TL;DR: This paper discusses silvicultural approaches that promote or maintain structural attributes of old-growth forests at the forest stand level in current old- Growth forests managed for timber production to retain structural elements and regrowth and secondary forests to restore old- growth structural attributes.

TL;DR: In this paper, allometric equations are presented for Dipterocarp forests based on the genera of commercial species and mixed species, and an equation of a mix of these genera represents commercial species.

TL;DR: In this paper, the authors present estimated ranges in carbon (C) sequestration per kg nitrogen (N) addition in above-ground biomass and in soil organic matter for forests and heathlands, based on: (i) empirical relations between spatial patterns of carbon uptake and influencing environmental factors including nitrogen deposition (forests only), (ii) 15N field experiments, (iii) long-term low-dose N fertilizer experiments and (iv) results from ecosystem models.

TL;DR: In this paper, the past, present, and future use of the concept of historical range and variability (HRV) in land management is examined along with a discussion on the value of HRV in a changing world with rapid climate warming, exotic species invasions, and increased land development.

TL;DR: In this article, a review of the current knowledge of the ecology and management implications associated to tropical dry forest succession is presented, focusing on the use of chronosequences, plant diversity and composition, plant phenology and remote sensing, pollination, and animal-plant interactions.

TL;DR: Allometric equations developed and applied to forest inventory data to estimate biomass and carbon stocks for temperate species and forests of Durango and Chihuahua and for tropical dry forests of Sinaloa, Mexico predict a mean (confidence intervals) of 130 Mg ha−1 for total tree and total aboveground biomass.

TL;DR: In this article, the authors explore the impact of land use change in terms of provision of ecosystem services by following two approaches, one very detailed (focused on hydrological services - water quality) and another one with a broader perspective (at a large scale and considering the ecosystem service value (ESV) of several ecosystems and their ecosystem services at the same time).

TL;DR: In this article, a bioclimate model predicting the presence or absence of aspen, Populus tremuloides, in western USA from climate variables was developed by using the Random Forests classification tree on Forest Inventory data from about 118,000 permanent sample plots.

TL;DR: In this article, the authors analyzed changes in forest cover and landscape configuration over an area of 600 by 100 km located in NW Argentina (Tucuman and Salta provinces) in four periods between 1972 and 2007.

TL;DR: In this paper, a 52-year fire history from a eucalypt forest region in south-western Australia was analyzed to quantify the impact of prescribed burning on the incidence, extent and size distribution of wildfires.

TL;DR: In this paper, the authors compare current geographic distributions of tree seedlings (trees with a diameter at breast height ≤ 2.5 cm) with biomass (tree with aiameter at breast length > 2 cm) for sets of northern, southern, and general tree species in the eastern United States using a spatially balanced, region-wide forest inventory.

TL;DR: In this paper, the influences of elevation and aspect on soil variables were measured in the early (1998) and late summer (1994) of the H.J. Andrews Experimental Forest (HJA) in the Oregon Cascade Mountains.

TL;DR: In this article, a review of interactions between forests and snow avalanches in mountain ecosystems and discusses how avalanche disturbance regimes and associated management may change in the future, and further research is needed to address uncertainties in the current knowledge of avalanche disturbances, the likely interacting effects of changes in climate and land-use on avalanche regimes, potential future shifts of avalanche prone areas, and the impacts of avalanches.

TL;DR: In this paper, the influence of environmental factors on forest growth was examined using data from intensive monitoring plots spread over Europe for a five-year period, and the authors found a positive relationship between higher than normal volume increment and nitrogen deposition.

TL;DR: The density of live lodgepole pine trees in mountain pine beetle-affected stands was higher than Engelmann spruce, subalpine fir, and aspen, in diameter classes comprised of trees from 2.5 cm to 30 cm in diameter, suggesting that lodge pole pine will remain as a dominant overstory tree after the bark beetle outbreak.

TL;DR: In this paper, the authors established 60 20 � 50 m plots in mature and regenerating forests in the Sector Santa Rosa (formerly known as Parque Nacional Santa Rosa) and Palo Verde National Park.

TL;DR: In this article, the authors presented a method to increase the level of detail of aboveground biomass estimates at a regional scale based on empirical relationships while materials are based on MODIS products and field measurements; the area covers from 4° south up to 12° north of the Equator with a total of 1139,012 km2 corresponding to the continental area of Colombia.

TL;DR: In this article, the authors investigated the question of whether litter terpene content can be used to estimate flammability and temperatures reached during fire and concluded that plants might influence fire intensity, by having stored terpenes in their dead leaves, in addition to having developed traits to survive fire.

TL;DR: In this paper, the authors focused on natural disturbance regimes other than fire and on interactions between different disturbance types, and found that the greatest challenges to implementation of ENDR are socioeconomic rather than ecological.

TL;DR: In this article, the authors discuss how the common forestry practice of creating clear cuts in relatively homogenous, managed forests may increase the potential impact of ungulates, and they suggest that there is much to gain if management approaches would focus at influencing foraging behaviour of animals and reduce their concentration in forest gaps, rather than purely focusing on population control.

TL;DR: The impact of different disturbances on the abundance of small mammals appears to be species-specific, but disturbance type may influence the magnitude of this effect.

TL;DR: An individual-based simulation model is constructed to predict diameter distribution and formation of hollows in oak tree populations in southeast Sweden and suggested that future studies should focus on tree mortality at different conditions.

TL;DR: In this article, the effects of fuel treatments on wildfire severity in an area of wildland-urban interface were quantitatively assessed in the Lake Tahoe Basin following the 2007 Angora Fire.

TL;DR: In this paper, the effect of forest management on streamflow in two watersheds in the Valdivian Andes (600-650 m of elevation; 39837 0S), and fish abundance as a function of forest cover in 17 watersheds located in the Coastal Range and the Central Depression (39850 0 -42830 0 S).

TL;DR: In this paper, a comprehensive dendroecological investigation of two basic and alternative hypotheses that explain the decline by either climatic influences or by SO 2 pollution as the primary factors is presented.

TL;DR: Wang et al. as discussed by the authors estimated carbon stocks and its changes in the living biomass and soil organic matter in bamboo stands in China in the past five decades based on these collated data together with the area of bamboo stands and number of bamboo culms derived from the National Forestry Inventory.

TL;DR: Logistic regression modeling found that probability of ponderosa pine mortality caused by bark beetles was positively correlated with tree density and inversely related with elevation and tree diameter, and resulting logistic models to estimate the likelihood of bark beetle attack should have wide applicability across similar ponderosa Pine forests across the Southwest.

TL;DR: In this article, the authors investigated changes in an Atlantic Rainforest region due to major biophysical and human proximate causes, including land cover and land-use changes from 1962 to 2000, including deforestation and forest regrowth, and thereby simulated future landscape trajectories to assess their possible effects on the conservation of forest species of the Ibiuna Plateau.

TL;DR: In this article, a two-dimensional fire growth and behavior model was activated, using ArcView VBA code, to generate Monte Carlo simulations of fire spread, which revealed a clear pattern of fires with high frequency areas concentrated in the northwestern part.
