Dwesa-Cwebe Nature Reserve


IBA Justification

The site was identified as important in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Knysna Turaco Tauraco corythaix LC resident 1998 present A2, A3
African Oystercatcher Haematopus moquini LC non-breeding - present A1
Knysna Woodpecker Campethera notata NT resident 1998 present A1, A2
Grey Cuckooshrike Ceblepyris caesius LC resident 1998 present A3
Olive Bush-shrike Chlorophoneus olivaceus LC resident 1998 present A3
Yellow-throated Woodland-warbler Phylloscopus ruficapilla LC resident 1998 present A3
Spotted Ground-thrush Geokichla guttata VU breeding - present A1
Brown Scrub-robin Tychaedon signata LC resident 1998 present A2
White-starred Robin Pogonocichla stellata LC resident 1998 present A3
Chorister Robin-chat Cossypha dichroa LC resident 1998 present A2, A3
Swee Waxbill Coccopygia melanotis LC resident 1998 present A3
Forest Canary Crithagra scotops LC resident 1998 present A2, A3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1998).

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Whole area of site (>90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
