Summary	The Recreation Opportunity Spectrum (ROS) is a framework for planning and managing outdoor recreation by classifying the landscape into a graded range of settings, from primitive to modern and urbanized. Articulated by Roger Clark and George Stankey for the USDA Forest Service in 1979, ROS rests on the premise that the quality of a recreation experience depends heavily on the setting in which it occurs, and that a recreation system should deliberately provide a diversity of settings so that different visitors can find the experiences they seek. The framework defines settings along physical, social, and managerial factors, such as remoteness, the density of other visitors, and the degree of on-site regulation and development. By inventorying these factors and combining them, managers classify each part of a landscape into an opportunity class and then prescribe management consistent with maintaining that class.	Tourism carrying capacity assessment estimates the maximum level of visitor use a destination or site can sustain before its environment, infrastructure, host community, or visitor experience begins to deteriorate unacceptably. The concept, given its influential tourism formulation by A. M. O'Reilly in 1986, recognises that carrying capacity is not a single number but a set of limits operating across distinct dimensions — physical and ecological capacity on the resource side, social capacity on the host and visitor side, and economic capacity on the activity side — with the binding constraint being whichever is reached first. Carrying capacity is the conceptual engine behind Butler's Tourism Area Life Cycle, explaining why unmanaged growth leads to stagnation, and it underpins much of sustainable destination management even as it has been refined into more flexible, indicator-based frameworks.
