RLeeP has it right, when you start messing with private property rights you will see huge resistance. Since the majority of folks don’t fish, there is little chance a politician is going to risk reelection by pushing such an unpopular change.
That leaves tax breaks or purchasing easements. If you examine the history of the clean and green program, you’ll see the tax break idea has been tried and is now failing miserably. The basic problem was local politicians did not like their tax revenue declining so rather then raise taxes slightly on everybody else, they started chipping away at the clean & green program. Most recently eliminating streams, ponds, riparian buffers, access roads and the homestead from consideration. For me, if timber prices go up 5% I’ll be paying more taxes under clean & green then if I stayed out of the program and posted the land.
So our final hope is purchasing easements. This is the approach I prefer. As long as its funded by the people that benefit, anglers, we don’t run into the problem of resistant from folks that don’t fish. The other advantage is once an easement is purchased, its written into the deed and can’t be revoked if the property changes hands. The Erie stamp is an example. The PFBC already has nearly $1 million in that account. A similar program on a statewide basis could easily bring in $5 million a year. But we better get started soon, its just going to get more expensive the longer we fiddle. Just my 2 cents.
