussed and analysed.

Land management agencies in Queensland conduct planned burning for a variety of reasons, principally for management of fuels for human asset protection and biodiversity management. Using Queensland Parks and Wildlife Service’s archived manually derived fire reports, this study considered the individual components of the fire regime (extent, frequency and season) to determine variation between planned and unplanned fire regimes in south-east Queensland. Overall, between 2004 and 2015, planned fire accounted for 31.6% and unplanned fire 68.4% of all fire on Queensland Parks and Wildlife Service state-managed land. Unplanned fire was more common in spring (September–October), and planned fire was more common in winter (June–August). Unplanned fire affected 71.4% of open forests and woodlands (148563ha), whereas 58.8% of melaleuca communities (8016ha) and 66.6% of plantations (2442ha) were burnt with planned fire. Mapping fire history at a regional scale can be readily done with existing publicly available datasets, which can be used to inform the assessment of planned burning effectiveness for human asset protection and the management of biodiversity. Fire management will benefit from the continued recording of accurate fire occurrence data, which allows for detailed fire regime mapping and subsequent adaptive management of fire regimes in the public domain.

There is a prevailing paradigm that woody vegetation is expanding at the expense of grassland with reduced burning under pastoralism in the Mulga Lands biogeographic region in eastern Australia. This raises the possibility that the region is acting as a carbon sink. Vegetation boundaries were precisely positioned from rail survey plans dating from 1895 to 1900. This baseline was compared with the position of boundaries on 1952 aerial photography and 2010 Google Earth imagery. The conversion of forest to non-forest by mechanical clearing was also mapped from satellite imagery. There was no consistent trend in the direction of boundary movement for mulga (Acacia aneura F.Muell. ex Benth.), gidgee (Acacia cambagei R.T. Baker) forest or miscellaneous other forest types. The stability of the boundaries, despite the transition from aboriginal management to rangeland pastoralism, contrasts with dramatic declines in tree cover resulting from mechanical clearing. Mapping of forest cover from satellite imagery reveals that conversion of forest to non-forest has reduced mulga forest to 74%, gidgee forest to 30% and miscellaneous forest types to 82% of their original area. Annual clearing rates for the period between 1997 and 2005 were 0.83, 0.95 and 0.43% for those forest types, respectively. Clearing has declined substantially in the period 2005–09 since the advent of recent regulations in Queensland. The area remains a source of carbon emissions but this situation may reverse if restoration of mulga dry forest becomes an attractive land use with an emerging carbon market.

Concern about the risk of harmful human-induced climate change has resulted in international efforts to reduce greenhouse gas emissions to the atmosphere. We review the international and national context for consideration of greenhouse abatement in native vegetation management and discuss potential options in Queensland. Queensland has large areas of productive or potentially productive land with native woody vegetation cover with approximately 76 million ha with woody cover remaining in 1991. High rates of tree clearing, predominantly to increase pasture productivity, continued throughout the 1990s with an average 345,000 ha/a estimated to have been cleared, including non-remnant (woody regrowth) as well as remnant vegetation. Estimates of greenhouse gas emissions associated with land clearing currently have a high uncertainty but clearing was reported to contribute a significant proportion of Australia's total greenhouse gas emissions from 1990 (21%) to 1999 (13%). In Queensland, greenhouse emissions from land clearing were estimated to have been 54.5 Mt CO2-e in 1999. Management of native vegetation for timber harvesting and the proliferation of woody vegetation (vegetation thickening) in the grazed woodlands also represent large carbon fluxes. Forestry (plantations and native forests) in Queensland was reported to be a 4.4 Mt CO2-e sink in 1999 but there are a lack of comprehensive data on timber harvesting in private hardwood forests. Vegetation thickening is reported for large areas of the c. 60 million ha grazed woodlands in Queensland. The magnitude of the carbon sink in 27 million ha grazed eucalypt woodlands has been estimated to be 66 Mt CO2-e/a but this sink is not currently included in Australia's inventory of anthropogenic greenhouse emissions. Improved understanding of the function and dynamics of natural and managed ecosystems is required to support management of native vegetation to preserve and enhance carbon stocks for greenhouse benefits while meeting objectives of sustainable and productive management and biodiversity protection.

The effects on terrestrial fauna of clearing, fragmentation and regeneration of eucalypt forest and woodland were investigated in a former cattle-grazing area of south-east Queensland. The abundance of species and higher taxa was compared among four major habitat types: interior of relatively mature forest, interior of earlier stages of regenerating forest, cleared pasture, and abrupt edges between the forest and cleared land. The regenerating sites were several decades old and consisted mainly of Eucalyptus saplings 3–6 m high, with a grassy understorey. Numbers of pitfall-trapped invertebrate orders were significantly higher in forest interior and forest edge than in cleared or regenerating sites; numbers of coleopterans were significantly higher in forest interior sites than in cleared or regenerating sites; and numbers of isopterans were significantly higher in both forest interior and forest edge sites than in cleared sites. Total abundance of native non-flying mammals was significantly higher in forest interior than elsewhere. Other vertebrates apart from birds were detected in numbers too low for analysis. Cleared sites supported significantly lower numbers of avian species and Orders, and of total birds, than any other habitat in winter, with a similar but non-significant trend in summer. Forest interior sites showed a significantly higher abundance of several avian species than any other habitat, but noisy miners and Torresian crows were significantly more abundant in edge sites than in forest interior sites. Sites of low regeneration were chiefly utilised by birds characteristic of forest edge. Many decades of regeneration would appear to be necessary before many forest-dependant species are adequately supported in these areas.

Soil and land-management interactions in Australian native-forest regrowth remain a major source of uncertainty in the context of the global carbon economy. We sampled soil total organic C (TOC) and soil total N (TN) stocks at 45 sites within the Brigalow ecological community of the Brigalow Belt bioregion, Queensland, Australia. The sites were matched as triplets representing three land uses, specifically: uncleared native brigalow forest (‘Remnant’); grassland pasture (‘Pasture’), derived by clearing native vegetation and maintained as pasture for a minimum of 10 years, and; regrowing native brigalow forest (‘Regrowth’, stand ages ranging from 10 to 58 years) that had developed spontaneously after past vegetation clearing for pasture establishment. Soil TOC fractions and natural abundance of soil C and N isotopes were examined to obtain insight into C and N dynamics. An updated above- and belowground carbon budget for the bioregions was generated. Average soil TOC stocks at 0–0.3-m depth ranged from 19 to 79 Mg ha–1 and soil TN stocks from 1.8 to 7.1 Mg ha–1 (2.5th and 97.5th percentiles, respectively). A trend in stocks was apparent with land use: Remnant > Regrowth ≅ Pasture sites. Soil δ13C ranged from –14 to –27‰, and soil δ15N ranged from 4‰ to 17‰, in general reflecting the difference between Pasture (C4-dominated) land use and N2-fixing (C3-dominated) Remnant and Regrowth. Mid-infrared spectroscopy predicted C fractions as a percentage of soil TOC stock, which ranged from 5% to 60% (particulate), 20–80% (humus) and 9–30% (resistant/inert). The geo-referenced soil and management information we collected is important for the calibration of C models, for the estimation of national C accounts, and to inform policy developments in relation to land-resource management undertaken within the Brigalow Belt bioregions of Australia.

