Can anyone recomend any tutorials for modelling trees through blender, i dont want to use a pre made program to create trees, i ran across a few tree tutorials in the forums but cant find them now 
Any tutorials on trees, landscapes, vegetation etc that will work in the blender GE too would be great 
thank you!
Cheers!
I can tell you how to make grass:
Make a plane, give it a grass texture, go to F7 - >Particles buttons > Particle System and add new Hair, then mess around with the Physics and other settings like the Amount or so, then when you are finished convert the grass to mesh ( Alt+C ) and there you go, a nice grass
For trees:
Quck mode - http://www.geocities.com/bgen3/
Slow mode:
Add a cylinder and extrude it till you get your main trunk, then add another cylinders and play with them until you get some, join the branches and trunk ( Alt + J or Ctrl + J or Shift + J ) and add a nice wood texture.
For leaves maybe you gotta shape little planes into leaves add some texture and then duplicate them as much as you want.
Of course theres a better way for leaves making by using specular mapping i think about which you just gotta look up in google.
