In-Depth Information
survival and reproduction are not obtainable or too scant for making compar-
isons with habitat use, surrogates (e.g., body size, home range size) may, in
some cases, be appropriate and could add measurably to assessments of habi-
tat quality.
Surprisingly, even intensive, long-term studies of radiocollared animals
with detailed data on both habitat use and demographics have typically not
attempted to relate the two. This should be a goal for the future.
Acknowledgments
I thank K. V. Noyce and T. K. Fuller for many thoughtful discussions about this subject,
and participants of the workshop for their input following my presentation. K. V. Noyce,
P. L. Coy, M. S. Boyce, and W. F. Porter provided helpful suggestions on the manuscript.
The Minnesota Department of Natural Resources supported my study of black bears,
which stimulated my thinking about habitat evaluation and prompted me to use a study
design like that described at the end of this chapter.
