Looks like what Luke Towan does

As for the pine trees, it sure looks like what amazing modeler Luke Towan does.

For the bark, he paints the wooden tree trunk with a brown spray paint.  Then, he sprays it with 3M spray adhesive and sprinkles Woodland Scenics fine "soil" color ground foam.

Hope that helps

Embed the Photos

Nelson, it helps to embed photos directly onto your post (rather than just a link).  It's quite simple once you've done it a time or two.

Lots of methods

Nelson,

I have built about 100 big pine trees and have experimented with a variety of methods to create good looking bark. I currently coat the trunk first with thin coat of light spackle - thin this down and paint it on. This will give a nice texture to the trunk. Next it is a wash of grey and orange acrylic paints over the spackle. I will also use the polka dot method wherein you apply little dots of black, orange white and grey over the trunk an then hit it with the orange and grey washes.
 

The trunk also matters - I use sticks from the forest for some tree trunks and if you are lucky the bark on the stick will work in your favor to create an interesting texture. Ken Larson wrote a great article on this topic in the August 2006 RMC - his pines are some of the best I have seen anywhere.

The trunk in the left of this photo uses the methods described above. I have lots more on the topic - send me a private message and I can expand further.

The bushes are noch leaves on super tree material.
