Showing papers in "Forest Ecology and Management in 2005"

TL;DR: In this paper, the authors summarize a set of simple principles important to address in fuel reduction treatments: reduction of surface fuels, increasing the height to live crown, decreasing crown density, and retaining large trees of fire resistant species.

TL;DR: In this article, the authors proposed a method to improve the soil organic carbon (SOC) stock through afforestation of agricultural soils and management of forest plantations through C sequestration, and the rate of SOC sequestration and the magnitude and quality of soil C stock depend on the complex interaction between climate, soils, tree species and management.

TL;DR: In this article, a review of the literature concerning forest and woodland structure at the scale of an individual stand is presented, where stand structure is defined in terms of structural attributes and stand structural complexity.

TL;DR: In this article, the authors summarize and synthesize the various studies that have assessed the effects of fire on forest soil microorganisms, emphasizing the mechanisms by which fire impacts these vital ecosystem engineers and suggest that more research be devoted to linking long-term plant community responses with those of the mutually dependent soil microflora.

TL;DR: In this article, the authors describe the key landscape pattern and process changes wrought by the sum of the settlement and management influences to date, and point to an uncertain future for ecosystem management.

TL;DR: The longleaf pine-grassland (Pinus palustris-Poaceae) ecosystem occupied over 30 million ha in the southeastern United States at the time of European discovery as mentioned in this paper.

TL;DR: In this paper, the impacts of organic matter removal and soil compaction are reported for the 26 oldest installations in the nation-wide network of long-term soil productivity sites, and the results show that complete removal of surface organic matter led to declines in soil C concentration to 20 cm depth and to reduced nutrient availability.

TL;DR: In this paper, the volume of dead wood in 86 beech forest reserves, covering most of the range of European beech forests, was analyzed and the mean volume was 130 m 3 /ha and the variation among reserves was high, ranging from almost nil to 550 m 3/ha.

TL;DR: In this article, the authors describe the special needs of forest managers conducting participatory sustainable forest management planning in a sometimes-polarized public context, and outline criteria for designing decision-support processes to meet these needs.

TL;DR: In this article, the authors compare computational short-cuts that have been proposed for approximating these fire behavior distributions and evaluate fire effects in a risk analysis on a common scale for the variety of values susceptible to wildland fire.

TL;DR: In this article, a replicated, stand level experiment from mixed conifer forests in the north-central Sierra Nevada that investigated how control, mechanical (crown thinning, thinning from below followed, rotary mastication), prescribed fire, and mechanical followed by prescribed fire treatments affected fuels, forest structure, potential fire behavior, and modeled tree mortality at 80th, 90th, and 97.5th percentile fire weather conditions.

TL;DR: In this article, the authors used discrete-return lidar to estimate stand structural variables, including stand height, total aboveground biomass, foliage biomass, basal area, tree density, canopy base height and canopy bulk density.

TL;DR: The benefits of using multiple criteria decision support (MCDS) methods in forest management are discussed, some recent studies indicate that, especially for behavioural reasons, it would be useful to use more than one MCDS method, or hybrid approaches, in many planning situations.

TL;DR: In this paper, the risks, hazards, and relative severity of wildland fires are presented within the ecological context of historical natural fire regimes, time, space, and process, and the authors discuss the limitations and conflicts to integrating all social, cultural, economic, health, and safety values in public and policy-forming dialogue relating to fire risk, hazard, and severity.

TL;DR: Comparisons are made for evaluating sustainable management strategies at forest management-unit level by using a C&I approach based on the Pan-European guidelines forSFM, and differences in evaluation results between AHP and ANP are discussed, as well as strengths and weaknesses of both approaches for SFM.

TL;DR: Growth of regeneration and edge trees, resulting in increased interception, shading and water extraction by roots, may have modified the gap effect seen as early as the second year after gap formation, influenced by the considerable microsite variation.

TL;DR: The use of regression and correlation analyses to determine which climate or initial litter quality factors control decay rate has led to many unwarranted and potentially misleading conclusions as discussed by the authors. But, the accumulated experimental evidence indicates that litter decomposition rates do not mediate these responses.

TL;DR: In this paper, the influence of drought and topography on recent patterns of tree mortality in old-growth mixed conifer forests in Yosemite National Park, located in the Sierra Nevada Mountains of northern California, USA, was investigated.

TL;DR: The Subjective Bray Curtis Ordination is a useful approach for evaluating different restoration techniques or identifying measures that are recovering slowly and would benefit from additional management to determine the success of a restoration project.

TL;DR: In this paper, the authors quantified prescribed fire effects at four sites in southern Ohio, from 1995 to 2002, and found that fire intensity was highest on the 2× burn units.

TL;DR: In this paper, a complete set of equations for below-and above-ground biomass of a natural Eucalyptus hybrid in Congo was constructed by fitting weighted non-linear regressions using maximum likelihood estimates.

TL;DR: In this paper, the authors report fuel consumption and changes to coarse woody debris attributes with prescribed burns ignited under different fuel moisture conditions, showing that early season burns consumed significantly less of the total dead and down organic matter than late season burns (67% versus 88%).

TL;DR: In this paper, stand data from a 35-year-old Norway spruce (Picea abies (L.) Karst) dominated stand with a deciduous admixture were used as the starting point.

TL;DR: In this article, the authors determined microbial biomass, organic carbon, total nitrogen, and microbial quotient (MBC/Corg) in soil during the secondary forest succession in north Ziwulin region in the middle of Loess Plateau, China.

TL;DR: In this paper, the authors examined visitors' preferences for forest management at five adjacent municipal recreation sites in Finland, using a spatially explicit choice experiment, and found that visitors have a strong preference for the preservation of species richness and for scenic beauty.

TL;DR: This paper proposes and combines two approaches, namely multi-criteria analysis (MCA) and participatory modeling, and describes how these two approaches can be integrated in a decision support system.

TL;DR: In this article, the existence and number of understory trees were examined by analysing the height distributions of reflected laser pulses, and the results showed that multi-layered stand structures can be recognized and quantified using quantiles of laser scanner height distribution data.

TL;DR: In this article, a list of negative consequences of plantations for biodiversity conservation was compiled from the literature, and used them to assess plantation scenarios proposed for cleared rainforest landscapes in tropical and subtropical Australia.

TL;DR: In this article, the authors investigated fine root bio-and necromass, net primary production of fine roots and its proportion of the NPP of trees, as well as turnover rate were investigated in a fertile middle-aged Norway spruce (Picea abies (L.) Karst) stand by sequential core and ingrowth core methods.

TL;DR: In this article, the authors present a methodology to predict the occurrence of windthrow after partial-cut harvesting in areas with complex stand and terrain conditions, and they developed and tested several GIS-based methods of characterizing fetch after partial harvest.
