Project: Turning a colliery in Merseyside into a park
Client: Land Restoration Trust
Contractor: Waste & Resources Action Programme (WRAP)/Baldwin Landscaping
The former Cronton Colliery site in the borough of Knowsley in Merseyside has been undergoing a redevelopment that will see it transformed into a country park for the region.
The Land Restoration Trust commissioned consultant TEP to prepare a land-restoration strategy for the site, using PAS 100 green compost to restore the areas left unvegetated from previous restorations.
Former bare areas of spoil had revegetated with creeping bent and the site had developed a semi-natural character, which the trust did not want to destroy by taking an interventionist approach.
Under WRAP's trials, PAS 100 green compost was incorporated within the spoil surface to establish a wildflower grassland sward on a permanent basis. One of the challenges was to add enough green compost to establish a permanent sward without encouraging the growth of damaging weeds.
An initial soil survey was carried out by Ecological Restoration Consultants in 2007. The project then required a 30mm layer of PAS 100 compost to be incorporated into the top 120mm of spoil with a wildflower and grass seed mix.
The work was carried out by Baldwin Landscaping with compost from White Moss Horticulture.
The main contract is expected to begin on site this year with the aim of opening the site to the public in 2010.
