2.9 Mitigation Effectiveness Monitoring and Adaptive Management Plan I n the Final Solar PEIS, the BLM committed to developing and incorporating a monitoring and adaptive management plan into its solar energy program. The BLM “Assessment, Inventory, and Monitoring Strategy for Integrated Renewable Resources Management” (AIM Strategy) (Toevs et al. 2011) will guide the development of a Dry Lake monitoring plan that will inform management questions at multiple scales of inquiry (e.g., the land use plan area, mitigation area, project area, and treatment). Detailed information about how the AIM Strategy will be implemented to support long-term monitoring of solar development is provided in Appendix A, Section A.2.4 of the Final Solar PEIS. This monitoring plan will also be consistent with and complement the BLM regional and national monitoring activities. In the context of solar energy development, long-term monitoring should be conducted to (1) evaluate the effectiveness of mitigation measures, including avoidance measures, onsite mitigation, and regional mitigation; (2) detect unanticipated direct and cumulative impacts at the project and regional level; and (3) evaluate the effectiveness of elements of the BLM’s solar energy program (e.g., policies, design features). To ensure that investments in regional mitigation actions are effective and that regional mitigation goals and objectives are being met, it is critical that the longterm monitoring plan include monitoring objectives specific to the regional mitigation locations and actions. The findings of the long-term monitoring activities will be examined by the BLM to support adaptive management of solar development (i.e., to identify the need to adjust operational parameters, modify mitigation measures, and/or implement new mitigation to prevent or minimize further impacts). The following steps will be conducted to develop the mitigation effectiveness monitoring plan for the Dry Lake SEZ: Step 1. Developed Management Questions and Monitoring Goals. The BLM interdisciplinary team developed management questions to articulate the issues of concern related to monitoring mitigation effectiveness. The management questions provide the basis for developing monitoring goals. The management questions and monitoring goals for the Dry Lake SEZ are provided in the two text boxes that follow. Management Questions Established for the Dry Lake Solar Regional Mitigation Strategy 1. Were the design features of the solar development effective to contain the impact of solar installation to the project site (e.g., trend of attributes, special status species habitat indicators, invasive species, habitat metrics)? 2. Are the avoidance areas maintaining ecological composition and process similar to those adjacent to the project area? 3. Did the regional mitigation actions achieve their objectives? 4. Were the Dry Lake Solar Energy Zone (SEZ) mitigation actions, collectively, effective in improving the trend of rangeland health attributes and landscape metrics in the regional mitigation site(s)? 5. What is the status and trend of rangeland health attributes for critical ecological processes necessary to sustain the Mojave Desert ecosystem at three scales: the Dry Lake SEZ 2-mile buffer area, the mitigation area(s), and the Mojave Basin and Range ecoregion? (Note: Some impacts may need to be assessed at different distances (e.g., watershed, airshed).) REGIONAL MITIGATION STRATEGY FOR THE DRY LAKE SOLAR ENERGY ZONE • TECHNICAL NOTE 444 • 35
