Techniques for trapping and tracking stoats (Mustela erminea); a review, and a new system

Abstract

Systematic direct observations of the small, fast-moving, and wide-ranging stoat are rarely practicable. The simplest indirect methods of observation are kill-trapping, live-trapping, and footprint recording. The data obtainable and the advantages and disadvantages of these methods are reviewed. Two new kinds of traps and a footprint recording system are described; they are especially suitable for use in rugged field conditions far from base facilities. When operated together in suitable habitat, these techniques can provide useful information on the population structure, feeding habits, and natural movements of stoats. Together or singly they also have potential as management tools, especially in identification of nest predators and in faunal surveys of islands. © 1977 Taylor & Francis Group, LLC.