The Proserpine Rock-wallaby (Petrogale persephone) was not discovered until 1976, with scientific description occurring in 1982 by G.M. Maynes. Petrogale persephone occurs only within the Whitsunday Shire and on Gloucester Island, North Queensland and lives amongst rocky outcrops in elevated pockets of semi-deciduous vine forests. Food is found within the forest and in adjoining woodlands. Changes in land use and habitat fragmentation, through clearing, has isolated many colonies. Habitat loss remains as the single biggest threat to this species followed by road kills in specific areas. Other threats include predation, harassment and transfer of disease from feral and domestic animals. A Recovery Plan has been prepared which identifies priorities for research and management. These priorities include distribution surveys and mapping of habitat, habitat utilisation by P. persephone, captive colony establishment to study reproduction and age estimation and identifying the significance of road kills and predation on the population dynamics of this rock-wallaby. A public education and awareness program has also been developed for implementation.

Colonizer and colonized, we all inhabit these death-scarred landscapes. We are here by hope, and we are here by violence.Deborah Bird Rase (1999)The bunya pine has a special meaning for Queenslanders, being endemic to the Bunya Mountains and Blackall Ranges in the South-East corner of the state, with a small stand in North Queensland. The bunya holds particular significance for local Indigenous peoples. They are bound to the tree through custodial rights and obligations and systems of traditional environmental knowledge that incorporate ‘classification …empirical observations of the local environment… [and] self-management that governs resource use’, built up through generations of interaction with the bunya forests. Indigenous groups celebrated their spiritual links to the bunya pine in large seasonal gatherings where they feasted on its edible nuts and performed ceremonies, adjudicated disputes and traded goods. The bunya's majestic height, striking unique silhouette, dark green foliage, unique botanical features and Indigenous associations held a fascination for colonial artists, natural scientists, entrepreneurs and gardeners. Over the years they assumed custodianship of the bunya pine, assimilating it into Western scientific, economic, legal, horticultural, environmental and symbolic systems, which replaced Indigenous custodial rights, obligations and knowledge. The spectacular bunya gatherings were mythologised in colonial writings as mystical, primeval ceremonies and barbaric rituals. Despite ‘fierce and actively hostile tribal resistance’ to colonisation of their lands, Indigenous groups were progressively driven out of the bunya forests. Empty landscapes left by the retreating forests – victims of timber felling and land clearing – came to symbolise the vanishing ceremonies and dwindling Aboriginal populations of South-East Queensland. While surviving Indigenous groups were swept into centralised reserves and settlements from the late nineteenth century, so too the bunya trees were cordoned off in 1908, for their own protection, in Queensland's second national park at the Bunya Mountains, where they stood ‘like the spirits of the departed original Queenslanders, mourning over the days which are forever gone’.

Diurnal and nocturnal habitat use was determined from walk transect counts in a 40 000 ha study area in SE Queensland containing 3 land systems: (a) alluvial flats mainly clear of natural vegetation; (b) hills extending from the alluvial flats with open forest; and (c) plateaux with grassy and shrubby open forest. Habitat utilization was examined in relation to 3 vegetation variables (shrub density, live tree density and dead tree density) and 3 topographic variables (altitude, aspect and slope). Utilization was most consistent between day and night for live tree density and slope, being biased toward areas of moderate live tree density and against flat areas at both times. A preference for areas with moderate shrub density was more pronounced during the day than at night. Areas with moderate dead tree density were strongly preferred over areas with low dead tree density during the day, but at night there was no strong bias for or against areas with dead trees. M. parryi avoided very low altitudes at all times. Utilization of higher areas varied day and night, a diurnal preference for higher altitudes being ameliorated by some apparent downhill movement to lower slopes at night. A preference during the day for north and west aspects was not evident at night.

Many threatened species occur as small, isolated populations. Understanding the extent and genetic distinctiveness of these populations is essential for management. Nangura spinosa is a critically endangered skink known from two small populations in dry rainforest in south-east Queensland. We conducted targeted surveys between 2001 and 2010 at the two known N. spinosa sites (Nangur National Park, Oakview National Park area) and in 22 nearby forest blocks with potentially suitable habitat. N. spinosa was found only at the two previously known sites, which are ~36 km apart. The skink appears to be declining at Nangur NP, to an estimated extent of occurrence of 7.4 ha and potentially no more than 35 adults. In contrast, we increase the extent of occurrence at Oakview to 360 ha, where the population is at least in the hundreds. Sequencing of two mtDNA genes revealed considerable genetic divergence between the two populations (3.8% for ND4; 1.2% for 16S), suggesting an extended period of separation. Population fragmentation is therefore not the result of recent land clearing, but of long-term isolation by unsuitable habitat. Each population should be considered a distinct management unit. More data are required on population size and trends, recruitment and threats, particularly for the Nangur population.

