PARRISH, Ala. — It is easy to stop in a back room of Brady Johnson’s home and miss the bowls of individually wrapped peppermints and oatmeal cream pies.

There are the seven mounted deer heads and an even larger collection of antlers, including some crowded into cartons on the floor. Boxes of Winchester and Remington ammunition sit in the open. Plastic containers hold shell casings from such moments as when, in November 2000, one of Mr. Johnson’s sons took his first shot at a deer. (He missed.)

For Mr. Johnson, a 43-year-old firefighter and father of seven, the room is a catalog of a life often spent in the woods of the Deep South. But it also reflects a lifestyle that he worries is threatened by a slow-moving tide of regulations, like buck limits and restrictions on hunting with dogs, which he fears will curb the ability of his descendants to hunt.

Skeptics say the evidence is slim that Alabama’s predominantly conservative Legislature poses much of a threat to hunting. But on Tuesday, Mr. Johnson will be among the Alabamians to vote in favor of Amendment 5 to the State Constitution, which would “clarify that the people have the right to hunt, fish and harvest wildlife subject to reasonable regulations that promote conservation and management of fish and wildlife and preserve the future of hunting and fishing.” Mississippi voters will consider a similar proposal.
