The moist temperate Himalayas, as one of the major ecological zone of Pakistan, deserve specific attention to the conservation of environment and the sustainable development of natural resources. During the last hundred years, the area has been subjected to major structural changes leading to a decrease of about fifty per cent of the potential forest area. The decrease in forest cover, combined...

Abstract The systematic treatment of Eupatorieae tribe (Asteraceae) in the Caparaó National Park, Espírito Santo, Minas Gerais, Brazil, was carried out. Identification key, descriptions, taxonomic comments, flowering and fruiting data, illustrations conservation status were provided for species. In total, 35 species from 16 genera 11 subtribes surveyed, highlighting great richness this forest f...

Comparisons of recent and historic population demographic studies of eastern hellbenders Cryptobranchus alleganiensis alleganiensis have identified significant population declines and extirpations associated with habitat degradation, poor water quality and disease, leading to nomination as a candidate for listing under the Endangered Species Act. However, populations in the southern Appalachian...

Research on the role of local institutions in confl ict management is still limited. This study highlights various inter-settlement confl icts over the issue of unclear resource boundaries in Danau Sentarum National Park, Indonesia. The park is home to two major ethnic groups (Dayak Iban and Malay) whose livelihoods are highly dependent on fi sh and forest resources available in the park area. ...

Permanent plots in indigenous forests administered by the Department of Conservation's West Coast Conservancy in the National Vegetation Survey (NVS) database were analysed to show which forest types were adequately sampled according to identifiable forest types, and within each type, in space and in time. From 404 permanent forest plots considered in analysis, eight forest types were determine...

Mountain gorillas (Gorilla beringei beringei) are critically endangered primates surviving in two isolated populations in protected areas within the Virunga Massif of Rwanda, Uganda, the Democratic Republic of Congo, and in Bwindi Impenetrable National Park in Uganda. Mountain gorillas face intense ecologic pressures due to their proximity to humans. Human communities outside the national parks...

Visitor's access to understorey vegetation in park forest stands results in the impoverishment of plant species composition and a reduction in habitat quality. The phenomenon of biotic homogenisation is typical in urban landscapes, but it can proceed differently depending on the scale, a detail that has not been observed in previous studies. This research was carried out in seven Warsaw parks (...

Forest biomass stock and spatial distribution are still unknown parameters for many regions of the world. Today’s information is largely based on ground measurements on a plot basis without remote regions coverage. Thus, a method capable of quantifying biomass by means of Remote Sensing could help to reduce these uncertainties and contribute to a better understanding of the carbon cycle (Hought...

this study aims at assessing the impact of land use change (from forest areas to forest parks) on some silvicultural characteristics of stands under recreational land use in boloran natural forest park, kuhdasht. for this purpose, three zones including non-recreation, extensive recreation and intensive recreation regions were chosen. in each zone 30 sample plots in a systematic random design (1...
