You step out of the back door into the garden. There may be a few birds flitting around, perhaps butterflies or bumblebees on the wing, but often the garden can seem very still. However, if you look beyond the superficial inactivity there is an ecological web of wildlife to explore, to understand and then to encourage more biodiversity. The Science of Garden Biodiversity: The Living Garden shows how data and science can help to dispel myths, such as that wildlife gardens are great for wildlife (and other gardens aren't), that a garden fit for wildlife must be 'wild' and that you must grow native plants. It also provides an understanding of how diverse life can be in gardens and how gardens work. And along the way there are scientific 'signposts' to better wildlife gardening. Julian Doberski explains the role of 'small things' - microorganisms and invertebrates - that are fundamental to the ecological functioning of gardens. Learning more about the ecology of a garden helps us understand what makes a garden a refuge for wildlife and how following the science may lead to a more thoughtful and constructive approach to gardening, garden design and garden planting.
