Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,iii); D2 ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Cumberlidge, N.
Reviewer(s): Crandall, K. and Daniels, S. and McIvor, A.
Listed as Vulnerable under B1 and D2 because its extent of occurrence is less than 20,000 km² and it is known from less than five localities, with a threat of increasing habitat disturbance from population growth in the region. The population size is estimated at greater than 1,000 but fewer than 10,000 mature individuals over the entire range (based on its relatively low representation in museum collections, which is interpreted here as reflecting a potentially low population level (although under collecting could equally explain these low levels). A continuing decline in extent of occurrence is inferred from the fact that P. pilosus has been known to scientists for more than 60 years and yet still is poorly known, although a few specimens have been collected recently (in the past five years).

Population [top]

Population:It is difficult to estimate the population status and trends of this species, but its population is estimated to be declining based on indirect measures such as lack of recent collections of specimens, a relatively poor representation in museum collections and increasing habitat disturbance associated with growing human populations in the region.
Current Population Trend:Unknown
