ZA057
Impendle 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') at the site:
Species Red List1 Season Year(s) Size IBA criteria
Blue Crane Anthropoides paradiseus VU resident - present A1
Southern Bald Ibis Geronticus calvus NT resident - present A1
Blue Swallow Hirundo atrocaerulea EN breeding 1998 present A1
Bush Blackcap Sylvia nigricapillus VU resident 1998 present A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1998) may differ.


IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2013) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2013 near favourable high high
Whole site assessed? State assessed by Accuracy of information
yes habitat medium

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Forest good (> 90%) moderate (70-90%) near favourable
Grassland good (> 90%) moderate (70-90%) near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happening now some of area/population (10-49%) moderate to rapid deterioration high
Climate change and severe weather likely in short term (within 4 years) whole area/population (>90%) slow but significant deterioration high
Biological resource use happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance happening now some of area/population (10-49%) slow but significant deterioration medium
Natural system modifications happening now some of area/population (10-49%) slow but significant deterioration medium
Agricultural expansion and intensification past (and unlikely to return) and no longer limiting some of area/population (10-49%) moderate to rapid deterioration low
Residential and commercial development happening now small area/few individuals (<10%) moderate to rapid deterioration low
Transportation and service corridors happening now small area/few individuals (<10%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other 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 Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity high
