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).
