Mark-recapture live-trapping methods are both time-consuming and expensive, and the inference needed for management are often limited by both of these constraints. Many Pacific Northwest small mammal live-trapping studies have used a similar methodology, originally intended to develop precise estimates of flying squirrel (Glaucomys sabrinus, Glaucomys oregonensis) abundance. However, since the establishment of this methodology, improved estimators have resulted in abundance estimates that might be more precise than those needed for management inference. We intend on using multiyear live-trapping data obtained in three regions of Oregon to reassess the commonly deployed trapping methodology. Specifically, we are estimating the effects of site-specific reductions in trapping period on the standard error of abundance, detection probability, and apparent annual survival estimates.
