Site details
Site description: The IBA covers the confluence of the Tay and Isla rivers, about 15 km north of Perth. The valley floors in this area support a complex of wetland habitats, including shallow lochs, rivers, pastures and some especially diverse marginal fens. Unusual vegetation-types found along the River Tay include unimproved pasture and riverine shingle-beds. The site is important for breeding raptors and wintering waterbirds. Anser anser are from the Icelandic breeding population.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Delineation rationale: First identified in 1989; further sub-sites added in 2000, and boundary readjusted in 2007. 2000 area, 760ha. Digitised onto 1:50,000 scale OS maps.
