If you have a large garden.

Put up bird and bat boxes. Plant a dense border to provide cover for small mammals. Consider leaving part of your lawn uncut for part of the summer. Long grass is beneficial to many species. Better still create a wildflower meadow and attract a host of butterflies. Create a pond or a water feature for frogs and newts. Plant a native species hedge to provide a home and food for birds and mammals. Remember to check if a species is native to Northern Ireland. Delay any major pruning of hedges and trees until late autumn outside the bird nesting season. Grow plants that flower in different seasons for a year round supply of food. Use organic methods to control pests. Source materials for your garden such as wood products responsibly. Look for the Forest Stewardship Council logo which ensures woodlands are managed sustainably.
