The Seven Lochs Wetland Park is situated in a greenbelt area between the urban districts of Millerston and Easterhouse in Glasgow, and Stepps, Glenboig and Coatbridge in North Lanarkshire.
The ambitious project will contain five nature reserves, Iron Age archaeological sites, Provan Hall (one of Glasgow's oldest buildings) and locally protected lochs, wetlands and woodlands.
Fresh visitor facilities will be created, and a variety of activities are being planned to help people learn more about the area's heritage while also having a good time.
Scott Ferguson, development officer with Glasgow and Clyde Valley Green network partnership, said: "This HLF award is fantastic news for the Seven Lochs area. It recognizes it is a great place for heritage and wildlife and that the area should be protected and improved so more people can enjoy and learn about it."
Colin McLean, head of the Heritage Lottery Fund in Scotland, expressed an equally enthusiastic view of the project. "HLF is delighted to help move the Seven Lochs project forward as it brings real cohesion to the natural and built heritage of the region, reconnecting people with the natural heritage which, for many, lies overlooked on the doorstep," McLean said.
The HLF is responsible for distributing a share of the funds raised by UK National Lottery Good Causes. HLF grants are awarded to projects designed to sustain and transform the British heritage.
