PROTOCOL FOR SAMPLING MEDIUM- AND LARGE-SIZED TERRESTRIAL AND ARBOREAL MAMMALS USING CAMERA TRAPS IN RAPELD PLOTS

Abstract

Using camera traps for sampling mammals has become increasingly common in recent years, enabling the integration of data from different research groups. However, for even more efficient integration, it is essential to standardize sampling methods for inventories and monitoring of medium and large mammals using camera traps (CTs). Consistent protocols are fundamental to ensure data comparability across different spatial and temporal scales, improving the understanding of population dynamics and ecosystem health, and optimizing conservation efforts. In this regard, our work proposes a standardized minimum protocol with guidelines for sampling medium and large mammals using CTs in RAPELD plots. These guidelines address pre- and post-fieldwork procedures, and schedules to account for weather conditions. The protocol also covers technical aspects of installation, such as camera height and orientation, to ensure effective image capture. The use of CTs allows continuous monitoring, and a minimum operational period of 30 days is suggested for efficient recordings, with periodic inspection for maintenance and battery replacement. Data screening and spreadsheet organization are discussed with suggestions to optimize the organization and analysis of captured information. By implementing this standardized protocol, we hope to facilitate data integration in future studies, promoting a unified approach for monitoring and conserving mammals in Neotropical ecosystems. This methodology can be adapted for various environmental contexts and has the potential to significantly contribute to biodiversity conservation strategies and natural resource management.
