Southern Region Threats
Brook trout no longer occur in 40% of their historical range in the region. Researchers have identified a unique strain of brook trout called the southern Appalachian brook trout (SABT). This heritage strain is the keystone species of the southern Appalachians and is an important biologic, economic and recreational asset to the region. One special southern habitat is the valley spring creeks, where brook trout loss is nearly 100%. The remaining trout are generally isolated in the headwater streams, mostly on public lands.
