Rangers, Druids and Bards get forage as a class skill.
Wood elves and iksar get forage as a racial skill. Racial skills are usually capped at 50. You start at that level and never increase.
A Wood elf ranger or druid would start at 50 and then start increasing in skill once they reach the level for skill increases to begin. Ie they would have to be level 9 or greater.
I do not believe that Vah Shir get forage, unless of course you make a vah shir bard.
