Advanced survey effort required to obtain bat assemblage data in temperate woodlands (Chiroptera)

There is a lack of precise guidelines concerning the survey effort required for advanced bat surveys in temperate European woodlands, resulting standardisation methods. In this study we assess catch data from 56 trapping at 11 UK woodland sites order to provide recommendations mist net gain meaningful assemblage woodlands. Species accumulation curves were produced and used develop two novel values effort: minimum threshold (MST), whereby surveyors are more likely than not encounter less dominant species; known species (KST), point where given percentage (in our case, 75%) site be reached beyond which there diminishing returns effort. For data, mean MST was 17.4 hours, KST, 29.8 hours. The KST during second third surveys, respectively. These proposed adaptable based on location may planning woodlands only maximise efficacy use limited resources but ensure ethical viability undertaking first place.
