Canopy Species and Height — GLBRC Scale-up Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
The composition and cover of canopy-forming plants is measured in switchgrass, restored prairie, and reference fields at Lux Arbor Reserve and Marshall Farm using the line-point intercept method. The first plant species intercepted vertically and its height is recorded every 5 meters along four NS transects stretching the full length of each field.
This datatable is part of the GLBRC Scale-up Experiment Cropping Systems dataset.
This dataset contains data on plant communities in fields at Lux Arbor Reserve (L1-L3) and Marshall Farm (M1-M4) planted to corn (L1, M1), switchgrass (L2, M3), and restored prairie (L3, M2) in 2010 after a 2009 no-till soybean crop in all fields to convert tilled corn-soybean-wheat rotations (AGR) at Lux Arbor and fields in the Conservation Reserve Program (CRP) at Marshall Farm to no-till bioenergy crops. One field at Marshall Farm (M4) remains as CRP brome grass to serve as a reference. Each field has 10 sampling stations (S1-S10) around which most sampling occurs.
