Bat survey of a tree in Rotherham South Yorkshire

Today I completed a bat survey of a tree in Rotherham South Yorkshire. The tree is to be felled for a housing development. The climbed inspection was a condition of planning, as the tree had features which could be used by roosting bats. No field signs of bats, or potential roost sites were found, and so the tree can be felled.

Survey details

I inspected the tree from the ground. To find any suitable features, and identify the places I would need to climb to and inspect, I used binoculars and a high powered torch. To. When I had inspected all of the holes from the ground, I made a plan of how to safely climb the tree.

Trees can be climbed using ladders, but a better, and safer way is to use ropes. I am trained to use ropes  to climb trees. This allows me to get to places you can’t with ladders. And without needing to hire an elevated work platform, or crane, which can be expensive.

All of the holes which were spotted from the ground were accessed and inspected using an endoscope. A lot of the features which look viable from the ground, are not suitable for roosting bats. Because the hole is too small, or too exposed to be used. The details of these features are then provided in a report for the local planning authority.


The tree needs to be taken down, for safety reasons as it is in a has lots of dead, and rotten branches in the crown, and decay in the trunk. Which indicate that it is in poor condition, and could fall. As the tree is on the edge of a new housing development, it poses a risk to people and property.

The inspection found no evidence of use by roosting bats.  And no suitable cavities. I produced a report for the client. So that the planning authority could discharge the planning condition. This allowed the tree to be felled.  and allowed work to continue on the site, without the risk of the tree collapsing.

Aerial inspection of trees can save money, and time, by ruling out features in trees, which look viable from the ground. It is a quick, and relatively cheap way of protecting bats, and enabling works to go on.
