Technical Bulletin No. 0728: Influence of Landscape Pattern, Forest Type, and Forest Structure on use of Habitat by Marten in Maine

American marten (Martes americana) are generally considered an associate of mature forests and their populations are susceptible to over-harvesting and habitat loss. Despite the potential for clearcutting to fragment habitat of area-sensitive, forest-dependent species such as marten, few studies have evaluated the influence of landscape pattern on use of habitat and spatial distribution of marten in areas with extensive timber harvesting. Thus, we examined relationships among measures of landscape pattern and spatial use of habitat by 33 (17 male and 16 female) resident and 32 (17 male and 15 female) non-resident adult (> 1 year) marten in an extensively logged landscape.
