APHIS Environmental Assessment finds No Significant Impact from the Biological Control of Hoary Cress


The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has prepared a final environmental assessment (EA) regarding the biological control of hoary cress.  Hoary cress are invasive plants that impede crop production, minimize grazing potential of rangelands, degrade wildlife habitat and native plant communities, and restrict waterfowl’s use of wetlands and stream banks.  APHIS experts analyzed the effect releasing a mite, Aceria drabae, could have on the human environment and determined its release will not have a significant impact.  On December 5, 2017 APHIS published an EA in the Federal Register for public review and comment.  After reviewing comments received, APHIS prepared the final EA and made the finding of no significant impact.  This action will allow the issuance of permits to release the mite.
