Draft Environmental Assessment Addressing Use of
Glyphosate-Tolerant Soybeans and Corn on National Wildlife Refuge System Lands
Is Available for Public Review

Comments Accepted From February 2nd through  March 4th, 2011

In accordance with the National Environmental Policy Act, the Fish and Wildlife Service (Service) has completed a Draft Environmental Assessment (EA) to analyze the potential effects of using glyphosate-tolerant corn and soybeans for habitat restoration and management on National Wildlife Refuge System (NWRS) lands in the States of Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming.  The Service is seeking public comments on this Draft EA through March 4th, 2011 and will consider all comments and information before adopting a final EA.

In accordance with the NWRS Policy regarding compatible refuge uses, a Draft Compatibility Determination Review for the same use is also included and is available for review and comment. 

Glyphosate-tolerant (“Roundup Ready”) corn and soybeans have been genetically modified through insertion of a gene which allows the plant to tolerate applications of glyphosate.  When applied to nearly all other species of growing plants, glyphosate kills the plant.  The use of glyphosate tolerant crops allows for the effective control and elimination of noxious weeds and other undesirable plants prior to the area being reseeded to native grasses and wildflowers.   

An electronic copy of the Draft EA and Draft Compatibility Determination Review may be downloaded from the following website:   If you do not have access to the internet, a copy may be obtained by writing to: Tom Koerner c/o Sand Lake National Wildlife Refuge Complex, 39650 Sand Lake Drive, Columbia SD 57433, or by email at  

Comments on the Draft EA can be emailed to or mailed to Tom Koerner c/o Sand Lake National Wildlife Refuge Complex, 39650 Sand Lake Drive, Columbia SD 57433.
