Oak trees help create healthier communities. Trees clean our air by removing air pollution, purify our drinking water and keep us cooler in the summer. Our oak trees can help reduce water pollution, reduce asthma, and improve our overall health. Oaks support more than 500 species of plants and animals, including butterflies, moths, bees, and birds. Some are rare and endangered species. The 250 species of migratory birds that pass through the Chicago region each year prefer oaks. Virginia bluebells, trout lilies, and trillium abound in healthy oak woodlands. Oaks’ shade lowers water temperatures in streams to improve conditions for fish.
