Zoologists Scott LaPoint and Roland Kays weigh a weasel-like fisher in the wild.

Zoologists Scott LaPoint and Roland Kays weigh a weasel-like fisher in the wild. Fishers, which weigh 4 to 12 pounds, are fierce predators.

For weasel-like fishers it’s a good time to live in the East.  The fierce little carnivores are reclaiming historic habitats, including the Bronx, New York.  But it’s a different story for fishers in the West, which haven’t been as successful in repopulating areas they once roamed in the Pacific and Northwest.

Dr. Roland Kays in the College of Natural Resources at NC State University is part of a team investigating reasons for the regional differences and devising strategies for successful reintroduction.
