Are Scat Surveys a Reliable Method for Assessing Distribution and Population Status of Pine Martens?

摘要: Systematic searches for marten feces or’ scats’ have been used since 1980 assessing the status of protected populations pine martens (Martes martes) in Britain. Previous surveys using scats relied on unsubstantiated assumptions that typically defecate along roads and trails, inhabit primarily woodland habitats, from can reliably be distinguished those other carnivores. Results scat drawn conflicting conclusions about population status, which has lead to disagreement conservation action, doubts reliability validity associated with technique. We reviewed recent history survey programs Great examined made different considered these critically. The technique several limitations, is likely least reliable where are low distribution uneven. New DNA testing approaches revealed inaccuracy identification field. recommend should conducted only when genetic verification available confirm identity.
