Streszczenie:
Analyses of carbon, nitrogen and phosphorus in heathland soils at Wilsons Promontory and on Snake Island show that the effects of fire, including repeated fires, are confined to the surface 2 cm. The uppermost soil in long-unburnt heathlands is rich in these elements and usually has a smaller C:N ratio compared with the soil below. Indices of N and P availability (C:N ratios, concentrations of potentially mineralisable N and extractable inorganic P, phosphatase activity) are similar to those in highly productive eucalypt forests-a finding in conflict with past assessments of nutrient availability in heathlands. Phosphatase activity and concentrations of carbon, nitrogen and potentially mineralisable N were less in soils from repeatedly burnt heathlands than in soils from long unburnt heathlands whereas there was a greater concentration of extractable inorganic P in soils from repeatedly burnt heathlands. The balance between nitrogen input and loss is dependent on fire frequency and present-day management of heathland (and other native plant communities with low nutrient capitals) should recognise that over- or under-use of fire will significantly alter soil nutrient pools and availability and that these changes may alter community species composition and productivity.

Streszczenie:
Six heathland sites were studied in Cooloola National Park, south-eastern Queensland. Vegetation composition (species present and numbers) and structure (plant density, cover, height and vertical foliage density) were examined at each site with respect to time since last fire (0.5-10.5 years) and the two recognised microhabitat types (dry and wet). No significant change in species numbers or composition was detected in sites more than 1 year after fire, although the changing physical status (density and cover) of some plants could give the impression of species being 'lost' or 'gained' over time. On the basis of the structural attributes of the heathlands, and the maintenance of several obligate seed regenerator species, a minimum fire-free interval of 8 or 10 years is suggested for subtropical heathlands. Results from this study are compared with data collected from other Australian heathlands. In composition and structure, the temporal responses to fire in the Cooloola heathlands are similar to those in southern heathlands, albeit occurring at a possibly faster rate.

The timing and intensity of flowering and seeding of most subtropical heathland plants were examined in five sites that had been unburnt for different lengths of time. For the heathlands in general, most flowering occurs in spring. For those species examined, seed intensity is also greatest in spring. The numbers of species flowering and seeding, and the intensity of these activities, increase to a peak between 4 and 8 years after a fire. There appears to be a decline in reproductive effort in heathlands unburnt for more than 10 years but the data are limited. The percentage of the total heathland flowering and seeding intensity in the dry microhabitat peaks between late autumn and spring. In the wet microhabitat the percentage is greatest between summer and mid autumn. Flower and subsequent seed intensity varies within and between heathland microhabitats on both within-year (seasonal) and between-year (years since last fire) time scales.

A description and analysis of the vascular plant composition of heathlands in the Annapolis valley were undertaken to provide a basis for biodiversity preservation within a system of protected sites. Species presence and abundance were recorded at 23 remnant sites identified using topographic maps, air photos, and Nova Scotia Department of Natural Resources records. A total of 126 species was recorded, of which 94 were native and 31 introduced. The Annapolis heathland remnants are strongly dominated by Corema conradii with Comptonia peregrina, Vaccinium angustifolium and Pteridium aquilinum var. latiusculum. A number of species, including Solidago bicolor, Carex tonsa var. rugosperma, Dichanthelium depauperatum, Lechea intermedia, Melampyrum lineare, and Rubus hispidus, were characteristic of heathland remnants, although they usually contributed little to the total cover. The most frequent alien species were Hieracium pilosella and Festuca filiformis, but Pinus sylvestris, present at 7 of 18 sites, appeared to have the greatest impact in displacing native species. Species listed as at risk and sensitive in Nova Scotia, including Helianthemun canadense, Hudsonia ericoides and Viola sagittata var. ovata, occur in open disturbed sand in the Corema heathlands. Distinctive patterns of variation occur in several species and variation in crop relatives is noted with particular reference to the genera Rubus (blackberries), Amelanchier (Juneberries, Saskatoon) and Vaccinium (Blueberries). The available evidence suggests that the heathlands and sandy barrens in the Annapolis valley differ from those further west in Canada and from anthropogenic and coastal heathlands of Nova Scotia in their species composition including particularly the presence of Corema conradii, Hudsonia ericoides and Amelanchier lucida. The need to protect representative examples is supported.

