Thanks guys!
SSpanzer:
The jungle is made up different kinds of material:
The groundwork is made up of flowerpot soil and ordinary green foilage that you bye in an ordinary hobby store (Manufacturer: Woodland scenics "Cump foilage").
But most of the bushes are made from different kinds of moss that I found in the botanical garden in my neighbourhood. The moss with the lighter green tone is quite common, but the one with threads I found in a tree - a bird had made a nest of it during the summer (now empty), and had used the moss for building it. There it had been expose for sun, rain and wind that had dried it out and it gotten quite a dry, "wethered" look.
The barren tree in the dio is a root from small tree that I found in the woods - they come in handy when working in this scale.
The tree next to truck is a small plant I found groving between the pavement and the road. I find that plants that have grown in a narrow spaces - for example besides the pavement and between stones - often makes good material for trees and bushes in this scale. They became like small bonzai trees!
Hope that helps.
