Environmental effects on biomass productivity of wild populations of Yucca schidigera in Baja California, Mexico


, : Environmental effects on biomass productivity of wild populations of Yucca schidigera in Baja California, Mexico. Southwestern Naturalist 47(4): 576-584, December

Aboveground biomass of 4 populations of Yucca schidigera in Baja California, Mexico, and its relationship with environmental conditions, associated vegetation, density, and colony structure (size and diameter of stem) are described. Significant differences in biomass were found among populations: total weights of stems ranged from 5.0 to 21.5 metric tons per hectare, densities ranged from 45 to 219 colonies per hectare, and colony size from 4.6 to 9.6 stems. Regression equations were developed to predict aboveground biomass from plant measurements. Our results might support the development of management plans for the intensive use of wild populations of Y. schidigera in Baja California considering rates of harvest according to their density, structure, and biomass productivity.
