About the Project
The project aims to restore up to 200 hectares of limestone grassland; a priority UK Biodiversity Action Plan (BAP) habitat.
This habitat on Portland is of international importance supporting ten UK BAP species, including the unique 'cretaceous' form of the silver studded blue butterfly which now only survives on the island.
Hundreds of species of plants and animals are dependent upon the limestone grasslands and coastal habitats of Portland for their survival. These include 27 species of National Scarce, Rare or Vulnerable plants and an incredible 99 species of Notable or Red Data Book invertebrates. In addition to the more visible species over 350 species of lichens and bryophytes have been recorded, 23 of which are on the UK Biodiversity Action Plan Red List.
Cotoneaster growth is currently the biggest threat to limestone grassland on Portland. Without intervention we will see the local, and in some cases global, extinction of a number of species.
While Buddleia plays an important part in the life cycle of some butterflies, the specific butterfly species that are rare to Portland have a far greater dependency on the limestone grassland plants. Large amounts of Buddleia are a threat to this habitat and by managing the buddleia on these sites we aim to restore this nationally important habitat.

How the project is funded
This very important work has been made possible thanks to a major grant from Viridor Credits Environmental Company through the Landfill Communities Fund (formerly the Landfill Tax Credit Scheme) in celebration of their tenth anniversary.
Landowners and Partners
Under the Portland Living Landscapes Project, management is being carried out on sites owned or leased by a variety of groups including Albion Stone, Portland Stone Firms, Weymouth and Portland Borough Council, Plantlife, Butterfly Conservation and Portland Court Leet. This joined up working is enabling the Project to tackle the issue of invasive species on a landscape scale.

Interesting statistics have arisen from many aspects of the Portland Living Landscape work. This video explores the biomass burden of Cotoneaster horizontalis on one of the more sensitive areas.
