Ecology Link was commissioned by CH2M Hill to undertake a specialist invertebrate assessment of water channels within Lincolnshire.

Provide baseline invertebrate data

Aquatic macro-invertebrate surveys were undertaken to assess the faunal assemblage of a series of drains that were connected to the South Forty Foot Drain and a section of the River Glen. The aim was to provide baseline invertebrate data for the watercourses, which fed into the wider Impact Assessment for the project. This sought to provide navigation links between the River Glen through the South Forty Foot Drain to the confluence with the River Welland.

A total of 15 sampling areas were identified, 11 points on connecting drains of the South Forty Foot Drain and four on the River Glen. Aquatic macro-invertebrates were identified to species level where practicably possible, with relative abundances of each taxon being provided.

140 macro-invertebrate species recorded

The initial survey was undertaken in September 2013. A total of 140 macro-invertebrate species were recorded from the 15 survey sites. Three species were Nationally Scarce, two were considered as regionally notable and 25 species considered local in distribution.
