I really appreciate their use of beaver damming mimicry. Ideally they'd expand the actual beaver habitat already in northern Texas, but this is at least a way to make habitat favourable for their eventual reintroduction. Here in the Rockies beaver ponds are the equivalent of a desert oasis, insulating ecosystems from drought and snow as much as wildfires. Their loss is one of the reasons we now have to deal with chronic wasting disease.
