Bat surveys are normally undertaken in two stages

Preliminary Ecological Appraisal / Bat Risk Assessment 

Firstly our experienced ecological consultants will undertake a Preliminary Ecological Appraisal for bats at your site. This type of survey is also frequently referred to as a bat scoping survey, phase 1 bat survey, daytime bat inspection survey or simply a bat assessment.

This entry level survey can be carried out at any time of year and is conducted during daylight hours. Our ecologists will assess any built structures, trees and landscape features onsite for bat roosting and foraging potential or dependent on the time of year actual evidence of bat occupation may be visible.

Emergence and Re-entry Surveys

If habitat suitability is confirmed or evidence of bat presence has been identified during the Preliminary Ecological Appraisal for bats our ecological consultants will arrange to revisit your site to conduct a bat emergence survey, otherwise frequently referred to as a bat dusk and dawn survey or phase 2 bat survey.

This survey will be conducted at dusk and dawn during the months May to September. Our ecologists will observe bat behaviour in and around your development area and identify any bat emergence or re-entry at roost locations, plus identify which species of bat(s) are present and the number.
