since hunters and fisher pay their license, hunt-lottery and other fees to states. Federal migratory bird stamps, taxes on guns, fishing equipment, motorboat fuels, etc., are collected by the Feds.
In Texas, some $105,000,000 is collected from hunters/fishers; yet only about a third is expended on the Parks and Wildlife Department, here. The rest of the license and other use fees go to the general fund. And this state "formula" does not include, I believe, Pittman-Robinson funds; that is added in later.
Often overlooked are the many wildlife management areas in Texas whose wildlife operations are supported by hunters/fishers. Some, like Granger WMA, can be used by hunters who pay a $48 public hunting permit, yet fishers, bikers, etc. are not charged.
Though I have no links, some years ago there was a campaign among non-hunters/fishers in Texas to pay for hunting/fishing licenses anyway, as this was the only thing "floating" the nearly foundering parks and wildlife department. Things are still bad for funding, but may get better next fiscal year.
