Also kinda low res trees but i'm used to XFROG stuff due to 5 sample folders being included in the free Terragen 2. Also if you frequent the terragen forums you'll often see free trees in both the terragen ,tgo format and obj as that's the highest quality output from XFROG so if you just need trees surf the forums..ground cover stuff turns up as well often.

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
