How can people help

Many of our common, less showy plants are often overlooked; but they are still beneficial to wildlife, providing food and shelter for insects and, in turn, supporting the animals that feed on them. Try leaving wilder areas in your garden, such as patches of flowers on old walls and nettles near the compost heap, and see who comes to visit... To find out more about wildlife-friendly gardening, visit our Wild About Gardens website: a joint initiative with the RHS, there's plenty of facts and tips to get you started.
