It also reduces non-native introduced species which can further decrease biodiversity and vital habitats that are essential to the Eco-system. The use of inorganic materials, such as herbicides, pesticides and fungicides, can harm the environment. With the use of organic lawn management and other ecological techniques, the impact on lawns can be greatly reduced. Some of these methods include higher mowing techniques; the use of sedges, local grasses and low herbs; exclusive compost and organic fertilizer use; low volume irrigation; a pest management program that has been integrated; grass clippings from grass cycling ; and the use of a variety of shrubs, trees, perennials and other plants surrounding the lawn.
