A quick opinion about getting lost in the woods. Rangers and Druids should never get lost unless something or someone royally Fs up.
A ranger would have solid orienteering skills and even in unfamiliar territory would be able to locate north/south, prevailing wind conditions, places of high/low sun, key lines which water flows down as well as where to look for water, as well as significant spots they'd passed thru before, significant animal trails, lookout perches, bird behavior indicating human presence, and that it's wiser to hunker down in bad weather especially in unfamiliar lands. These are pretty fundamental orienteering skills, nothing fancy.
Now multiply that by a medieval fantasy amount of "dirt time" and magic, and a ranger getting lost should be on the far outlier of wilderness challenges.
I think some folks make too much of the wilderness. It's plants and trees and animals that want nothing to do with you. Sure, I've almost stepped on a few deer, but most folks make too darn much ruckus long before they get to the animals. I've never known anybody who got attacked by an animal. So animal combat encounters are virtually out.
Note: in Colorado, or whatever place has all the dang bears that maul people, you'll note that the head count is high, and the people have food. that's a special situation. I've seen two bears or so. Once in a field, from the window of my house, and once in a car on my way home from prom. they ain't exactly common.
I'm not even a huge wilderness guy. Put a ranger in the party, and we're about as safe as can be, like quickleaf says.
I wouldn't discount that there can be some dangerous PLACES, where heat, cold, lack of resources, or collapsing terrain could do you some trouble. But animals? meh.
Note: In Texas, assume every spider or snake can kill you. There's only really 2 of each, but if you can't tell them apart.... Also, I suspect animals in North America are downright tame. In Australia, every other animal is poisonous. Africa has lions and tigers which are pretty tough as well.
I still suspect that the standard D&D party wearing the standard gear would clunk around and scare off most of the mundane animals and be pretty safe from them.
