In 1997, the Virginia Department of Game
and Inland fisheries began a statewide headwater stream sampling program. While the
project allows us to exercise our curiosity for "what lies beneath the surface",
the primary goal is to develop and maintain a fisheries database and classification system
for our headwater streams and use it to direct restoration, management, and habitat
protection efforts. Project objectives include: (1) identifying streams that do or could
support sustainable fisheries through restoration and/or management efforts; (2)
developing a long-term monitoring plan to evaluate changes in fish communities related to
large-scale anthropogenic impacts; and (3) determining the distribution of threatened and
endangered species in relation to drainage basin, habitat, and fish community attributes.
Project protocols are borrowed from existing fish and habitat sampling programs like those
of the U.S. Geological Survey and the Ohio Environmental Protection Agency. In 1977,
survey areas were delineated by using U.S. Department of Agriculture Natural Resource
Conservation Service watersheds. In 1998, we plan to survey larger geographic areas by
sampling within U.S. Geological Survey hydrologic units or biologically similar
"regions" resulting from overlaying drainage and physiography. Collaborative
work is being conducted with Dr. Paul Angermeier at Virginia Tech to develop models for
determining optimum sampling regimes within geographic areas and for predicting species
presence or absence in unsampled locations. The presence and absence models may provide a
basis for us to prognosticate on stream reaches where restoration, management, and habitat
protection efforts could be directed.
