A ten year study of a one kilometre stretch of the River Itchen at Martyr Worthy, Hampshire – one of the finest wild brown trout rivers in the world. This highly illustrated account of the wildlife (birds, plants, insects, animals, fish, reptiles, snails) and riverkeeping and river engineering activities gives an insight into life on the river through the seasons and across the years. Underwater and night vision images reveal hidden life and features. Historical detail, combined with contemporary accounts and aerial mapping, bring the past back into focus. Conservation is discussed. ‘Art in Nature’ is featured to engage with children, artists, poets and story-tellers. Fieldcraft, equipment and techniques are also described.
