Marten space use and habitat selection in managed coniferous boreal forests of eastern Canada
Abstract Effects of habitat loss and fragmentation on the behavior of individual organisms may have direct consequences on population viability in altered forest ecosystems. The American marten ( Martes americana ) is a forest specialist considered as one of the most sensitive species to human‐induc...

As some studies have shown that martens cannot tolerate >30–40% clear‐cuts within their home range, we investigated marten space use (home range size and overlap) and habitat selection in landscapes fragmented by 2 different patterns of timber harvesting in the black spruce boreal forest: dispersed‐cut landscapes (10–80 ha cut‐blocks) and clustered‐cut landscapes (50–200 ha cut‐blocks).

However, female body condition was correlated to habitat condition inside their home ranges (i.e., amount of residual forest and recent clear‐cuts). At the home range scale, we determined that mixedwood forests were also among the most used forest stands and the least used were recent clear‐cuts and forested bogs, using resource selection functions. At the landscape scale, home ranges included more mixedwood forests than random polygons and marten high activity zones were composed of more residual forest and less human‐induced disturbances (clear‐cuts, edges, and roads). These results suggest that mixedwood forests, which occupy approximately 10% of the study area, play a critical role for martens in this conifer‐dominated boreal landscape.

Abstract Effects of habitat loss and fragmentation on the behavior of individual organisms may have direct consequences on population viability in altered forest ecosystems.
