On Sims 2 Castaway for PS2 where do you find hardwood?

I've been looking EVERYWHERE and I can't find it.Somebody said it was the palm tree;but that turned out to be false.Someone else said it was a teak tree or something but I don't know where that is.I need SPECIFICS,like left of this or right at that.Seriously.I want the Island,the location on the island, and where to turn.If anyone could help me I'd really appreciate it.
