I agree we should endevour to protect the native species of our isles.
But also we need to be realistic and in some cases accept that we can't fight the inevitable, accept that some species may be unable to survive if our climate changes, Target our resources in areas where we can realisticaly make a difference and towards species that will thrive in a slightly warmer climate. Salmon in our southern rivers particularly may just have to be a casualty of climate change.
There will be some tough decisions to be made. I hope those that are involved in the decision making process have the strength and conviction to make the right ones.
