"basic"? Looks like it's Esprit. When you say the leaves move, how do they move? Only the leaves move, and not the trunks? Could it be that in the material editor of your plants you entered values in " origin of material" and "velocity of material"? These values are found in the "effect "tab of the material editor.

If so, your textures are animated. If not, I really don't know what's happening!
