1 8-Digit HUC Watershed Prioritization in Arkansas - Risk Assessment Matrix Approach 2014 Update Threatened and Endangered (T&E) Species Dharmendra Saraswat, Ph.D. Associate Professor/Extension Engineer Biological and Agricultural Engineering Dsaraswat, 501-681-5987 (cell) ANRC NPS Annual Stakeholder Meeting, September 17, 2014

2 What is Arkansas Watershed Prioritization Approach? Pro-active stakeholder participation A comparative risk assessment based collaborative process that integrate scientific analysis and stakeholder deliberation ANRC NPS Annual Stakeholder Meeting, September 17, 2014 For further details please refer: Fact sheet #FSPPC 116- Watershed prioritization for managing nonpoint source pollution in Arkansas. Available at http://www.uaex.edu/publications/pdf/FSPPC116.pdf ANRC NPS Annual Stakeholder Meeting, September 17, 2014

3 What Data Sources are considered? ANRC NPS Annual Stakeholder Meeting, September 17, 2014 Federal State ANRC NPS Annual Stakeholder Meeting, September 17, 2014 NASS Data, Census Data, 303(d) list, Land Use Land Cover, and Road network

6 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
