In the past, the Hill was covered by heather and low-standing gorse. Its poor soil supported few trees. However, during the last 50 years and owing to a variety of factors, invasive non-native species of flora have been taking over the hill. This process has narrowed or hidden paths, considerably reduced the heathland flora and obstructed many view sight-lines. The Memorial Garden laid out in front of the memorial has completely disappeared under bushes and coarse grass.
The Friends of Grange Hill group has been formed to try and reverse the decline. Its first task will be to restore the Memorial Gardens but this will also require the improvement of access by work on some of the paths. To avoid disturbing wildlife, most of the work will be done from late autumn to early spring. In the longer term, many of the trees on the summit need to be felled and large areas of gorse and bracken need to be cut back. A full inspection of the site has been made with the rangers to identify plants and trees which harbour protected species, such as bats, which must not be disturbed by any work done.
Regularly seen are Blackbird, Song Thrush, Goldfinch, Greenfinch, Chaffinch and Bullfinch. Robin, Wren, Great and Blue Tit, Linnet and Dunnock. Kestrel regularly hover overhead.
Passage migrant and seasonal species include Chiffchaff, Willow Warbler, and Whitethroat which arrive in the Spring. Wheatear, pass through and can be spotted in the cemetery where they stop for a rest on headstones. Swallows, House Martin and Swift can be seen gathering at the end of summer before they depart for warmer climes.
Many birds are seen over the hill as they move from the estuary to the fields and ponds inland (Hoylake Lang fields & Gilroy Nature Reserve) and vice versa morning and evening. These include Canada Geese and a variety of ducks and waders.
Occasionally Tawny Owl, Common Snipe and Pheasant can be seen and more commonly heard.
This list claims to be neither exhaustive nor comprehensive, merely an indication of what may be encountered on the hill.
