"Soutiere (1979) reported that marten populations were reduced by two-thirds on an area of extensive commercial clear-cutting as compared to adjacent uncut or partially cut areas." (p. 175)

"Our methods also gave insight into marten activities within the different habitats. Hunting, as indicated by a search pattern of circling and zig-zagging about a localized area, was associated with uncut and partially cut stands. Clear-cuts may have been underused because of poor hunting conditions for marten in this habitat. Our observations and other studies (Marshall 1951, Campbell 1979) have shown that marten use leaning trees, fallen logs, and other debris protruding above the snow for below-snow access while searching for prey in winter. The structure of slash resulting from clear-cutting may differ substantially from that resulting from natural tree mortality in an uncut forest. The generally smaller-diameter material protruding out of the snow in clear-cuts may not provide adequate access." (p. 181)
