"With the accelerating pace of development and subsequent habitat disruption, the pressures on wildlife populations are greater than they have ever been in our nation's history. As Doug Tallamy has confirmed through extensive research, there is an unbreakable link between native plant species and native wildlife. When native plant species disappear, or are replaced by alien exotics, the insects disappear, thus impoverishing the food source for birds and other animals. Fortunately, there is still time to reverse this alarming trend, and gardeners have the power to make a significant contribution toward sustaining biodiversity. By favoring native plants, gardeners can provide a welcoming environment for wildlife of all kinds" -- publisher website (March 2008).
