FLORA AND FAUNA - Not unique to the rest of Britain or Europe but noticeably different.
Butterflies

Butterflies you'll never see on the mainland, strange flies of irridescent sheen and coloured beetles. A shortage of sparrows? Not here, unhappy with EU farmers spraying everything with poison, they've twigged that we are not part of "The European Union", so all the sparrows have come over and found a place where grasshoppers are still abundant - huge green ones too. Egrets stalk the foreshore alongside the oyster catchers, curlew, & puffins. Seagulls adorn every chimneypot. Echium have huge flower stems 15' tall, native to the Canaries they have been wild here since time immoral, as also massive Mexican Cacti whose flower stems exceed 20', there's one in the Forest Road, right now more at home in Arizona.

Palm trees grow like weeds, that is they self-seed in unusual places like Buddleia, many varieties thrive, as do Umbrella plants growing to 12' as they do along the Nile.

There are no snakes, nor squirrels, nor foxes, nor elephants, while rabbits, rats, hedgehogs and hundreds of donkeys enjoy ripe old age. Heartstongue fern self seed in any dark place and fuschias and geraniums become trees due to the absence of frost.

Rudd, carp and perch swarm in the many quarries now disused and full of fresh water. The reservoir is full of trout, and the sea has bream of 5 varieties, sun fish of hundreds of pounds, bass, rays, pollack, turbot, spider crabs and chancres, lobster and crawfish, Octopusses and Sea Horses. Why hasn't it been fished out like everywhere else? The impossibility of trawling due to the extensive reefs, rocks,  and tide rips, means that nature has hung on - massive conger eels lurk in the clear water canyons and caves, it's a divers paradise- and cliff rock climbing is as good as Snowdonia, but topped by thrift and sloes.

Abalone thrive in their farthest from the Equator outpost, here we call 'em Ormers.
