Plans to turn the former Cronton Colliery site in Merseyside into a nature park for wildflowers and animals is to be considered by councillors.
The colliery, which closed in 1984, could be transformed into a 43 hectare haven if plans are approved by Knowsley Metropolitan Borough Council.
The Land Restoration Trust is to submit plans to the council on Monday along with comments from nearby residents.
The trust proposes to improve access to the site if the project is agreed.
A series of bridleways, cycle and footpaths would be created together with a link between Whiston and Huyton along the disused mineral railway line.
