3) How many species are native to England? and what are there names?

Its an unknown number. Species are still being discovered in the UK - usually small insects. If you were to attempt to list all the names of species discovered in the UK- plants bacteria fungi fish birds mammals amphibians etc... you'd fill a small book ???
