We have a few very old large Willow trees on our farm land. DH wants to cut them down to 10ftish and pollard them in future. Reason given, they are in the way (between two fields) and could potentially become dangerous and destroy fencing.
To me it is sacrilege as they are a haven for wildlife with many nesting species particularly owls and can be seen across the rather flat landscape of the area.
I have tried to discuss a compromise such as only removing a third of their height and pollarding but DH is insistent (rather aggressively) that they will be coming down.
We own the land jointly and besides trying to get a TPO discreetly I have no idea where to go from here. Utterly heartbroken he feels the need to be so destructive. I still recall how he cut down a 25ft Holly tree at a previous property 25years ago. 
Suggestions please as this is causing severe marital disharmony. He is currently sulking after a very heated discussion.
