Abstract
The
steps necessary to conduct a pitfall trapping survey for small terrestrial
vertebrates are presented. Descriptions of the materials needed and the methods
to build trapping equipment from raw materials are discussed. Recommended data
collection techniques are given along with suggested data fields. Animal
specimen processing procedures, including toe- and scale-clipping, are
described for lizards, snakes, frogs, and salamanders. Methods are presented
for conducting vegetation surveys that can be used to classify the environment
associated with each pitfall trap array. Techniques for data storage and
presentation are given based on commonly use computer applications. As with any
study, much consideration should be given to the study design and methods
before beginning any data collection effort.
