Visual Surveys Rapid Response Saipan 2016
September 25, 2020
Nocturnal visual encounter survey data conducted by 29 searchers over 17 transects obtained during a Brown Treesnake rapid response deployment to island of Saipan in 2016. Surveys took place in the vicinity of the Saipan airport and Dandan village (ca. 15.127°N, 145.735°E) from 06 January to 13 March 2016, 6-7 nights/week but with a break in surveying from 26 January through 21 February. During Brown Treesnake searches over 386.8 kilometers, we collected data on selected vertebrate taxa (lizards and small mammals, both potential snake prey) recorded from survey transects with similar vegetation structure (secondary forest dominated by the introduced leguminous tree Leucaena leucocephala; emergent trees were partially denuded from typhoon Soudelor which had passed over Saipan on 02 August 2015).

Do observer fatigue and taxon-bias compromise visual encounter surveys for small vertebrates? Do observer fatigue and taxon-bias compromise visual encounter surveys for small vertebrates?
Context. Visual encounter surveying is a standard animal inventory method, modifications of which (e.g. distance sampling and repeated count surveys) are used for modelling population density. However, a variety of factors may bias visual survey counts.Aims. The aim of the present study was to evaluate three observer-related biases: (1) whether fatigue compromises detection rate as a...
