303(d) list of impaired water bodies
The list of impaired and threatened waters that the Clean Water Act requires all states to identify. This list specifies where required pollution controls are not sufficient to attain or maintain applicable water quality standards, and helps establish priorities for development of total maximum daily loads based on the severity of the pollution and the sensitivity of the uses to be made of the waters, among other factors.
abundance

Recreation features installed and maintained by the Forest Service, or historical structures used by visitors. These facilities include toilets, picnic tables, bear poles or other food storage structures, permanent fire rings/ grates, shelters, developed water sources, corrals for recreational stock holding, large bridges, and Forest Service-constructed tent pads or sleeping platforms.
baseline conditions
The starting point for assessing change over time without value judgment as to whether these conditions are good, bad, or desired. best available scientific information: Scientific information which each local wilderness unit is required to use for all selected measures. Determined by subjective evaluation of data quantity, quality, and adequacy by resource specialists for all potential data sources considered for each measure. “Available” refers to information that currently exists in a useful form, and that does not require further data collection, modification, or validation. If the only available data are insufficient in quantity, they may still be considered the best available scientific information for the local unit. In general, the highest quality data will be considered the best available scientific information.
biophysical environment

camp encounters
The daily mean number of camping groups visible or audible from a visitor’s campsite during the primary use season.
central data analyst
A Washington Office staff position that is responsible for gathering the data from national-level monitoring programs, e.g., the Forest Service Air Resource Management Program, and preparing these data and then entering them into the WCMD for each wilderness. This position is also responsible for consulting with a statistician to determine the appropriate type or form of regression used for statistically analyzing trend in the measures.
change management process

cherry-stemmed roads
A road or trail that is excluded from a wilderness by a non-wilderness corridor with designated wilderness on both sides.
Class I area
Areas of the country protected under the Clean Air Act and afforded the opportunity for the highest level of air quality protection. As defined by the Clean Air Act, Class I areas include the following areas that were in existence as of August 7, 1977: national parks larger than 6,000 acres, national wilderness areas and national memorial parks larger than 5,000 acres, and international parks.

cumulative effects
The impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (federal or non-federal) or person undertakes such other actions. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time.
dam
Any artificial barrier, including appurtenant works, that impounds or diverts water, either temporarily or long term.
data accuracy

data quantity
The level of confidence that all appropriate data records have been gathered; classified as "complete," "partial," or "insufficient."
deciview
The unit of measurement of haze. Deciview is a measure of visibility derived from light extinction that is designed so that incremental changes in the haze index correspond to uniform incremental changes in visual perception, across the entire range of conditions from pristine to highly impaired. The haze index (in units of deciviews [dv]) is calculated directly from the total light extinction.
decommissioned
A road that has been withdrawn from service. Decommissioning is defined as the “Demolition, dismantling, removal, obliteration or disposal of a deteriorated or otherwise unneeded asset or component, including necessary cleanup work” (Financial Health–Common Definitions for Maintenance and Construction Terms, July 22, 1998).

meaningful change
The amount of change in the data that would result in a change in trend for a measure. Thresholds for meaningful change are defined for each measure. Meaningful change in a measure is not directly tied to, or based on, a national forest’s land or resource management plan, nor does it represent significant change or impacts as defined by NEPA.
measure baseline year
The first year that data for a measure have been compiled; the reference point against which the trend in a measure is assessed and evaluated.
measure value
The single value produced for each year of data compilation for a measure; this value is used to derive the trend in the measure. For measures that use an index based on an annual or 5-year frequency of data compilation and analysis, the index value is the same as the measure value. For measures that use an index based on a 3-year rolling average, the index value is calculated each year and the measure value is the 3-year rolling average.
measures
The specific elements under each indicator on which data are collected to assess the trend of each indicator of each wilderness character quality; data compiled for a measure must be relevant, reliable, and cost-efficient.
mechanical transportation

