    • Ecotypic variation in Ambrosia dumosa and Larrea tridentata from three sites across the Mojave (2014 - 2018)

    Metadata Updated: October 29, 2025

    These data were acquired from two native Mojave Desert species, Ambrosia dumosa and Larrea tridentata, from 3 sites (50 m x 50 m garden plots) distributed across the differing Mojave Desert ecotones. These sites were located on the Fort Irwin National Training Center (CA), north of Joshua Tree National Park (CA), and north of Saint George (UT). Growth and survivorship data were collected monthly from 2014 to 2018. Canopy projection data was calculated from the measurements using the mathematical equation: pi x 0.5 x L1 x 0.5 x L2, L1 is the longest diameter, L2 is the perpendicular longest diameter (cm squared). Height was measured from the ground to the tallest green leaf (cm).
