Bat Surveys
Bat Surveys
All species of bat, their breeding sites and resting places are strictly protected in England by European and UK legislation.
If you’re applying for planning permission to develop or carry out building work that might disrupt a habitat for bats, you will be required to produce a bat survey.
Survey Methods
The type of survey you require will depend on the type of development. We have one set of surveys that cover buildings, structures and underground sites, and another for trees. We can advise on this to ensure that we undertake the correct survey to meet your planning obligations.
Preliminary Roost Assessment (PRA)
A PRA will involve an initial assessment of the site to look for potential to support bat roosts. It can be carried out at any time of the year. Bats commonly roost in buildings and trees so any buildings or trees that may be impacted by works are assessed internally and externally for evidence of bats and potential roosting features If it involves inspecting trees, the best time is December to March when leaves are absent.
Emergence/Re-entry
If the initial assessment identifies the existence or potential for roosts further surveys will normally be required. emergence surveys must be undertaken between May to September. Multiple visits may be required to determine the presence of roosts.
Fish Surveys and Fish Rescue
Safely capture and relocate fish before work to protect aquatic life and habitats.
Protected Species Surveys
Serve to detect legally protected wildlife before works to inform planning.
Biodiversity Net Gain
Quantify habitat losses and gains to secure an uplift in biodiversity.
Invasive Species Surveys
Map and ID non‑native plants to guide land management & protect biodiversity.
River Condition Assessments
Assess river habitat to understand condition and guide restoration.
