Western Fir Spruce Large - this Blended Background should be used with my Western_Fir-Spruce wide cover spline or these trees which make up the spline: Co_Blu_Spruce2, Co_Blu_Spruce5, Engelmann_Spruce_5, Lodgepole_Pine_5, Mountain_Hemlock_10, Mountain_Hemlock_12, Undergrowth_6-2, White_Fir_7. I used built in British ground textures in building the backgrounds and they should match the background pretty well. There is a tutorial on my site about how to use this Blended Background to best advantage.
