Thanks for the information concerning the dispute over the burros. Such arguments and disputes over deteriorating land, noxious plants/animals and disappearing wildlife are endless and global as I experience working in the US. Mexico, Canada, all over Africa, Australia, South America, etc. Frankly if we remove all emotion, institutional and professional egos and look objectively at nothing but the science neither side has the answers. Some of the points you are making are closer to the science but as you note are fueling conflict and disagreement that could continue for years.