Conservation priorities and decisions can be informed by understanding diversity patterns and the evolutionary history of ecosystems, and phylogenetic metrics can contribute to this. This project used a range of diversity metrics in concert to examine diversity patterns in the Sunshine Coast heathlands, an ecosystem under intense pressure. The species richness and composition of 80 heathland sites over nine regional ecosystems of heathland on the Sunshine Coast were enhanced with phylogenetic metrics, determined by barcoding 366 heath species of the region. The resulting data were added to an existing phylogeny of regional rainforest species. The diversity metrics for sites and regional ecosystems were compared using univariate and multivariate statistics. The phylogeny from this study, and the low phylogenetic diversity of the heathlands, is consistent with the theory that heath species evolved on the fringes on a wider Australian rainforest flora. Distinctive heathland communities were highlighted, and the existence of geographically scattered, but compositionally similar, phylogenetically even sites points to a possible “refugial environment”, characterised by moisture and instability. This suggests contrasting conservation implications: the protection of distinctive communities but also the management of the dynamic processes in other wet and alluvial “refugial environments”. The potential for more focused conservation priorities is enhanced.

Streszczenie:
Ground parrots in Queensland were found in closed graminoid-heathlands and sedgelands between Maryborough and Coolum on the mainland, and along the west coast of Fraser I. Parrot distribution, when compared to historical data, shows a decline which is a result of habitat destruction or degradation in the northern and southern limits of the species range. The current population is estimated at 2900 birds, with the majority in the heathlands of Cooloola National Park, Wide Bay Military Reserve and the State Forest and the Great Sandy National Park on Fraser I. Ground parrot density varied between sites because of the interactive effects of vegetation type, heathland area, time since and frequency of fire, microhabitat diversity and proximity to recolonisers. Within sites, parrot numbers changed in the long term with time since fire (influence of temporal changes in vegetation structure and seed availability) peaking at 5-8 years after burning, and in the short term with the seasonal effects of dispersal and breeding. Although predators were present their impact on the main populations was considered minimal. All of these factors are, to some extent, influenced by human activities, e.g. clearing and burning of heathlands.

Calluna vulgaris-dominated heathlands are globally important habitats and extremely scarce outside of north-west Europe. Rotational fire, grazing and cutting by local farmers were dominant features of past heathland management throughout Europe but have been abandoned, altering the historical fire regime and habitat structure. We briefly review research on Calluna heathland conservation management and provide the background and methodology for a long-term research project that will be used to define prescribed fire regimes in combination with grazing and cutting, for management of Calluna heathlands in north-west Italy. We outline the ecological and research issues that drive the fire experiment, making explicit the experimental design and the hypotheses that will be tested. We demonstrate how Adaptive Management can be used to inform decisions about the nature of fire prescriptions where little formal knowledge exists. Experimental plots ranging from 600 to 2500 m2 are treated according to one of eight alternative treatments (various combinations of fire, grazing and cutting), each replicated four times. To date, all treatments have been applied for 4 years, from 2005 to 2008, and a continuation is planned. Detailed measurement of fire characteristics is made to help interpret ecological responses at a microplot scale. The results of the experiment will be fed back into the experimental design and used to inform heathland management practice in north-west Italy.