The term, Working Knowledge, is introduced to describe the content of a local cross-cultural knowledge recovery and integration project focussed on the indigenous-owned Oriners pastoral lease near Kowanyama on the Cape York Peninsula, Queensland. Social and biophysical scientific researchers collaborated with indigenous people, non-indigenous pastoralists, and an indigenous natural resource management (NRM) agency to record key ecological, hydrological and geomorphological features of this intermittently occupied and environmentally valuable ‘flooded forest’ country. Working Knowledge was developed in preference to ‘local’ and/or ‘indigenous’ knowledge because it collectively describes the contexts in which the knowledge was obtained (through pastoral, indigenous, NRM, and scientific labour), the diverse backgrounds of the project participants, the provisional and utilitarian quality of the collated knowledge, and the focus on aiding adaptive management. Key examples and epistemological themes emerging from the knowledge recovery research, as well as preliminary integrative models of important hydro-ecological processes, are presented. Changing land tenure and economic regimes on surrounding cattle stations make this study regionally significant but the Working Knowledge concept is also useful in analysing the knowledge base used by the wider contemporary indigenous land management sector. Employees in this expanding, largely externally funded, and increasingly formalised sector draw on a range of knowledge in making operational decisions – indigenous, scientific, NRM, bureaucratic and knowledge learned in pastoral and other enterprises. Although this shared base is often a source of strength, important aspects or precepts of particular component knowledges must necessarily be deprioritised, compromised, or even elided in everyday NRM operations constrained by particular management logics, priorities and funding sources. Working Knowledge accurately characterised a local case study, but also invites further analysis of the contemporary indigenous NRM knowledge base and its relationship to the individual precepts and requirements of the indigenous, scientific, local and other knowledges which respectively inform it.

The distribution of the koala (Phascolarctos cinereus) and the common brushtail possum (Trichosurus vulpecula) within the Prairie-Torrens Creek Alluvials province of the Desert Upland region of north-western Queensland was examined. The optimum habitat for each species as indicated by the occurrence of faecal pellet groups was found to be that associated with creek-lines. However, other land types were also used by each species to varying degrees. The relationship between various habitat variables and pellet group counts was investigated using Multiple regression and a Generalised linear model. Proximity to creek-bed, total basal area of trees, species richness and Acacia basal area (negative) best explained the occurrence of koalas. Proximity to creek-bed, Acacia basal area (negative), total basal area of trees, and available water (negative) best explained the occurrence of brushtail possums. In contrast to studies of arboreal species in the moist-south-eastern forests of Australia no relationship was found between foliar nutrient concentrations and the occurrence of koalas or brushtail possums. However, a significant relationship was found between leaf water concentration and the occurrence of koalas. It is suggested that water availability is the paramount factor defining preferred arboreal habitat in arid and semi-arid woodlands.

The summer season of 2019–2020 has been named Australia’s Black Summer because of the large forest fires that burnt for months in southeast Australia, affecting millions of Australia’s citizens and hundreds of millions of animals and capturing global media attention. This extensive fire season has been attributed to the global climate crisis, a long drought season and extreme fire weather conditions. Our aim in this study was to examine the factors that have led some of the wildfires to burn over larger areas for a longer duration and to cause more damage to vegetation. To this end, we studied all large forest and non-forest fires (>100 km2) that burnt in Australia between September 2019 and mid-February 2020 (Australia’s Black Summer fires), focusing on the forest fires in southeast Australia. We used a segmentation algorithm to define individual polygons of large fires based on the burn date from NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS) active fires product and the Moderate Resolution Imaging Spectroradiometer (MODIS) burnt area product (MCD64A1). For each of the wildfires, we calculated the following 10 response variables, which served as proxies for the fires’ extent in space and time, spread and intensity: fire area, fire duration (days), the average spread of fire (area/days), fire radiative power (FRP; as detected by NASA’s MODIS Collection 6 active fires product (MCD14ML)), two burn severity products, and changes in vegetation as a result of the fire (as calculated using the vegetation health index (VHI) derived from AVHRR and VIIRS as well as live fuel moisture content (LFMC), photosynthetic vegetation (PV) and combined photosynthetic and non-photosynthetic vegetation (PV+NPV) derived from MODIS). We also computed more than 30 climatic, vegetation and anthropogenic variables based on remotely sensed derived variables, climatic time series and land cover datasets, which served as the explanatory variables. Altogether, 391 large fires were identified for Australia’s Black Summer. These included 205 forest fires with an average area of 584 km2 and 186 non-forest fires with an average area of 445 km2; 63 of the forest fires took place in southeast (SE) Australia (the area between Fraser Island, Queensland, and Kangaroo Island, South Australia), with an average area of 1097 km2. Australia’s Black Summer forest fires burnt for more days compared with non-forest fires. Overall, the stepwise regression models were most successful at explaining the response variables for the forest fires in SE Australia (n = 63; median-adjusted R2 of 64.3%), followed by all forest fires (n = 205; median-adjusted R2 of 55.8%) and all non-forest fires (n = 186; median-adjusted R2 of 48.2%). The two response variables that were best explained by the explanatory variables used as proxies for fires’ extent, spread and intensity across all models for the Black Summer forest and non-forest fires were the change in PV due to fire (median-adjusted R2 of 69.1%) and the change in VHI due to fire (median-adjusted R2 of 66.3%). Amongst the variables we examined, vegetation and fuel-related variables (such as previous frequency of fires and the conditions of the vegetation before the fire) were found to be more prevalent in the multivariate models for explaining the response variables in comparison with climatic and anthropogenic variables. This result suggests that better management of wildland–urban interfaces and natural vegetation using cultural and prescribed burning as well as planning landscapes with less flammable and more fire-tolerant ground cover plants may reduce fire risk to communities living near forests, but this is challenging given the sheer size and diversity of ecosystems in Australia.

Many mistletoe species are pests in agricultural and forest ecosystems throughout the world. Mistletoes are unusual “weeds” as they are generally endemic to areas where they achieve pest status and, therefore, classical biological control and broad-scale herbicidal control are usually impractical. In North American coniferous forests, dwarf mistletoe ( Arceuthobium spp.) infection results in major commercial losses and poses a public liability in recreation settings. Hyperparasitic fungi have potential as biological control agents of dwarf mistletoe, including species which attack shoots, berries, and the endophytic systems of dwarf mistletoe. Development of an inundative biological control strategy will be useful in situations where traditional silvicultural control is impractical or undesirable. In southern Australia, farm eucalypts are often attacked and killed by mistletoes ( Amyema spp.) in grazed landscapes where tree decline and biodiversity loss are major forms of land degradation. Although long-term strategies to achieve a balance between mistletoe and host abundance are promoted, many graziers want short-term options to treat severely infected trees. Recent research has revisited the efficiency and efficacy of silvicultural treatments and selective herbicides in appropriate situations. The results of recent research on these diverse management strategies in North America and Australia are summarized.

