Executive Summary

In 2018-2019, the Southeast Association of Fish and Wildlife Agencies’ (SEAFWA) Wildlife Diversity Committee (WDC or Committee) developed a list of Regional Species of Greatest Conservation Need (RSGCN) to enhance their ability to work collaboratively and proactively to sustain populations of both endemic and shared Species of Greatest Conservation Need (SGCN) across the southeast U.S. Regional work can enhance efficiency and conservation effectiveness to promote recovery and prevent the need to list where possible through shared expertise, data collection and analysis, regional information availability, and coordinated actions. The list can guide and facilitate collaboration with conservation partners in the region and leverage support from diverse funding sources by presenting information on many of the unique, rare, and declining biodiversity shared across the southeastern United States.

The SEAFWA RSGCN list captures the remarkable endemism and biodiversity of the region, particularly in aquatic habitats, and highlights species that would benefit from regional collaborative conservation. The list can be sorted to deliver customized priorities:

Taxonomic breakdown of southeast RSGCN. All vertebrate SGCN from 15 states’ State Wildlife Action Plans (SWAPs) and selectinvertebrate taxa were considered. Of the approximately 6,700 Species of Greatest Conservation Need, nearly 2,100 SGCN were evaluated. Of that, 960 species met the RSGCN criteria.

Regional Responsibility and Conservation Concern. Nearly one-third of the RSGCN were considered Very High Concern, 44% High Concern, and the remaining 25% were Moderate Concern. Seventy-seven percent of the Very High Concern RSGCN are aquatic species (fishes, mussels and crayfishes). Seventy three percent of the Very High Concern RSGCN are SEAFWA endemic species. Species were not designated in states where they are considered extirpated. However, rediscovery or reintroduction of species anywhere within their natural range may be a priority conservation action”

Conclusions and Recommendations. Updating the RSGCN list at regular intervals will help prioritize actions at the regional scale. Repeating the process between SWAP revisions can inform SWAPs as well as be informed by SWAPs’ SGCN lists for the next RSGCN revision. Improvements and refinements to the process and methods are encouraged to capture additional criteria and emerging issues that are important to the region. The WDC recommended these actions:

There was an overwhelming consensus that there is a need for additional resources to allow state agencies to effectively address the needs of fish and wildlife diversity conservation in the southeast. Specifically, most RSGCN taxa – especially invertebrates – have critical data gaps that, if filled, would inform more effective on-the-ground conservation and monitoring for success. Coordination with marine conservation practitioners was also recommended.

Information about the RSGCN and their key habitats and threats, gathered at the regional scale, can directly inform the next SWAP revision and generate more effective conservation actions taken at the regional scale. Best management practices, standardized data collection, and policy, regulation, or law enforcement can be developed at a regional scale and collaboratively implemented.

The list can be used to communicate state fish and wildlife diversity conservation priorities to their many conservation partners. USFWS can use the RSGCN list in their workplan development and schedule or identifying at-risk species. The Natural Resource Conservation Service and U.S. Forest Service can use the list to identify focal or sensitive species. NatureServe and their state partners can prioritize rank updates for the highest concern species, particularly if emerging threats have been identified. This list can also be used to foster increased communication and collaboration between state agencies, universities, natural heritage programs, land trusts, and other conservation partners.

* Minor revisions include changing a scientific name to reflect current taxonomy or changing the state-level distribution of a species based upon new information. The RSGCN list generally follows accepted taxonomy when the list was created in 2018. When taxonomic revisions result in the splitting of RSGCN taxa into additional species with new geographic distributions, these new taxa may also be a priority for regional conservation efforts even if they are not listed on this website. Please contact your state’s representative to the SEAFWA Wildlife Diversity Committee to suggest minor changes or corrections to the RSGCN list.
