Beech marten in quality to that of the pine marten and sable. Beech marten skins on the fur markets of the Soviet Union accounted for only 10-12% of the market presence of pine marten skins. Beech martens were caught only in the Caucasus, in the Montane part of Crimea and (in very small numbers) in the rest of Ukraine, and in the republics of Middle Asia. Because animals with more valuable pelts are rare in those areas, the beech marten is of value to hunters on the local market. Beech martens are captured with jaw traps, or, for live capture, with cage
American marten of study. Juvenile survival rates were lower, ranging from 0.26 to 0.50. In Newfoundland, annual adult survival was 0.83. Survival of juveniles from October to April was 0.76 in a protected population, but 0.51 in areas open to snaring and trapping. In western Quebec, natural mortality rates were higher in clearcut areas than in unlogged areas. American marten are vulnerable to predation from raptors and other carnivores. The threat of predation may be an important factor shaping American marten habitat preferences, a hypothesis inferred from their avoidance of open areas and from behavioral observations of the European pine marten ("Martes
