Saint Augustin Forest This is an IBA in Danger! 


IBA Justification

The site was identified as important in 1999 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
Running Coua Coua cursor LC resident 1997 present A2, A3
Verreaux's Coua Coua verreauxi LC resident 1997 present A1, A2, A3
Olive-capped Coua Coua olivaceiceps LC resident 1997 present A3
Archbold's Newtonia Newtonia archboldi LC resident 1997 present A2, A3
Red-shouldered Vanga Calicalicus rufocarpalis VU resident 1997 present A2, A3
Lafresnaye's Vanga Xenopirostris xenopirostris NT resident 1997 present A2, A3
Sickle-billed Vanga Falculea palliata LC resident 1997 present A3
Subdesert Brush-warbler Nesillas lantzii LC resident 1997 present A2, A3
Sakalava Weaver Ploceus sakalava LC resident 1997 present A3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1999).

2017 unfavourable very high high
Was the whole site assessed? State assessed by Accuracy of information
no habitat medium

State (condition of the trigger species' habitats)
Habitat Habitat detail Reference area (ha) Actual area (ha) Habitat quantity (% remaining) Habitat quality (carrying capacity) Result
Forest 0 0 moderate (70-90%) moderate (70-90%) unfavourable
Wetlands (inland) 0 0 good (> 90%) good (> 90%) favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Biological resource use logging & wood harvesting - intentional use: subsistence/small scale past (and unlikely to return) and no longer limiting whole area/population (>90%) slow but significant deterioration low
Biological resource use logging & wood harvesting - unintentional effects: large scale happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Human intrusions and disturbance work and other activities likely in long term (beyond 4 years) majority/most of area/population (50-90%) very rapid to severe deterioration high
Residential and commercial development housing and urban areas happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high

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 comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species The conservation measures needed for the site are being comprehensively and effectively implemented high
