Foraging is the skill of living off of the land.  Only certain of the woodsier classes and races are able to forage.   Thus, Rangers get the skill at level 3,  Druids at level 5 and Bards at level 12.   Also, Wood Elves and Iksar have the inherant ability to forgage  You start off your skill at level 50, and only Rangers and Druids are able to increase the skill.  Most of the items you can scrounge up are only good for eating and drinking, but will at least save on your muffin and milk budget.  Many of the special foraged items can be sold to a vendor for about a gp, so you can earn some money through foraging once you reach level 19 and can forage special items.  Some of the items are also useful in conjunction with other skills such as brewing and possibly baking.  There are basic foraged items that can be found in almost every zone such as grubs (yum).  Other items are more zone specific.  The zone-specific items can't be foraged until you reach a 100 skill level (except in Kunark - see below).
