You could turbulate an isosurface object by using it's function in a 
pigment function, and using the pigment function for the actual 
isosurface.

#declare TreeFn =
function {
    pigment {function {...}// use the tree function as pigment pattern
        color_map {[0 rgb 0][1 rgb 1]}
        warp {
            turbulence 0.35
        }
    }
}

isosurface {
    function {TreeFn(x,y,z)}
    ...
