Eastern Spruce Fir Large - this Blended Background should be used with my Eastern_Spruce-Fir wide cover spline or these trees which make up the spline: Balsam_Fir_10, Black_Spruce_10_20m, Canadian_Hemlock_10, Northern_White_Cedar_10, Paper_Birch, Tamarack, White_Spruce_1, White_Spruce_2, White_Spruce_3, Yellow-Birch_summer . 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.
