Money that flows from the people to the government is a tax. I get your point that hunting fees are a fairly appropriately scoped/targeted user fee, which is the best type of tax. But if the state owns the land and compels the payment of monies to support it, it's public land paid for with public money and I shouldn't have to get a permission slip to undertake lawful activities on it.
Again these WMA’s are paid for solely by land stamps, hunting, fishing, and sporting license fees , and in some cases they are “gifted” from private citizens so it’s only fair that if you want to use it you share some of the responsibilities of maintaining it
WMA’s are very different than state forest
Jane and Mary who ride their horses on the trails in the WMA’s and do nothing but bitch about the hunters and shooters don’t contribute at all to the area monetarily yet ironically pose the biggest threat
