"ABG has led the management and restoration of Piedmont bogs and seeps on public and private land and has seen populations rebound after decades without flowering. The Kentucky Natural Heritage Program, within the Office of Kentucky Nature Preserves, is actively managing habitat containing this species. The Kentucky NHP and North Carolina Plant Conservation Program (NCPCP) have partnered with ABG to reintroduce material propagated ex situ to reintroduce lost populations. If successful, these reintroductions will contribute to developing guidelines to document and inform management across the range that can be shared through the Piedmont Prairie Partnership (PPP) and Southern Appalachian Bog Learning Network (BLN) and inform conservation management actions."

"In 2022, ABG collected roots from the Talladega National Forest in Alabama and the Cherokee National Forest in Tennessee. ABG meticulously cultured mycorrhizal fungi through a well-defined process, including soil debriding, surface sterilization before placement on Fungal Isolation Media, peloton extraction, culturing, and crucial genetic identification. In 2021, ABG identified a diverse range of fungi, including Calonectria, Ilyonectria, Agaricales, Pestalotiopsis, Sordariales, Hypoxylon fuscum, Hypoxylon fendleri, and Xylariaceae. In 2023, ABG is again attempting to isolate known orchid mycorrhizae and have had early success and will identify new fungal isolates in the near future. By identifying known orchid mycorrhizal fungi, ABG will leverage the identified orchid mycorrhizal fungi to improve seed germination methods and enhance the survival rates of plants reintroduced to their natural habitats."

"Atlanta Botanical Garden's Conservation Seed Bank currently contains > 100 P. integrilabia maternal lines (MLs), each contributing to a collection of well over 10,000 seeds. These seeds were collected from various locations, including Talladega National Forest in AL, Cherokee National Forest in TN, Desoto State Park in AL, and two privately owned populations in the Piedmont region of Georgia."
