Countryfile: Season 30, Episode 12

30 - 12: Shropshire

As the birthplace of the industrial revolution, this is a landscape rich in coal and iron. But the legacy of one of the ancient coal shafts is a river that is colourful for all the wrong reasons - it runs bright orange with iron-rich ochre from the rocks below. Matt Baker immerses himself in Shropshire Wildlife Trust's Love Your Rivers project. It's a huge conservation operation, involving 12 organisations and an army of volunteers inspired to give their landscape some TLC. Ellie Harrison accompanies sniffer-dog Lunar in a search for pine martens. She also meets James Sherwin - a man who set himself a 12-month mission - to cook for a whole year only using ingredients farmed and grown in Shropshire. Steve Brown spends the day with Becky Haywood, an artist who combines her love of nature with molten glass. Adam Henson has a round-up of life on the farm as spring sets in. As the numbers of one the UK's favourite mammals plummets, Tom Heap asks where have all our hedgehogs gone?
