A fractal terrain here dressed with shrubs, grasses and The Noble One tree by 'Walli'. Additionally, the surface uses Ryan Archer's 'Dirt' file; and, the 'Mackeral' clouds are those created by Matt Fairclough - creator of Terragen 2. The dry shrubs were re-colored using a different color/texture file. They resemble the 'Jojoba' bush which is plentiful out here.
The grasses, shrubs and dirt files are available at the NWDA site. The tree and cloud files are available at the Planetside forum.
