This man has been making mescal out of Agave cupreata in Acateyahualco, Guerrero for a long, long time. Counting agave plants never used to be part of this process. But, after all of the meetings and presentations and discussion, he felt that running transects was probably something that he should know about - so he joined the inventory team. [NOTE: I got this marvelous image from Biol. Ivan Ibanez Couoh, who successfully defended his bachelor's thesis on the population dynamics of A. cupreata at the University of Guerrero in Chilpancingo this afternoon. Felicidades y gracias, Ivan].
