Aquatic macrophyte assessments

We are regularly contracted to conduct botanical surveys and to provide expert advice on management options for the sensitive removal of aquatic plants from recreational waters used for fisheries and water sports.

Our aquatic macrophyte assessment services are co-ordinated by our expert team of aquatic botanists, who have individual specialisms covering riverine, lacustrine and estuarine habitats.
