I have spoken in the past about the ecosystem impact that wolves can have, creating what is called a landscape of fear.
The threat of being hunted means that prey change their behaviour far more more than simply the effect of direct predation.
A few weeks ago the British newspaper the guardian, wrote on this subject. I include a link below.
This is a highly important Ecological concept. It has started to be recognized around the world, and many countries have been reintroducing predators to reserves, from which they were eliminated, sometimes centuries ago. This work is essential, and from Yellowstone and the return of the wolves to reserves across Africa and Asia the same is seen.
When will the government recognize this fact of nature, and do something similar in the UK?
