A tremendous number of resources are available to support the development of outdoor classrooms and outdoor curriculum. We have compiled a brief listing of some books and other materials you may want to consult. Although some of the books are out of print, they are included because you may be able to obtain them through specialty mail order companies, or from your local library. Please note that in compiling this list, we have relied on information contributed by many individuals. Therefore, information such as the age of the intended audience may be highly variable. Please rely on your own judgement in determining whether any publication is appropriate for use in your classroom.
