The LPI procedure consists of lowering a sampling pin or rod through the vegetation at regular intervals along a set of transects in each plot and recording the first plant species intercepted vertically in its path or the type of ground cover if not intercepted by plants. Percent cover for each plant species is calculated as the number of times that species is recorded (a “hit”) divided by the total number of sampling points along the transect. Height of the intercepted plant is also measured to provide information on community structure.
Sampling frequency: Once annually at or near maturity of the dominant plant species, typically August-September.
Sampling details:
Marginal Land Experiment: beginning 2017; Treatments G5-11; 4 transects/plot: 2 in the fertilized portion and 2 in the unfertilized. Method 2
Biofuel Cropping System Experiment: beginning 2018, Treatments G2-10; 3 NS transects per plot, main only. Each transect predetermined distance and direction from the station flags and numbered 1-3 based on the station number. Stop about every 1m to identify and measure first intercepted plant. Method 2
GLBRC Scale-up Experiment: beginning 2018; 4 NS transects stretching the full length of fields L2, L3, M2, M3, M4. Stop about every 5m to identify and measure first intercepted plant.
