In the absence of a more precise standard against which to calibrate, at least nine trap data interpretation methods have been developed, each yielding different values. Home ranges generated from these methods were compared to those calculated using much more accurate radio telemetry to determine the former's relative precisions. The standard circle and Koeppl's 70% ellipse generated home ranges closest to those determined with radiotelemetry.
