What others have posted ought to be sent to every state DNR asking "why is this allowed to continue and what are they doing about it?" Granted some of these incidents are borderline ethics...but the vast majority are law violations.
The DNR is not "allowing" these violations to continue anymore than the local pd is "allowing" murder and theft to continue. And what are they doing about it? What they can given budget and law and human rights restrictions.
Important to remember in the US you are innocent untill proven guilty.
Sad to say, if you want the job done right you gotta do it yourself. You could depend on the occasional presence of a cop to keep your house from being broken into but we all know how that may end up. You come home to a trashed and burglurized house. Should of invested a bit of time and money into security. Best you can do is to continue to chase em off, put up signs, patrol, and what not, and then call LEO's or DNR for back up.
Here is some of what I've seen happen.
Many people report violations but it usually boils down to he said / she said(hard to prove) type things or speculation on who you think or know did it. But no hard evidence. Sometimes people don't report it at all. Sometimes by the time they get around to telling a DNR officer it has been hours, days, weeks, months. I can't tell you how many times people tell me something that happened or that they saw and I ask them when did this happen "OOOH I'd say about 3 weeks ago" or "Last year" I ask them if they reported it. "no" or "I just did, to you" (I work for DNR but not Division of Law Enforcement) Indiana has a hotline number for reporting any fish or wildlife violations(1-800-TIP-IDNR)
Also, CO's are stretched few and far. So when a call is made they are buisy with another or too far away to respond quickly enough. They spend a bit of time looking for lost hunters and scooping up injured hunters.
And, CO's to do not patrol into private property any more than a LEO will just amble around on your back porch and into the kitchen just to see if any law breaking is going on, During Deer season they usually only go onto public land to patrol if a violation has been reported (think about it- A CO comes tromping through the woods on the only day you have off to hunt, possibly ruining the day for you for the sole purpose of checking your licence and making sure your in compliance. I'd really hate to see the only deer of the season take off out of range when a CO shows up
)
Some what is being done: Indiana turn in a poacher hotline # (1-800-TIP-IDNR), variouse sting operations such as deer dummies for spotlighting and roadside poachers, Block exits from popular hunting areas for a check station, Respond as best they can to calls, education programs, and other things I can't think of right now but will probably remember later. Sometimes they hang out by your vehicle and wait for you to come back.
Oh, and some laws and regulations are just stinkin too hard or next to impossible to enforce.
Ok, I think I'm done for now.
ps..... CO = Conservation Officer
