I have a sound localization project that can help with that

You need to be able to hear the sound from three or more recorders. And normally localization is better within the polygon of microphones but there’s an area of better localizability extending outside of a vertex.

Do we really? Elk herds are fine. Seems like a waste of resources to have rhino-like enforcement for elk. Colorado has almost 300,000 elk.

Spend a significant amount of time in the state and get back to me about what's possible. I'll wait. Note you're talking about an area only slightly smaller than New Zealand with roughly identical population numbers to Santa Barbara County, 1 third of whom are either students at UWyo or migrating roughnecks with no dog in that fight. Ignoring the handful of millionaires clustered around Jackson Hole the rest of the population of the state are (taken in aggregate) heavily armed and utterly disinterested in the federal government's position on anything. You send a handful of well-intentioned game wardens from out of state into that mess and you're gonna have folks start disappearing.
