ORC has 40 years of experience managing and assessing landscapes for broad biological values. Over the last eighteen years, ORC developed the necessary tools and metrics to quantify rangeland and riparian cover conditions by integrating remote sensing with ground sampling. This unique synergy between management experience and geospatial technology has led to a suite of products and services called EST. ORC has a diverse portfolio of successful sagebrush assessment projects that has encompassed over 40 million acres in 11 states. This includes 16 million acres of sage grouse priority habitat assessment and 1.2 million acres of invasive weed mapping and the prediction of new infestation areas. Also, ORC has assessed 2,197 miles of riparian areas in 7 states including habitat assessments for the endangered species of Lahontan Cutthroat Trout and New Mexico Meadow Jumping Mouse. ORC has mapped conifer encroachment on 1.5 million acres and wild horse assessment and carrying capacity of 2.5 million acres. Additionally, ORC has created tools for ranch planning including the “Piosphere Tool” and the tool for “Residual Dry Matter” mapping. The validation process for each of these projects has included extensive verification where ORC has collected thousands of grand samples. Validation has also included peer-reviewed articles as well as qualitative review by many public and private land managers that have evaluated EST relative to their experiences. Both the quantitative and qualitative validation suggests that the monitoring results are highly reliable and useful to managers.
