Protected areas' chief conservation objectives are to include species within their boundaries and protect them from negative external pressures. Many protected areas are not achieving these goals, perhaps in part due to land development inside and outside protected areas. We conducted spatial analyses to evaluate the ability of Canadian protected areas to mitigate the effects of nearby land dev...
Spatial patterns are suitable tools for optimal management in many forested areas. In this research, the effect of conservation on spatial pattern of dominant trees has been studied. To achieving this purpose, protected and non- protected forests were selected in Masal region of Guilan province as the study area. Sampling methods including fixed- area plots and distance methods, such as T- squa...
in recent decades, necessity to protect environment has been a serious concern for all people and international communities. in appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. as a resu...
This investigation is a collection of studies on the breeding birds of Dez Protected Area performed from Fe-bruary 2011 to Jun 2012. During that period, field studies were executed every other 2-4 days. 5 species of native bree-ding birds including White-eared Bulbul Pycnonotus leucotis, Common Babbler Turdoides caudatus, Collared Dove St-reptopelia decaocto, Laughing Dove Streptopelia senegale...
natural sites with spiritual values are parts of land or sea that play key role in conserving biodiversity and cultural identity. the aim of this study is prioritizing protected zones with spiritual values. in the first step for this survey, based on literature review and according to multi criteria assessment, convenient conservation criteria were compiled, then for each of criterion, indices ...
brown bear (ursus arctos) is one of the most important carnivores in iran. however, information on its habitat associations is scared. based on ecological niche factor analysis (enfa) method, a summer habitat suitability model was developed for this species in the southern part of alborz protected area. our results showed that, brown bears prefer higher altitudes and northern aspects in their p...
Protected areas (PAs) are at the forefront of conservation efforts, and yet despite considerable progress towards the global target of having 17% of the world's land area within protected areas by 2020, biodiversity continues to decline. The discrepancy between increasing PA coverage and negative biodiversity trends has resulted in renewed efforts to enhance PA effectiveness. The global conserv...
