I presented my latest work on drone‑based surveys to estimate moose populations. Using simulations, we were able to: - Compared various drone platforms - Found that fixed‑wing drones equipped with a gimbal‑mounted camera provide a viable, safe alternative to conventional methods. #TWS2025 #drone

Preliminary results are in: Fixed-wing drones show strong potential for moose surveys. Monitoring moose populations has been traditionally done by helicopter. Our partners at UBC are exploring if drones are a better alternative. 🔗Learn more: friresearch.ca/publications... @irssubc.bsky.social

If you don't think the IRSS flies #drones in the winter, you've never done field work with Leanna (@la-stack.bsky.social) & Kirk! ❄️ Leanna was out collecting leaf-off #lidar & #ThermalImagery of winder conditions for trout-bearing steams in Alberta with @friresearch.bsky.social!

@friresearch.bsky.social recaps postdoc @l-hambrecht.bsky.social's recent field work in Hinton, Alberta to test the use of thermal #drones over horses in the area 🐴 The horses were used as proxies for moose detection under various canopy cover to survey #moose populations Stay tuned for findings!

High tech, meet the horses! Folks from Integrated RS Studio came to test their tech for identifying ungulates under canopy cover. We’re short on trained moose that will stand around where we want them, so we used our biologist’s horses as test subjects! 📷 Arya Horon, Caroline Lesage

Unfortunately this is nothing new. I've worked on online IWT for 15yrs, others for 20yrs. I fear many 'initiatives' are treated as green washing by social media companies. ‘It shouldn’t be that easy’: inside the illegal wildlife trade booming on social media www.theguardian.com/environment/...

Social media sites have become crucial tools for the sale of endangered species and platforms should do more to combat it, say experts
