Notice of Availability of a Draft Recovery Plan for the Little Colorado Spinedace for Review and Comment

Resumen

The U. S.

Populations are now known to exist in the upper Little Colorado mainstem, East Clear Creek, Chevelon Creek, Nutriosa and Rudd Creek. Modifications within the Little Colorado River and tributaries and watershed have brought about reduced flows and degraded water quality. These factors plus introduction of non-native fish are believed to be major threats to the species continued existence in its Creek, native habitats. The Service solicits rev
