摘要: Abstract The endangered brown bear (Ursus arctos) population in Greece is urgent need of effective protection and management; that management should be based on information both reliable quickly attained. After observing bears marking rubbing power poles, we initiated a study to collect this behavior develop an method for documenting presence Greece. Thirty-nine poles the main area were fitted with barbed wire inspected monthly year. experience gained was used survey 3 additional areas, covering representative sample species distribution country. Power pole-related behaviors associated mud smears, hair deposits, bite claw marks (hereafter referred as marks). Tracks scats also have been document Greece, but fewer these found all areas surveyed. Deterioration rate slower than t...
