Journal ArticleDOI
TL;DR: In this paper, a basal area increment model is developed for all the main forest species in Austria: spruce (Picea abies), fir (Abies alba), larch (Larix decidua), Scots pine (Pinus sylvestris), black pine (Pus nigra), stone pine (pinus cembra), beech (Fagus silvatica), oak (Quercus robur, Quercus petraea and Quercius cerris), and for all other broadleaf species combined.

Journal ArticleDOI
TL;DR: In this paper, the authors compared the damage in unplanned and planned logging operations associated with each of five logging phases: (1) tree felling, (2) machine maneuvering to attach felled boles to chokers, (3) skidding boles, (4) constructing log landings, and (5) constructing logging roads.

333 citations


Journal ArticleDOI
TL;DR: Two modelling techniques are examined: Generalised Linear Modelled (GLM) and Generalised Additive Modelling (GAM).

Journal ArticleDOI
Philip M. Fearnside1
TL;DR: In this article, a Markov matrix of annual transition probabilities was constructed to estimate landscape composition in 1990 and to project future changes, assuming behavior of farmers and ranchers remains unchanged.

Journal ArticleDOI
TL;DR: Investigation results show that ungulates play a very important part on the structure and dynamics of the regeneration of this forest, and competition, while still intensive, is no longer important.

258 citations


Journal ArticleDOI
TL;DR: In this paper, the potential impact of ungulates on forest regeneration, man-made disturbances of the ungulate-vegetation system, and silvicultural measures to avoid game damage are discussed.

Journal ArticleDOI
TL;DR: In this article, three levels of logging-residue harvesting had been applied: (i) conventional stem harvest (residues left on site), (ii) harvesting all above-ground tree parts except needles, and (iii) aboveground whole-tree harvesting (no residues remaining).

Journal ArticleDOI
TL;DR: In this article, a number of nutritional and edaphic parameters across a deposition gradient in the San Bernardino Mountains (SBM) support the hypothesis that the mixed conifer forest in the western end of the range is also saturated.

Journal ArticleDOI
TL;DR: The role of regeneration in offsetting emissions from deforestation in the Brazilian Legal Amazon has sometimes been exaggerated as discussed by the authors, where cattle pasture (rather than shifting cultivation) usually replaces forest in Brazilian Amazonia.

214 citations


Journal ArticleDOI
TL;DR: In this article, the effects of harvest intensity on exchangeable cations (1 M NH 4 Cl extracts) were examined in four coniferous forest soils in Sweden, 15-16 years after clear-felling.

Journal ArticleDOI
TL;DR: Lack of standard diameter measurement criteria, and small and potentially unrepresentative plot locations as two problems in assessing the role of very large trees in other neotropical forests are identified.

Journal ArticleDOI
TL;DR: A large data set on the biophysical characteristics of north-eastern New South Wales, a region of 7.6 × 106 ha, was analysed to measure the level of protection of the region's forests from extractive uses as discussed by the authors.

Journal ArticleDOI
TL;DR: The effects of seasonality, canopy openness and root competition were studied on seedling development of four canopy tree species in secondary dry forest in the Guanacaste region of Colombia.

Journal ArticleDOI
TL;DR: In this article, high rates of nitrogen (N) deposition were first postulated as a cause of N saturation (i.e., the availability of NH4-N and NO3-N in excess of total combined plant and microbial nutritional demand) and spruce mortality during the 1980s.

Journal ArticleDOI
TL;DR: In this paper, the volume of timber removed, the date of logging, date of arboricide treatment and volume of applied in most compartments in the Budongo Forest Reserve was investigated.

Journal ArticleDOI
TL;DR: In this article, the effects of forest management and soil acidity on herb layer vegetation were studied after 10 years on 190 permanent plots in south Swedish beech (Fagus sylvatica) and oak (Quercus robur) forests.

Journal ArticleDOI
TL;DR: In this paper, a crown ratio model for individual trees is developed for all major tree species in Austria using nonlinear regression with a logistic function and the argument of the logistic was a linear combination of tree size characteristics, stand density measures, and topographic site factors.

Journal ArticleDOI
TL;DR: In this paper, the authors group the important ecological concepts incorporated into density management diagrams into three broad categories: (1) the generality of allometric relationships; (2) the nature of size-density relationships; and (3) the ability of relative density indices to characterize stand development.

Journal ArticleDOI
TL;DR: Results from the present study show that once the dormancy in leguminous species with hard seed coats is broken, the seeds germinate in wide ranges of temperature.

Journal ArticleDOI
TL;DR: Browsing and bark stripping are always highly selective, whilst a difference between red and roe deer was found in relation to fraying damage, and the lethality of damage resulting from browsing is nil with low densities of ungulates, whereas it increases rapidly with good correlation when ungulate densities are high.

Journal ArticleDOI
TL;DR: The effect of logging and slash burning on areal distribution of soil profile disturbance, fire intensity class and physical and hydrological properties of the 0–100 mm surface soil in the Victorian Central Highlands, southeastern Australia is quantified.

Journal ArticleDOI
TL;DR: Light treatments significantly affected both seedling survival and growth and soil fertility affected seedling growth, but not survival, mainly in non-limiting light conditions where stem and leaf dry weight and leaf area were higher in O than in M soil.

Journal ArticleDOI
TL;DR: Large responses may be obtained frequently by inoculation with mycorrhizal fungi selected for high efficiency or by management to increase populations of indigenous fungi where these are highly effective but low in number.

Journal ArticleDOI
TL;DR: In this article, the authors present a synthesis with which to draw together into fuller context the various contributions of this special issue of Forest Ecology and Management on Ungulates in Temperate Forest Ecosystems.

Journal ArticleDOI

TL;DR: The decline in cover of the main food plant species (bramble Rubus fruticosus), was much greater than the decline in deer density, implying that the deer were forced to change their diet and perhaps also their patterns of habitat selection in response to the change in habitat structure.

Journal ArticleDOI
TL;DR: The richness of eucalypt communities, the rarity of many arthropod species, and the association of the richest communities with temperate, moist forests on the most productive soils suggests that eucallypt forest biodiversity will be sensitive to changes in forest structure, floristic composition, and changed levels of productivity associated with logging and broad area fuel reduction fires.

Journal ArticleDOI
TL;DR: In this article, the authors compared the structure and dynamics of natural and managed forests and identified the key elements related to biodiversity in Danish forests, including woody debris, forest heterogeneity, successional continuity and water.

Journal ArticleDOI
TL;DR: The root systems of these two poplar genotypes apparently contain sufficient carbon and nitrogen reserves to fuel a spring flush of fine-root growth, even though the tops have been severed during the dormant season.

Journal ArticleDOI
TL;DR: In this paper, the authors identified three major types of population structures: a decrease in number of individuals with size, the typically inverse J-shaped curve indicating sufficient regeneration; an increase in number with size indicating an absent or sparse regeneration; variable, consisting of strongly fluctuating patterns, in most cases many small individuals, no intermediate and many large ones.

Journal ArticleDOI
TL;DR: SLA strongly varied within trees, but not between trees: needle biomass was strongly linearly related to needle area and sapwood area was linearly correlated with sapwood cross-sectional area at breast height.
