In 1992, he was also appointed Director General of Natural Resources in the Mexican Federal Government. Born in Argentina, Ezcurra moved to Mexico early in life. He completed his higher education at the University College of North Wales, Bangor, where he received a master's and a doctorate in plant ecology.
