Pantanal Escapes

This is a short preview from episode 2 of BBC Secrets of our Living Planet (Secrets of the Savannah) showing grassland regions in South America and elsewhere. It focuses on the critical role that nitrogen plays for natural grasslands - and how plants and wildlife have adapted to survive in nitrogen-deficient environments.

The full episode, and the series, is available from iTunes although mightn't be available in all regions.
