Proposed Revision- Time line 1.During 2013 ANRC NPS Annual Stakeholder meeting, a proposal to include Threatened and Endangered (T&E) species in the matrix was considered 2.A workgroup was formed to discuss adding T & E species as matrix variable 3.The group met on November 6, 2013 and May 28, 2014 and came up with an approach for consideration by the stakeholders group ANRC NPS Annual Stakeholder Meeting, September 17, 2014
