Green-fingered volunteers will join Lancashire Wildlife Trust (LWT) for a planting day in Preston from 11am on Wednesday, June 25.
The event is part of a project to recover and conserve threatened plants in Haslam Park, off Bristow Avenue.
An area of the park has already been landscaped to create a wetland habitat. Seeds have been collected, with emphasis on rare, declining and threatened plants with restricted distribution that are associated with ponds and wetlands.
The seeds have been stored and propagated, and now sufficiently developed, they will be introduced into the wetland habitats created at the park.
Three interpretation boards, describing the work’s aims and objectives, will also be installed. Work is expected to be complete by the end of July.
Funding for the £61,000 project is coming from Preston Council and The Veolia Environmental Trust who have awarded a grant of £49,082 through the Landfill Communities Fund.
Chris Taylor of LWT said: “This is a great opportunity to improve Haslam Park, create new habitat and give a helping hand to some plant species in sharp decline.”
