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 = 902 (290 Plants, 226 Insects, 134 Animals/Fish, 252 Birds (inc. escapes)).
