Ariel Tree Inspections

Aerial tree surveys provide a close inspection of trees with potential bat roost features to determine whether roosting bats or supporting evidence may be present.

Following an initial ground assessment, ecologists inspect cavities, splits, loose bark and other accessible features using climbing techniques, rope access or elevated platforms to provide a more reliable assessment and reduce unnecessary follow-up survey work where appropriate. 

These inspections allow a detailed assessment of features that are often hidden or inaccessible from the ground, giving a more accurate understanding of roost suitability and presence/absence of bats. Inspection tools such as endoscopes and high‑powered torches are used at height to look inside features and gather hard evidence without the need for nocturnal surveys in many cases.

Aerial tree inspections are particularly useful where trees with Potential Roost Features (PRFs) have been identified and where works (such as tree removal or construction) could disturb bats or their roost sites. These surveys help to fulfil planning requirements, guide mitigation measures, and inform whether further surveys or licensing are required.Aerial tree surveys provide a close inspection of trees with potential bat roost features to determine whether roosting bats or supporting evidence may be present.
