USDA Updates Plant Hardiness Zone Map, Minimum Winter Temperatures Rise
The 2012 USDA Plant Hardiness Zone Map continues to report some areas of the United States in warmer zones. This would affect the long-term viability of plant and tree species in specific zones, especially near the zone boundaries. Over time this would also impact the habitat, breeding, and migration areas of birds, insects, and other wildlife.
