Surveying Pilot Project

LCSP Partners at the Lincolnshire and Northamptonshire Environment Agency, Chris Extence and Richard Chadd, have developed a new scoring system based on an augmented list of aquatic invertebrates to extend the Riverfly Monitoring Initiative surveying model.

To implement the new system the Lincolnshire Chalk Streams Project with their partners at the Environment Agency have been working with their existing Riverfly volunteers to pilot the project on Lincolnshire's chalk streams.

Existing volunteers were given a days training by Richard Chadd and Chris Extence hosted by the Lincolnshire Chalk Streams Project, first to emphasise the key problems with local rivers, then to demonstrate how the identification of particular invertebrates can highlight issues such as poor water quality, sedimentation and low flows.

The surveying method remains the same, a kick sample is taken at an allocated river section every month by volunteers and invertebrates are collected, numbers estimated and recorded. The list of invertebrates has been extended to 26 from 8 to give a more in depth evaluation of the issues within the river. The 8 key invertebrates on the standard Riverfly Partnership list are included on the new list.
