Going through the certification process for any of the various backyard habitat programs will help guide the design of your yard to make it more wildlife friendly. Just by planting appropriate plants provides shelter and sustenance for entire ecosystems. Displaying signs that designate your property as pollinator friendly or bird friendly is visual encouragement for others to do the same.
