Recognizing the critical role of small mammals in forest biodiversity, the study aims to develop efficient monitoring techniques crucial for conservation and management efforts. Addressing two primary objectives, the research compares the effectiveness of three distinct camera-trap survey techniques (ground, tree, and tube) with traditional live trapping methods, and explores the species composition across old- and second-growth forest stands.Results reveal that camera-trap methods outperform live-trap techniques, demonstrating higher small mammal diversity and significantly increased capture rates. Moreover, the study finds that camera-traps are more cost-effective, reducing labor and ethical costs compared to live-trapping. Ten small mammal species were detected, with higher activity recorded in old-growth stands. The tube camera method proved most effective in capturing species richness. This research contributes to a deeper understanding of small mammal ecology in redwood forest ecosystems, supporting informed decision-making for conservation and management strategies in fragmented landscapes. The findings underscore the efficacy and cost-effectiveness of camera-trap techniques, emphasizing their importance in monitoring small mammal populations for effective conservation planning.
