Freshwater Biological Monitoring

Macroinvertebrate sampling in the River Almond, October 2004

Flows were very high after recent rain
The procedure for kick-sampling was explained,
And demonstrated
Then everyone took a turn at sampling
Due to the conditions, samplers were roped up for safety
In the lab, invertebrates were sorted from the rest of the material
