Thank you, everybody, for the insight and references. Like lead into
gold, Larrea tridentata seems to be the right plant for the Gila tribe
to harvest. While there are some reports of deer herbivory, and seed
consumption and dispersal by packrats, everybody is describing a
species that's not only pretty abundant, but with increased
desertification in the southwest a population that's spreading. <br>
