We have a wealth of experience in assessing the ecological status of ponds and we have an active research group studying methods of pond restoration

Farm ponds

Our work in particular includes the restoration of overgrown and terrestrialised farm ponds and the provision of advice on biodiversity management to local stakeholders. Research in East Anglia is showing that old, neglected farmland ponds, can be restored by partial sediment removal and clearance of surrounding scrub to improve light and sediment conditions making ponds more suitable for the development of aquatic plants.

Even ponds that have disappeared completely from the landscape can be re-located and excavated to create new ponds that are rapidly colonised by plants and animals. We have been involved in restoring a number of these so-called 'Ghost ponds'.

Urban lakes and ponds

ENSIS also has worked widely in urban ponds and lakes undertaking surveys and devising and implementing post restoration monitoring programmes. We can produce management reports highlighting actions to improve water quality and enhance the biodiversity of urban lakes and ponds.

Estate ponds and ornamental lakes

ENSIS has a long track record working on ornamental lakes and ponds associated with country estates. Past projects have had both a contemporary (including surveys and monitoring) and historical (palaeoecological studies) focus.
