摘要: Abstract We related winter habitat selection by Canada lynx (Lynx canadensis), relative abundance of snowshoe hares (Lepus americanus), and understory stem densities to evaluate whether select stands with the greatest hare or prey accessibility. Lynx (3 F, 3 M) selected tall (4.4–7.3 m) regenerating clear-cuts (11–26 yr postharvest) established partially harvested (11–21 against short (3.4–4.3 clear-cuts, recent (1–10 yr), mature second-growth (>40 roads their edges (30 m on either side roads). that provided intermediate high density cover for (i.e., access) but exhibited lower preference stand types highest where coniferous saplings exceeded 14,000 stems/ha.
