Established in 2014, RammSanderson provides expert CS38 tree climbing bat surveys.

RammSanderson Ecology provides a comprehensive service including a range of survey techniques for bats. 

Our licensed Bat Ecologists can complete roped access tree assessments to assess features on trees for their potential to support roosting bats, as well as to seek out evidence of bat roosts.

Bat Survey Tree Inspections

Typically, preliminary appraisals and ground-level tree assessments, following the guidelines of the Chartered Institute of Ecology and Environmental Management (CIEEM) and the Bat Conservation Trust (BCT), are used to determine if trees have suitable features for roosting bats when viewed from ground level.  

However, these ground-level surveys can be limited. Despite best efforts using torches and binoculars, features such as branch collar rot holes can, from the ground, appear to offer suitability for bats triggering the need for nocturnal surveys. 

Our qualified CS38 tree climbing team holds Natural England Bat Survey licences which allows us to undertake more in-depth, at-height assessments of trees for their potential to support roosting bats.

Efficient Bat Mitigation Tree Inspections 

With our CS38 tree climbing service, we can climb trees for close-range inspections. This allows us to rule out unsustainable roosting features, eliminating the need for additional nocturnal surveys, which are limited to the active survey window from May to September.  

By climbing trees, any features identified from the ground can be closely visually inspected and where necessary an endoscope survey can be performed to confirm suitability or the presence of a roost.

Our CS38 tree climbing team undertakes surveys at any time of the year, removing potential delays to a project. Roped assessments can efficiently identify trees as having negligible potential for roosting bats by being able to closely inspect features.

This service also enables RammSanderson to undertake mitigation projects under the European Protected Species Licence for bats by fitting features such as bat exclusion devices, as well as installing compensatory bat boxes within trees.

Tree climbing is a cost-effective way to survey multiple trees - between 6 and 10 trees can be climbed in a single day. 

Where these trees are discounted from the need for a nocturnal survey, clients can make significant savings in comparison to nocturnal surveys which require multiple separate visits per tree.
