Rusty Keeler's Natural Playscapes, Creating Outdoor Play Environments for the Soul, published in 2008 by Exchange Press,is an explanation of and a workbook for creating children's outdoor play areas. These natural playscapes utilize “art, hills, pathways, trees, herbs, open areas, sand, water, music” so that “children will find places to run, climb, dig, pretend, and hide, with opportunities to bellow or be silent.” Believing the children need “a variety of rich, stimulating experiences and environments that support a wide range of play,” Rusty prefers the idea of a “landscape for play” or a “playscape.”
