#9 Biomass alder plantation

These speckled alders were planted in 1993 as a biomass research project. Most common in the Great Lakes–St. Lawrence region, they grow rapidly enough to create biomass for energy production. This thicket-forming shrub can pull nitrogen out of the air and deposit it in the soil for other plants to use—a process known as nitrogen fixing.
