Importance of native trees
Restoring native plant habitat is vital to preserving biodiversity. By creating a native plant forest/ garden, each patch of habitat becomes part of a collective effort to nurture and sustain the living landscape for birds and other animals.
Native plants are those that occur naturally in a region in which they evolved. They are the ecological basis upon which life depends, including birds and people. Without them and the insects that co-evolved with them, local birds cannot survive. For example, research by the entomologist Doug Tallamy has shown that native oak trees support over 500 species of caterpillars whereas ginkgos, a commonly planted landscape tree from Asia, host only 5 species of caterpillars. When it takes over 6,000 caterpillars to raise one brood of chickadees, that is a significant difference.
Unfortunately, most of the landscaping plants available in nurseries are alien species from other countries. These exotic plants not only sever the food web, but many have become invasive pests, out-competing native species and degrading habitat in remaining natural areas.
Landscaping choices have meaningful effects on the populations of birds and the insects they need to survive. The bottom line is this—homeowners, landscapers, and local policy makers can benefit birds and other wildlife by simply selecting native plants when making their landscaping decisions.
To do your part, you can contact your city’s forest department to discover native plants in your area and which types of birds they’ll attract.
