It’s Our Cornwall has raised an interesting topic:-
Here’s a puzzle. Why do developers always claim their projects will ‘enhance the biodiversity’ of every site they build on? Yet the Council’s own Sustainability Appraisal of its Local Plan concluded that housing and ‘development’ has a ‘direct negative impact on biodiversity’, while ‘increased growth will have a detrimental impact upon biodiversity’.
Yes it is rather odd to suggest that more housing raised biodiversity. For one thing there is the impact on the land itself and development by its very nature leads to resource use and therefore loss of biodiversity elsewhere.
It has been claimed that farmland which is planned for development does not always score highly on the biodiversity index. But low diversity farmland is a consequence of poor management which should be remedied by policies to increase biodiversity – not by building on it!
