This study used the NatureServe system to generate provisionary subnational conservation status ranks (s-ranks) for the vascular flora of Tennessee using five methods: (1) assigning an s-rank based on surrounding state s-ranks, (2) assigning an s-rank based on the percentage of counties with an occurrence record, (3) using FME to calculate criteria and assign an s-rank, (4) using RareCat to calculate criteria and assign an s-rank, and (5) using ArcGIS Pro to calculate criteria and assign an s-rank. These methods generated provisionary s-ranks for 99% of Tennessee’s flora (2,992 species). A manual was created on how ArcGIS Pro can be used to calculate criteria and assign provisionary s-ranks, which was shared with NatureServe and their state-level partners to further ranking efforts.","abstract_html":"Conservation status ranks measure the potential risk of extinction for species at the global, national, and subnational levels, taking into account rarity, threats, and population trends.
