Otters, their habitat and conservation in Northeast Greece

摘要: Abstract In 1983, in northeastern Greece, 1000 m of waterway at 52 sites were searched for signs otters Lutra lutra L. while the habitat was assessed its suitability to otters. The otter scarce west study area (Axios and Aliakmon catchments) most widespread east (Nestos catchment neighbouring rivers). Nevertheless, a decline had occurred this eastern since 1981, though it confined lowlands. riparian vegetation is described. Overall Nestos best cover, upland rivers greater cover than lowland or canals. Sprainting intensity by correlated with amount cover. Rubus especially important on rivers, Salix Phragmites apparent internationally population some concern recommendations conservation are presented.
