Description: The Recreation Opportunity Spectrum (ROS) is the land classification system the Forest Service uses to describe recreation settings and opportunities across forest lands. ROS has six distinct classes in a continuum (primitive, semi-primitive non-motorized, semi-primitive motorized, roaded natural, rural, and urban) ranging from primitive and undeveloped settings to highly modified and developed settings. The level of access, development, and social encounters increases when moving from primitive to urban on the spectrum. The level of remoteness and solitude increases when moving from urban to primitive on the spectrum.The GMUG’s existing ROS was inventoried and mapped using the Forest Service’s National Recreation Opportunity Spectrum Inventory Mapping Protocol, a geographic information system (GIS) mapping procedure that identifies mapping criteria and provides repeatable instructions to inventory, map, and classify existing ROS settings. This National mapping protocol is used to reduce variations within and across Forest Service administrative boundaries and helps the agency effectively communicate recreation settings and opportunities on the Forest to the public.Using existing inventoried ROS as a starting point, the GMUG developed preliminary draft desired ROS based on public comment, expert opinion, best available scientific information, and a need to address issues (FSH 1909.12 Chapter 20, section 23.23)
