KBS080:Michigan GLBRC Extensive Sites

The Great Lakes Bioenergy Research Center’s (GLBRC) Extensive Sites are farm-scale fields located on working farms. Fields of corn, switchgrass, and restored prairie are represented at each of 10 locations in 13 counties in Michigan.

Tables

KBS080-001 Insect Counts via Sticky Traps

Insects counts via yellow sticky traps at Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study.

KBS080-002 Plant Biomass

Above-ground plant biomass of grassland, switchgrass and corn from Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study, divided into broad groups.
At each site, standing plant biomass was clipped to the ground and surface litter was collected from a measured area. Biomass was sorted into broad groups: corn ears, corn stalks, switchgrass, big bluestem, indiangrass, other grass, forbs and surface litter. Biomass was dried and weighed. Robel pole measurements were taken at each site to correlate to biomass.

KBS080-003 Plant Species Composition via Nested Circles Method

Plant species composition in the Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study via the nested circles method of 1, 10, and 100 m2 centered on the sampling station.

KBS080-004 Plant Density via Robel Pole Measurements - Raw Data

Robel pole measurements at Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study that correspond with plant biomass measurements to estimate plant density.

KBS080-005 Plant Species Composition via Transect Method

Plant species composition in the Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study using the transect method.

KBS080-006 Corn Stand Counts

Corn population estimates were done by counting the number of stalks and ears on a 1 meter quadrant at each station.

KBS080-007 GPS Coordinates of GLBRC Extensive Sites

Point location coordinates for Extensive sites of the GLBRC Biofuel Biodiversity Study collected with GPS (global positioning system).

KBS080-009 Soil Test Lab Analyses - Agronomic

Chemical analyses of soils taken from Michigan Extensive sites of the GLBRC Biofuel Biodiversity Study and analyzed by the Michigan State University Soils Laboratory.
