Finally some good news. I had no idea the Ohio Department of Wildlife had such an outstanding role in the recovery in the Great Lakes region. River otters are really interesting creatures.

Humboldt State supports an active citizen science project to observe and document river otter populations in the ~watershed of Humboldt Bay in Northern California. It's a cool model for engaging with the community to help protecting its natural resources. I could easily imagine similar resources in other regions. * https://hsu.reclaim.hosting/NorthCoastOtters/
