<br />Figure 3 -5. Dams and major rivers in North Carolina. Existing threats to aquatic habitats and species, such as
<br />hydrological alteration, may be exacerbated by climate change.
<br />As the availability of cool water habitat contracts,
<br />priority species that inhabit cooler headwaters, such
<br />as Johnny darter (Etheostom a nigrurn), striped shin-
<br />er (Luxulis chrysocephalus), and slippershell mussel
<br />(Alasmidonta viridis) may be more at risk. Recre-
<br />ationally important fisheries, for example those
<br />stocked in cold and cool water hatcheries in the
<br />state, such as walleye (Sander vitreus), muskellunge
<br />(Esox masquinongy), and trout species, are also likely
<br />to be affected. Box 3 -1 includes a detailed assess-
<br />ment of temperature impacts on brook trout (Salve -
<br />linus fontinalis). Sessile organisms unable to move
<br />to more suitable habitats, such as temperature-sensi-
<br />tive mussel species, may be particularly at risk. For
<br />example, Appalachian elktoe (Alasmidonta ravene-
<br />liana) populations are already restricted to scattered
<br />pockets of suitable habitat consisting of cool, clean
<br />well - oxygenated water (NatureServe 2009).
