The Southeast Conservation Blueprint is the primary product of SECAS. The Blueprint is more than just a map. It’s a living spatial plan to achieve the SECAS vision of a connected network of lands and waters across the Southeast and U.S. Caribbean. More than 450 people from over 180 organizations have used or are using the Blueprint in their work. So far, the Southeast Blueprint has helped bring in more than $270 million in conservation funding to protect and restore over 315,000 acres.

The Blueprint identifies priority areas based on a suite of natural and cultural resource indicators representing terrestrial, freshwater, and marine ecosystems. A connectivity analysis identifies corridors that link coastal and inland areas and span climate gradients. Because the Blueprint is a living plan, it will evolve over time, driven by improvements to the underlying science, our growing understanding of on-the-ground conditions, and input from new partners. So far, more than 2,000 people from over 600 different organizations have actively participated in developing the Southeast Blueprint.

Blueprint categories

Highest priority: Areas where conservation action would make the biggest impact, based on a suite of natural and cultural resource indicators. This class covers roughly 10% of the Southeast Blueprint geography.
High priority: Areas where conservation action would make a big impact, based on a suite of natural and cultural resource indicators. This class covers roughly 15% of the Southeast Blueprint geography.
Medium priority: Areas where conservation action would make an above-average impact, based on a suite of natural and cultural resource indicators. This class covers roughly 20% of the Southeast Blueprint geography.
Priority connections: Connections between priority areas that cover the shortest distance possible while routing through as much Blueprint priority as possible. This class covers roughly 5% of the Southeast Blueprint geography.

A few things to keep in mind as you explore the Blueprint

The Blueprint identifies areas where conservation action would have the biggest impact for a connected network of lands and waters. A range of conservation activities could benefit those priority areas, including management, economic incentives, and protection.
The Blueprint is not intended to be used in isolation of other datasets. Instead, it provides a regional perspective that, in combination with local data and knowledge, can help inform decisions about where to focus conservation action in the face of future change.
As a living spatial plan, the Blueprint is always a work in progress. It is updated annually to incorporate new data and feedback from experts and Blueprint users.
If you want to find your piece of the Blueprint, you can explore the underlying indicator and connectivity data. These layers can help identify important areas for corridors, birds, water quality, climate resilience, prescribed burning, reforestation, and more. They can also help you tell the unique story of what makes your area of interest special. Contact a member of Blueprint user support staff if you’d like some help.

Blueprint methods

Flow chart illustrating the process of creating Blueprint 2024. Each step is described in the text below. — The overall process of developing Southeast Conservation Blueprint 2024.

Step 1: The terrestrial, freshwater, and coastal/marine ecosystems of the Southeast and U.S. Caribbean are represented by 60 natural and cultural resource indicators. They serve as the data building blocks of the Blueprint. Each indicator represents a unique natural feature, cultural resource, or element of ecosystem health. Because they indicate for other apsects of intact, functional ecosystems, the indicators are intended to collectively represent the richness and complexity of the lands and waters of the region, and the necessary components of the connected network called for in the SECAS vision.

Step 2: The SECAS geography is divided into 6 zones created by grouping 22 smaller subregions. Reservoirs are removed from the zones because the current set of indicators does not do a good job of distinguishing the important parts of reservoirs.

Step 3: A conservation planning software program called Zonation ranks the pixels in each zone according to their importance for all the indicators collectively. This ensures that the Blueprint includes high-value areas for every indicator as part of a balanced portfolio. Pixels that rank higher in Zonation become higher priority in the Blueprint. The subregions are also used as inputs to Zonation to better balance priorities within zones. Zonation uses a few simple rules to prioritize.

Step 4: Using a software program called Linkage Mapper, a least-cost path connectivity analysis identifies corridors that link hubs across the shortest distance possible, while also routing through as much Blueprint priority as possible. In the continental Southeast, hubs are large patches (~5,000+ acres) of highest priority Blueprint areas and/or protected lands. In the Caribbean, hubs are large patches (~500+ acres) of highest priority Blueprint areas and/or protected lands.

Step 5: Combining the areas of highest Zonation ranking with the corridors produces Southeast Blueprint 2024. For more details, see the Southeast Blueprint 2024 Development Process final report.

Known issues

As a living spatial plan, the Blueprint is always a work in progress. We maintain a list of the problems with the Blueprint that have been identified in the review process so far, which we call “known issues”. These known issues are part of our commitment to transparently documenting the Blueprint’s strengths and weaknesses. They also help us prioritize the most important issues to fix in the next update cycle.

The known issues identified with Southeast Conservation Blueprint 2024 are captured on the known issues page and in the Southeast Blueprint 2024 Development Process final report.

