The 2013 report highlights the enormous contributions private landowners make to bird and habitat conservation, and opportunities for increased contributions. Roughly 60% of land area in the United States (1.43 billion acres) is privately owned by millions of individuals, families, organizations, and corporations, including 2 million ranchers and farmers and about 10 million woodland owners. More than 100 species have 50% or more of their U.S. breeding distribution on private lands.his State of the Birds report reveals troubling declines of bird populations during the past 40 years—a warning signal of the failing health of our ecosystems. At the same time, we see heartening evidence that strategic land management and conservation action can reverse declines of birds. This report calls attention to the collective efforts needed to protect nature’s resources for the benefit of people and wildlife.
