River Thame Catchment IFAs

Identification of locations of key importance for freshwater biodiversity in the River Thame Catchment

To underpin conservation action Freshwater Habitats Trust, in partnership with River Thame Conservation Trust and Thames Water, undertook analysis to identify the Important Freshwater Areas of the River Thame Catchment (IFAs). IFAs are locations of regional or national importance for freshwater biodiversity where protection, restoration and expansion should be prioritised to stem the decline in freshwater biodiversity. Here the analysis focused on a river catchment level and the IFAs identified are of local or catchment importance.
IFAs typically comprise of groups of important freshwater habitats or wetlands, or areas with significant concentrations of freshwater Species of Conservation Concern (SOCCs).

Within the River Thame Catchment, ten areas were identified as Important Freshwater Areas at the catchment scale (these are called ‘catchment IFAs’). Four areas were classified as potential Important Freshwater Areas (pIFAs), these are location with more limited data where further survey and investigations might elevate them to full IFA status in due course.

For more information on the IFA analysis please read the full report.

Thame IFAs

  • Broughton
  • Chalgrove Brook Upper Catchment
  • Holton Brook and Shabbington Wood
  • Marsworth Gravel Pit Lakes
  • River Thame and Floodplain at Chearsley
  • River Thame and Lakes at Dorchester
  • River Thame and Floodplain from Waterstoke to Shabbington
  • Spartum Fen SSSI
  • Stadhampton Waters
  • Wendover

Thame pIFAs

pIFAs (or potential IFAs) are locations where there is insufficient data to award full IFA status, but it is suspected that further surveys and investigations may identify it as a key area.

  • Chilterns Headwaters and Springs
  • Lower Denham
  • River Thame and Floodplain at Cuddesdon
  • Wells Farm

Other areas

The IFA concept can be applied to any area. Other areas with available IFA reports include:


The IFA analysis for the Thame Catchment was funded by Thames Water and undertaken through a partnership project with the River Thame Conservation Trust.
