Postdoc at #UBC, researching the use of #drones to estimate #wildlife populations sizes.
Hiroto Goto presented his exciting work on drone‑based moose population surveys at #tws2025. Can’t wait to see his research develop further! 🌲🦌 #WildlifeScience #DroneTech

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.

I'm excited to present my work on surveying wildlife with drones and connect with the TWS community #TWS2025
Join me, Monday 9:15 in Salon 8
Will we be seeing you at The Wildlife Society's 2025 conference in Edmonton this week? 🦌 #TWS2025

Leonard (@l-hambrecht.bsky.social) and Hiroto will be sharing their research on how #drones, #ThermalImaging, and #DeepLearning are advancing conservation research.

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.

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!

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.
