Monitoring Vocalizing Species by Engaging Community Volunteers Using Cell Phones

Abstract

ABSTRACTBiodiversity monitoring is important for species and habitat management, although it can be costly in terms of personnel time and expertise. Citizen Science projects that engage community participants to collect species distribution data can provide high volumes of data at little cost, but data are often associated with unknown observer error. Projects that remove decision‐making (e.g., species identification) allow for higher participation because expertise requirements are eliminated. We piloted a project using Citizen Science principles to solve logistical challenges for a synoptic amphibian survey across an island array in the United States Virgin Islands by inviting the community to collect recordings of frogs using cell phones. We received >270 recordings and location data from community participants during a 2‐week survey window; these were processed manually, using bioacoustics analysis software for species identification and location. Species detections were comparable to previous methods of survey although new distribution records were substantially increased. Utilizing Citizen Scientists to conduct recorded surveys of amphibians using cell phones offers a low‐cost method for expanding survey effort for predictably‐vocalizing species. © 2020 The Wildlife Society.
