Bald Eagle

Bald eagles are no longer protected under the federal Endangered Species Act and Section 7 consultation with the U.S. Fish and Wildlife Service is no longer necessary. However, bald eagles remain protected under the Bald and Golden Eagle Protection Act. To help landowners, land managers, and others meet the intent of the Bald and Golden Eagle Protection Act, guidelines on how to avoid disturbing nesting bald eagles are available.

1Rational for addition of counties for rayed bean: These counties have been included for the rayed bean based upon current and historical occurrence data. Since 2004, three extant rayed bean populations have been discovered in Ohio streams. Two of these three populations were thought to be extirpated prior to the discoveries and the third population was not known from historical data. Therefore, we feel it is prudent to make our list of counties where the rayed bean may be present reflective of a conservative approach to section 7 consultation under the Endangered Species Act. The rayed bean should be considered potential present in any county on our list where suitable habitat occurs.
