The Southeast Conservation Adaptation Strategy (SECAS) is a shared, long-term vision for lands and waters that sustain fish and wildlife populations and improve human quality of life across the southeastern United States and Caribbean. SECAS provides regional focus for investments across organizations, disciplines, and partnerships on shared and proactive goals. The unique role of SECAS is to identify and support the steps necessary to regionally plan, implement, and evaluate actions that sustain habitat, mitigate threats, and adapt to desired conditions. As a result, SECAS unifies the delivery of conservation activities and supports innovation that can be applied across the region. Funding for this project supports a SECAS Coordinator. The Southeast Conservation Adaptation Strategy (SECAS) was first proposed and approved by the Directors of the Southeastern Association of Fish & Wildlife Agencies (SEAFWA) at their 2011 Annual Conference in Nashville, Tennessee. Through the collaborative forum and scientific capacity provided by the Landscape Conservation Cooperatives (LCCs) overlapping the SEAFWA region, it was envisioned that SECAS would provide a blueprint of the future conservation landscape of the southeastern United States. The Southeast Conservation Adaptation Strategy (SECAS) is an ambitious effort to harness the power of collaboration and leverage scientific, technical, and financial resources to proactively pursue a more resilient landscape to sustain fish and wildlife. The goal of SECAS is to define and describe an ecologically connected network of landscapes and seascapes in the Southeast that represents our collective conservation interests and will sustain fish and wildlife through the 21st century. An adaptation strategy recognizes that the dynamic nature of landscape change across the Southeast demands that we deliver conservation action more strategically than we have in the past and more comprehensively than we are at present.
