Designation Definitions
PEP = Plant Extinction Prevention = Taxon has fewer than 50 individuals in the wild
PEP-Extinct in wild = Wild founders extinct, outplanted progeny exists that serve as founders; taxon
has fewer than 50 individuals in the wild.
PEP-Extirpated in wild = wild founders extirpated on the island, outplanted progeny exists that serve
as founders; taxon has fewer than 50 individuals in the wild.
PEP-EXTINCT? = (Possibly extinct) Taxon not seen for over 20 years, habitat remains, some hope of
discovery remains (refers to entire species)
POP = POtentially PEP = Taxon has more than 50 but extremely vulnerable
ROI = Rare On Island = Taxon that occurs on other islands but is rare on a particular island (<50)
EXTIRPATED? = (Possibly extirpated) Taxon not seen for over 20 years; habitat remains, some hope
of discovery remains (refers to island-level extirpations)
EXTIRPATED = Not located despite extensive searches, very little hope of discovery remains (refers
to island-level extirpations)
EXTINCT = Not located despite extensive searches, very little hope of discovery remains
TBD = To be determined.