minimum requirements analyses (MRA)
Analyses designed for use when making a determination that one of the 'prohibited uses,' listed in Section 4(c) of The Wilderness Act of 1964, is the minimum necessary requirement. The determination that an administrative action is necessary in wilderness and the selection of the minimum method or tool to be used is made within the constraints of law and agency policy. Once a determination has been made that action is necessary, Forest Service policy sets conditions under which exceptions to the prohibited uses (e.g., motorized equipment, mechanical transport) may be considered and guidelines for when the exceptions should be applied.
monitoring questions
Questions which capture the essential components of each wilderness character quality that are significantly different from one another and address specific management questions and monitoring goals.
motorized equipment
Machines that use a motor, engine, or other nonliving power sources. This category includes, but is not limited to, such machines as chain saws, aircraft, snowmobiles, generators, motor boats, and motor vehicles. It does not include small battery or gas-powered hand-carried devices such as shavers, wristwatches, flashlights, cameras, stoves, or other similar equipment.

prescribed fire
Any fire ignited by management actions under certain, predetermined conditions to meet specific objectives related to hazardous fuels or habitat improvement. A written, approved prescribed fire plan must exist, and National Environmental Policy Act requirements must be met before ignition. Prescribed fires are ignited and managed within a “window” of very specific conditions, including winds, temperatures, humidity, and other factors specified in the burn plan.

QA encompasses the plans, specifications, and policies affecting the collection, processing, and reporting of data. It is the system of activities designed to provide officials with independent assurance that quality control is being effectively implemented uniformly throughout the inventory and monitoring programs.
quality control (QC)
The routine application of prescribed field and office procedures to reduce random and systematic errors and ensure that data are generated within known and acceptable performance limits. QC involves using qualified personnel, using reliable equipment and supplies, training personnel, and strictly adhering to service-wide standard operating procedures for tasks such as information needs assessments, establishment of standards and methods, data collection, data processing, classification, mapping, analysis, and dissemination.
recreation site
A place where visible impacts to vegetation or soil are documented as a result of repeated recreational use.
regression
A commonly used statistical technique to determine if there is a significant change in one variable, for example, the amount of nitrogen deposition or the number of trammeling actions, in relation to another variable, such as time over several years.

unconfined recreation
A type of recreation in which visitors experience a high degree of freedom over their own actions and decisions. This encompasses the sense of discovery, adventure, exploration, and mental challenge presented by large wildernesses in which one can travel widely and explore unique and unknown environments on one’s own without having to conform to society’s norms or rules.
Undeveloped Quality

Utility infrastructure is classified as "small scale" (an individual site occupying less than one acre in total size), "moderate scale" (either (a) an individual site that equals or exceeds one acre in size or (b) requires an above-ground linear corridor, but is of a generally small scale, typically less than a half-mile in length), or "large scale" (requires an above-ground linear corridor, but is of a generally large scale, typically equal to or greater than a half-mile in length).
watershed condition
The state of the physical and biological characteristics and processes within a watershed that affect the soil and hydrologic functions supporting aquatic ecosystems. Watershed condition reflects a range of variability from natural pristine (functioning properly) to degraded (severely altered state or impaired).
watershed condition class
Within the Watershed Condition Framework (WCF), this describes the watershed condition in terms of discrete categories (or classes) that reflect the level of watershed health or integrity; classified as Class 1 = functioning properly, Class 2 = functioning at risk, or Class 3 = impaired function.

wilderness
“A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain. An area of wilderness is further defined to mean in this Act an area of undeveloped federal land retaining its primeval character and influence, without permanent improvements or human habitation, which is protected and managed so as to preserve its natural conditions and which (1) generally appears to have been affected primarily by the forces of nature, with the imprint of man's work substantially unnoticeable; (2) has outstanding opportunities for solitude or a primitive and unconfined type of recreation; (3) has at least 5,000 acres of land or is of sufficient size as to make practicable its preservation and use in an unimpaired condition; and (4) may also contain ecological, geological, or other features of scientific, educational, scenic, or historical value.” (1964 Wilderness Act, Public Law 88-577, Section 2c).
wilderness character
“Wilderness character is a holistic concept based on the interaction of (1) biophysical environments primarily free from modern human manipulation and impact, (2) personal experiences in natural environments relatively free from the encumbrances and signs of modern society, and (3) symbolic meanings of humility, restraint, and interdependence that inspire human connection with nature. Taken together, these tangible and intangible values define wilderness character and distinguish wilderness from all other lands.” (Landres et al. 2015).