In the northwest of the Iberian Peninsula, characterized by its humid climate, large rural areas are being abandoned, mostly in less-favoured areas covered by heathlands, which present a low nutritive quality for livestock production. The high combustibility of these shrublands is driving a high wildfire incidence with negative environmental and economic effects. In this review, some aspects on wildfire occurrence and the potential of grazing livestock to reduce woody phytomass and fire risk in heathland-dominated areas whilst maintaining quality production and preserving biodiversity are summarized. Heathlands may be partially improved—converted to grassland—to better meet animals’ nutritional requirements while acting as ‘natural’ firebreaks. The specific grazing behaviour offers the opportunity to combine different domestic herbivores (mixed grazing) to achieve sustainable systems utilizing heterogeneous resources. Cattle, sheep, goats, and horses may have a role in the provision of different ecosystem services such as food production and biodiversity conservation. Genotype x environment interactions shape the ability of animals to cope with poor vegetation conditions, with smaller species and breeds performing better than larger animals. Goats and horses are indicated to arrest woody encroachment. Sustainable grazing systems are affordable in heathland–grassland mosaics by selecting appropriate livestock species and breeds for quality production, thus favouring rural economies and lowering fire risk.

Streszczenie:
Calluna vulgaris-dominated heathlands are a priority habitat type in Annex I of the Habitats Directive (92/43/ECC, habitat code 4060). In the Iberian Peninsula, the landscape of the Cantabrian Mountain range has great heterogeneity due to human management during the last 10,000 years. Another factor that can affect these communities is the increase in human-induced atmospheric nitrogen (N) deposition. During the last century, there has been a dramatic increase in N deposition rates. For all these reasons, it is important to know the regeneration dynamics of the heathlands in the context of the disturbances that these communities currently face (i.e., N deposition, fire, and decrease in sheep grazing) in the Cantabrian Mountain range. In this study, we characterized the plant species composition and soil seed bank after prescribed burning in three heathlands on their southern distribution limit in Spain, to gain insights into regenerative capacity and conservation of these communities. The results obtained suggest that the post-burn soil seed bank could restore Calluna-dominated vegetation in these habitats, indicating that the restoration potential from the soil seed bank after wildfires of these habitats is high. Our results also suggest that, in the short term after burning, the main characteristic species such as Calluna and Erica are recovered, which is fundamental to maintain the heathland community structure.

This study investigated the effects of habitat clearance and fragmentation on birds of coastal heathlands in subtropical eastern Australia. Abundance and species composition were compared among two types of cleared habitat (residential suburbs and sugar cane cropland) and four sizes of heathland remnant (1–2 ha, 5–10 ha, 20–50 ha and >500 ha) in summer and winter. Cleared land contained a distinctly different bird species assemblage from heathland remnants. Residential sites contained a distinct suite of species consistent with that described for ‘open/developed land’ habitat elsewhere in the region. In contrast, cane cropland supported very few species. Heathland remnants >500 ha contained high densities of ‘natural-vegetation-dependent’ species, whereas species of open/developed land were absent. Remnants of 1–2 ha had lowered densities of many natural-vegetation-dependent species, and a relatively high abundance of open/developed land species. Some of the avifaunal differences in the >500-ha remnants and 5–50-ha range are probably due to confounding of remnant size with habitat, resulting from selective clearing of the landscape. Most of the heathland birds were intolerant of the matrix habitat (residential and cane cropland), but tolerant of decreased remnant area, down to a threshold of about 5 ha. However, the distinctive floristic associations of heathland vegetation are dependent on an environmental regime (low nutrient, low pH, fire, in some cases inundation) that is unlikely to persist in remnants tens of hectares in size, and longer-term declines in heathland birds, are predicted.

Streszczenie:
Despite widespread conservation efforts, global heathland area has substantially decreased in recent decades. Heathland habitats require low nitrogen availability in order to persist. Over the past 150 years, however, nitrogen deposition has increased markedly. Early observational studies and research using artificial N applications have identified N deposition as the primary driver of heathland succession into grassland or woodland, and N enrichment is considered a threat to heathland sustainability. This study investigated soil fertility and vegetation composition at 25 lowland heathland sites in low rainfall regions of mainland Britain within a modelled wet N deposition range of 1.85 to 10.90 kg N ha-1 y-1. A bioassay approach was used to quantify relationships between soil fertility and N deposition, heathland patch size and the management regimes. This study discovered significant positive relationships between N enrichment and C. vulgaris shoot mass, N and P concentrations. No relationship between N enrichment and N : P mass ratio was found suggesting no N induced shift to P limitation. It was determined that soil phosphomonoesterase activity was not up-regulated in response to N enrichment. This suggests that the soil P reserves are sufficient to satisfy demand under current N deposition loads. Heathland patch size was negatively related to C .vulgaris shoot dry-mass which was used as a proxy for soil fertility. Measured atmospheric ammonia concentrations were not related to C. vulgaris growth and shoot chemistry. No relationships were found between any variable tested and heathland vegetation composition suggesting that local factors, such as management intervention, may be substantial determinants of vegetation composition. This study presents relationships between temperature at origin and C. vulgaris growth from populations located along a latitudinal gradient in Western Europe. The findings of this thesis have implications for current heathland management, and for future management under a climate change scenario.

