the evaluation of ecological characteristics of wildlife species has fundamental role in species management, because taking a decision for proper method of management is only possible by characterizing of ecological requirements of a species. in this study, suitable habitat of middle spotted woodpecker was investigated in golestan national park. presence and absence of birds and environmental v...
This paper uses household level data to examine the ecological and political factors and household characteristics associated with small farmer land use change and forest clearing between 1993 and 1998. The research site is a settlement frontier within a protected area in northern Guatemala. The great expanse of accessible, open land of the Sierra de Lacandón National Park (SLNP) has been a mag...
I estimated habitat-specific population densities for a population of Bornean white-bearded gibbons Hylobates albibarbis inhabiting seven distinct forest types at Gunung Palung National Park, West Kalimantan, Indonesia. Population densities in montane forests (0.44 individuals/km2) were almost ten times lower than those in the next best habitat (upland granite forest; 4.2 individuals/km2) and f...

I examined the lingering effects of past timber management practices on the vegetation structure and bird community of Kibale National Park, Uganda. I compared four forest treatments: unlogged native forest (UL), two that were selectively logged at low (LL) and high (HL) intensities in the 1960s, and a conifer plantation (PL). Forest-dependent birds were best represented at UL. LL was similar t...
1. In sub-Saharan Africa, tropical forests are increasingly threatened by accelerating rates of forest conversion and degradation. In East Africa, the larger tracts of intact rainforest lie largely in protected areas surrounded by converted landscape. Thus, there is critical need to understand the functional links between large-scale land use and changes in river conditions, and the implication...
The lack of scientific baseline information hinders appropriate design and management of protected areas. To illustrate the value of science to management, we consider five scenarios for the 202.0 km² Puerto Princesa Subterranean River National Park, Philippines: (1) closure to human activities, (2) and (3) two levels of increase in unplanned human activities, (4) creation of a forest corridor ...
The Nagagamisis Central Plateau (located in Northern Ontario, Canada) is an area of distinct natural and cultural significance. The importance of this land was officially recognized in 1957 through the establishment of the Nagagamisis Provincial Park Reserve. The park has experienced significant expansion since its inception and is currently under development as one of Ontario Parks ‘Signature ...
Even after 30 years of strict de jure protection, today's de facto extraction of products from Nepal's Royal Chitwan National Park (RCNP) and their great economic importance to local households suggests that this reality should be explicitly internalised in managing this world heritage park. Several studies have quantified local people's use of protected areas and estimated the value of such ar...
