A Conservation Scenario for the Clouded salamander, Hynobius nebulosus Using MPVA

Abstract

Some scenarios were compared to evaluate the effects of land management on the extinction risk of the clouded salamander, Hynobius nebulousus using meta-population vulnerability analysis, MPVA. The study site was 200ha hill in which strips of paddy field had been cultivated on small valleys, and most of those were abandoned 25 year ago. The results of computer simulation suggested that a small reserve could not compensate land development of whole area, the extinction risk increased even if the development was one third of the whole area, isolated habitat patches would not be recolonized even if the land was not developed, and abandonment of cultivating paddy field raised the extinction risk more than partial development did.
