Jim Greenman, author of Caring Spaces, Learning Places: Children’s Environments that Work (2005), offers additional suggestions to enhance the outdoor learning environment:

• Organize your space
• Increase the use of water—add tubs, sprinklers, gutters, and sprayers.
• Freshen up your space by adding shrubs, boulders, logs, and container plants.
• Bring attention to outdoor art—add easels, chalk, paintbrushes, and buckets of water.
• Develop a pathway—use pavers or bridges.
• Add an ornamental fence to help define a space.
• Create a space for drama, such as a platform or playhouse.
• Add bird feeders, birdbaths, or butterfly gardens.
• Add short benches, step stools, or saw horses.
• Add picnic tables and benches.
• Create a safe throwing area.
• Create a safe jumping platform and vary the heights from one inch to incrementally higher.
• Create a gathering area for small groups or families.
• Create places to balance, such as beams, logs, and stumps.
