We compile over 270 wildlife counts of Kenya's wildlife populations conducted over the last 30 years to compare trends in national parks and reserves with adjacent ecosystems and country-wide trends. The study shows the importance of discriminating human-induced changes from natural population oscillations related to rainfall and ecological factors. National park and reserve populations have de...

State parks are typically established to preserve natural or native habitats for wildlife while simultaneously providing recreational experiences for humans. However, because of their proximity to urban centers, the level of human visitation associated with state parks may be highly variable. Little information has been published regarding the eff ect of human visitation levels on wildlife esca...
Conservation policies influence both the amount of habitat loss and patterns of habitat fragmentation. This paper develops a “microlandscapes” approach that combines fragmentation measures with quasi-experimental evaluation methods in order to assess the effects of policy on habitat fragmentation. As an application, the paper estimates whether and to what extent wildlife sanctuaries and nationa...
With increasing public interest in wildlife watching, there is a need to develop methods to better inform management of quality viewing opportunities. In this study, normative methods using indicators and standards of quality are applied at two diverse parks/ protected areas: a popular national park in Alaska and a lesser known wildlife refuge in New Hampshire. Three potential indicators of qua...
Peste des petits ruminants virus (PPRV) is causing infectious disease with high morbidity and mortality rate in domestic and wild small ruminants of Pakistan with valuable economical losses.

However, it is also a source of mortal danger to its practitioners, to habituated animals, as well as to hapless third parties. Attraction or positive habituation, in which wildlife seeks out the presenc...
