Please tell me more, entertain me. I love this thread. Again I'm not in Alaska but I am in a part of a state who live with deer and on the Northern central part of the State live with constant bear...
I lived in Alaska for a while, Kodiak, specifically. The large airport there was shared by commercial flights, private aircraft and the USCG. USCG flew C-130's out of there, as well as helicopters, falcons and occasionally other stuff. I used to periodically catch rides on C-130's for trips out to other places. Since the airfield was so large, and touched the ocean, fencing it in wasn't a realistic option. They would occasionally have to run out there in a pickup truck and scare the bears off the runway. Kodiak brown bears are large and don't give a flying flip about your little fence. They do what they want, where they want, and when they want. Man and bear share a slot on the food chain. Sometimes they eat us, sometimes we eat them. Bears also don't know how to fly and don't understand aeronautics, so they are not as sharp as some people seem to think when it comes to the happenings around airports. No doubt someone has made an attempt to properly train the bears, but it sure seems like maybe they forgot. Anyway, running them off with a truck usually helped them remember for a while.
Like I said, I used to catch rides on them. That usually meant I was flying somewhere else. That somewhere else was often a little speck of rock out on the Aleutian Island chain, or the Pribloff Islands. Not may bears out there but other critters that were large and didn't understand VFR. Pickup trucks, snow mobiles or snow cats were often used to educate the animals regarding right-of-way on the airfield.
The other thing we had issues with was seal lions. Often we had markers on small islands so as the ships would mostly avoid running into them. The sea lions would like to share those small rocks sticking out of the water with our aids to navigation. They were happy there, I guess they enjoyed the flashing green or red lights, or maybe the soft glow of the white lights was romantic or something. Anyway, said aids to navigation periodically needed maintenance. Landing a crew using a small boat on said small rock usually was met with much laughter from the sea lions. They felt the odd looking bipeds in the orange suits looked funny, and they really didn't take us seriously. The loud honkolator on the top of the ship usually didn't annoy them enough to move. The solution was for one of the funny looking bipeds in the orange suits to take a "bang stick" and annoy the crap out of the sea lions. That usually worked, however, scaring the crap out of sea lions resulted in a lot of, well, crap. Not to mention sea lion juices. Said crap and bodily fluids was pungent and offended the humans, but the guy with all the stripes said we had to work on the light anyway and that we'd get used to the smell (we didn't, it was a lie).
In Alaska I learned rather quickly that man isn't in charge, and no matter what we though or how we tried to fool ourselves into thinking it, it just wasn't so. We are but specs in the larger scheme of things. Bobbing around in the Bering Sea in the middle of winter and watching the aurora borealis makes you feel mighty small and insignificant, but that can be a wonderful experience and it teaches one humility.
