1 Heol-y-pavin Llandaff Cardiff CF5 2EG

Removal of 2 trees. 1 x Beech (we think its a common Beech) 1 x Purging Buckthorn (we think it's this species). The Beech is hard against an old historic wall in Llandaff Village. Currently the tree height is low and the trunk is small. But we believe Beech can grow up to 40 meters and have a trunk diameter of up to 1.5 meters. This tree when fully grown would almost certainly damage the historic wall and possible a drain/manhole/sewerage pipes which are within 2 meters. Additionally, the tree would be far too large for the small cottage garden that exists. Our proposal would be to remove this tree and plant another away from the wall and of a size that is proportionate to the small cottage garden. The other tree is also hard against the same wall and an outbuilding which is causing damage. Its current position means it can't be easily seen. Its also overgrown with Ivy, dead in parts and possibly dying as a tree. We are proposing to remove this tree and plant another in a location where it can be seen, where there is better light and where it can't damage property.
