In 2017, the Humane Society of the United States (HSUS) released a report titled “State of the Mountain Lion—A Call to End Trophy Hunting of America’s Lion.” In the report, HSUS calls for an end to mountain lion hunting in the United States based on several scientific arguments. These arguments range from citing available literature on demography, ecology, and sociality of mountain lions, to the protection of potential habitat and population sizes across 16 states where breeding populations exist.

By John Organ — Polygamous species include those we are quite familiar with: whitetail and mule deer, elk, and moose, where one male may breed several females. Polygamous cervid species display what biologists term sexual dimorphism, meaning the two sexes exhibit differences in some physical features. In the case of cervids, this is represented by males typically having larger body size than females. This is true of many species of mammals that are polygamous.

By John Organ — Nearly 100 years ago Aldo Leopold, the father of game management, coined the term “harvestable surplus.” The intended meaning of the term is that some wildlife species and populations may produce more young in a given year than can survive to the following year. Those individuals doomed to die over the winter, for example, represent the “surplus” in the population. Leopold observed that those surplus animals could be killed by hunters during the fall, instead of succumbing to winter mortality, and there would be little impact on the population. So, in theory, hunting would be sustainable because the population would not change.

By John Organ — The issue of lead versus non-lead ammunition has been a divisive factor within the hunting and wildlife conservation community for decades. Consider this statement: “The accounts of the destruction of ducks, geese, and swans by lead-poisoning which are printed on another page bring to public attention a new element of danger to our wildfowl, and one for which a remedy will be hard to find.” This was written by George Bird Grinnell, co-founder of the Boone and Crockett Club in 1894.
