Why OGSP Recommends It
One Good Story Project recommends Route 3 Films because the St. Louis production company uses filmmaking to help people understand conservation work. In partnership with the National Great Rivers Research and Education Center, the team filmed The Call of the Swamp, a 15-minute documentary about the threatened bird-voiced treefrog and the southern Illinois wetlands it depends on.
By making the full film available free on YouTube, Route 3 Films helped bring the researchers’ work and the treefrog’s story to an audience beyond the scientific community.
