Depends on what you want to do and at what scale:
for close up trees, use the plant editor to make them and place them by
hand or use Replica. For better efficiency, place primitives where you
want trees and then use Swap to replace them all with trees. Both
plugins by inagoni. Anything grows by digital carvers guild can also be
used to place trees as tip objects.
for distant trees use billboards: pictures of trees on planes oriented
to face the camera and with alpha masks to make the rest of the
billboard transparent.
For really distant trees, render out an image of a forest edge and put
it on a long billboard.
Or duplicate your terrain, add noise, paint on the map to lower the
noisy terrain in places where you do not want trees. Texture this
terrain with a green shader with noise in the alpha channel with the z
scale of the noise to be only 1 (may need to fiddle with it). A demo of
this technique is at http://www3.telus.net/pem/MountainTest.jpg and
http://www3.telus.net/pem/MountainTestShader.jpg shows the shader for
the mountain (but not the noise trees). This technique is in the Carara
3 Handbook by Mike Dela Flor
