Protected areas remain a cornerstone for global conservation. However, their effectiveness at halting biodiversity decline is not fully understood. Studies of protected area benefits have largely focused on measuring their impact on halting deforestation and have neglected to measure the impacts of protected areas on other threats. Evaluations that measure the impact of protected area managemen...

Conflicts between resource-dependent people and protected area managers abound in many developing countries. From the rural people's perspective, protected areas may contain valuable or necessary natural resources that are worth the effort, and risk of capture, to extract. From the protected area manager's perspective, the rural people's extraction of resources causes environmental degradation ...

Distribution modelling is important for assessing threats and conservation status of species and for planning conservation programs. We studied the distribution of suitable habitats of Asiatic cheetah (Acinonyx jubatus venaticus), Persian leopard (Panthera pardus saxicolor) and brown bear (Ursus arctos) in Isfahan province within and outside the protected areas. Suitable habitats of the three s...

In order to investigate the effect of conservation on vegetation and biodiversity, two areas were studied. The main objectives of this study were to investigate the effect of conservation on biodiversity indicators. This study was conducted in two protected and unprotected areas with an area of ​​90 hectares. In order to harvest vegetation and biodiversity, systematic sampling method was used w...

Among the greatest challenges facing the conservation of plants and animal species in protected areas are threats from a rapidly changing climate. An altered climate creates both challenges and opportunities for improving the management of protected areas in networks. Increasingly, quantitative tools like species distribution modeling are used to assess the performance of protected areas and pr...

Protected areas are effective at stopping biodiversity loss, but their placement is constrained by the needs of people. Consequently protected areas are often biased toward areas that are unattractive for other human uses. Current reporting metrics that emphasise the total area protected do not account for this bias. To address this problem we propose that the distribution of protected areas be...
