It’s a bit of a tangent to the original question but:
“...my council automatically rejects any TPOs to remove trees in the parish...”
Whilst the text is a bit misleading I’m assuming what it actually means is any application for work to, or removal of, a tree subject to a TPO is automatically rejected.
If that is what is meant, then it is a very poorly considered and ill informed default stance to have adopted.
Having ‘planning’ experience on a PC is rare enough. Having arboricultural experience is about as rare as unicorn tears!
Trees are living organisms with structural and physiological features which need to be understood and applied within the physical environment of the tree.
Any application for work on a tree subject to a TPO requires a supporting justification case - just like any planning application.
If the justification case is plausible it deserves the due consideration of a PC - it’s pretty easy for a competent arboricultural consultant to make, and present, a plausible case if the evidence is there.
I’m not sure if a TPO app objection from a PC generates a 5 day protocol (because I’ve never failed to demonstrate the justification) but if it does it’s a blatant waste of time and effort for all involved just because a PC has adopted a poorly considered blanket policy.
