— Are parks effective in forest conservation? This study examines data from 163 forests in 13 countries to determine the necessity of legally established protected areas for forest conservation and alternative conditions and institutions that may conserve forests. The results show no statistically significant differences in forest conditions between legally protected forests and forests governe...

In contrast to a few isolated forests in northern Mexico, most forests in the western Untied States have been significantly modified by fire suppression, harvesting, and livestock grazing. This has increased their fire hazards and many are in need of restoration. Understanding reference conditions is challenging because we have few intact forests functioning under the continuing influence of cl...

gauge instrument or prism was introduced, which significantly expedited the process. There was no national forest resource information in China during 1963–1972. The first NFI was performed during 1973–1976, in which a stratified systematic sampling technique was used to locate NFI sample plots. Each province, autonomous region, or municipal city designed one or more sampling populations accord...

hara biosphere reserve in southern hormozgan province with 85686 hectares areas is located between bandar khamir and queshm island. this area can be considered as the most spectacular regions of iran for a unique coastal seascape. mangrove forests and amazing biodiversity make this region as the most significant ecotourism areas throughout the country. this research attempts to determine recrea...

Uncertainties remain in the potential of forest plantations to sequestrate carbon (C). We synthesized 86 experimental studies with paired-site design, using a meta-analysis approach, to quantify the differences in ecosystem C pools between plantations and their corresponding adjacent primary and secondary forests (natural forests). Totaled ecosystem C stock in plant and soil pools was 284 Mg C ...

Private forests harbor considerable biodiversity, however, they are under greater threat than reserved areas, particularly from urbanization, agriculture, and intense exploitation for timber and fuel wood. The extent to which they may act as habitats for biodiversity and how level of protection impacts trends in biodiversity and forest structure over time remain underresearched. We contribute t...

Tropical forests are major contributors to the terrestrial global carbon pool, but this pool is being reduced via deforestation and forest degradation. Relatively few studies have assessed carbon storage in degraded tropical forests. We sampled 37,000 m(2) of intact rainforest, degraded rainforest and sclerophyll forest across the greater Wet Tropics bioregion of northeast Australia. We compare...
