Abstract (sommario):

The European (EU) race of Gremmeniella abietina (Lagerb.) Morelet, the causal agent of scleroderris canker of conifers, is a damaging pathogen in pine forests. In North America, this disease is found in the northeastern United States and in eastern Canada. Results from surveys conducted across Canada since 1979 are updating us on where this disease is found. In Newfoundland, only the EU race has been recorded and it is restricted to the Avalon Peninsula Contrary to earlier reports in the Maritime provinces, only one pine plantation is infected by the EU race in New Brunswick. In Ontario, a total of 171 plantations are infected and they are clustered in the central portion of the southern part of the province. The number of plantations infected by the EU race in Quebec is the highest in Canada with 749 plantations. In the four provinces, the most infected species is red pine (86% of the infected plantations), followed by two exotic species, Scots pine (9.5%) and Austrian pine (3.2%). White pine and jack pine show resistance to the disease. Key words: Brunchorstia pinea, Pinus resinosa, reforestation, Scleroderris lagerbergii

Abstract (sommario):

Afforestation programs such as the one promoted by the EU Common Agricultural Policy have spread tree plantations on former cropland. These afforestations attract generalist forest and ubiquitous species but may cause severe damage to open habitat species, especially birds of high conservation value. We investigated the effects of young (<20 yr) tree plantations dominated by pineP. halepensison bird communities inhabiting the adjacent open farmland habitat in central Spain. We hypothesize that pine plantations located at shorter distances from open fields and with larger surface would affect species richness and conservation value of bird communities. Regression models controlling for the influence of land use types around plantations revealed positive effects of higher distance to pine plantation edge on community species richness in winter, and negative effects on an index of conservation concern (SPEC) during the breeding season. However, plantation area did not have any effect on species richness or community conservation value. Our results indicate that the effects of pine afforestation on bird communities inhabiting Mediterranean cropland are diluted by heterogeneous agricultural landscapes.

Abstract (sommario):

In the early 1980s, more than 90% of mortality caused by Gremmeniella abietina, European race, was recorded in red pine (Pinus resinosa) plantations 200 km northwest of Montreal, Quebec, Canada. Surrounding jack pines (Pinus banksiana) did not appear to be affected. Consequently, foresters began to plant the affected areas with jack pine seedlings. In 1988, plots of 100 jack pines were established in three of the four selected plantations. As reference, red pine seedlings were planted in 1989 under similar conditions in the fourth plantation. Observations were carried out annually from 1989 to 1992. Mortality of red pine seedlings reached 70% in 1992 while all jack pines on the three experimental sites were free of the disease except for a tip blight, a distinctive feature allowing race identification in the field. The North American race symptoms were present at a very low incidence, but began to increase on site I in 1992. More than 10 years after planting, the jack pine trees still show resistance to the European race of G. abietina while all the red pines died.

Abstract (sommario):

Exotic pine plantations, installed mainly for timber production and carbon sequestration purposes, cover an ever-expanding area of equatorial and tropical regions; however, their economic and environmental benefits are under debate due to their potential negative effects on native plant species conservation. The native understory plant species richness and cover under pine (Pinus radiata D. Don) plantations were compared with natural grasslands in the Ecuadorian Páramo. We analyzed the vegetation in four zones: Antisana (8-year-old pines), Cajas (16-year-old pines), Tisaleo (41-year-old pines) and Cotopaxi (53-year-old pines). The total understory plant cover decreased between 29% and 90% under pine plantations in all zones. The mean species richness in the pine plantations decreased by 44% in Antisana, Cajas and Tisaleo but not in Cotopaxi. Pine plantations strongly reduced the abundance of herbaceous light-demanding species (59%), except small herbs whose cover increased under pine (17.6%). Shrub cover was also negatively affected in Tisaleo and Cotopaxi (7.4%). Pine afforestation effects on Páramo vegetation depend mainly on canopy cover which changes with age and growing conditions (altitude) and secondarily on the vegetation state at the time of planting, resulting from land use history and ecological conditions. The pine effect was therefore more pronounced in the young and dense plantations of Antisana and Cajas than in the old and open stand of Cotopaxi, whose understory vegetation was more similar to that of grasslands.

