Question

Grizzly bear (Ursus arctos) management in the Greater Yellowstone Ecosystem (GYE) is
one particularly high-profile case. Threats to grizzly bears may be defined in terms of
habitat and population fragmentation and the biological measures needed to maintain or
restore populations (e.g., Knight et al., 1999). However, they may also be understood as
an interdisciplinary management problem, realizing that the conservation of grizzly bears
and their ecosystem are only partly a technical problem and largely an outcome of
complex human social dynamics—a policy process. Understanding this policy process
and making it more effective is the key to achieving effective grizzly bear and ecosystem
conservation. This paper first offers a brief overview of the policy process. Second, it
examines three basic interdisciplinary problem solving elements or perspectives that can
be applied to species and ecosystem conservation.

a. This is a complex problem.
b. Environmental science is an interdiscipline and is therefore sufficient to
address this problem.
c. This problem could draw on insights from ecology, sociology, psychology, as
well as environmental science as there are human as well as animal behaviors
that must be considered.
d. This problem cannot be solved.
e. “a” and “c” are correct.

Answer 1

e. “a” and “c” are correct.
