There's a growing appreciation for the importance of urban forests - cite a recent June 29/18 CBC discussion. The Carp River Wetland Environmental Area has a number of trees ??, shrubs ?? and plant space some of which could be arranged in a design appropriate for meeting spaces. Ideally each school within walking distance of the Environmental Area would have ready access to their own space which would be used for studies, stewarding initiatives and providing environmental information.
Being outdoors with nature in a variety of student led Interpretive Green Spaces will likely be a more meaningful experience than being under cover of a constructed facility.
