Green Roof

Look up as you approach the Pavilion to find a living, green roof!  The prairie extends to our roof, to blend into the beautiful Arboretum vistas and as an example of a low-impact structure.

Green roofs are alive with plants that supply similar ecosystem services as ground-level plant communities.  Foliage and roots hold and filter stormwater that would otherwise runoff to other areas. Rooftop plants absorb more sunlight and heat while turning out habitat, food and water for wildlife, such as birds or insects.

However, green roofs require a thoughtful plan to accommodate certain plant communities without excessive maintenance.  You can find recommended resources below.
