Justification:
|
The last assessment (Cronk 1980) listed P. adscensionis as Endangered. It should now be considered as Critically Endangered using the new IUCN codes. Information comes from literature sources and personal observation. The population has been stable over the last five years but as it is known mostly from one location on Ascension it is extremely susceptible to extinction in the near future.
