The Derbyshire green space is an area of mixed woodland planting and a wildflower meadow on the site of a former clay pit and brick works.
The grant of £9,000 will be used for new information points, interpretive panels and signage, new seating, planning and establishing flora and fauna surveys to add to national, regional and local databases and conservation and environmental learning and awareness-raising opportunities for the community, especially for young people.
Site owner Derbyshire County Council has trained the friends to be a valuable workforce supporting the council on site.
Cabinet support member for highways, transport and Infrastructure Councillor Trevor Ainsworth, said: "In common with many of our countryside sites Aston Brickyard Plantation is built on land reclaimed from former industrial use and returned to nature for the enjoyment of both residents and visitors.
"We are very grateful to FAB for their commitment to continually enhancing the site which has become an important community resource and a home for a wide range of wildlife.
"Their fundraising success is great news. We congratulate them on this and look forward to working with them to bring about further improvements."
The site was a major gypsum provider in the 18th century, a brick works until mid-1960s, and then a landfill site until the late 1970s when villagers began to plant trees. The site was left wild until 2012 when FAB was formed with council officer guidance.
