AbstractThe mesquite-harvesting project at the University of Arizona was in practice from 2011-2013. During the development of the project, students, faculty, and staff were engaged in harvesting, designing harvesting methods, milling, baking, researching, and selling mesquite flour at the campus. After discovering a common toxin in mesquite-pods, a strict harvesting method was obtained and followed throughout the seasons. However, because of the high-maintenance process of harvesting, the mesquite-harvesting project at the University of Arizona could not economically sustain on campus, and therefore, had to come to an end. This document explains the process of harvesting, the research of aflatoxin, best practices, and other events that happened during the UA mesquite-harvesting project.

Mesquite Twig Girdler: A Possible Means of Mesquite ControlUeckert, D. N.; Polk, K. L.; Ward, C. R. (Society for Range Management, 1971-03-01)The mesquite twig girdler (Oncideres rhodosticta Bates) was found to inflict considerable damage to mesquite in Texas and may prove to be a valuable biological control agent for this noxious species. Preliminary observations in infested areas indicated that about 90 percent of the mesquite trees had been attacked by the girdler and that about 40 percent of all branches from 0.5 to 2.0 cm in diameter had been girdled.
Botanical Composition of Steer Diets on Mesquite and Mesquite-Free Desert GrasslandGalt, H. D.; Theurer, B.; Martin, S. C. (Society for Range Management, 1982-05-01)Botanical composition of cattle diets on mesquite and mesquite-free desert rangeland was determined on a weight basis by a microscope point technique and density constants of species. Pastures consisted primarily of grasses, small amounts of forbs and shrubs, and velvet mesquite (17% crown canopy) on one unit. Dietary composition of plant groups consisted of 67 to 97% grasses, 0 to 4% forbs, and trace to 33% shrubs. Species composition of diets varied by seasons and among animals. Plant preference was not necessarily related to plant availability. Composition of diets was markedly different from composition of pastures. Black grama averaged only 3% of diets, but comprised about one-third of herbage production. Arizona cottontop, which averaged 20% of herbage on pastures, was the most consistently selected species, averaging 34% of the diet. Seasonal preference was shown for certain grasses such as rothrock grama in spring and bush muhly in winter. Highest preference for shrub species was shown in winter and early summer. Overall dietary composition between pastures was much the same, but average herbage production for a 2-year period was 347 kg/ha greater where mesquite had been controlled. Leaves comprised the major plant part of steer diets on both pastures. Leaf content of diets increased from winter to summer while stems decreased for the same periods. Botanical composition of animal diets can be a guide to more efficient use of the range resource by grazing animals.
