I figured out how to separate the vegetation and ground points. However, if we could look back at my first question on how to make a DEM. I created the DEM of the ground points, but I am having problems with snapping the vegetation points back. When I fuse/merge the two clouds together, there is no merging action happening. The window that shows which cloud you selected combines the two. Unfortunately, I cannot show you a picture of what it looks like because the file is too big.
