To the left you can see our Tree Surgeon whilst at work in a large Beech tree. (He is the tiny white figure in the centre of the photo!)
This particular tree is well over 100foot tall, and is a very mature tree. And although it's almost impossible to see, the tree canopy was entangled with radio transmitter wires and so our surgeon had to ensure none of the receiving equipment was damaged during work on the tree by either himself or by debris being removed.

This photograph is the same as above but we have zoomed in to give a (slightly) clearer view of our man!

You can also judge better the size of this tree as you can make out the circumfrance of the tree trunk, giving you some perspective!
