Acoustic Localization and Density Estimation

Automating acoustic tools to estimate species abundance for efficient, large-scale conservation monitoring.

Abundance or density estimation is essential for understanding species population dynamics, and thereby key to identifying threats, administering protective measures, and evaluating their efficacy. Traditionally, abundance estimation has been performed through expert observation in the field, which is highly time- and effort- intensive. In recent years, acoustics has shown promise for providing counts of vocalizing animals by localizing individuals within the environment. Paired with established statistical methodologies, such as distance sampling or spatial capture-recapture, the use of an acoustic array offers an opportunity to automate and expand population monitoring. Altogether, our goal is to develop and implement streamlined tools for acoustic localization, and perform large-scale abundance estimation for conservation priorities in both marine and terrestrial environments.