Abstract (sommario):

Abstract An inventory of 167,316 ac of 5- to 15-year-old plantations of slash pine (Pinus elliottii Engelm.) or loblolly pine (P. taeda L.) or both in east Texas revealed that infestations (spots) of the southern pine beetle, Dendroctonus frontalis Zimm., occurred in plantations of all ages greater than 5 years. Infestation frequency ranged from 0.1 spots/1000 ac for 6-year-old plantations to 6 to 8 spots/1000 ac for 12- to 15-year-old plantations in 1985. Analyses of subsets of plantation inventories revealed that spots were more frequent in loblolly pine plantations than in slash pine plantations, and more frequent in plantations that had been prescribed-burned. An intensive study of 34 individual spots showed that spot initiation was often associated with stand disturbance but not with intraplantation variations in stand parameters. In turn, regression analyses revealed that the initial number of active trees (spot size) was directly correlated with pine basal area/ac. Rate of summer spot growth in uncontrolled infestations was most strongly correlated with number of active (brood) trees and weakly correlated with tree height and pine basal area/ac. Spots tended to grow faster in loblolly plantations than in those with slash pine. Mean spot growth rates were markedly less within young plantations than rates documented in earlier studies for natural pulpwood and sawtimber stands. A field guide for setting control priorities for beetle infestations in young plantations is provided. South. J. Appl. For. 12(3):208-214.

Abstract (sommario):

Eighteen indices were selected to evaluate soil and water conservation capacities of four different mixtures of plantations using the Ideal Point Method. Results indicate that a broadleaf plantation of robur (Lithocarpus glabra) and Chinese guger tree (Schima superba) had the best conservation capacity, a mixed broadleaf plantation of sweetgum (Liquidambar formosana), Chinese gugertree and camphor tree (Cinnamomum camphora) was ranked second. A mixed broadleaf–conifer plantation of Chinese fir (Cunninghamia lanceolata), Masson pine (Pinus massoniana) and Chinese gugertree ranked third with a mixed coniferous plantation (Chinese fir and Masson pine) fourth. Under similar climates and topographical conditions, broadleaf plantations have better soil and water conservation capacities than conifer plantations. Sensitivity analysis showed that litter amounts and soil properties are the most important indicators of soil and water conservation capacities of plantations. Suitable measures such as deep tillage should be used to improve soil aggregation in different plantations.

Abstract This research is aimed at determining the health condition and productivity of Scots pine (Pinus sylvestris L.) stands created during 1906–1908 on the initiative of Prof. V. D. Ogievsky. The scheme of silvicultural experiments included: determining the influence of different widths and directions of clear felling on the natural regeneration, testing of pine plantations of pure and mixed composition and the choice of methods for their creation. In terms of health condition, 103–105-year-old artificial pine stands are weakened and their health condition is slightly worse compared to the aged pines of natural origin. The productivity of age-old linden-pine plantations is higher than of pure pine plantations, and the stock of stem wood in plantations created by seed sowing and marketability is higher compared to the plantations created by planting seedlings.

Abstract (sommario):

Thinning and underplanting of conifer plantations to promote natural succession in southern Ontario's forests for restoration purposes was examined in a young red pine (Pinus resinosa Ait.) plantation. Eleven years after application of five thinning treatments, seedling diameter, height, and stem volume of planted white ash (Fraxinus americana L), red oak, (Quercus rubra L.), and white pine (Pinus strobus L.) were positively correlated with thinning intensity and size of canopy openings. Percent survival did not differ among thinning treatments. Based on growth and survival responses, field performance of white ash and white pine was superior to red oak. Recommendations for restoring conifer plantations to native forest types are provided.

Abstract (sommario):

Abstract After four seasons of field growth, height differences among seedlings from various seedlots of improved eastern white pine are highly significant at plantations in Connecticut, Maryland, New Hampshire, New Jersey, and New York. Survival varies from 53% to 83%, and plantation mean heights vary from 47 cm to 100 cm. Rank correlations of mean heights of seedlots at the five plantations are all positive and 8 of 10 are significant, indicating stability of performance. Two major trends show: (1) trees of a few seedlots are taller at all plantations, while those from Lake States and two Quebec seedlots grow relatively slowly wherever tested; and (2) trees of northern origin are more often taller at northern plantations, and those of central origin are taller at central plantations.

