Ah. Grigg et Dr. Mulligan, Biometric relationships for estimating standing biomass, litterfall and litter accumulation of Acacia salicina on mined land in central Queensland, AUST J BOT, 47(6), 1999, pp. 807-816
Basal stem diameter was found to be a good predictor of above-ground biomas
s, canopy litterfall and mass of the accumulated litter layer for Acacia sa
licina Lindl., a tree that establishes successfully on mined land in centra
l Queensland. The relationship between stem diameter and both biomass and l
itterfall was best described by an exponential model, and was related to ex
ponential expansion of the canopy as tree diameter increased. In contrast,
a simple linear model was used to describe the relationship between stem di
ameter and accumulated litter, partly reflecting a constant rate of litterf
all per unit area of canopy over the range of tree sizes. The models were d
eveloped as a means of estimating biomass and nutrient capital and cycling
in reconstructed ecosystems following open-cut coal mining.
