IBA Monitoring

2010 low favourable medium
Medium - based upon reliable but incomplete / partially representative data

Biological resource use logging & wood harvesting - unintentional effects: large scale past (and unlikely to return) and no longer limiting majority/most of area/population (50-90%) slow but significant deterioration low
Energy production and mining mining and quarrying happening now some of area/population (10-49%) no or imperceptible deterioration low

Numenius phaeopus Whimbrel 70 70 breeding pairs 100 favourable
Picoides tridactylus 35 35 breeding pairs 100 favourable

Most of site (50-90%) covered (including the most critical parts for important bird species)  A management plan exists but it is out of date or not comprehensive  Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity  medium
