The United States Department of Agriculture (USDA) Forest Service has set up a Smart Forests network of long-term experimental forests and research sites across the US. The network is using a range of sensors to provide real-time data on air temperature, precipitation, relative humidity, wind speed, solar radiation, soil temperature and moisture, stream flow, and tree phenology , for monitoring and managing urban and rural forest environments. See a map of the participating experimental forest sites here. Learn more about the Smart Forests network in our radio episode with Lindsey Rustad.

The Hubbard Brook Experimental Forest is a 7,800-acre hardwood forest in the White Mountain National Forest in New Hampshire. Established as a research site by the USDA Forest Service in 1955, it is renowned for the long-term Hubbard Brook Ecosystem Study ongoing since 1963. A sensor network collects data on air temperature, solar radiation, soil temperature, precipitation, humidity, wind speed, and other phenomena at weather stations distributed across the site, and web cams monitor tree canopy phenology . Real-time data from the forest can be viewed here.
