Cavenham Heath National Nature Reserve is a Site of Special Scientific Interest (SSSI) and is on Open Access Land managed by Natural England. The site has habitats of heath, grassland, woodland, wetland and areas of fen. The 204 hectares is home to a wide variety of bird species. Of particular interest are the breeding Stone Curlew which in autumn, can be seen in pre-migration gatherings numbering over 100 birds before heading south for winter. There are good numbers of rare and scarce plant species too, many species of butterfly and over 400 species of moth recorded on site.

TTSR Ltd were contracted for excavation works to expose subsoil in three particular areas, forming high banks for Rabbit habitats. These banks, built with south-facing orientation—so that they are in full sunlight—allow the rabbits to build warrens in the sandy heath; to protect and sustain the species. The presence of the Rabbits and the way they graze allows for small heathland plants to grow, that often cannot survive in other areas. These, in turn, attract and support the spread of other small creatures, including Stone Curlews – which is another Natural England Biodiversity Action Plan (BAP) target species – as they like the short grass sward that Rabbits create.

The bottom of the trench is dug unevenly to provide many north, south, east, west microclimates. Other insects and species of moths and butterflies, some of which are threatened with extinction, particularly benefit from this.
