Back Burn River Restoration Plan

TEP and the River Restoration Centre collaborated in a river restoration study for the Back Burn, in Fife. The burn runs through scenic countryside and urban fringes of Glenrothes, but is a “Heavily Modified Waterbody”, requiring restoration under the Water Framework Directive.

The section of burn is about 7km, and has been subject to culverting and diversion resulting in channel habitat loss and disconnection from the floodplain. Much of the burn has reinforced banks, which along with over 20 weirs, means that there are many barriers to fish migration.

The aim of the project was to prepare a holistic river restoration plan, which considered aquatic and terrestrial ecology, access improvements, greenspace and community projects and how to enhance ecosystem services.  Driven by the need to achieve “Good Ecological Potential”, the clients’ other objectives were to bring biodiversity and community benefits to Glenrothes.

Our first steps were to define seven distinct reaches and carry out hydrogeomorphological studies to assess the degree of bank and channel modification and identify and map barriers to fish movement. Constraints were mapped, including utilities, urban infrastructure and features of high ecological or amenity interest. Five of the seven reaches were identified as “upgrade” reaches, while 2 were so severely constrained that full upgrade to GEP was not feasible at reasonable cost.

We prepared a costed options plan, listing multiple benefits to allow the client (Scottish Environment Protection Agency and Fife Council) to make an options appraisal and determine the most appropriate restoration plan. For example, one of the recommended options was the restoration of a paleo-channel and creation of a step-pool sequence at Coul Den, where the natural course of the burn was fragmented by the creation of a reservoir and a bypass channel to serve a now-closed whisky distillery.

We also carried out a phase 1 habitat survey of the Back Burn corridor, mapping habitats that could contribute to Fife’s Local Biodiversity Action Plan priorities. We prepared a costed project list, identifying which ecosystem services would be enhanced.

A novel innovation was our “Ecosystem Services Opportunity Map” which is available as an interactive webmap. Each land parcel is scored in terms of whether it could be managed to increase ecosystem functioning in relation to the following services: water quality, leisure and recreation, biodiversity, carbon sequestration, flood risk management, air quality. Parcels with most potential for enhancement are highlighted on a “heat-map” of the Back Burn corridor.

We also carried out a greenspace audit, using Green Flag criteria and a path quality survey. These assessments generated a costed project plan with measures for improving access, interpretation, and community engagement.

The study will lead to funding from SEPA’s Water Environment Fund for implementation of river restoration and greenspace improvement measures.
