The difference between macro and micro management. Its hard on many fronts (cost, logistics, public willingness, etc) for states to manage herds in a micro management way. Yes its unfortunate that some localized (micro) herds that can be negatively impacted but as long as the entire herd throughout the region (macro) are not negatively impacted then great. This plays into the source/sink dynamic. Most states will manage to carry a herd above carrying capacity (k) just in case of unforeseen mortality (ie winter, predators, etc). This can allow for no change in quota for hunting licenses, unless the herd is negatively impacted in a severe way or hit multiple years.
