The United States Department of Agriculture is responding to climate change by updating the Plant Hardiness Zone Map for the first time in 20 years. The map shows where various types of plant species can thrive, and as warmer annual temperatures move northward, the more than 80 million U.S. gardeners and farmers will be looking to the map to see what new plants may be able to grow in their area. The Plant Hardiness Zone Map is typically used for domesticated plants, but this graphic display also sheds light on how native plant species are shifting due to climate change. The updated map is due out later this year.