Abstract (sommario):

Midrotation data from large block plots of resistant and susceptible slash (Pinus elliottii Engelm.) and loblolly pine (Pinus taeda L.) were used in combination with the Georgia pine plantation simulator growth model to provide projected gains per hectare in volume and value generated by resistance to fusiform rust (Cronartium quercum (Berk.) Miyabe ex Shirai f.sp. fusiforme). The difference in the projected volume production between the resistant and susceptible planting stock of slash pine was larger than the difference between resistance levels in loblolly pine. The increases in projected volume and the reductions in percent infection of the resistant stock led to large differences in the value of the resistant and susceptible planting stock. At a 6% real discount rate, plantations of resistant slash pine were on average worth between 40.2 and 89.8% more than plantations of susceptible slash pine. Plantations of resistant loblolly were on average worth between 6.1 and 40.3% more than plantations of susceptible loblolly pine. However, the marginal value of rust resistance in loblolly was not significantly different from zero under the assumption that economic differences are only due to volume losses and not losses due to product degrade.

Abstract (sommario):

Accurate prediction of mortality is an important component of forest growth and yield prediction systems, yet mortality remains one of the least understood components of the system. Whole-stand and individual-tree mortality models were developed for loblolly pine plantations throughout its geographic range in the United States. The model for predicting stand mortality were developed using stand characteristics and biophysical variables. The models were constructed using two modeling approaches. In the first approach, mortality functions for directly predicting tree number reduction were developed using algebraic difference equation method. In the second approach, a two-step modeling strategy was used where a model predicting the probability of tree death occurring over a period was developed in the first step and a function that estimates the reduction in tree number was developed in the second step. Individual-tree mortality models were developed using multilevel logistic regression and survival analysis techniques. Multilevel data structure inherent in permanent sample plots data i.e. measurement occasions nested within trees (e.g., repeated measurements) and trees nested within plots, is often ignored in modeling tree mortality in forestry applications. Multilevel mixed-effects logistic regression takes into account the full hierarchical structure of the data. Multilevel mixed-effects models gave better predictions than the fixed effects model; however, the model fits and predictions were further improved by taking into account the full hierarchical structure of the data. Semiparametric proportional hazards regression was also used to develop model for individual-tree mortality. Shared frailty model, mixed model extension of Cox proportional hazards model, was used to account for unobserved heterogeneity not explained by the observed covariates in the Cox model.

Abstract (sommario):

Modeling growth dynamics of juvenile loblolly pine plantations can help to address important management decisions that have to be made in young stands. The present study addressed diameter and height prediction as well as crown development analysis as functions of independent variables such as site index, relative spacing and age for trees younger than ten years old. It was found that height prediction for trees one and two years old was a function of the products of the variables site index and age (or square root of age) and relative spacing and age (or square root of age). For trees three years old and older these were also the independent variables used to explain height prediction but in this case age (or square root of age) was another significant independent variable. In regard to diameter prediction it was observed that groundline diameter was a function of age for trees one and two years old; while this variable was also a function of site index and relative spacing for trees three, four and five years old. For trees older than five years old diameter at breast height was a function of age, site index and relative spacing. The analysis of crown development showed that for trees five years old and older variables like diameter at breast height, total height, age, site index and relative spacing were significant when crown ratio was the dependent variable. For trees younger than five years old, groundline diameter and the other same independent variables (i.e. total height, age, index and relative spacing) were again found significant when crown ratio was the dependent variable.

Abstract (sommario):

Post-planting silviculture in the exotic pine plantations of Southeast Queensland focuses on fertilisation and weed control at early plantation establishment. Early establishment silviculture in pine plantations aims to reduce the competition for light, nutrients and water in the short term, while maximising resource conversion for growth in the long term. However, silviculture can be applied in a systematic way without necessarily considering the limitations to maximum tree growth at each site. Accordingly, silvicultural treatments could be applied in a site specific manner to better reflect the limitations to tree growth at each site (e.g. nutrition and/or water), or for maximum effectiveness based on seasonal limitations (e.g. weed competition, water availability). This research aimed to investigate the effects of early establishment weed control and fertilisation practices on soil carbon (C) and nitrogen (N) cycling (as an indicator of soil fertility), tree nutrition (particularly N nutrition), growth and eco-physiological responses, in the F1 hybrid exotic pine plantations (Pinus elliottii Engelm var. elliottii x Pinus caribaea Morelet var. hondurensis (Sènècl.) W.H.G. Barett & Golfari.) in the subtropics of Southeast Queensland.

