Ecology of American martens in the transitional boreal-deciduous forests of Adirondack Park

Ecology of American martens in the transitional boreal-deciduous forests of Adirondack Park
American martens (Martes americana) are small, forest-dependent carnivores that rely on complex forest structure to meet their life history requirements. Previous research in the northeastern U.S. has also demonstrated that marten populations are closely linked with pulsed mast crops (e.g., as produced by American beech (Fagus grandifolia) and American mountain ash (Sorbus americana)). These pulses result in strong bottom-up effects that have both immediate and time-lagged consequences on these predators and their small mammal prey. Please join us as Dr. Jensen discusses the fascinating natural history of these carnivores and his previous research in Adirondack Park, and shares recent results of American Wildlife Conservation Fund sponsored research to develop and deploy small (approx. 30 g) GPS collars on martens to better understand movements and space use relative to mast pulses.

Thank you for posting this presentation. Very informative and helps understand this animal.

Also, you will find with the Covid situation that Fisher and Marten have been effected, Mink populations have bottomed out, where I would take 30 40 mink this year alone I only took 1, tracks and sign no longer show, and the lower Adirondack population of Fisher/ Marten have as well been effected.

I can't seem to find an email for Paul Jensen. I have lots of observations and questions about pine martens here in British Columbia. I now can identify 4 specimens that are visiting my remote cabin and they exhibit different behaviour, some obvious different bib patterns and colours, but also sizes. I can't be sure of the sex but the size and tail length make me think I have at least 1 juvenile so I'd like to know from an expert to see what I'm dealing with. Thanks.

One of the things I have found, Martens are preyed upon heavily by coyotes. in the areas where I trap, where the population of coyotes are high both Fisher and Marten populations are the lowest. In areas where I have harvested coyots early in the season, my Fisher/Marten catch increases as the season progresses.
