BBC Secrets of our Living Planet - The Magical Forest

Secrets of our Living Planet
In this series, naturalist Chris Packham reveals the natural world in a way that you've never seen it before. For him, what is really beautiful about nature is not the amazing animals and plants that we share the planet with but the hidden relationships between them. These relationships may sound bizarre but without them, no life would be possible. Discover previously unknown relationships, like why a tiger needs a crab; or why a gecko needs a giraffe. Each week Chris visits one of our planet's most vital and spectacular habitats and dissects it, to reveal the secrets of how our living planet works.
The Magical Forest
Chris travels to North America to witness the annual miracle of the temperate forest: the destruction of its ecosystem in winter, followed by it rebuilding itself in spring. Chris marvels at the exquisite timing that is necessary in two particularly wonderful stories - the story of how the Canada lynx depends for its prey on a caterpillar high up in the canopy, and the story of why the giant trees of the north-west are dependent on bears and salmon.