Abstract (sommario):

Loblolly pine is an important managed tree species within the southeastern United States, and better understanding spatial patterns in its productivity has potential to contribute to both modeling and management of the species. Using recently-created pine management maps specific to Virginia and empirical relationships predicting pine LAI from the Landsat satellite, we conducted a statewide analysis of temporal patterns in stand-level southern pine leaf area index (LAI) following clear-cut and planting. Here, using 28 years of Landsat time-series data for 13,140 stands that were clear-cut between 2014-2017, we examined 1) when LAI peaked over the rotation, and 2) how LAI in each stand compared to a recommended fertilization threshold of 3.5 LAI. We found that, on average, winter LAI reached a maximum of 2.02., which can be approximately doubled to give a summer LAI of 4.04, and within stand peak occurred between years 13 and 15. We also found that around 45.8% of stands achieved an LAI value higher than 3.5: a fertilization threshold recommended for managed stands in Virginia. The dataset produced by our analysis will bolster information required for modeling loblolly pines as a plant functional type in regional land simulations, and the finding that most stands are below the recommended LAI fertilization threshold will fuel further management-motivated research.
Master of Science
Management of pines in the southeastern U.S. contributes to the region's economy and carbon sequestration potential. In this study, we used Virginia forest harvest maps to identify individual patches (stands) of pine forest which had each gone through a full harvest life cycle (rotation). With unique managed pine stands identified, we used satellite imagery to estimate growth of canopy leaf area over time within each stand, using a metric called leaf area index (LAI). We identified 13,140 separate stands, each with up to 28 years of available data. We took the first full-state census of areas of managed pines in Virginia, and their leaf area development. We acquired one LAI measurement from February of each year, for each stand in Virginia. Using February LAI for each of our stands, we found that an average stand in VA has a maximum winter LAI of 2.02 (meaning an approximate maximum summer LAI of 4.04), and that stands generally reached their peak LAI after around 14 years of growth. It is recommended, in VA, that a landowner fertilize their stand in the middle of a harvest rotation if summer peak LAI is under 3.5, at stand closure. We found that at ten years of stand age, 45.8% of stands were estimated to reach above this threshold. Since this study's dataset is the most comprehensive LAI dataset for managed pines in VA, it may be used to improve management outcomes as well as understand pine productivity for land surface modeling purposes.

Abstract (sommario):

The goal of ecological restoration is to return degraded or altered ecosystems to their pre-disturbed state with respect to ecosystem structure, function, and composition. In the current study the research objective was to reestablish high levels of biodiversity on two restored pine plantations as well as restore a native pine flatwoods ecosystem. Managed, even-aged pine flatwoods are now the most extensive ecosystem in North Florida, comprising approximately 70% of the forested landscape. Slash pine trees were thinned in the experimental plots to restore the natural slash pine density of native ecosystems. In addition to the thinning treatments, experimental plots have been clear-cut and all vegetation removed from the plots. Arthropods were sampled by employing pitfall traps, sticky traps and sweep netting. This study assesseed the success of the restoration techniques employed by looking at biodiversity with a fine-resolution, taxonomically narrow approach by identifying the arthropods down to the taxonomic level of family and determining the number of morphospecies. Species were also subdivided into functional groups based upon the ecosystem services that they provide and their trophic level. Analyses revealed that arthropod species and guild diversity was not significantly affected by treatments in both 2008 and 2009. The experimental treatments were able to recover to pre-disturbance levels after two years following restoration. This indicates that these arthropod communities are fairly resilient and are able to recover fairly quickly following perturbation. Interestingly, community similarity measures revealed that although the experimental treatments were no more diverse than control plots the community species composition was fairly dissimilar between treatments, with plots becoming more dissimilar from 2008 to 2009. More long term data should reveal if these plots are proceeding along different successional trajectories in terms of community species composition and also will allow us to gain more insight into the long term effect of the treatments on biodiversity.

