Chalk streams
Chalk streams are globally rare and unique rivers, with the vast majority found in southern and eastern England.
Chalk streams are fed by pure, filtered groundwater from chalk aquifers. Their stable flow, cool, clear, mineral-rich water, and clean gravel beds create an exceptionally productive and specialized habitat for a diverse range of wildlife, including wild trout and water voles.
