| dc.description.abstract | Twenty-one marine mammal species are designated under the Species at Risk Act (SARA) in Canada. When species are designated under SARA, management plans, recovery strategies, and action plans are outlined to prevent wildlife species from being extirpated or becoming extinct. In these plans, monitoring and outreach are often key recovery objectives for the species. Opportunistic sightings (OS) can help support the monitoring and outreach of species at-risk and can provide an important source of information on the presence of a species when systematic surveys are impractical or costly. To better understand the use and value of OS for cetacean conservation and management, marine mammal experts in Canada were interviewed (n= 15). A thematic analysis was used to examine the qualitative data of the interviews. Results suggested that OS are being used in a variety of different ways, from filling in data gaps, creating species distribution maps, informing management measures and being used as education and outreach tools. Experienced observers and reliability of a sighting were reported as key to being able to use the data. One main limitation of OS is the potential for poor data quality. Recommendations on how to improve OS for cetacean conservation and management include improving the quality of OS data by adding pictures or videos of cetaceans when reporting and using mobile applications to help record data, create a centralized database where open-source data is shared across the country, and improve education and outreach programs to increase cetacean identification training sessions for stakeholders on the water.
