Autumnwatch is back, but this time with a difference - for the first time ever the team are coming live from America. Every year six billion trees across New England turn into a riot of yellows, reds and golds, and Chris Packham, Michaela Strachan and Gillian Burke have travelled to New Hampshire to beam live pictures of this phenomenon back to the UK.

Live from their base in the heart of New Hampshire, Chris Packham, Michaela Strachan and Gillian Burke bring us the latest happenings from deep in the American woods. We learn about the science of how this spectacular leaf change comes about, and meet some of the smaller residents who change colour along with the leaves.
