Some experts say that at least 80 percent of the plants growing in our yards are exotics that have little or no food value for native wildlife. This has contributed to the decline in native plant and animal populations in suburban settings.
Just one example of this is studies have shown there is 35 times more caterpillar biomass in native woody vegetation than is found in exotic woody plants. This is important because caterpillars are a key source of food for many wild animals. For example, 96 percent of terrestrial birds eat caterpillars.
With this in mind, if you are interested in increasing the variety and numbers of native animals in your yard, expand the number and diversity of native woody plants that grow on your property.
