IBA Monitoring

2013 high not assessed high

Agriculture and aquaculture annual & perennial non-timber crops - small-holder farming happening now majority/most of area/population (50-90%) slow but significant deterioration high
Human intrusions and disturbance work and other activities happening now small area/few individuals (<10%) no or imperceptible deterioration low
Residential and commercial development housing and urban areas happening now small area/few individuals (<10%) no or imperceptible deterioration low
Transportation and service corridors roads and railroads likely in short term (within 4 years) small area/few individuals (<10%) moderate to rapid deterioration low

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
