Trees Forever works with volunteers in local communities to care for trees, native plants, and prairies. Together, they have organized more than 4,000 projects to plant more than 2.8 million trees and shrubs across Iowa and Illinois. The tree plantings, which take place in both rural and urban areas, help improve water and air quality, increase energy conservation, and help restore and beautify the natural environment. The organization’s urban farms, trail enhancement, and disaster-recovery efforts also connect locals to nature and serve as a resource for food and recreation. Another focus of Trees Forever is engaging the public in environmental stewardship. It produces educational materials for this purpose, such as the Spirit of the Trees documentary series, which examines Native Americans’ relationship with trees and forests.
