Problem creating forest with particle system

I built a tree trunk then added the branches using a particle system, so far so good. When I go to use the tree in a particle system to make the forest, only the trunk shows up.

I tried using the convert button but that doesn’t seem to do anything. I am using the latest blend.

never mind. I figured it out: use the convert button on the forest floor, not the tree itself. Do I feel silly!
