Here's one difference:

According to IDNR Indiana fields about 225,000 hunters during the deer season, roughly 25-30% of them actually take a deer. IDNR gets a huge share of it's operating revenue from hunting licences and the Pittman-Robertson tax on hunting gear.

Crop damage permits are issued free of charge by the local district biologist to landowners who can show at least $500 in crop damage , 96% of which get filled. No revenue is generated, but the herd is further reduced at a time where it will be most effective since any doe killed probably has at least two fawns which will also die.

Both are culling attempts, and part of the state's overall game management plan. The one thing I would change would be to make the crop damage permits "antlerless only".
