A group of dwellings known as the Isle of Wight is situated within the site, and a track, Common Road, leads to it from the northwest.

The bryophyte flora in the site's woodland is rich and includes one of only two Surrey localities for the moss Zygodon conoideus.

Notable plants found in the grassland of Little Bookham Common include southern marsh-orchid (Dactylorhiza praetermissa), pepper-saxifrage (Silaum silaus), spiked sedge (Carex spicata) and adder’s-tongue fern (Ophioglossum vulgatum).

The flora of the site's open water habitats includes three plants which are scarce in Surrey: greater duckweed (Lemna polyrhiza), fat duckweed (Lemna gibba) and thread-leaved water-crowfoot (Ranunculus trichophyllus), while tall-herb fen communities here support two plants which are rare in Surrey, the grass orange foxtail (Alopecurus aequalis) and eared willow (Salix aurita).

Dead oak trees provide habitat for several beetles which are scarce in Surrey including Nemadus colonoides and Aridius nodifer .
