Matt Baker and Julia Bradbury head to the vast chalk grasslands of Salisbury Plain. These great bare uplands were once at the heart of a prehistoric civilisation so powerful it drew people from all over Europe. Those days are long gone but there are still remains that lie hidden. Julia finds out how to keep archaeological remains safe when there is farming and wildlife to contend with, and she discovers the lengths people go to protect the country's heritage.

Matt is helping spruce up a more recent addition to the landscape - the Cherhill horse. Also on Salisbury Plain, Katie Knapman's flying high, getting a forecaster's view of how to map the weather.

Elsewhere, John Craven investigates whether British farmers will make money from the global beef boom, and Adam Henson goes in search of some rare breed White Park cattle to add to his herd. Show less
