Abstract

The use of acoustics has not previously been assessed as a tool for the large-scale monitoring of small terrestrial mammals (excluding bats). This report provides a first exploratory look at some of the possibilities that acoustics could offer for surveying small terrestrial mammals in the UK.

A library of known species' recordings collected under controlled conditions was used to estimate likely detection distances under average conditions based on the frequency and intensity of calls. Acoustic recording was then compared with live-trapping by pairing a Longworth trap with two acoustic detectors, one placed at a low level (0.3–0.5 m) and another placed at a height that is typically used in bat surveys (2.5–3 m).

The findings were examined in relation to the potential role of structured and unstructured monitoring of small mammals.
