A project to stop rare wildlife being destroyed by invasive plant species has been launched in Dorset.
Dorset Wildlife Trust has been given £850,000 for its Portland in Peril scheme to tackle the spread of species such as cotoneaster and giant buddleja.
The plants crowd out habitat used by butterflies like the common blue, adonis blue and chalk hill blue.
The money was awarded by Viridor Credits which distributes funds from the landfill tax.
John Clode from the trust said it was important to remove the cotoneaster which “grew like a carpet” across the rocks, displacing the natural limestone grassland.
