foraging classes and racesFollow

I want to start a new character for the purpose mainly of foraging as my main cannot forage. I can't locate a site or list that tells me which classes/races have this skill. I'd like to research it a bit before getting on to create the character. Any suggestions?

Foraging page from this site. Look at the top for the races/classes. Jophiel covered them all, this just gives a bit of additional info.

I don't quite get the logic behind why a bard would be able to forage, but not some of the other classes. I would think that ANYONE should be able to recognize and find some basic food stuffs (roots, berries, veggies). I understand why some classes and races would be able to forage better than others...but can anyone explain the logic behind most races/classes not being able to forage at all? I'd think short races would be particularly good at foraging roots and mushrooms :)

(And yes, I know I'm taking a game way to seriously here. But so many tradeskill items are foraged, it makes tradeskills, especially baking, much more expensive for non-foraging people.)

Admittedly my skill is pretty low IRL lol ...but even though I was raised in a major city I can recognize mint, blackberries, wild onions, and wild strawberries. And if I ever had the need or desire I could learn more.
But still..I'm curious...why can a bard forage and not a shaman? A shaman can learn alchemy, so must have a great deal of knowledge about various plants. Why can wood elves forage, but not, say, ogres? Won't an ogre eat just about anything? And what IS it about a bard that makes it possible for them to forage? Does their music make edible food just leap into their hands or something? I'm not griping, I'm just curious =)
