Sally Coulthard explores the miraculous world of the earthworm, the modest little creature without whom life as we know it would not be possible.

The author of The Hedgehog Handbook reveals the miraculous world of the earthworm. Without these little engineers of the earth, the world's soils would be barren, and our gardens and fields wouldn't be able to grow the food we need to survive. Worms recycle decaying plants, putting nutrients back into the soil; they provide a food source for wildlife; and their constant burrowing helps heavy rain soak away.

Sally Coulthard's fascinating guide offers a wealth of information and practical advice about the world's most industrious but little understood creature.
