Valley of the Attert


IBA Justification

The site was identified as internationally important for bird conservation in 2009 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:
Species Red List Season (year/s of estimate) Size IBA criteria
Red Kite Milvus milvus LC breeding (1997–2009) 3–5 pairs C6
Black Kite Milvus migrans LC breeding (1997–2009) 6–9 pairs C6
Common Kingfisher Alcedo atthis LC resident (2000–2009) 6–12 pairs B2, C6
Red-backed Shrike Lanius collurio LC breeding (2000–2009) 30–60 pairs C6
Great Grey Shrike Lanius excubitor LC resident (2006–2007) 10–14 pairs B2

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2009) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2009 poor high low
Whole site assessed? State assessed by Accuracy of information
yes population medium

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Little Owl Athene noctua 7 / 4 (pairs) 100 good
Milvus migrans 9 / 3 (pairs) 100 good
Lanius excubitor 7 / 14 (pairs) 50 poor
Meadow Pipit Anthus pratensis 2 / 15 (-) 14 not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Agricultural expansion and intensification happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Some of area covered (10–49%) No management plan exists, but the management planning process has begun Some limited conservation initiatives are in place low
