Colorado abides by mixed land use, meaning that many of its parks are used both for recreational and consumptive activities - like trophy hunting.
While hunting small numbers of moose in the state may not seem to make an immediate difference, the impact may be more than hunters realize. A phenomenon called "selective harvesting" is often observed by conservationists who study trophy hunting. Trophy hunters value the biggest, strongest, large-horned animals which leaves a resulting population skewed toward smaller males and females. A domino effect ensues wherein females have fewer mating partners, and a demographic change in the population is seen. In one 2006 paper in the journal Conservation Biology that explains this phenomenon in moose populations, researchers wrote that the removal of even a few targeted individuals can have effects on the demographics of a population as a whole.
Conversely, moose-watching has blossomed into a popular and fruitful industry. In New Hampshire, moose tourism rakes in $115 million every year - and the moose probably like it a lot better than the sport hunting industry.
