Suppliers will also obtain protected species licences and provide survey data in GIS-compatible formats to TfL and Greenspace Information for Greater London. Vegetation clearance and treatment are outside scope.

The requirement calls for appropriate professional memberships, such as the Chartered Institute of Ecology and Environmental Management or the Arboricultural Association, together with relevant professional qualifications and protected species licences. Suppliers need reliable survey, inspection and data-assurance processes, GIS-compatible data capability, and the ability to provide TfL full access to and ownership of collected inspection and ecological data. Staff working in the track environment require London Underground certifications, including a Sentinel Card with ICI-LUL endorsement, alongside robust safety practices for hazardous environments.
