Bodenham Lake: Lugg Wetland Gem - delivering the nutrient management plan

Bodenham Lake: Lugg Wetland Gem - delivering the nutrient management plan

View over Bodenham Lake

Herefordshire Wildlife Trust are thrilled to have secured funding from the Heritage Lottery and European Regional Development Fund for their project at Bodenham Lake nature reserve.

Bodenham Lake has long been a favourite amongst wildlife lovers and this project is set to create a true wildlife haven at this reserve in the heart of the Lugg Valley. Over two years, the project will focus on key aspects of restoration as well as providing more facilities for wildlife watchers of all ages.

Bodenham Lake, formed by the extraction of gravel is the largest water body in Herefordshire. It is crucial for breeding otter and wildfowl. However, the value of Bodenham Lake as a nature reserve is limited by the habitat; aquatic vegetation grows in very small quantities as the Lake is steep sided and extremely deep. The project will address this in a number of ways.

Re-profiling the lake

The project aims to enhance the biodiversity value of the Lake. In 2018 we moved thousands of tonnes of soil to re-profile three steep sided areas of the lake, creating one hectare of shallower banks. In May 2019 we planted 1,600 reed plants (phragmites) in the re-profile areas to create a reedbed, a nationally scarce habitat which supports a wealth of wildlife including many iconic wetland species such as bearded tits, bitterns and reed warblers.

Installing an artificial island and nesting platform

In areas in which it is not financially viable to re-profile, due to the depth of the lake we hope to install 200m2 of floating man-made floating islands, planted with native wetland plant species or lined with gravel for ground nesting bird bio-matrix to provide habitat. The vegetated bio-matrix will improve the aquatic habitat, provide shelter for fish and improve water quality.
Floating 'nesting platforms' provide a predator free area for endangered species such as Lapwing to successfully breed.

Osprey are seen passing over Bodenham Lake as part of their migration every year. There are only 200-250 breeding pairs in the UK, most of which are in Scotland. The combination of the close proximity or the River Lugg and the density of Lakes makes the floodplain of the River Lugg ideal for Osprey. Installing osprey platforms will encourage passing ospreys to nest.

Bird Hides

In addition to the existing bird hide, we have installed a new bird hide, donated by the Herefordshire Ornithological Club, on the other side of the lake. This will enable people to see and enjoy the new habitats we are creating and the species they attract first-hand. The public can also learn about the wildlife of the Lugg Valley through new interpretation and signage around the site and in the bird hide.

For Families & Schools

For younger visitors, a new pond-dipping pool and platform will be created at the reserve which will be available for families and schools to explore pond life at close quarters! 

Schools and WildPlay lake and wetland habitat themed educational sessions will be linked to the national curriculum for KS1 – KS2. Sessions will include pond dipping and other practical wildlife focused activities. Provision of a Teachers pack will include follow up seasonal activities to do at the lake, advice on the creation of wetland habitats in school grounds and advice on long term management. Schools should contact Engagement Manager Katrina Preston for more information on 01432 530088 / k.preston@herefordshirewt.co.uk

Wildlife Surveys

Local volunteer groups will be trained in surveying skills to enable them to survey, monitor and maintain the lakes. The Lugg Living Landscape area has a number of highly invasive species, as part of this project we hope to minimise the threat posed by American signal crayfish and American mink.

If you are interested in joining the survey groups, please contact Sophie Cowling on 01432 356872 / s.cowling@herefordshirewt.co.uk

Events

We want people to be at the heart of our heritage conservation activities and there will be events happening throughout the project for people to find out more about how the project is progressing and enjoy this beautiful site.

A public launch of the project will be held during summer 2017, throughout the project we will run guided walks and in summer 2018 a celebration event.

Please check our Events pages and Facebook page for up to date information.

The next stage of the project - transforming the lake's islands

We are now planning to extend our habitat improvement works to three of the lake’s islands.

We have been awarded £84,164 of European Regional Development Funding towards this and have raised an additional £8,000 through generous donations from our supporters so we can achieve even more for Bodenham's wildlife!

The first stage of the works will be to remove trees from the islands to allow earth works to take place. The islands have not been managed since they were formed in the 1980s resulting in dense cover of willow and alder and sparse ground cover for nesting birds and otter. The plans for islands are as follows:

  • Island 1: Win spoil from the bottom section of the island and add it to the old road that runs underwater to create shallow waters suitable for aquatic plants and wading birds.
  • Island 2: Create three islands of a larger surface area. Two of these islands will be below the water level to allow reedbed to establish. The remaining island will be allowed to scrub up, to provide cover for otter.
  • Island 3: A trench will be dug through the centre of the island to win spoil to create three islands with a larger surface area. These islands will be capped with gravel to create habitat suitable for ground nesting birds. Island 3 is in front of the new bird hide. 

What are the benefits to wildlife?

Islands are vital for nesting birds, as they provide increased levels of protection from land-based predators, improving survival of chicks. Bodenham Lake has five islands equating to 1.75 hectares, providing fantastic potential to conserve species such as oystercatcher and snipe (which are are on the RSPB Amber list as they have experienced a moderate decline of 25-50% in UK breeding population over last 25 years).

Since gravel extraction finished in the 1980’s there has been little ecological management of the islands, allowing them to form immature woodland which is suitable for very few ground nesting bird species; they require good visibility to spot aerial and aquatic predators approaching the nest.

The aim of the re-profiling work is to increase habitat diversity, to support a wider range of species. Removing trees from two and a half out of the five islands will encourage birds such as little ringed ploveroystercatcherlapwing and snipe to nest, helping to conserve these species. Research by the RSPB has shown that several small islands will hold more nesting birds than a single island of the same total area, so we plan to transform three islands into eight.  

The remaining two and a half islands will remain unchanged to support populations such as herons, cormorants and greylag geese.