Streszczenie:
Massachusetts sandplain heathlands are habitats of conservation concern, harboring many rare plant species and providing habitat for animals that depend on openlands. These heathlands are threatened by human development, shrub encroachment in the absence of disturbance, and potentially increasing soil nutrient levels. Sandplain heathlands are managed with prescribed fire, in order to maintain their open structure and maintain species diversity. In order to assess how past management was correlated with species change, I used a data set that spanned twenty years from three different heathlands in Massachusetts. I looked for correlations between management and species change. Correlations between species change and prescribed burning were very site, or microsite, specific, indicating that variables such as vegetation type and edaphic characteristics need to be taken into account before management is applied. Prescribed fire was also associated with an increase in ruderal species in one of the sites studied, indicating that there may be undesirable effects of prescribed fire in this system. Species diversity was negatively associated with shrub encroachment, reinforcing the importance of preventing shrubs from encroaching into these heathlands. I also found evidence that burning has not been a successful technique in preventing shrub encroachment in these sites. Lastly, the nitrophilic species Carex pensylvanica increased in all three sites, indicating that future studies should investigate the possibility that sandplain heathlands are currently experiencing nitrogen deposition beyond their critical loads.

Streszczenie:
In England, the loss of lowland heathland, a habitat of high conservation importance, is primarily due to the invasion of birch and pine. This secondary succession has been researched in depth from a plant perspective but little is known about the role of mycorrhizal fungi, even though both trees and heather are mycorrhizal. In fact, tree encroachment onto lowland heathland can be regarded as the replacement of a resident ericoid mycorrhizal community by an invading ectomycorrhizal community. I determined the identity and distribution of the ectomycorrhizal fungi associated with birch and pine encroachment onto lowland heathlands. I established whether there are mycorrhizal fungi that mediate the invasion by a) comparing the mycorrhizal inoculum potential of soil and ectomycorrhizal fungal diversity at three levels of invasion (uninvaded heathland, invaded heathland and woodland), b) comparing the fungi forming mycorrhizas on tree seedlings and trees across diverse sites, c) determining the effect of proximity to trees on mycorrhization and seedling biomass, and d) identifying fungal dispersal methods. I established that in lowland heathlands i) seedlings have limited access to ectomycorrhizal fungi even within sapling rooting zones, ii) ectomycorrhizal inoculum potential increases as the level of tree invasion increases, iii) mycorrhizal seedlings accumulate more biomass than non-mycorrhizal seedlings, iv) there are five keystone ectomycorrhizal fungi that participate in tree invasion - Rhizopogon luteolus, Suillus bovinus, S. variegatus (pine symbionts), Laccaria proxima and Thelephora terrestris (primarily birch symbionts), v) some ectomycorrhizal fungi cannot colonise seedlings via spores, and vi) ectomycorrhizal communities differ between lowland heathland sites. This study is the first to identify the mycorrhizal fungi that associate with tree seedlings on lowland heathlands and it is one of the first biome-level mycorrhizal studies of secondary plant succession. The data presented provide the stepping-stones required for future ecologically-relevant modelling and experimentation aimed at understanding mycorrhizal invasions.