The history of the Blueprint

A conference room full of conservationists discussing the progress of the SECAS effort — Ed Carter, Executive Director of the Tennessee Wildlife Resources Agency, speaks about the history and importance of SECAS alongside Cindy Dohner, Southeast Regional Director of the U.S. Fish and Wildlife Service. This SECAS symposium took place at the 2016 annual conference of the Southeastern Association of Fish and Wildlife Agencies (SEAFWA).

In the fall of 2013, SECAS leadership set a goal of developing a first-generation Southeast Blueprint for landscape-scale conservation by the fall of 2016. Many different conservation planning efforts were already underway, but most eco-regional plans only covered parts of states, while state-specific plans stopped at the state line. The results of all this parallel planning did not yet add up to an integrated regional strategy.

Three years later, Version 1.0 of the Southeast Blueprint was released in December 2016. Development of this first Blueprint relied heavily on Landscape Conservation Cooperative (LCC) partnerships across the Southeast and U.S. Caribbean. This plan provided the first ever integration of spatial plans developed through the South Atlantic, Appalachian, Gulf Coastal Plains and Ozarks, Gulf Coast Prairie, North Atlantic, Peninsular Florida and Caribbean LCCs. It also included priorities from the Mississippi River Basin/Gulf Hypoxia Initiative spearheaded by seven LCCs (Appalachian, Eastern Tallgrass Prairie and Big Rivers, Great Plains, Gulf Coast Prairie, Gulf Coastal Plains and Ozarks, Plains and Prairie Potholes, and Upper Midwest and Great Lakes).

Version 2.0 of the Southeast Blueprint was released in November 2017. This plan incorporated the improved subregional Blueprints from several LCCs and established priority connections with western states through the Crucial Habitat Assessment Tool. Significant improvements over Version 1.0 included improved consistency across LCC boundaries, improved consistency in climate change response, and improved integration beyond the Southeast.

Version 3.0 of the Southeast Blueprint was first introduced at the October 2018 SEAFWA annual conference, and officially released in February 2019. Its development occurred during a time of transition for the LCC Network where the structure and function of some LCCs was changing. Despite these changes, the capacity and commitment to continue to support Blueprint users and improve the Southeast Blueprint remains strong, evidenced by the many examples of Blueprint implementation, as well as progress on Blueprint improvements. Blueprint 3.0 added full coverage of Texas, integrated threat layers covering the full Southeast, and a hubs and corridors layer covering part of the region.

Version 4.0 of the Southeast Blueprint was released in October 2019 at the SEAFWA annual conference. Improvements over the previous version included: corrected overprioritization in Texas, Oklahoma, and the mountains of West Virginia and Virginia; improved priorities in the Lower Mississippi Valley, Louisiana marshes, and the Southern Appalachians; updated inputs from Florida and the Middle South subregion; expanded marine coverage to include state and federal waters around Florida; and expanded hubs and corridors that now cover all of Florida.

Southeast Blueprint 2020 was released in October 2020 at the virtual SEAFWA annual conference. Significant improvements over the previous versions included: finer resolution and a more connected network of priorities in the inland South Atlantic subregion; updated data and a more consistent approach to cross-state prioritization in the Middle Southeast subregion; and better integration in areas of overlap between the South Atlantic Blueprint, Florida Blueprint, and Nature’s Network design.

Southeast Blueprint 2021 was released in November 2021 following the virtual SEAFWA annual conference. Significant improvements over the previous versions included: updated and improved indicators, better incorporation of equity, deep-sea coral, fire, and important grasslands, and multiple connectivity improvements in the South Atlantic subregion, as well as correcting a scoring issue in the Middle Southeast subregion.

Southeast Blueprint 2022 was released in October 2022 at the SEAFWA annual conference. Rather than continuing to stitch together so many different subregional plans, the 2022 Blueprint took massive strides toward regional consistency by using the same methods and indicators across 15 states of the Southeast. To provide more complete coverage of the SECAS geography, it also incorporated two additional input plans: the latest update to the Florida Marine Blueprint for marine areas in Florida and the Caribbean Landscape Conservation Design for inland areas in Puerto Rico.

Southeast Blueprint 2023 was released in October 2023 at the SEAFWA annual conference. For the first time, this Blueprint used a consistent approach across the entire geography and did not have to stitch together any subregional inputs. The 2023 Blueprint expanded consistent methods and indicators to Puerto Rico, the U.S. Virgin Islands, and nearshore U.S. Caribbean waters, as well as to the full extent of U.S. waters in the Atlantic Ocean and Gulf of Mexico. This update significantly improved the older expert-driven, watershed-scale priorities for Puerto Rico, and the previous priorities for parts of the Atlantic and Gulf marine areas. It added new coverage of the U.S. Virgin Islands, U.S. Caribbean nearshore waters, and the rest of the Gulf and Atlantic marine environment. It also included minor refinements to the inland continental Southeast priorities and updated hubs and corridors for the full Blueprint area.
