Many people seem to believe that when you take away a species’ home they will simply find somewhere new to live. But most wildlife require corridors (such as hedgerows or green space) to reach and find new areas where they can survive. Increasingly, as we cut down more trees, woodland and other habitats, wildlife simply has nowhere else to go, resulting in the mass declines in their numbers that we’re seeing today.
The TPO process is an interesting one which can have surprising results.
Nearby land with derelict houses was going under auction. Several developers were making preliminary enquiries to the council to see what they might be able to build there and because of these, the tree preservation officer came to have a look at the site.
There was a mixture of trees from old mixed species (no oaks), established and younger fruit trees and several immature ornamentals. It was the latter which he put preservation orders on because of their potential to grow into "cracking beautiful trees" - his words. One - a copper beech which faces the public highway - was only a few years old. I remember when it was planted. Now ten years old it is indeed a beautiful tree.
