Cleaver Heath Regeneration Project

Nationally, lowland heathland is a well known type of habitat occurring on acid sandy or peaty soils of low fertility. It is characterised by the presence of a range of plant species such as heather, gorse and bracken together with scattered trees such as birch, oak and pine and mosses, lichens and grasses. In prime condition it is also home to a wide range of both vertebrate and invertebrate animals.

Heathland is one of our most threatened habitats and by 1997 Britain had lost 60% of it's lowland heath, mainly to agriculture and construction. Locally on Wirral, heathland is restricted to areas such as Cleaver Heath, Heswall Dales and Thurstaston Common.

Lowland heathland habitats are typically relatively fragile and susceptible to succession by woodland trees or bracken which out compete and smother plants such as heather. At Cleaver Heath, this situation is exacerbated by the fact that the open lowland heathland habitat is surrounded by silver/downy birch dominated woodland with a ground flora dominated by bracken. Management work at Cleaver carried out mainly by volunteers, involves controlling birch, gorse and bracken growth in the areas dominated by heather, so preventing succession to dense scrub and woodland.

In 2019 the possibility of carrying out a heathland regeneration project at Cleaver was discussed with the aim of increasing the overall amount of lowland heath habitat within the reserve. A site of approximately 0.25 hectares in area, covered in gorse, bracken and some birch and with some heather also present was selected for clearing. The plan was to employ specialized contractors to clear gorse, bracken and birch to ground level with machinery within the experimental site and then monitor the regeneration of the heather over time whilst controlling any regrowth of gorse, bracken and birch. To encourage the regrowth of heather after clearing, the additional application of fresh heather seed or heather litter from within the site containing seed would be carried out.

Although at the time, the project was supported by Cheshire Wildlife Trust and Natural England, the onset of the pandemic, together with funding issues, prevented the project from going ahead. However, Wirral Wildlife received a very generous financial gift from Woodchurch High School which has now been used to help fund the project. This was carried out by experienced habitat management contractors at the beginning of February.

After clearing existing vegetation from the selected site, any unwanted regrowth of bracken and gorse occurring during the Spring and Summer will be removed and heather seed from within other areas of the reserve will be collected and applied to the new site during the coming Autumn and Winter months. Regeneration of the heather will be closely monitored and managed by Cheshire Wildlife Trust and Wirral Wildlife volunteer teams.

If successful this project will result in a significant increase in important heath habitat within the reserve.