Abstract (sommario):

A system of equations was developed and incorporated into the PTAEDA2 loblolly pine stand simulator to provide growth projections from time of planting. Annual height growth is predicted using a two-parameter Weibull function, where distribution parameters are estimated from equations that utilize site index and age as predictor variables. Allometric equations are employed to estimate tree diameter and height-to-crown attributes. First year after planting mortality estimates are based on physiographic region and drainage class, with adjustments for bedding or discing site preparation treatments. Thereafter, a simple mortality function is used. The onset of competition is defined through a point density measure, which was conditioned to correspond with inflection points of basal area growth curves from observed data. Early silvicultural treatment response functions were also developed. These equations modify growth for shearing and piling, discing, and bedding site preparation methods, fertilization with phosphorous, nitrogen, and/or potassium, and 1-year or 2-year herbaceous weed control treatments. Differential responses due to drainage class and physiographic region are included in the response functions where necessary. Equations that account for interactions between certain treatments are used to adjust response levels where treatments have similar effects site conditions. Analyses of pre-competitive growth projections where no treatments are specified reveal that a small amount of over-prediction is present when compared with observed data. Predicted values in the post-competitive growth phase confirm that the addition of the pre-competitive growth system did not significantly affect the predictive behavior of the PTAEDA2 model. The simulated growth responses attributed to early silvicultural treatments are consistent with response levels reported in other studies.

Abstract (sommario):

The establishment of plantation forests in areas not viable for agriculture can make a significant contribution to the economy. The yield from 1 ha of plantation forest depends on the management purpose - obtaining of round wood (pulpwood, sawnlog, veneer log, tare), bioenergy and extraction of tree foliage (broadleaved and coniferous). In Latvia, based on 2019 data, plantation forests achieve 2760 ha of Scots pine, 7855 ha of Norway spruce, 7431 ha of Birch, 2123 ha of Grey alder, 1274 ha of Black alder and Populus spp. and 618 ha of Salix spp. Estimated and projected gains are calculated both as round wood over 20 to 50 years: pine - 410-to 994 thou. m3; spruce, - 335 to 2.906 thou. m3, birch - 1.040 -2.452 thou. m3. Accordingly, it is possible to obtain gross income from the whole plantation forest area in Latvia: pine-12.42-63.8 mln. EUR; spruce - 40.1 -192.3 mln. EUR; for birch - 32.2 -202.7 mln. Eur. Additionally to that, 18.6 -21.6 t ha-1 and 24.0 -37.0 t ha-1 of processed foliage can be obtained from 1 ha of pine and spruce forest plantations (40-50 years old). Alnus incana sp. (5-20 years), yielding 19.65-122.65 thou. Solid m3 and Salix spp. (3-5 years), yielding 58.71-84.97 thou. solid m3, are used for energy production, furthermore Alnus spp. wood can be used than valuable raw material for plywood production. At the same time, it is possible to capture 106-1477 thou. tonnes of CO2 equivalent. Systematic investigations of chemical composition of above mentioned Latvian plantation trees, wood and bark, have shown that incorporation of extraction treatment in existing processing schemes will allow to manufacture high value added monomeric and oligomeric products which are of great demand for substitution of synthetic ones in different economy sectors (agriculture, including means for plant protection, food industry, polymer production, pharmacy etc.). Creation of small and medium-sized enterprises in rural region in close proximity to plantations opens the opportunity for the appearance of new working places, including organization of new nurseries, plantation services, private businesses for processing of various lignocellulosic waste into new special products / semi-products / feedstock for green industrial materials and chemicals, at the same time diminishing the logistics expenses.

Abstract (sommario):

In Russia and abroad, there are large areas of land represented by sands and sand-chalk mixtures. The main task is to grow stable, long-lasting plantings on them. The authors propose to use common pine for the restoration of zonal and technogenically disturbed lands. The study of pine plantations allows us to assess their reclamation efficiency and forest suitability of the territory.

Abstract (sommario):

We have studied the state of pine phytocenoses in the city of Voronezh, along highways with different traffic intensities. A general degradation in the state of forest stands, a decrease in productivity, damage to radial growth were established. At a distance of 25-30 m from the highways, there is a decrease in the density and stock of forest stands at both sites, due to a decrease in lateral illumination, while the intensity of pollution decreases slightly. At a distance of 185-195 m from the highway at both sites, the height and growing stock reach their maximum values. Density and average diameter vary in different directions due to the presence of a concomitant recreational impact at the ―Prigorodnoye lesnichestvo‖ facility.

Abstract (sommario):

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.
