The trees are pretty mature. Both trees' span aroud 4-5m at their
widest points, although they're not too dense.

Teehee, when someone asks the diameter they don't mean the whole tree, they
mean the trunk.

You see why I have to ask for advice :-)

Birch is around 15cm in diameter, Hawthorn splits into two 'trunks'
close to the ground, one around 10cm, another a bit less.