Because coral reefs are sensitive to land derived inputs of nutrient and sediment, there is concern worldwide for the effects of anthropogenic change in river catchments on reefs. Thirty-one river catchments drain directly into the waters of the Great Barrier Reef, NE Australia. This case study was undertaken on the floodplain of the Herbert River catchment in north Queensland, utilizing remote sensing and GIS to assess both spatial and temporal changes in freshwater wetlands and riparian forests. We demonstrate that there has been a very large reduction in the area of these ecosystems since European settlement in the mid nineteenth century, with an 80% decline in their extent since 1943. We provide a range of quantitative measures to show that the landscape diversity of these ecosystems has also declined. These changes are of importance in terms of regional, national and international trends. We argue that policy, planning and management reform is required if the remaining ecological, economic and social values of these systems and the adjacent Great Barrier Reef Marine Park are to be maintained.

This review examines the interactions between grasses and trees that are relevant to Queensland's grazing lands. Soils and climate determine the potential amount of woody vegetation within an area and clearing, fire and grazing management can modify that potential. In general, the presence of non-leguminous trees reduces the potential grass production beneath their canopy and within woodland patches. Some non-native leguminous trees (e.g. Indian siris, Albizia lebbeck) enhance production of grasses beneath their canopies, whereas the widespread native leguminous trees, mulga (Acacia aneura) and brigalow (A. harpophylla) have not been reported to enhance grass production in the same way. At the patch scale, pasture production beneath woodlands with moderate to high tree basal areas is generally less than in open patches under the same soil and climatic conditions. At a landscape level, tree density, rainfall amount and distribution, and soil type modify pasture production within forest/woodland/shrubland systems. Grasses can reduce tree seedling survival but have little impact on mature woody plants, apart from providing fuel to carry a fire. Modelling studies have been used to examine some aspects of tree-grass production. Firstly, the relationship between grass production and an increasing amount of trees can vary from linear decrease, to exponential decrease to initial stimulation followed by a decrease, depending solely on the relative strengths of stimulatory and competitive effects of trees on grasses. Secondly, simulated pasture production within woodlands shows that the pasture production may be up to 50% higher in paddocks that have high variability in the distribution of those trees compared with areas where trees are uniformly distributed. This is due to the non-linear (negative exponential) relationship between pasture production and tree density that is commonly observed within Queensland. Lastly, simulation studies show that total aboveground production (trees and pasture) of mulga woodland increases as the number of trees per hectare increases. The pasture production response to tree clearing or tree planting depends on tree species, rainfall, soil type, climatic history and post-clearing management including fire and grazing, and will change with time since clearing. The greatest relative increase in pasture production following the removal of woody vegetation occurs: when the initial tree basal area is highest; where rainfall is evenly distributed though the year and on fertile soils with a low water holding capacity.

Following a bait-preference pilot study on captive feral pigs, a series of field studies assessed the attractiveness and target-specificity of a prototype manufactured feral pig bait (PIGOUT®). Two promising test baits and fresh meat reference baits were biomarked with iophenoxic acid and aerially distributed in 100-km2 blocks of land infested with feral pigs in western Queensland to assess field uptake and target-specificity without prefeeding. Uptake was assessed by measuring blood iodine levels in aerially shot feral pigs. In all, 80% of feral pigs sampled in a non-toxic PIGOUT®-baited area had significantly elevated blood iodine, compared with 52% of sampled feral pigs in a meat-baited area (although slightly different baiting strategies were employed). No age or sex bias was evident in PIGOUT®-consuming feral pigs. No monitored manufactured baits were consumed by non-target species in 500 bait-nights. Attractiveness and target-specificity trials of ground-laid, unfenced PIGOUT® baits compared with reference baits were subsequently undertaken in several regions of eastern Australia. Results showed that PIGOUT® was consumed readily by feral pigs at all sites, and that it offered significant improvement in target specificity when compared with unfenced wheat or meat baits. However, the baits were consumed by small numbers of macropods, birds and possums. Available evidence indicates that the target-specificity of PIGOUT® bait is highest in the rangelands, reducing slightly in temperate areas and subalpine forests, where abundance of small animals is higher.

Context Mapping the habitat and distribution of a species is critical for developing effective conservation plans. Koala (Phascolarctos cinereus, Phascolarctidae) distribution is constrained by the nutritional and shelter requirements provided by a relatively small number of key tree species in any given area. Identifying these key species provides a practical foundation for mapping koala habitat and prioritising areas for conservation. Aims To determine key tree species for koalas in Noosa Shire (south-eastern Queensland, Australia) as a basis for mapping koala habitat quality. Methods We applied a faecal-pellet survey methodology in 1996/97 to assess evidence of use by koalas of 4031 trees from 96 randomly stratified survey sites across different eucalypt-forest and woodland communities. Results were compared with those from a later survey undertaken in 2001/02 involving 5535 trees from 195 sites that were distributed across broadly similar areas with the aim to investigate aspects of koala landscape ecology. Key results A total of 66.7% of the 1996/97 survey sites contained koala faecal pellets, recorded under 953 eucalypt trees (14 species) and 1670 non-eucalypt trees (27 species). The proportion of trees at a given survey site that had koala faecal pellets at the base ranged from 2.2% to 94.7% (mean = 31.13 ± 2.59% s.e.). For the 2001/02 dataset, koala pellets were found at 55.4% of sites, from 794 eucalypt and 2240 non-eucalypt trees. The proportion of trees with pellets ranged from 3% to 80% (mean = 21.07 ± 1.77% s.e.). Both the 1996/97 and 2001/02 surveys identified the same three tree species (forest red gum, Eucalyptus tereticornis, swamp mahogany, E. robusta, and tallowwood, E. microcorys) as the highest-ranked for koala use in the study area. Three additional species (red mahogany, E. resinifera, small-fruited grey gum, E. propinqua, and grey ironbark, E. siderophloia) were identified in the 1996/97 surveys as key eucalypt species. Of the non-eucalypts in the 1996/97 dataset, coast cypress pine (Callitris columellaris) and broad-leaved paperbark (Melaleuca quinquenervia) ranked highest for use by koalas, followed by pink bloodwood (Corymbia intermedia) and brush box (Lophostemon confertus). White bottlebrush (Callistemon salignus), hard corkwood (Endiandra sieberi), M. quinquenervia and C. intermedia ranked highest in the 2001/02 dataset. The findings showed significantly greater use of larger eucalypts (i.e. 300-mm to >600-mm diameter at breast height). Conclusions The identified key eucalypt species, being the critical limiting resource for koalas, were used to assign koala habitat-quality classes to mapped regional ecosystem types to create a Koala Habitat Atlas (KHA) for Noosa Shire. The combined two highest quality classes based on abundance of the key eucalypt species comprised only 15.7% of the total land area of the Shire. Implications The KHA approach provides a practical and repeatable method for developing koala habitat-suitability mapping for national-, regional- and local-scale conservation and recovery planning purposes.

