Eastern Elm Ash Large - this Blended Background should be used with my Eastern_Elm-Ash wide cover spline or these trees which make up the spline: American_Elm-13, American_Elm-18_30m, American_Elm-20_20m, American_Elm-21_20m, American_Elm_6, cottonwood_2, cottonwood_4, RedMaple_Summer, sycamore_1, Undergrowth_6-2, White_Ash, White_Ash_2. 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.
