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 |
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.
