Condition of the site (state), by habitat
Habitat	Habitat detail	Reference area (ha)	Actual area (ha)	Habitat quantity (% remaining)	Habitat quality (carrying capacity)	Result
Shrubland	Shrubland - Cape (fynbos)	0	0	moderate (70-90%)	poor (40-69%)	very unfavourable

Conservation actions taken at the site (response)
Protected-area designation	Management planning	Other conservation action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	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	medium
