In 2013, GLBRC Marginal Land experimental sites were established in Wisconsin and Michigan to evaluate the potential for using lower productivity fields for low input bioenergy feedstocks.  There are six sites; Wisconsin and Michigan each have a site in the south, central and northern parts of the state (see map below with locations on state maps). All six cellulosic biomass crops, treatments G5-G10, and a no change control (G11) are replicated in 4 blocks. The plots are approximately 64 feet x 40 feet except for G8 (poplar) which is 64 feet x 64 feet.  The treatments include G5-switchgrass (Panicum virgatum variety Cave-in-rock), G6- giant miscanthus (Miscanthus x giganteus), G7- a 5-species native grass mix, G8- hybrid poplar trees (“NM-6”, Populus nigra x populous maximowiczii), G9- an early successional community, and G10- native prairie.
