Grizzly Bear Tree Rub Project
Long term monitoring of the grizzly bears activity range is
a goal of this research project. Currently, we need an
additional $20,000 to complete a match challenge to support the
remainder of this project.
The Northern Continental Divide Ecosystem (NCDE) which includes
all of Glacier National Park, the Bob Marshall Wilderness and
the millions of acres of public lands is the home of about 765
grizzly bears as determined by Kate Kendall after a large DNA
sampling study. Their goal was to count grizzlies in a unique
and non-invasive manner by capturing their hair from barbed wire
catches.
The study does not mean that grizzly bears in the NCDE will be
taken off the endangered species list any time soon. It simply
provides a baseline count of how many grizzlies are in this area
and where the grizzly bear populations habitat. To de-list the
bears, a host of criteria must still be met, including a trend
monitoring study that will examine whether bear populations are
increasing or decreasing. 2005 was a bad year for the grizzly
bear and bear mortality that year was twice the sustainability
rate, according to Kendalls study. In 2007, at least 35
grizzlies were killed in the NCDE region. However, since 1999,
there has only been a single human-caused grizzly mortality in
Glacier National Park. The Park has strict garbage protocols
including the bear-proof storage lockers (purchased by GNPF) for
fore and back country campgrounds mostly in wilderness areas.
A gift of $5,000 will allow you to receive periodic updates
about this project along with an opportunity to take a hike with
a USGS biologist from the project to look at their tree rub
findings.