Considerable research has been undertaken over the past two decades to apply remote sensing to the study of fire regimes across the savannas of northern Australia. This work has focused on two spatial scales of imagery resolution: coarse-resolution NOAA-AVHRR imagery for savanna-wide assessments both of the daily distribution of fires ('hot spots'), and cumulative mapping of burnt areas ('fire-scars') over the annual cycle; and fine-resolution Landsat imagery for undertaking detailed assessments of regional fire regimes. Importantly, substantial effort has been given to the validation of fire mapping products at both scales of resolution. At the savanna-wide scale, fire mapping activities have established that: (1) contrary to recent perception, from a national perspective the great majority of burning in any one year typically occurs in the tropical savannas; (2) the distribution of burning across the savannas is very uneven, occurring mostly in sparsely settled, higher rainfall, northern coastal and subcoastal regions (north-west Kimberley, Top End of the Northern Territory, around the Gulf of Carpentaria) across a variety of major land uses (pastoral, conservation, indigenous); whereas (3) limited burning is undertaken in regions with productive soils supporting more intensive pastoral management, particularly in Queensland; and (4) on a seasonal basis, most burning occurs in the latter half of the dry season, typically as uncontrolled wildfire. Decadal fine-resolution fire histories have also been assembled from multi-scene Landsat imagery for a number of fire-prone large properties (e.g. Kakadu and Nitmiluk National Parks) and local regions (e.g. Sturt Plateau and Victoria River District, Northern Territory). These studies have facilitated more refined description of various fire regime parameters (fire extent, seasonality, frequency, interval, patchiness) and, as dealt with elsewhere in this special issue, associated ecological assessments. This paper focuses firstly on the patterning of contemporary fire regimes across the savanna landscapes of northern Australia, and then addresses the implications of these data for our understanding of changes in fire regime since Aboriginal occupancy, and implications of contemporary patterns on biodiversity and emerging greenhouse issues.

Regrowth of native woody vegetation has the potential to provide an economically valuable source of carbon storage and other ecosystem services. There is a lack of readily applicable examples of how regrowth of forests and woodlands can be integrated with existing grazing production systems and provide soil-protection and water-retention benefits. A system of integrated vegetation bands (IVB) was applied to patchy regrowth of acacia and eucalypt vegetation in a grazed landscape of southern Queensland, Australia. Across a 39.8-ha catchment with 3–5% slope, regrowth of scattered native vegetation (18.4 ha) was surveyed and diameter at breast height and height for all woody plants were recorded. The IVB (6.3 ha) were then marked out as 25-m-wide bands set 100 m apart and offset at ~2–3% gradient to the contour line, retaining the densest/largest regrowth where possible. The data on diameter at breast height and height were analysed using allometric equations to compare aboveground biomass in the original regrowth condition (‘Original’) to that retained in the installed IVB (‘IVB-Riparian’). Estimates of aboveground biomass were calculated for the Original and IVB-Riparian and compared with three other potential regrowth-vegetation management ‘treatments’ in a desktop-modelling study. The models were designated as: (1) ‘Original’; (2) ‘Broad’ (broad-scale cleared with only a few large trees along a creek retained)’; (3) ‘Big Trees’ (only large trees >40 cm diameter at breast height retained); (4) ‘Riparian-IVB (bands of vegetation); and (5) ‘Riparian-IVB-Big Trees’ (large trees together with ‘IVB-Riparian’). In the non-forested area of the catchment, ‘Riparian-IVB-Big Trees’ (301 t), ‘Big Trees’ (249 t) and ‘Riparian-IVB’ (200 t) had the highest aboveground biomass retained, whereas ‘Broad’ resulted in the most pasture area (~33 ha) followed by ‘Riparian-IVB’ (~26 ha). The ‘Riparian-IVB’ treatment had the highest tree density within the vegetation bands and more than half (53%) of the original woody biomass in regrowth was retained on just under a quarter (23%) of the land area minimising the impact on the area of pasture/grazing land. This subsequently resulted in the ‘Riparian-IVB’ treatment having the highest carbon offset value (A$605 ha–1). The results demonstrate that the retention of native regrowth vegetation in either IVB or as large paddock trees can retain a large amount of aboveground biomass, with IVB having greater returns per hectare.

Selective logging is one of the main natural forest harvesting approaches worldwide and contributes nearly 15% of global timber needs. However, there are increasing concerns that ongoing selective logging practices have led to decreased forest product supply, increased forest degradation, and contributed to forest based carbon emissions. Taking cases of natural forest harvesting practices from the Tarai region of Nepal and Queensland Australia, this study assesses forest product recovery and associated carbon emissions along the timber production chain. Field measurements and product flow analysis of 127 commercially harvested trees up to the exit gate of sawmills and interaction with sawmill owners and forest managers reveal that: (1) Queensland selective logging has less volume recovery (52.8%) compared to Nepal (94.5%) leaving significant utilizable volume in the forest, (2) Stump volume represents 5.5% of total timber volume in Nepal and 3.9% in Queensland with an average stump height of 43.3 cm and 40.1 cm in Nepal and Queensland respectively, (3) Average sawn timber output from the harvested logs is 36.3% in Queensland against 61% in Nepal, (4) Nepal and Queensland leave 0.186 Mg C m−3 and 0.718 Mg C m−3 on the forest floor respectively, (5) Each harvested tree damages an average of five plant species in Nepal and four in Queensland predominantly seedlings in both sites, and (6) Overall logging related total emissions in Queensland are more than double (1.099 Mg C m−3) those in Nepal (0.488 Mg C m−3). We compared these results with past studies and speculated on possible reasons for and potential implications of these results for sustainable forest management and reducing emissions from deforestation and forest degradation.

