“The population is relatively small here in Western Australia, so we really want to get a feel for whether the population is increasing, staying stable or decreasing,” she said.“The population is relatively small here in Western Australia, so we really want to get a feel for whether the population is increasing, staying stable or decreasing,” she said.
“If we are able to to identify a method for reliably identifying individuals over time, then we can actually obtain accurate estimates of population size as well as look at their residency patterns and how they’re using habitats and areas, and how far they actually move between islands.”“If we are able to to identify a method for reliably identifying individuals over time, then we can actually obtain accurate estimates of population size as well as look at their residency patterns and how they’re using habitats and areas, and how far they actually move between islands.”
Previously, researchers have used crowdsourced photos combined with computer algorithms developed by NASA to identify polar bears and whale sharks based on spot patterns. These visual methods are easier than using microchips or other tagging techniques.Previously, researchers have used crowdsourced photos combined with computer algorithms developed by NASA to identify polar bears and whale sharks based on spot patterns.

for a couple of reasons”. Readers can contribute photos of sea lions from Western Australia and South Australia at the Whisker Patrol website. If you are photographing a sea lion, please be aware that they are a large wild animal that may respond if threatened. Always remain at least 10 metres from sea lions and observe the other guidelines here.
