Both members of the weasel family, fisher and marten tend to inhabit similar areas within their habitat range while competing with one another over valuable resources and food within that habitat. However, while the larger Fisher has managed to adapt immensely well to agricultural, suburban, and slightly more southern expanses of its home range, the marten is far more fickle with regard to altered habitat impact.
Trappers assist biologists with Wolverine ecology insight
Amid the technology age of satellite mapping and swelling popularity of trail cameras, wildlife experts are still tapping the fur trappers’ knowledge to seek out important data on elusive predators. In Alberta, for example, biologists are looking to gain a better understanding of wolverine distribution across the Canadian province, and reaching back through decades of trapper reports and observations to do it.
Alberta Trappers play key role in Fisher reintroduction
Last year’s rodent “bumper crop” means predator boom this spring
Predator "preservationists" pounce on Fisher population trends
Is New Hampshire finding its way out of a cyclical “boom and bust” fisher trend? Current data is great for checking trends, but does it give you the root cause of a perceived decline? Biologists have stated fisher appear to be adapting (and thriving) in more urban areas; have these creatures forgone the dense hemlock groves where trappers roam for the dumpsters and back decks of suburban sprawl?