Wetlands are one of the most biologically productive ecosystems. Wetland ecosystem services, ranging from provision of food security to climate change mitigation, are enormous, far outweighing those of dryland ecosystems per hectare. However, land use change and water regulation infrastructure have reduced connectivity in many river systems and with floodplain and estuarine wetlands. Mangrove forests are critical communities for carbon uptake and storage, pollution control and detoxification, and regulation of natural hazards. Although the clearing of mangroves in Australia is strictly regulated, Great Barrier Reef catchments have suffered landscape modifications and hydrological alterations that can kill mangroves. We used remote sensing datasets to investigate land cover change and both intra- and inter-annual seasonality in mangrove forests in a large estuarine region of Central Queensland, Australia, which encompasses a national park and Ramsar Wetland, and is adjacent to the Great Barrier Reef World Heritage site. We built a time series using spectral, auxiliary, and phenology variables with Landsat surface reflectance products, accessed in Google Earth Engine. Two land cover classes were generated (mangrove versus non-mangrove) in a Random Forest classification. Mangroves decreased by 1480 hectares (−2.31%) from 2009 to 2019. The overall classification accuracies and Kappa coefficient for 2008–2010 and 2018–2020 land cover maps were 95% and 95%, respectively. Using an NDVI-based time series we examined intra- and inter-annual seasonality with linear and harmonic regression models, and second with TIMESAT metrics of mangrove forests in three sections of our study region. Our findings suggest a relationship between mangrove growth phenology along with precipitation anomalies and severe tropical cyclone occurrence over the time series. The detection of responses to extreme events is important to improve understanding of the connections between climate, extreme weather events, and biodiversity in estuarine and mangrove ecosystems.

Scenario planning was used to develop a consensus-based, multi-stakeholder management planning process for a 114 000 ha land base in New Brunswick, Canada. This is part of the Fundy Model Forest, which involves four major landowner groups, along with 26 other Partnership organizations. Public consultation and Partnership input were used to define 25 scenarios, determining effects of alternative means of riparian strip management, road construction, vegetation and insect control, harvesting, maintenance of biodiversity, and plantation establishment. The Woodstock forest modelling software was used to determine effects of each scenario on timber supply, forest structure, measures of biodiversity and ecological integrity, areas of mature forest, and wildlife habitat. In a series of workshops, the Partners were successful in reaching consensus on a Fundy Model Forest "preferred" management scenario, which was conveyed to the land managers for implementation. Development of the management planning process and the use of scenario planning procedures in the Fundy Model Forest are described. Key words: scenario planning, sustainable forest management, Fundy Model Forest, timber supply, biodiversity

This paper investigated the utility of drone-based environmental monitoring to assist with forest inventory in Queensland private native forests (PNF). The research aimed to build capabilities to carry out forest inventory more efficiently without the need to rely on laborious field assessments. The use of drone-derived images and the subsequent application of digital photogrammetry to obtain information about PNFs are underinvestigated in southeast Queensland vegetation types. In this study, we used image processing to separate individual trees and digital photogrammetry to derive a canopy height model (CHM). The study was supported with tree height data collected in the field for one site. The paper addressed the research question “How well do drone-derived point clouds estimate the height of trees in PNF ecosystems?” The study indicated that a drone with a basic RGB camera can estimate tree height with good confidence. The results can potentially be applied across multiple land tenures and similar forest types. This informs the development of drone-based and remote-sensing image-processing methods, which will lead to improved forest inventories, thereby providing forest managers with recent, accurate, and efficient information on forest resources.

Abstract Forest and Land Rehabilitation is one of the right solutions to overcome the problem of critical land. Efforts to overcome critical land are difficult to obtain in a short time to return the situation to its original state, but efforts are being made by the government to overcome the existence of critical land and the expansion of critical land, including through land conservation and reforestation. This study aim to determine the success of plants in a forest and land rehabilitation program in the village of Datar Lebuay in the Air Naningan district of Tanggamus regency. The study was carried out in June 2021. Field data collection was carried out by making plots using the Systematic Sampling with Random Start method, namely the first plot was made randomly and the next plots were made systematically. Sampling Intensity (IS) is 5%. The results showed that the success rate of RHL activities with a percentage of life was 79.74% which was classified as successful. Factors that are thought to influence the low success rate of plants are the condition of the planted seeds that are already in a damaged state and the planting season is not right.

Great Barrier Reef catchments are under pressure from the effects of climate change, landscape modifications, and hydrology alterations. With the use of remote sensing datasets covering large areas, conventional methods of change detection can expose broad transitions, whereas workflows that excerpt data for time-series trends divulge more subtle transformations of land cover modification. Here, we combine both these approaches to investigate change and trends in a large estuarine region of Central Queensland, Australia, that encompasses a national park and is adjacent to the Great Barrier Reef World Heritage site. Nine information classes were compiled in a maximum likelihood post classification change analysis in 2004–2017. Mangroves decreased (1146 hectares), as was the case with estuarine wetland (1495 hectares), and saltmarsh grass (1546 hectares). The overall classification accuracies and Kappa coefficient for 2004, 2006, 2009, 2013, 2015, and 2017 land cover maps were 85%, 88%, 88%, 89%, 81%, and 92%, respectively. The cumulative area of open forest, estuarine wetland, and saltmarsh grass (1628 hectares) was converted to pasture in a thematic change analysis showing the “from–to” change. We generated linear regression relationships to examine trends in pixel values across the time series. Our findings from a trend analysis showed a decreasing trend (p value range = 0.001–0.099) in the vegetation extent of open forest, fringing mangroves, estuarine wetlands, saltmarsh grass, and grazing areas, but this was inconsistent across the study site. Similar to reports from tropical regions elsewhere, saltmarsh grass is poorly represented in the national park. A severe tropical cyclone preceding the capture of the 2017 Landsat 8 Operational Land Imager (OLI) image was likely the main driver for reduced areas of shoreline and stream vegetation. Our research contributes to the body of knowledge on coastal ecosystem dynamics to enable planning to achieve more effective conservation outcomes.

This study set out to assess the dynamic characteristics of the Ikere forest reserve landscape between 1985 and 2017 using remote sensing data and spatial metrics. Landscape of the study area maintained complex patterns of spatial heterogeneity over the years. Forest cover loss to other land cover types results in new large non-forest area at increasing rate. As at the year 2017, the changes in land cover types were not yet at equilibrium, thus the need to determine the future forest cover extent using a three-way markov Chain model. The decrease in number of patches of forest land (NumP) with increase in its mean patch size (MPS) shows that the forest is becoming a single unit probably due to clearing of existing patches of forest trees. The decrease in class diversity and evenness (SDI and SEI) of the general landscape over the years strengthens this assertion. The findings of this study would be very helpful to government and other stakeholders responsible for ensuring sustainable forest and general environment.

