Legume trees have been harvested in the Sonoyta Valley since 1975. We estimated the effects of this woodcutting along the border between Organ Pipe Cactus National Monument (U.S.A.) and Sonora, Mexico. We placed 10 X 100 m transects in ephemeral watercourses and uplands on both sides of the international boundary at different distances front the border. Mesquite and ironwood trees exhibited significantly higher damage in the Mexican sites than in the protected uplands in the United States. Damage for all the species significantly decreased 500 m from the border, with the exception of ironwood, for which damage remained high within ephemeral watercourses.
