Gray fox and fisher trails  Photo D. Brown
        Both gray foxes and fishers were eliminated from the New
England landscape with the general deforestation of the region
in the 17th and 18th Centuries. According to Thoreau the last
gray fox in Concord was shot for bounty in 1810. The history of
fishers is more obscure. He made no mention of their presence
in his home town in the list of wild animals no longer found
there. But he does mention wolverine, which he may have
confused with the fisher. Both the gray fox and the fisher were
forest adapted species. The fox has an unusual talent for a
canid in that it has retractile nails with which it climbs trees.
Fishers, which were also eliminated with the removal of the
forest, depend on trees, especially old ones with natural
cavities, for denning as well as for hunting prey that shelter
     With the regrowth of the eastern forest since the decline of
regional agriculture, both these animals have slowly returned to
reclaim their ancestral ranges. I first encountered the trail of a
gray fox on a frozen pond in Concord in the mid-nineties and a
fisher's trail in Saugus in 1992. Since then both species have
become common in the metropolitan parks and suburban
conservation lands around Boston where there are plenty of old
trees for both.
