Sone tidal flat


IBA Justification

The site was identified as internationally important for bird conservation in 2004 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
Kentish Plover Charadrius alexandrinus LC passage (2003) present A4i
Whimbrel Numenius phaeopus LC passage (2003) present A4i
Grey-tailed Tattler Tringa brevipes LC passage (2003) present A4i
Saunders's Gull Saundersilarus saundersi VU winter (2003) present A1, A4i

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.

Whole site assessed? State assessed by Accuracy of information

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Marine Intertidal good (>90%) poor (40–69%) poor

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Transportation and service corridors likely in long term (>4 years) few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Little/none of area covered (<10%) No management planning has taken place Some limited conservation initiatives are in place very low
