Tree climbing bat surveys
We have a team of bat licensed tree climbers at hand to survey trees for bat roosts.

Following a preliminary inspection from the ground, our tree climbing team can carry out detailed inspections of roost features within trees, that would otherwise be inaccessible. They are well versed in recognising signs of bat usage in trees, and will evaluate each feature according to its potential for a bat to use it to roost there.

Bats can roost in a variety of features within a tree including cavities, splits and tear outs, woodpecker holes, and knots as well as lifting and flaking bark. Some of these potential roost features can be examined using an endoscope. Further surveys of features may be required such as presence/absence surveys (dusk emergence / dawn re-entry).

We also regularly check bat boxes as part of on-going mitigation works.
