Qualifications
Believe it or not, a sense of oneness with nature does not guarantee a career as a game warden. Remember, at its very base, this is a law enforcement position, akin to police officers and state troopers. You're not just a glorified scout master playing rent-a-cop; conservation officers are necessary and respected authority figures.
You'll be carrying a gun and a badge, so at the very least, you'll be required to attend a training academy. The duration of training varies by state, and to work for the Federal Government, applicants must take an additional twenty-week session.
But that's just the law enforcement part; there's also the everything-else part of your job. A bachelor's degree is expected, so don't expect to be sent out into the wild armed with only a high school diploma. You'll have to specialize in criminal justice or wildlife conservation. Knowing how to drive an off-road vehicle or a boat can also come in handy.
Animals will be a huge part of your workday as well. This is where getting a college degree comes in. You'll be expected to track them, study them, rescue them, and occasionally put them down. We know that last part is kind of a bummer, but it's kind of a bigger bummer when a group of schoolchildren get mauled by a rampaging mountain lion.
You're also really going to need to love the outdoors, so being a Boy or Girl Scout actually is a helpful first step. Typically, unless you're warden for a zoo or game preserve, you're helping to conserve wildlife in its natural habitat. This means being okay with working in said natural habitat. Academy training shouldn't be your first day in the woods.
Basically, if you've been swinging from treetops like an American Tarzan, then this career could work, and if you think a slip knot is a type of heavy metal band, this might not be the right career for you.
