All species of bat and the places they use for shelter or protection are protected under the Conservation of Habitats and Species Regulations 2010, the Wildlife and Countryside Act 1981 (as amended) and the Countryside and Rights of Way Act 2000.
Bats roost within a variety of structures such as buildings, bridges, quarries, mines and trees. They move about according to their varying roost requirements at different times of the year. For this reason you may encounter bats at any stage of a project. Bats and their roosts have legal protection, so are an important consideration in the design, planning and management of a project. (see A Guide to the Survey Seasons)
We tailor the level of survey effort, (use of remote bat detectors, video cameras, number of surveyors and extra survey visits) to match the complexity of each site. We use the latest, full spectrum echolocation recording equipment and digital recordable night vision sights for accuracy and compliance with new survey guidelines. Our cost-effective surveys ensure that sufficient information is submitted to support a planning application. Lack of detail and inaccuracies can lead to considerable time delays.
Treetec offers a number of bat work services, including:
- Inspection of buildings, structures and trees for signs of roosting
- Dusk emergence and dawn re-entry surveys
- Identification of species, population estimates and roost type
- Activity surveys to identify commuting and foraging areas (remote surveys and transects)
Habitat assessment – to determine suitability of sites for bats.
Bat mitigation – roost exclusion, roost creation, erection of bat boxes, capture and release, all carried out under license where necessary.Long-term roost monitoring and habitat management
We also provide specialized tree survey services where bat presence is a concern:
- Arboricultural assessment of trees to determine suitability for bats.
- Aerial climbing surveys for bats in trees by NPTC qualified and bat licensed climbers.
- Use of hydraulic work platforms to survey for bats in bridges, awkward buildings and dangerous trees.
- Inspection of awkward access areas with remote, wireless operated video cameras.
- Tree Hazard Assessment surveys where bat occupation is known or suspected.
- Providing recommendations for remedial works.
- Preparation of Method Statements for tree works with suspected bat presence.
- Undertaking tree works with suspected bat presence.
