Media Modifications For Native Plant Asemblages On Extensive Green Roofs, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

Great Plains and Midwestern regions might profit from selecting species representing nearby mid and short grass prairies, not the tall grass prairie. Such assemblages should exhibit needed characteristics desirable on low-input extensive green roofs to withstand stresses of: drought, heat, cold, nutrient deficiencies and wind before providing expected benefits. While published research, and its recommendations are inconclusive or negative regarding efficacy of native prairie species for extensive green roofs, establishment data gathered in this study demonstrates placing native plant assemblages for extensive green roofs into modified media significantly improves their establishment and growth.
