Number 7 on my list of the top-10 green building priorities is to protect and restore the site. ... Build on the edge of a lot Whenever possible, we should build on the edges of lots, particularly with larger sites, and maintain the rest as permanently protected open space. The (more usual) practice of building in the center of a site means a longer driveway, greater ecological disturbance, and a larger proportion of the land that's in the "development zone." Restore the site Ecological restoration should be an important part of green building--especially in rural and suburban areas, but even--on a small scale--on urban lots. In many places invasive plant species have taken over the landscape, and their proliferation becomes a vicious cycle because they usually prefer disturbed sites. Removing these plants can allow native plants that support birds, butterflies, and other wildlife to return and help re-create healthy ecosystems. In some cases, nature will need a hand bringing back native plants; look for sources of locally sourced native plants, or collect seeds of native plants in your area, and plant them on the site you are restoring. Try to achieve diversity in your plantings. Native landscaping and a bioretention basin at the Chesapeake Bay Foundation headquarters. Photo: Alex Wilson. Click on image to enlarge. Reduce lawn area A good place to start with ecological restoration is to reduce the amount of lawn. Most turfgrass is Kentucky bluegrass--which isn't from Kentucky at all; it's native to Europe. Maintaining vibrant green lawns in many parts of the country requires extensive use of herbicides, chemical fertilizers, and irrigation water. Non-turf landscaping using native plants avoids the need for these inputs. Provide for wildlife As our larger landscape has become more and more broken up with roadways and development, wildlife has increasingly been forced out. On larger sites, learn about wildlife corridors that may exist (or have existed) and try to maintain or re-create them. Look for opportunities to connect patches of protected wild areas so that wildlife can pass back-and-forth freely. Plant trees and shrubs that provide food for wildlife. The National Wildlife Federation offers useful information for enhancing backyard wildlife habitat. Help homeowners enjoy natural areas and wildlife In our design of homes and the landscapes around homes, look for ways that will help the people living there (or visiting) appreciate nature and want to protect it. Provide outdoor living spaces with patios, decks, and screen porches, and design indoor spaces with windows that look out on nature. Such efforts may help build appreciation for--and incentive to protect--natural areas. The top-10 list of priorities so far: #7. Protect and restore the site #8. Use green materials #9.
