Graphic showing potential benefits of RestoreNet 2.0 treatments, including seeding, live topsoil inoculation, livestock grazing, seed balls, and soil pits

An ecological site group map for the Upper Colorado River Basin that displays a quantitative soil-geomorphic framework in the Four Corners region, USA.

RestoreNet treatments include soil pits and connectivity modifiers (ConMods), seen here at a RestoreNet site in the Sonoran Desert.

Part of a series of small inset drawings, this is a top view of Havasupai Falls, its aquamarine colored water is highly recognizable and it is a site of tribal, cultural, and recreational significance to the greater Grand Canyon region.

Example graph of land cover calculations derived from remote sensing airborne image analysis for 0.1-mile segments of the Colorado River from Glen Canyon Dam to Diamond Creek. The percentage of the river valley covered by water (at 8,000 CFS river discharge), sand, vegetation, and other landcover are plotted for each 0.1-mile segment of the river.

Part of a series of small inset drawings, this is of a sign located near Horn Creek. The Creek is contaminated with high levels of Uranium. Sign states: "Horn Creek, Danger, Contaminated Water, Do Not Drink! Water in Horn Creek exceeds EPA health standards for radioactivity"

Created for a fact sheet on the implications of breccia pipe Uranium mining in the Grand Canyon region, this drawing packs a significant amount of information into a single image.
