16:00 – 17:00: Autumnwatch

Chris and Kate are in the Lake District to witness a British wood at its seasonal best - a colourful and spectacular sight. The trees are host to red squirrels, jays and tawny owls - all very busy at this time of year. Simon King is in Scotland to follow the fortunes of wild salmon - in autumn they face the daunting task of swimming many miles upriver to breed.
