Archived 2017 topics: Knysna Woodpecker (Campethera notata): request for information

This discussion was first published as part of the 2016 Red List update. At the time a decision regarding its status was pended, but to enable potential reassessment of this species as part of the 2017 Red List update this post remained open and the date of posting was updated.

BirdLife species factsheet for Knysna Woodpecker: http://www.birdlife.org/datazone/species/factsheet/22680910

This species is thinly dispersed and endemic to the coastal lowlands of South Africa, with a range of c.50,000 km2, and a population size of 1,000-3,300 mature individuals (Taylor et al. 2015). It is currently classified as Near Threatened on the basis that its small population may approach the threshold for classification as Vulnerable under criterion C1.

There is little information about population trends but it has been recently listed as Near Threatened in the 2015 Eskom Red Data Book of Birds of South Africa, Lesotho and Swaziland (Taylor et al. 2015) based on inferred population declines due to loss of habitat in the Eastern Cape. Lee et al. (in press) suggest instead there may have been a very slight range increase. We request further information on any population trends, and confirmation of a halt in declines which may mean this species qualifies for downlisting to Least Concern.

  1. James Westrip (BirdLife) says:

    Based on available information, our proposal for the 2016 Red List would be to pend the decision on this species and keep this discussion open until 2017, while leaving the current Red List category unchanged in the 2016 update.

    Final 2016 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  2. James Westrip (BirdLife) says:

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2017 Red List would be to list:

    Knysna Woodpecker as Near Threatened under criterion D1.

    There is now a period for further comments until the final deadline of 4 August, after which the recommended categorisations will be put forward to IUCN.

    Please note that we will then only post final recommended categorisations on forum discussions where these differ from the initial proposal.

    The final 2017 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  3. James Westrip (BirdLife) says:

    Recommended categorisation to be put forward to IUCN

    Following further review, the recommended Red List category will remain as in our preliminary proposal, but with a different criteria string:

    Near Threatened under criteria C2a(ii); D1.

    Final 2017 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.
