The site was identified as important in 2001 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:

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2022) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Biological resource use	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	Unknown	Very little or no conservation action taking place	negligible

Habitat1	Habitat detail	% of IBA
Grassland		56
Artificial/Terrestrial		28
