Although the economic, environmental, and aesthetic benefits of green roofs have been recognized for decades, research quantifying these benefits has been limited—particularly in the U.S. Green roof usage and research is most prevalent in Germany, but can also be seen in several other European countries and Canada. If green roof installations are to be successful in Michigan and the rest of the U.S., then a better understanding of what specific taxa will survive and thrive under harsh rooftop conditions in this geographic area is required. Nine simulated rooftop platforms containing three commercially available drainage systems were installed at Michigan State University. Eighteen Michigan native plants planted as plugs and nine Sedum spp. planted as either seed or plugs were evaluated over three years for growth, survival during both establishment and overwintering, and visual appearance. All Sedum spp. tested were found to be suitable for use on Midwestern green roofs. Of the eighteen native plant taxa tested, Allium cernuum L., Coreopsis lanceolata L., Opuntia humifosa Raf., and Tradescantia ohiensis L. are suitable for use on unirrigated extensive green roofs in Michigan. If irrigation is available, then other native species are potential selections.

This ISSUE is almost totally comprised of the first half of a two part publication series that relates Africanists to the Africa policy of the U.S. government. As a whole, the two parts—in this and the next ISSUE —review the relationship of the opinions and the activities of the Africanist community outside the U.S. government (mainly academics) to the thrust and substance of policy and the process of policy-making inside the U.S. government. The two major articles in the present ISSUE—on Africanists and U.S. foreign and national security policy by Larry Bowman of the University of Connecticut, and on Africanists and U.S. economic assistance policy by Michael Bratton of Michigan State University—represent the first part.
