River Condition Assessments

Need to calculate the biodiversity net gain of a development project which effects rivers? Or are you a consenting body or landowner that needs to calculate biodiversity losses and gains for riverine habitats? We can help!

Biodiversity net gain is calculated using the accounting tool Biodiversity Metric 3.0, the metric that underpins the Environment Bill’s provisions for mandatory biodiversity net gain in England. A component of the biodiversity metric is the River Condition Assessment. A River Condition Assessment includes two components: (1) The MoRPh field survey and (2) The River Type desk study. These elements are combined to assess the river condition, where values are generated which can then be inputted into the Biodiversity Metric 3.0 spreadsheet to calculate net gain.
