There are numerous quarries and old industrial sites across the Belfast Hills. Many of these sites have naturally regenerated and are rich in biodiversity. However others are overgrown with scrub, have grasslands that are rank due to lack of cutting or grazing, have invasive species, illegal dumping or draining problems.

Other active industrial sites also exist in the Belfast Hills providing an opportunity to work with site managers to initiate improvements for landscape and biodiversity alike.


To date work has been undertaken on three industrial sites – Black Mountain quarry, Aughrim Quarry and the Limestone quarry Cave Hill.

Staff from the Black Mountain Quarry on the Upper Springfield Road (an active quarry and inert landfill site) as well as staff at Aughrim Quarry on the Flowbog Rd (an inactive quarry and inert landfill), have embraced the opportunity to work with BHP staff and volunteers on a number of biodiversity improvements to the site. This has included survey work, wildflower planting, training course on wildflowers and tree planting.

The Limestone quarry is an inactive/historic quarry. Work has been undertaken with Belfast City Council staff and volunteers to remove invasive species and some scrub. Vegetation has been cut back, and some earth turned over and wildflower seeds planted as a first step to enhancing this sites biodiversity.
