If hunters and trappers were valuable service providers for landowners, then they would be the ones getting paid to hunt and trap. We all know that this is very much not the case.
@elk yinzer, I think you're very right that switching from meat having value to recreation/trophies/tournaments having value has definitely thrown a wrench in the works. We're struggling something fierce in Alabama to figure out how to manage todays super-successful bass fishing tourney crowd. Historically, you managed harvest with creel limits. A small percentage of anglers are so good at finding big, breeding bass, that they're literally (according to DCNR and an AU study) catch-weigh-and-releasing them to death. There's a big fight over if we're going to start limiting/banning tournaments on less-fertile reservoirs, implement a season instead of allowing year-round fishing, try to stock our way out of the problem, or (gasp) switch to catch-photograph-release.
