You have probably never seen a great crested newt. If you’re in the UK, you’ll usually only hear about them when construction work is halted because they are found at a building site. In the past month alone, relocating these protected animals has caused delays to new roads, a huge rail freight hub, a 1,400-home development and a football club’s state-of-the-art £14m training complex. Even an illegal rave in Norfolk only made the news because it was too close to a protected breeding site.