In Australia, regional forest agreements formed the cornerstone of strategies for resolving disputes over the logging of native forests in the last decade of the twentieth century. These disputes, driven by an increasingly vocal and influential conservation movement, coincided with changes in the nature of relationships between Commonwealth and State Governments, with the Commonwealth adopting an increasing role in environmental management (Lane 1999). Following very public disputes about the renewal of export woodchip licenses from native forests (which culminated in log truck blockades of the Commonwealth Parliament, Canberra), the Commonwealth Government adopted regional forest agreements as the mechanism for achieving sustainable management of Australia?s native hardwood forests. This was underpinned by the National Forest Policy Statement (Commonwealth of Australia 1992), which outlined principles for ecologically sustainable management of the nation?s production forests. The Commonwealth and several State Governments reached agreement to develop regional forest agreements (RFAs) for the long-term management and use of forests in ten regions (Fig. 1) (Commonwealth of Australia 2004). Key goals of the agreement were to: reconcile competing commercial, ecological and societal demands on forests in a way that was consistent with the principles and goals of ecologically sustainable forest management (Davey et al. 1997, 2002; Lane 1999); and to establish a comprehensive, adequate and representative reserve system, based on the nationallyagreed JANIS criteria (JANIS 1997).

In keeping with international efforts to encourage sustainable forest management, new legislation, regulations, and certification criteria have been brought into effect across boreal regions of the world in the past decade or less. These initiatives have established hierarchical systems of forest management planning that consider multiple uses of the forest and various aspects of sustainable forest management at different scales. We describe the systems established in Quebec, Ontario, Saskatchewan, Alberta, and British Columbia, Russia, Finland, and Sweden. Most jurisdictions employ some form of three-level planning framework, in which strategic, tactical, and operational plans and considerations are presented with successively greater detail and spatial explicitness. However, planning scales and time horizons vary considerably, as does the level of consideration given to biodiversity and social concerns. We examine these systems in the context of sustainable forest management, raising a number of questions to be addressed in future research, adaptive management, and policy reform. In particular, we note (1) a need of new landscape and regional planning tools to evaluate the long-term and large-scale impacts of various land uses and (2) a general lack of responsiveness to global carbon and climate change concerns. Key words: forest management planning, sustainable forest management, boreal forest, forest policy, planning hierarchies, hierarchical planning

Coastal, reef-associated and deepwater (> 15 m) seagrass habitats form a large and ecologically important community on the Queensland continental shelf. Broad-scale resource inventories of coastal seagrasses were completed in the 1980s and were used in marine park and fisheries zoning to protect some seagrasses. At least eleven of the fifteen known species in the region reach their latitudinal limits of distribution in Queensland and at least two Halophila species may be endemic to Queensland or northeastern Australia. The importance of seagrasses to Dugongs Dugong dugon, Green Turtles Chelonia mydas and commercially valuable prawn fisheries, will continue to strongly influence directions in seagrass research and conservation management in Queensland. Widespread loss of seagrasses following natural cyclone and flood events in some locations has had serious consequences to regional populations of Dugong. However, the impacts to Queensland fisheries are little studied. Agricultural land use practices may exacerbate the effects of natural catastrophic events, but the long-term impacts of nutrients, pesticides and sediment loads on Queensland seagrasses are also unknown. Most areas studied are nutrient limited and human impacts on seagrasses in Queensland are low to moderate, and could include increases in habitat since modern settlement. Most impacts are in southern, populated localities where shelter and water conditions ideal for productive seagrass habitat are often targets for port development, and are at the downstream end of heavily modified catchments. For Queensland to avoid losses experienced by other states, incremental increases in impacts associated with population and development pressure must be managed. Seagrass areas receive priority consideration in oil spill management within the Great Barrier Reef and coastal ports. Present fisheries legislation for marine plant protection, marine parks and area closures to trawl fishing help protect inshore seagrass prawn nursery and Dugong feeding habitat, but seagrasses in deep water do not yet receive any special zoning protection. Efficacy of the various Local, State and Commonwealth Acts and planning programmes for seagrass conservation is limited by the expanse and remoteness of Queensland's northern coast, but is improving through broad-based education programmes. Institutional support is sought to enable community groups to augment limited research and monitoring programmes with local "habitat watch" programmes. Research is helping to describe the responses of seagrass to natural and human impacts and to determine acceptable levels of changes in seagrass meadows and water quality conditions that may cause those changes. The management of loss and regeneration of sea grass is benefiting from new information collected on life histories and mechanisms of natural recovery in Queensland species. Maintenance of Queensland's seagrasses systems will depend on improved community awareness, regional and long-term planning and active changes in coastal land use to contain overall downstream impacts and stresses.

Forest land use planning in Alberta takes place within the provincial Integrated Resource Planning system. The Alberta Forest Service is a major participant in this system as it is the primary resource management agency for Alberta's forested land. Several provincial land use policies direct forest-related land use, including the White and Green Areas, established in 1948, and the Eastern Slopes Policy adopted in 1977. More detailed and site specific resource management is guided through subregional and local planning. In total, these planning mechanisms provide for the comprehensive and integrated management of Alberta's forested land. Key words: Forest land use planning, integrated planning, planning in Alberta, resource management.

An increasing human population is exerting greater demands upon the earth for resource production and living space. Despite its large landmass, Canada is not immune to this pressure. On industrial forested lands, one response has been integrated resource management, whereby the forest supports multiple uses within the same space and time. Under the strain of increasing pressures, coupled with a concern for the maintenance of natural systems and processes, it has become evident that the current planning processes need to evolve to incorporate a new land management paradigm. This paper outlines the issues and presents for discussion a potential management paradigm based not only on the limited scope of industrial forested lands but on the broader expanse of land management in general. Supporting the proposed Integrated Land Management (ILM) approach, Millar Western Forest Products Ltd., an Alberta-based forest products company, developed a cumulative effects assessment to complement its forest management plan. This assessment demonstrates that as a proof of concept, ILM is technically achievable and can be scientifically based. Further, integration of diverse concepts and disciplines can be organized to produce functional plans. Key words: Integrated Land Management, Integrated Resource Management, forest management, cumulative effects assessment

A forest land evaluation was made in the upper Kali Konto watershed in E. Java (Indonesia). The suitability of 155 Land Mapping Units for each of 13 Land Utilization Types was rated by standard procedures developed for rural land evaluation. A new concept of quantified 'land-use policy option' was introduced, being a theoretical combination of LUTs showing quantitatively, for the area as a whole, the consequences of a particular policy. The options are quantified by further specification of the LUTs in terms of one or more forest management models. The policies themselves comprise not only extremes such as 'conservation', 'population [needs]' or 'financial return' but also 'integrated' policies. In this case it is shown that an integrated land-use pattern could be developed to guarantee conservation of resources while largely meeting the demands of the local population for fuelwood and light timber and also yielding direct monetary benefits.

