Journal ArticleDOI
TL;DR: In this article, a general review of the effects of fire on belowground systems with emphasis placed on the changes in physical, biogeochemical and biological properties of soils and the resulting consequences these changes have for ecosystem sustainability.

1,485 citations

474 citations


Journal ArticleDOI
TL;DR: In this paper, the above-ground dry biomass of living trees including palms was estimated in 65 1 ha plots spanning a 1000 km 2 landscape in central Amazonia, where the study area was located on heavily weathered, nutrient-poor soils that are widespread in the Amazon region.

399 citations


Journal ArticleDOI
TL;DR: Individual tree mortality models were developed for the six major forest species of Austria and found the hyperbolic transformation of diameter (D−1) to be highly significant in predicting the high mortality rates for small diameter trees and decreasing mortality Rates for larger diameters, while basal-area-in-larger-trees (BAL) was found to be a highly significant predictor of mortality rate for all species.

352 citations


Journal ArticleDOI
TL;DR: In this article, a map of the biomass density and pools, at the county scale of resolution, of all forests of the eastern US using new approaches for converting inventoried wood volume to estimates of above and belowground biomass.

348 citations


Journal ArticleDOI
TL;DR: In this paper, two yield optimisation experiments in young stands of Norway spruce in northern and south-eastern Sweden are presented after 10 and 9 years' treatment, respectively.

347 citations


Journal ArticleDOI
TL;DR: In this paper, species-specific and mixed-species regressions for estimating total above-ground dry weight (DW) were developed using eight abundant secondary forest tree species in the central Amazon.

344 citations


Journal ArticleDOI
TL;DR: A nest web is constructed for the cavity-nesting community in north-central British Columbia to test how nest web structure shifts in response to different forest-cutting regimes, and whether changes in species richness and abundance can be ameliorated with selective harvesting.

335 citations


Journal ArticleDOI
TL;DR: Tree growth, biomass productivity, litterfall mass and nutrient content, changes in soil chemical properties and understory forest succession were evaluated over a 8.5-year period in single- and mixed-species plantations of Casuarina equisetifolia and Leucaena leucocephala.

315 citations


Journal ArticleDOI
TL;DR: The validity and use of the indicator species concept, the design of logging impact studies, the need for long-term monitoring programs and how they might be designed, and trade-offs between conservation strategies and economic costs are topics critical to the future direction of biological conservation in managed forests.

Journal ArticleDOI
TL;DR: In Nantahala National Forest, North Carolina, the US Forest Service conducted a prescribed burn along with a southfacing slope of the southern Appalachian watershed in 1995 to create a mosaic of fire intensities to restore a degraded pine/hardwood community and stimulate forage production and promote oak regeneration along a hillslope gradient as mentioned in this paper.

Journal ArticleDOI
J.W Humphrey1, C Hawes1, A. J. Peace1, R. Ferris-Kaan1, M.R Jukes1 
TL;DR: In this article, a methodological approach to the identification of biodiversity indicators in commercial forest stands is illustrated by analysis of the relationships between syrphid and carabid community composition and diversity, and stand structure and field layer vegetation.

Journal ArticleDOI
TL;DR: It is suggested that species composition and their contribution toward litter becomes important in overall community or site litter production as observed in sites II and III, when compared to sites I and IV.

Journal ArticleDOI
TL;DR: A review of the state of the art of decision support systems related to implementing ecosystem management can be found in this article, where a conceptual model of the context in which ecosystem management is expected to function is presented and a candidate for an operational ecosystem management process is described.

Journal ArticleDOI
TL;DR: The impact of habitat quality and site history on the recolonization potential of ancient-forest plant species on abandoned farmland was studied in the forest of Ename, Flanders, Belgium as discussed by the authors.

Journal ArticleDOI
TL;DR: In this article, a large-scale field trial of short-rotation coppice with willow and poplar has been studied since the mid-1980s in the UK.

Journal ArticleDOI
TL;DR: Although possibilities of matching forestry with maintenance of taiga biota through development of harvesting methods that mimic natural disturbance seem reasonably good, there is an urgent need to establish criteria for the assessment of the success or failure of such methods.

Journal ArticleDOI
TL;DR: Effective management for biodiversity (generally species richness) entails a frank commitment to maintain biodiversity as an end, not as a means.

Journal ArticleDOI
TL;DR: In this article, the authors tested the hypothesis that a shelterwood harvest of an oak-dominated stand, followed several years later by a prescribed fire, would adequately regenerate the stand.

Journal ArticleDOI
TL;DR: The purpose of this paper is to outline the steps and rationale of a monitoring approach, using soil-based indicators as an example, to assess stand-level sustainability of intensively managed forests.

Journal ArticleDOI
TL;DR: In this paper, the effects of short-rotation forest afforestation on the top soil of three plantations on former arable soils in southern, central and northern Germany were investigated.

Journal ArticleDOI
TL;DR: Rec reconstructed the historical stand structure and spatial patterning of fire-maintained ponderosa pine forests in the Eastern Cascades of Washington to develop and design silvicultural prescriptions to restore historical structure and composition found that significant clumping at fine scales (0–15 m) existed historically.

Journal ArticleDOI
TL;DR: A biomass estimation procedure is defined as a planned chain of elements, integrated to comply with a specific aim as discussed by the authors, which can be modified according to the predefined aim and object of estimation.

Journal ArticleDOI
TL;DR: In this article, Dendrochronological analyses indicate that Pterocarpus angolensis produces anatomically distinctive annual growth rings in the indigenous forests of western Zimbabwe.

Journal ArticleDOI
TL;DR: The balsam poplar Muhle Larsen proved to be the most interesting species tested and seems to be well supplied with nutrients for optimal growth and does not need any fertilization or pesticide treatment for at least 10–15 years.

Journal ArticleDOI
TL;DR: The species spectrum of bark beetles and their enemies could be broadened by promoting a deciduous mixture and improving the supply of dead trees in managed forests, which would also be beneficial to the conservation of species diversity in the managed forest landscape.

Journal ArticleDOI
TL;DR: Salamander relative abundance was significantly lower after harvest on the group selection, shelterwoods, leave-tree, clearcut, and clearcut treatments, while there was no significant difference in relative abundance on the control or understory removal treatments.

Journal ArticleDOI
TL;DR: In this paper, the authors proposed a method to measure the direction of change in soil fertility by using the fluxes entering and leaving a selected compartment and the budget provided a realistic picture of the trend of change.

Journal ArticleDOI
TL;DR: In this article, the authors compared 14 different biomass equations taken from previous studies and established an appropriate mathematical formula to estimate the vegetation weight of a particular region in the Amazon forest, using a 0.2-ha area of Terra firme forest.

Journal ArticleDOI
TL;DR: In this article, a review summarizes information from studies of forest fertilization around the world, and evaluates the responses of streamwater chemistry, with a few studies reporting concentrations as high as 10−25 (mg N)/l as nitrate.
