Fourteen species of wetland-inhabiting butterfly species of Greatest Coservation Need (SGCN) status were surveyed in 2016 and 2017 at multiple sites across four states - Maryland, New Jersey, Pennsylvania and West Virginia. Survery data was used to evaluate the status of each species in all states where they occurred as well as refine the distribution data for each species across the region. All data points were mapped in ArcGIS and used to model species distribution in terms of both habitat and climate. The results are presented for each species and several examples are explored in greater depth. Best Management Practices (BMPs) were developed for both modeling procedures. A final goal of the project was to intiate habitat enhancement projects in a small number of survey areas in Maryland and Pennsylvania. The results of these projects are still being reviewed by the various NHPs that participated in the projects. Some species will be reassessed as to their conservation status of inclusion as SGCN. Modeling outputs will be used to guide further survey work and prioritize sites for enhancement and protection.
