Tree Climbing

Bat Tree Climbing Inspections

Darwin Ecology have a number of licensed bat ecologists, trained in aerial rescue and with specific training in inspecting trees for bats. 

These surveys are undertaken using an endoscope to confirm the presence or absence of bats. Tree climbing surveys can be undertaken at any time of year. From these surveys, trees will then be assigned to one of the following categories:
  • No suitable features - features found to be unsuitable for bats e.g holes too shallow and exposed, holes open to water ingress. Tree downgraded to Category 2 or 3 and remedial works can continue with caution.
  • Features have some bat potential but no signs found - consider if signs could have been obscured by weather/other animals. Further emergence survey work may be necessary to establish use in other seasons. If holes have been inspected to their full extent and are not being used by any wildlife they can be blocked with excludes prior to felling to prevent use.
  • Features have very good bat potential/could not be investigated to their full extent - emergence surveys required to confirm likely absence/seasonal use.
  • Feature is confirmed bat roost - bat signs or bats found. Level of roost should be assessed, species, seasonality, frequency of use and numbers. Emergence surveys required to gather more data. Tree will require EPS license to undertake remedial works or felling. 

Reporting



Upon completion of the field survey, a report will be produced, which will include details of the survey findings and recommendations for mitigation and enhancements that will be required in order to implement the developmental proposals