The quest to foster sustainable forest management (SFM) in the era of sustainable development goals has reignited the debate on forest tenure concerns. Land and forest tenure insecurity has remained a major underlying cause of deforestation in Africa, which suggests that addressing tenure issues could effectively foster sustainable forest management. Adopting theoretical literature and drawing lessons from related empirical works, this study examines the role of land and forest tenure in sustainable forest management drive. Among other things, the study discusses how land tenure promotes or inhibits sustainable forest practices. The study outlines how frustrating tenure regimes deprive the community of the needed benefits and subsequent untoward behaviour unleashed on forests. The study concludes that the idea of tenure rights and tenure security has implications on sustainable forest management and admonishes a robust tenure regime that upholds local 'people's access to and usage of forest resources without sinister machinations and subjugation of local people. The study contends that determined rights and their long-term security remain crucial in attracting the tenure holders to make a strenuous investment in SFM since investments in forestry usually are made for the long term. Among other things, the study recommends for clarity and long-term security of ownership and tenure rights regarding forest products; a need to promote capacity-building for administrators and rights holders to adopt a sustainable mindset in their exploitation of timber products; and a need to foster stakeholder participation.

Studies of materials and indicators on accounting and coverage of information on land management and forest management of state forestry in Ukraine. Certain inconsistencies of the current normative legal acts and indicators of the state and dynamics of the accounting category of land use «Forestry lands» were revealed. In particular, regarding the assessment of rational use and protection of lands, which are the basis for the implementation of the Land Reform. There are, in particular, in the form 6 — ZEM and in the materials of the state account, not modernized terms and their description. The category of accounting «Forestry lands» in the Land and Forest Codes of Ukraine, in the scientific and practical lexicon did not receive due attention and distribution as an object of labor, an object of identified land use in state forestry. Do not match the description in the Forest and Land Codes of Ukraine. The issue of organizational and economic accounting of land of the accounting category «Forestry lands» remains poorly regulated. The annual report still retains the description — «Forest lands include lands covered with forest vegetation, as well as not covered with forest vegetation and others» for forestry purposes». The category of accounting «Forestry lands» in the Land and Forest Codes of Ukraine, in the scientific and practical lexicon did not receive due attention and distribution as an object of labor, an object of identified land use in state forestry. Do not match the description in the Forest and Land Codes of Ukraine. The category of accounting for «Forestry lands» is placed in Article 19 of the Land Code of Ukraine under item «e», i.e. in 7th place, which does not comply with current principles of European legislation, not to mention the physical aspects of forest distribution in Ukraine. Again, the practice in Ukraine faces deadlines. It turns out that forestry science is increasingly moving away from the identified responsibilities and reporting of public forestry entities. The industry is less and less monitoring the state of forests according to estimates of the use of productive capacity of land by types of forest vegetation conditions. It turns out that forestry science is increasingly moving away from the identified responsibilities and reporting of public forestry entities. The industry is less and less monitoring the state of forests according to estimates of the use of productive capacity of land by types of forest vegetation conditions. In addition, the management in the state forestry in its powers only «ensures the implementation of state policy in the field of forestry and hunting», does not form it. That is, it does not develop relevant regulations, which is a certain flaw in the current forest legislation and needs to be changed. Specific measures are proposed to improve the legislation, accounting and state reporting in forestry, as well as the basic scheme of division of forest lands by accounting categories of division and administrative reporting of forestry and other enterprises of the State Forestry Agency of Ukraine.

Abstract The management of protection forests in KPH Yogyakarta has involved the surrounding community. Community involvement is expected to keep forest sustainability and contribute to the surrounding community’s income. Community engagement activities in the protection forest at RPH Mangunan have been developed long time before the KPH Yogyakarta was formed. Several social forestry activities was designed by utilizing forest land to involve the community in protection forests, especially in RPH Mangunan. Activities with the community on KPH land are permitted as long as the crops and trees are not disturbed. This paper aims to identify community involvement in RPH Mangunan and calculate the economic contribution of each land area used by the community. The research was conducted in July-August 2018. The collection of socio-economic data are obtained through household surveys of KPH land users, in-depth interviews with key stakeholders and Focus Group Discussion (FGD) of parties involved in KPH land management. The income from managing the KPH land is still below the needs of one household based on Yogyakarta provincial minimum wage. Apart from carrying out agricultural activities, some community members have other sources of livelihood. To increase the community’s income and support forest sustainability, some strategies need to be implemented.

In a 5-yr (1979-84) study of 6 species of fruit pigeon in lowland (dry) and upland (wet) subtropical rain forests in the Jimna and Conondale Ranges, the effects of forest phenology on pigeon abundance were investigated. The pigeons utilized 89 species of plants from 39 families of trees, palms and vines. The seasonal availability of fruit was similar in each forest type: most plant species bore crops during the wet season (Dec.-Mar.) and held crops into the early dry season (April-May); the late dry season (June-Oct.) was a time of general fruit shortage. More than 60% of the species of food plants present in upland forest were rare or absent in lowland forest. In general, each species of pigeon utilized a distinct suite of plant species in each forest type. Certain species of fig (Ficus spp.) fruited asynchronously and were the most important food for sedentary wompoo fruit-doves (Ptilinopus magnificus magnificus) in both forest types. These and other species of fig were the most important food for topknot pigeons (Lopholaimus antarcticus) and rose-crowned fruit-doves (P. regina regina) in lowland forest. An influx of flocks of up to 200 topknot pigeons into upland forest occurred each year in response to the fruiting of Archontophoenix cunninghamiana. The foraging habits of rose-crowned fruit-doves were largely opportunistic in upland forest, utilizing whatever fruit was available at particular times. White-headed pigeons (Columba leucomela) foraged solely in Olea paniculata during irregular visits to lowland forest. A regular summer influx into upland forest occurred in response to the fruiting of a vine, Piper novae-hollandiae. In each forest type, brown cuckoo-doves (Macropygia amboinensis) had a distinct foraging preference for plant species characteristic of disturbed forests; important plant families were the Solanaceae, Ulmaceae, Euphorbiaceae and Araliaceae. Superb fruit-doves (P. superbus) were seldom found in either forest type.
