Definition of Destruction or Adverse Modification
The proposed revised definition of "destruction or adverse modification" focuses the Services' review of federal actions on how they would affect the designated critical habitat's ability to support recovery of species protected by the ESA. In this review, we looked at how the action may affect the quantity and quality of habitat features, the ability of that habitat to support the species throughout its life cycle, and the ability of the habitat to meet the species' recovery needs; in other words, how the "conservation value" of the critical habitat is being affected.
The proposed definition codifies our practices and provides a clear and consistent benchmark for determining "destruction or adverse modification."
The public comments period for this proposal closed October 6, 2014. We are currently working to respond to these comments and plan to finalize the definition in the summer of 2015.
