Plant native: save the birds and the bugs By Lyn Dean

eclaiming biodiversity lost to development and growth is something in which we can all participate—whether it’s within your backyard or your company’s next landscape design. Scientists and horticulture experts from around the world are reaching similar conclusions about the value of native plants in ecosystems. It’s not simply that native plants are naturally adapted to the soil, climate and other environmental conditions; they are key players in local ecosystems, which are made up of myriad fauna and flora species, also adapted to the conditions. In fact, all evolved together creat-

ing a complex and mutually beneficial system. Research by entomologist Doug Tallamy, University of Delaware, indicates caterpillars and other insects are more abundant on native plants compared to non-native species in urban areas. As a consequence, more insect-eating birds were observed on native plants, and more nesting activity of birds occurred in areas with more native plants—the plants that provide more bugs as food for the young. A 2016 study by Audubon scientists reported one third of North American bird species have declined in the past 50 years and are at risk for extinction. With continuing devel-
opment, saving natural biodiversity is critical. Colorado State University Extension experts note that native plants require less water, fertilizer and maintenance—though it is important that they be placed correctly. They also warn against taking a native plant from the wild, because it reduces biodiversity and disturbs the area, potentially leaving it vulnerable to invasive plants. Once established, native plants may attract a variety of wildlife including birds, bees, butterflies and other native pollinators as well as mammals. Planting natives, even on small scale, helps maintain biodiversity. |CG
