We compared the monitoring of small terrestrial mammals among forest stands by pitfalls and snap traps. The captures took place in the Czech Republic in the Moravskoslezske Beskydy Mts. (2007?2012) on 16 plots in adult beech and spruce stands between 910 and 1220 m a.s.l. In total, 14 species of small mammals were captured (12 in the snap traps and 10 in the pitfalls). Snap traps captured the broader species spectrum and they were more successful in capturing larger species of small terrestrial mammals consuming a higher proportion of plant food (mice, and in particular voles). The pitfalls were more effective in capturing smaller species with a predominance of animal food (shrews). To cover the widest species spectrum of small mammals, it is appropriate to use both types of traps. To observe the functional diversity of the community in terms of food composition, it is sufficient to use snap traps.
