2.5 Conservation assessment of P. villosa
We performed a conservation assessment using the Extent of Occurrence (EOO) (Moat, 2007; Velzen & Wieringa, 2014) and following guidelines for their interpretation from IUCN (2001). EOO comprises the minimum convex polygon covering all known or predicted sites for the species. It is frequently used as a preliminary assessment tool, such as when a new species is described or when populations of a species are found in new places or were locally extirpated (e.g., Velzen & Wieringa, 2014; Lachenaud et al., 2013). In the case of P. villosa , there had been no prior conservation assessment for the species, and it status is not presently included in the IUCN Red List of Threatened Species (IUCN, 2020). Therefore, we analyzed the EOO using the location data of 155 populations from ecological niche model (Table S2).
