Home gardens can add immensely to the biodiversity of cities and towns.
They provide cover, feeding and commuting routes for wildlife including hedgehogs, badgers, birds and butterflies. If you have a garden, increase its value by planting berry-bearing trees and flowering plants. Rowan, bird cherry and dandelion, among others, can serve as food and shelter to a wide range of invertebrates.
