In searching for podcast examples that are relevant for my work with the Refuge, I came across a really wonderful resource for independent filmmakers, Terra: the nature of our world. Appears to be a site sponsored by Montana State University, and I think it mostly features advanced student work.
I just watched this 30 minute film about wildlife connectivity and ground truthing a corridor between Yellowstone National Park and the Frank Church Wilderness. Worth watching! And, I want to do the same thing for our research projects. The Kodiak bushwacking would put these guys to shame 🙂
