Nettleton Bottom Quarry

This disused quarry is a Tioxide landfill situated about 30 km from the main site.
A full ecological survey of the site has not yet been carried out but the site is known to have considerable wildlife interest. The following discussion is based mainly on information provided by R. Julier, Environment Department, Tioxide Grimsby.
There are quite extensive grassland areas with finer leaved grasses such as fescues (Festuca spp.) and bents (Agrostis spp.) together with coarser species like cocksfoot (Dactylis glomerata) in places. The herb flora whilst not containing any particularly rare species is nevertheless of interest with the presence of such species as harebell, field scabious, lady’s mantle and bird’s-foot trefoil, the latter being the main food plant of the Common Blue Butterfly. Ploughman’s spikenhard also occurs, which whilst not a rare species it is less common in the north with the Tees marking the edge of its range in Britain (Streeter 1998). (see Table 20)

Insects
Detailed entomological surveys have not yet been carried out at Nettleton Quarry, however, as shown in Table 21, a number of common butterfly species have been recorded.

Birds
Unlike most other Tioxide sites there birds of Nettleton Quarry are poorly recorded. However, Common Pheasant (Phasianus colchicus), Red-legged Partridge (Alectoris rufa), Barn Owl (Tyto alba) and Skylark (Alauda arvensis) are known to occur.
Skylark and Barn Owl are both National Biodiversity Action Plan species in Britain and Barn Owl is of international conservation concern (Tucker et. al. 1994)
