please help these leaning trees...

... even thought they are Leylandii!!

They were planted to make a very tall screen in one of our fields.

Now as you can see in the photo some of them are leaning at precipitous angles although they seem otherwise healthy. The bamboo pole indicates vertical.

There seem to be many possible causes  heavy snowfall a few months ago, rabbits & other mammals leaning on the base of the trunks to get to the bark higher up, and a rabbit warren undermining the root system. It could be a combination of all three.

The trees seem to have grown in this position for some time because they resist being pulled upright.

What would you do in this situation???

In the English midlands here.