Diseases in natural ecosystems are often assumed to be less severe than those observed in domestic cropping systems due to the extensive biodiversity exhibited in wild vegetation communities. In Australia, it is this natural biodiversity that is now under threat from Phytophthora cinnamomi. The soilborne Oomycete causes severe decline of native vegetation communities in south-western Victoria, Australia, disrupting the ecological balance of native forest and heathland communities. While the effect of disease caused by P. cinnamomi on native vegetation communities in Victoria has been extensively investigated, little work has focused on the Anglesea healthlands in south-western Victoria. Nothing is known about the population structure of P. cinnamomi at Anglesea. This project was divided into two main components to investigate fundamental issues affecting the management of P. cinnamomi in the Anglesea heathlands. The first component examined the phenotypic characteristics of P. cinnamomi isolates sampled from the population at Anglesea, and compared these with isolates from other regions in Victoria, and also from Western Australia. The second component of the project investigated the effect of the fungicide phosphonate on the host response following infection by P. cinnamomi. Following soil sampling in the Anglesea heathlands, a collection of P, cinnamomi isolates was established. Morphological and physiological traits of each isolate were examined. All isolates were found to be of the A2 mating type. Variation was demonstrated among isolates in the following characteristics: radial growth rate on various nutrient media, sporangial production, and sporangial dimensions. Oogonial dimensions did not differ significantly between isolates. Morphological and physiological variation was rarely dependant on isolate origin. To examine the genetic diversity among isolates and to determine whether phenotypic variation observed was genetically based, Random Amplified Polymorphic DNA (RAPD) analyses were conducted. No significant variation was observed among isolates based on an analysis of molecular variance (AMQVA). The results are discussed in relation to population biology, and the effect of genetic variation on population structure and population dynamics. X australis, an arborescent monocotyledon indigenous to Australia, is highly susceptible to infection by P. cinnamomi. It forms an important component of the heathland vegetation community, providing habitat for native flora and fauna, A cell suspension culture system was developed to investigate the effect of the fungicide phosphonate on the host-pathogen interaction between X. australis and P. cinnamomi. This allowed the interaction between the host and the pathogen to be examined at a cellular level. Subsequently, histological studies using X. australis seedlings were undertaken to support the cellular study. Observations in the cell culture system correlated well with those in the plant. The anatomical structure of X australis roots was examined to assist in the interpretation of results of histopathological studies. The infection of single cells and roots of X. australis, and the effect of phosphonate on the interaction are described. Phosphonate application prior to inoculation with P. cinnamomi reduced the infection of cells in culture and of cells in planta. In particular, phosphonate was found to stimulate the production of phenolic material in roots of X australis seedlings and in cells in suspension cultures. In phosphonate-treated roots of X australis seedlings, the deposition of electron dense material, possibly lignin or cellulose, was observed following infection with P. cinnamomi. It is proposed that this is a significant consequence of the stimulation of plant defence pathways by the fungicide. Results of the study are discussed in terms of the implications of the findings on management of the Anglesea heathlands in Victoria, taking into account variation in pathogen morphology, pathogenicity and genotype. The mode of action of phosphonate in the plant is discussed in relation to plant physiology and biochemistry.

Terrestrial invertebrates were surveyed from south coast heathland environments, Gull Rock and Waychinicup National Park. These study sites chosen from within these two regions consist of both healthy and Phytophthora cinnamomi infected vegetation. Phosphite was being aerially applied to parts of these sites as a preventative treatment for the further spread of Phytophthora dieback disease into healthy areas. The experiment aimed to sample terrestrial invertebrate communities using pitfall traps and a foliage beating technique in Phytophthora dieback affected areas and healthy areas and also before and after phosphite application to assess any potential non-target impacts. Invertebrates were identified and analaysed at ordinal level classification and Coleoptera (beetles) were sorted to morphospecies to assess impacts at a finer taxonomic level. Shannon-Wiener Index of Diversity, Sorenses Index of Similarity, Multi-dimesional Scaling, Multi-variate ANOVA and Univariate ANOV A were all used to decide whether there were any impacts of Phytophthora dieback and Phosphite Application of the invertebrates collected. Analysis revealed strong seasonal effects within data but no trends eluding to impact of Phytophthora dieback or Phosphite application.
