This guide complements the California Tree Palette for Schoolyard Forests, published by Green Schoolyards America, and aims to assist school districts, landscape architects, and school communities in choosing suitable trees for their region and schoolyard context that will thrive as temperatures rise over time. Design considerations outlined include species diversity, planning for a healthy ecological system, support for learning and play, and planning for manageable maintenance. Tree attributes outlined include species suitable for changing temperature conditions, ecological benefits, and heath, among other factors.
