Our Green and Pleasant Land series has exposed worrying declines in the natural world across the UK. But what about in your back garden? Check out the interactive graphic.
On the other hand, some species are gaining ground as climate change makes the UK a more hospitable homeland. Otters, polecats and dragonflies have all seen significant recent boosts.
