Plant List for Oldbury Power Station

First of all, I must recommend the following website, which I have used extensively for identifying many difficult plants -


(All photos taken at OPS.)


There is also a List of Animals for the site, and a List of Insects.


Total number of species (all genuses) reported at OPS = 1175 (372 Plants & Fungi, 404 Insects, 142 Animals/Fish, 257 Birds (inc. escapes)).
