Black Bears - use pine forests for their
dens. Timber harvesting, as well as land cleared for agriculture and urban
expansion, has severely decreased the available black bear habitat.
In some areas of Minnesota, for example, white pines are being replanted
to help increase the diminishing population of black bears. |

White Pine weevil - a parasite that feeds
on the white pine, and other evergreens. The weevil sticks its long
mouth into the tree, and eats the softer inner tissues. They lay
their eggs in the tree and larvae tunnel into the tree cutting off much
of the trees water supply, causing it to wilt and often die. |
Kirtland Warbler -- a small bird who
uses the jack pine for its nest. Jack pines are dependent on fires
for their survival, but humans have dramatically decreased the number of
fires -- and subsequently decreased Kirtland warbler habitat. The
white pine is moving into regions once covered with jack pine and further
reducing Kirtland warbler nesting sites.
