Rowan Ecology & Education Support are licensed to carry out freshwater pearl mussel surveys throughout Scotland and England.

Timings of Surveys

Any time of year, however the British weather can cause considerable constraints to carrying out surveys in rivers.  It is best to avoid periods of heavy rain both during and immediately prior to surveys.

Recently Ross has surveyed rivers in Cumbria (River Ehen SAC) and Tayside (River Tay SAC).
