For mapping, quantifying and monitoring regional and global forest health, satellite remote sensing provides fundamental data for the observation of spatial and temporal forest patterns and processes. While new remote-sensing technologies are able to detect forest data in high quality and large quantity, operational applications are still limited by deficits of in situ verification. In situ sam...
As a large carbon pool, global forest ecosystems are a critical component of the global carbon cycle. Accurate estimations of global forest aboveground biomass (AGB) can improve the understanding of global carbon dynamics and help to quantify anthropogenic carbon emissions. Light detection and ranging (LiDAR) techniques have been proven that can accurately capture both horizontal and vertical f...
Many products are harvested from the forests of the eastern United States that are nottimberbased but originate from plant materials. Over the past decade, concern has grown about the sustainability of the forest resources from which these products originate, and an associated interest in managing for these products has materialized. A content analysis of the management plans of 32 eastern nati...
this paper discusses the study of community’s preferences for biodiversity conservation management institution which may motivate them to support conservation efforts in the okwangwo division of the cross river national park, nigeria. the empirical data was generated from personal interviews and factors influencing the respondents’ choice were examined with the aid of multinomial logit mode...
Large quantities of forest products are disposed of in landfills annually. The fate of this vast pool of carbon is important since carbon sequestration and the generation of landfill gases have important implications for global warming. Published estimates of methane yields were used to estimate the amount of carbon released into the atmosphere from landfilled forest products. These calculation...
Southern forests produce multiple products and services including timber, wildlife habitat, species bioand genetic diversity, water quality and control, waste remediation, recreation, and carbon sequestration. All of these benefits must be produced in a sustainable manner to meet today’s societal needs without compromising future needs. A forest site is productive to the extent that it provides...
