Several legal acts mandate that management agencies regularly assess biological populations. For species with distinct markings, these assessments can be conducted noninvasively via capture-recapture and photographic identification (photo-ID), which involves processing considerable quantities of photographic data. To ease this burden, agencies increasingly rely on automated identification (ID) algorithms.

- Understanding the health status of long-lived species is crucial for their management, but traditional monitoring methods are slow, often taking decades to reveal changes in populations.
- A new approach using Unoccupied Aerial Systems (UAS) photogrammetry was tested to assess the age structure of bottlenose dolphins, offering a potential early warning system for population decline.
- Results showed that UAS estimates can accurately determine the total body length of dolphins and classify age groups effectively, with a high percentage of individuals being correctly allocated to their age classes within two years.
