WebAbove-ground standing crop (ASC) dynamics were followed over a two-year period in three coastal grassland communities. The mass of biomass, necromass and litter components was determined monthly from hand-clipped samples and compared under three management treatments - grazing, burning and protection from defoliation. WebThe litter standing crop carbon storage was 10.93 Tg C, 7.40 Tg C, and 3.53 Tg C in desert shrublands and alpine shrublands, respectively. Litter standing crop carbon decreased with longitude, and was stable with increasing latitude. Most (80%) of the litter standing crop was stored in branches, with only 20% stored in foliage in the shrublands ...
