Thank you RedSquare. I guess what you are saying is to " set the 'Y' setting' to -3.5 in order to avoid having all the trees be partially covered by the terrain ...correct??? 
Maybe in part. But remember the displacements you have are fractal based and thus it's not an even displacement, but it varies from place to place. Setting the Y to -3.5 displaces the terrain evenly.

I tried to open the file; but, received error message: "TGO Reader: unable to open file".

Ah! there you are 3DGuy, so why does the minus Y and plus Y settings to the object area placement seem to work the reverse to what I was expecting?

Thanks 3D Guy; will do another render and check that out.

Yes, you will.  The same as everybody who downloaded your .tgd received the same message as above.

It's because the .tgd is referring to an object which isn't in the same place on your hard disk as mine.  Just go to your object folder and load the same model as I used over the top of mine and it should be OK.

I'm having some problems with this. I think I'll move the strata/outcrops in the file I'm working with. I'll get back to you after I work with this for awhile ...thanks again for all your input.

To be honest I have no idea. I tried to replicate that and created a new scene with a simple population. Now setting changing the Y value on the area didn't change anything for me. I guess this is due to the 'sit on terrain' option. However, entering a translation Y value in the object loader itself (transform tab), I was able to move the population up and down. A negative number pushes the population into the ground, a positive number raises it above the ground. It's weird that it would work in reverse for you.

I just checked my .tgd. I seem to have applied it to the Distribution tab of the object itself with the sit on terrain being checked.  So, I was obviously doing it incorrectly. Not so much a noob as a knob.  ;)  Ah me I sure as hell won't do that again.  Thanks for straightening me out.

I've been experimenting a bit more with this and have concluded the strata shader is the culprit here. Somehow it's information is not incorporated into calculate terrain option for the population shader to use. I even moved the strata node and placed it before the calculate terrain node and that didn't help. Disabling it puts the trees on the ground, enabling the strata node raises the ground but the population just doesn't see it (and yes I pressed repopulate ;))

This could well be a bug...

I suggested a couple of days ago to delete the population and start with a new population after all wanted adjustments have been made to the scene. Has anyone tried that yet?

There is another issue like that with the fractal detail on heightfields.  Placing a compute normal or a compute terrain node *should* fix it, but it obviously hasn't worked for you.  Other than that I don't think there is a workaround right now....

I'm comming in late to this topic, has the problum been solved?

The world is round... so you have to use spherical projection.
