How Wolves Change Rivers

A short video on how the re-introduction of wolves to Yellowstone in the 1990s led to a smaller population of deer. This led, in turn, to the regeneration of plant life, which brought in more birds, beavers, otters, rabbits, mice, bears (who had more berries to eat), fish, and, eventually changed the course of rivers (because with more vegetation there wasn’t so much run off).

Or, the importance of preserving, tracking, sharing, comparing, and analyzing data so you can correlate one thing (i.e., the re-introduction of a species) with another (i.e., increased vegetation and the subsequent increases in other animal populations, as well as changes to the geophysical environment).

Please let me know what you think....
