Bats frequently roost in trees, with some species solely relying on trees to provide their roosting locations. Aerial inspections enable potential roosting features at height to be closely inspected to assess their suitability to support roosting bats, and look for evidence to indicate if the feature is in use, or has recently been used.  This method provides a safe and cost-effective way to assess potential bat roosts in mature trees, and complies with good practice guidelines. By removing some of the uncertainties associated with purely ground-based surveys, aerial inspections can avoid some of the project risks in terms of time and budget.

 

How Do We Conduct Tree at-Height Bat Inspections?

​

Our team of experienced and licensed bat surveyors and tree climbers utilize a combination of techniques to provide a thorough assessment:

• Ground Level Inspections: Each tree is assessed from the ground using high-powered binoculars. This enables the tree climbers to target only trees in which potential roosting features have been identified. 

• At-Height Tree Inspections: Using specialist climbing equipment, our surveyors meticulously examine trees at height for potential bat entry points, such as cracks, crevices, and woodpecker holes.

• Endoscope Inspections: If necessary, endoscopes are used to look into tight spaces and confirm the presence or absence of bats or bat roost features.

• Identify Bat Signs: Our experts can expertly identify bat droppings, feeding remains, and other subtle signs of roosting activity.
