Bat Surveys
Bat Surveys
If your project involves roof works, demolition, extensions,
conversions, tree removal or land development, a bat survey may be required
before planning approval.
Our licensed ecologists assess buildings, trees and
surrounding habitat to identify bat roost potential, provide clear
recommendations and help move projects through planning with minimal delay. Bat
surveys commonly begin with a Preliminary Roost Assessment and progress only
where evidence supports further work.
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.
