Clay Mills, Egginton and Wetmore 58 A Biodiversity Audit of the Tame & Trent River Valleys in Staffordshire (including the Central Rivers Initiative and Tame Valley Wetlands Project areas) 2006-7 Site (1) Clay Mills, Egginton and Wetmore Area 359 Hectares Ownership Severn Trent Water, Forge Poultry Farm, Wetmore Hall Farm, Meadows Farm, Bass Brewers, East Staffordshire Borough Council (ESBC) Overview This site is situated at the confluence of the River Dove and the River Trent. It is also an important location as it links DWT’s Repton Nature Reserve with other key sites in the Trent valley. Recommendations Surveys and feasibility studies need to be carried out at STW’s Clay Mills site. EA’s LIDAR information together with soil samples, test pits, dipwells and bathometric information for the lagoons would help inform a re-wetting project which could help create new areas of marshy grassland and encourage the expansion of reedswamp and wet woodland habitats. (STW, EA, SWT). Clay Mills Sewage Treatment Works is due to be upgraded. Tertiary treatment using the lagoons to “polish” the effluent is to be discontinued. There is an opportunity to link the smallest lagoon to the River Trent . Spoil from the wetland creation works at the northern end of the site, instead of being removed from the 1:100 year floodplain, could be placed into the margins of the lagoons. This would help create a major area of reedbed in both lagoons. It is also recommended that STW purchase the additional land between the Trent at Dove opposite Newton Solney. This comprises of good quality marshy grassland and an area of wet woodland. Funding for this scheme should be sought through AMP5 (bids to OFWAT in 2007) and/or through the EA’s flood risk management programme. (STW, EA, OFWAT, SWT). Additional opportunites are available for a re-wetting project at Meadows Farm using a drain that runs north-west from the National Forest tender scheme area. The scheme could provide good habitat conditions for lapwing which are currently breeding on arable land across the river on the Wetmore Farm estate. (NE, FWAG, SWT, NFC, landowner). Comments Further recommendations and plans have been produced by SWT for STW. The site has been divided up into compartments with target notes. Middlemarch Environmental has also assessed the site in the past and identified opportunities.

Protect veteran trees and existing dead wood. Retain and manage hedgerows. Repair fencing along River Dove buffer strip and monitor invertebrates. Protect and monitor sand martin colonies. 60 A Biodiversity Audit of the Tame & Trent River Valleys in Staffordshire (including the Central Rivers Initiative and Tame Valley Wetlands Project areas) 2006-7 View of treated effluent from Clay Mills STW entering the River Trent near Newton Solney.

Taken together, these sites provide a strategically important green corridor through the centre of Burton-upon-Trent. It is multi-functional in that it provides space for water during floods, amenity areas for public enjoyment and habitats for a host of wildlife from dragonflies to otters. Recommendations Secure a copy of the report produced for ESBC by the Wildfowl & Wetlands Advisory Service in 2003. (ESBC, EA, SWT.) Treat, remove and monitor the stand of Japanese knotweed located at the NW part of site close to the main entrance (ESBC, EA). Undertake major re-profiling project of the inside of the main meander on the River Trent at this site (approximately 6000 cubic metres of spoil). A Land Drainage Consent will be required and, almost certainly, a full planning application (- check with ESBC Planning Department). Remove all topsoil and ‘fines’ from the 1:100 year indicative flood plain. As part of Land Drainage Consent, seek permission to re-position the larger accumulations of gravels back into river to create important spawning habitats for fish off the ‘toe’ of the newly re-profiled meander. This work has been carried out at a number of locations in the Upper Trent Catchment from the mid-1990s and has been, in most cases, extremely successful at kickstarting natural geomorphological processes including the formation of exposed and submerged gravel shoals. The work also helps to increase the capacity of the river channel by approximately one third and so thus does not contribute to an additional flood risk. (EA, ESBC, SWT). Continue the good works undertaken by ESBC and EA (2003-2006). Identify sections where water levels can be raised or impeded. Create additional scrapes, pools, ox bows, ‘dragonfly’ ponds along the existing ditch networks. Undertake further checks to identify land drains left in from former agricultural use. These drains can be selectively blocked or broken open to help feed individual scrapes and pools or to increase dampness in the meadows. (ESBC, EA, SWT, NFC). The large area of amenity grassland at the NE part of the site could be managed to increase species richness. Advice from SWT and Prof. Truman (formerly Wolverhampton University) could be provided to trial reverting the grassland to a traditionally managed hay meadow. (ESBC, SWT, NFC). The grasslands at the southern end of the site should be grazed lightly with a rare breed (Dexter, Belted Galloway, Gloucester). Additional sporadic grazing of other parts of the site (including the wetlands and woodland edges would also be desirable. Monitor effects on vegetation and key species). (ESBC). Explore the option to notify Upper Mills Farm as a Local Nature Reserve (LNR). (ESBC). Comments Good site for scrub-loving birds, especially breeding warblers (including lesser whitethroat). Retain mature hedgerows throughout the site. 63 A Biodiversity Audit of the Tame & Trent River Valleys in Staffordshire (including the Central Rivers Initiative and Tame Valley Wetlands Project areas) 2006-7 Treat and remove Japanese Knotweed at the entrance to the site. Consider ditch re-profiling, raised water levels, on-line ponds and further scrapes adjacent to the main car park. View of scrapes and wetland areas created circa. 2002. 64 A Biodiversity Audit of the Tame & Trent River Valleys in Staffordshire (including the Central Rivers Initiative and Tame Valley Wetlands Project areas) 2006-7 Maintain hedgerows and areas of scrub for breeding warblers (including lesser whitethroat). Re-profile the inside of the main meander along the River Trent. A potential deposition site for spoil from the re-profiling project. 65 A Biodiversity Audit of the Tame & Trent River Valleys in Staffordshire (including the Central Rivers Initiative and Tame Valley Wetlands Project areas) 2006-7 Annotated map for Site 3: Branston & Drakelow 66 A Biodiversity Audit of the Tame & Trent River Valleys in Staffordshire (including the Central Rivers Initiative and Tame Valley Wetlands Project areas) 2006-7 Site (3) Branston & Drakelow Area 114 Hectares Ownership East Staffordshire Borough Council (ESBC), Derbyshire Wildlife Trust (DWT), Branston Properties Partnership Overview The Trent floodplain has been squeezed by the railway and the infilling of the former Branston gravel pit with Pulverised Fuel Ash (PFA). Currently, some water can back up during major floods into the land to the west of railway line via a minor brook course (the ‘Branston’ Brook) and two culverts. However, this land is not considered to be part of the Trent floodplain, but it has been subject of two recent planning applications for it to be developed to a combination of housing and light industry (these were withdrawn in April and October 2005, but may well be re-submitted). There are a number of issues and concerns here including: (1) The grassland area to the west of the railway earmarked for development is currently one of the main strongholds for breeding skylarks (Staffs BAP species) in the project area, (2) The area is a former part of the main River Trent floodplain, but retains important links through the ‘Branston’ Brook corridor. Part of this area would be better used as a washland and engineered to store water during major floods, (3) the Branston Brook is an important corridor for otters moving between the two potential breeding sites at Branston Water Park and Drakelow Nature Reserve.
