A Few Questions About Human Intervention.

The Great Fen project and similar schemes may well be an opportunity to sit back and see what happens if you let things go and manage themselves (though we are probably too impatient a species to let that happen as it could take over a hundred years or more for the ecological communities to stabilise into something resembling a natural ecosystem)

Hi

I certainly believe habitat improvement backed by continued management is the best way forward for protecting specialist species and I also think the Great Fen project is an exciting model to be applauded. But aren't the fens the result of mans intervention and unless the sea barriers are continued to be managed and water levels controlled will they not be reclaimed by the sea?

Going back to the original question I agree with Gill that mans control of hbitat has probably decreased diversity as only those that can fit into our managed habitat can survive.

Should we continue to feed the birds I would say yes as I enjoy the impact of increased numbers.
