Seasonal Forests

Seasonal forests are special. Their ecosystems have to cope with drastic change twice a year, in Spring and Autumn. Not only do the individual inhabitants have to deal with that change, but the entire ecosystem has to transform itself at exactly the same time – and it can only do this if all the animals work in perfect synchronicity.
This entire episode is spent in the vast seasonal forests of North America, over the course of a year. Episode hi-lights include footage of flying squirrels leaping from tree to tree in the fall, how a lynx survives the winter, the crucial effect that caterpillars have on the forest canopy, and the importance to the forest of a bear’s fishing exploits.
