BEST NATURAL HISTORY Secrets of Our Living Planet (BBC Two Wales, tonight, 7pm) [bar] If Chris Packham aspires to be the next generation's David Attenborough, he's going about it the right way. The man is a fountain of knowledge when it comes to natural history and he's also doing a good enough job of getting his face here there and everywhere on the Beeb. He's a stupendously intelligent man when it comes to the rarest of wildlife and the inner workings of the world's biggest rainforests; so get your thinking caps on because he's about to teach us a great deal more. This week, the presenter investigates the ecosystem of North America's temperate forests, exploring its ability to rebuild itself in the spring after the harsh winter - and amazingly it has a lot to do with the salmon. The changing of the seasons twice a year means that the entire ecosystem has to transform itself. Chris explains why the forest depends on the flying squirrel, and how the activities of a moth caterpillar in the spring are so important to the survival of the Canadian lynx in the winter. Tune in next week for the final part of this fascinating series.
