Figure 2. Three Dimensional LAI Profiles. LAI (density) profiles calculated from field collected PAR profiles based on new model developments. The S. alterniflora marsh is highly lodged in 2010 as indicated by the LAD of 1.04 (dominantly horizontal orientation). The marsh underwent a severe dieback in 2011exhibited as decreased LAI, increased vertical orientation (LAD, 0.59), decreased live-total ratio, and loss of total biomass (vertical summed LAI). High live-dead ratio, increased fuel load, and largely vertical orientation (LAD, 0.40) accompanied regrowth.
