Final Environmental Impact Statement Rio de los Pinos Vegetation Management Project tree age under 200 years for softwoods and under 100 years for hardwoods. Canopy closure is greater than 40%. b) Stand dominance by trees in the 5” DBH or greater size with tree age over 200 years for softwoods and over 100 years for hardwoods. Tree crown cover is over 70%. Indicator: A measurement of a resource quantity or quality, which is linked to a cause-and-effect relationship and responsive to a Key Issue. Indicators are used to compare the effects among alternatives, and are most generally quantitative, rather than qualitative, in measure. Key Issue: A concern expressed over the potential effects of a proposed action on the human environment, due to the geographic extent, duration, or intensity of interest or resource conflict. Key Issues are used to develop and compare alternatives, prescribe mitigation measures, and analyze the environmental effects. For an issue to be considered Key, it must be relevant to the specific project and appropriately addressed at that level. Landscape Character: An overall visual and cultural impression of landscape attributes; the physical appearance and cultural context of a landscape that gives it an identity and “sense of place.” It includes existing land use patterns, ecological unit descriptions, and existing landscape character descriptions. Landtype Association: An ecological mapping unit based on similarities in geology, soils, and plant associations. Repeatable patterns of soil complexes and plant communities are useful in delineating map units. LTAs are an appropriate ecological unit to use in Forest- or area-wide planning and watershed analysis. On the RGNF, soil mapping units were aggregated into 13 distinct LTAs. Long-Butt: A section cut from the bottom log of a tree and culled because of rot or other defect. Natural Regeneration: The establishment of a plant or a plant age class from natural seeding, sprouting, suckering, or layering. Non-system Road: Also termed “Unclassified Roads.” Roads on National Forest System lands that are not managed as part of the forest transportation system, such as unplanned roads, abandoned travelways, and off-road vehicle tracks that have not been designated and managed as a trail; and those roads that were once under permit or other authorization and were not decommissioned upon the termination of the authorization (36 CFR 212.1). Noxious Weeds: A plant specified by law as being especially undesirable, troublesome, and difficult to control. Reforestation: The re-establishment of forest cover, either naturally or artificially. This process usually maintains the same forest type and is done promptly after the previous stand or forest was removed. Road Maintenance: The ongoing upkeep of a road necessary to retain or restore the road to the approved road management objective (FSM 7712.3). Road Construction (New): Activity that results in the addition of forest classified or temporary road miles (36 CFR 212.1). Road Reconstruction: Activity that results in improvement or realignment of an existing classified road as defined below: -Road Improvement - Activity that results in an increase of an existing road’s traffic service level, expands its capacity, or changes its original design function. -Road Realignment - Activity that results in a new location of an existing road, or portions of an existing road, and treatment of the old roadway (36 CFR 212.1). Road Spot Reconstruction: Road reconstruction activities on very short sections of road. Generally involve activities such as culvert replacement and surface rock replacement.

Final Environmental Impact Statement Rio de los Pinos Vegetation Management Project Sanitation/Salvage: The removal of trees that are a) under attack or potentially under attack of insects or disease, or b) recently dead—for the purpose of minimizing current or future loss of wood products. Scenic Integrity Objectives: measures how much human alteration can deviate from the existing landscape character being viewed. The following is a list of the Scenic Integrity Objectives: -Very High Preservation – refers to landscapes where the valued landscape character is intact with only minute if any deviations. -High Retention – refers to landscapes where the valued landscape character appears intact. Deviations may be present but must repeat the form, line, color, texture, and pattern common to the landscape character so completely and at such scale that they are not evident. -Moderate Partial Retention – refers to landscapes where the valued landscape character appears slightly altered. Noticeable deviations must remain visually subordinate to the landscape character being viewed. -Low Modification – refers to landscapes where the valued landscape character appears moderately altered but they borrow valued attributes such as size, shape, edge effect, and pattern of natural openings, vegetative type changes or architectural styles in the surrounding landscape. -Very Low/Maximum Modification – refers to landscapes where the valued landscape character appears heavily altered but may not borrow from valued attributes such as size, shape, edge effect, and pattern of natural openings, vegetative type changes, or architectural styles within or outside the surrounding landscape. Structure Class: A classification of forested cover types which aggregates Habitat Structural Stage into broader categories. Silvicultural system: A planned series of treatments for tending, harvesting, and re-establishing a stand. The system name is based on the number of age classes (i.e. even-aged, two-aged, uneven-aged) or regeneration method (i.e. clear-cutting, seed tree, shelterwood) used. System Roads: Also termed “Classified Roads.” Roads wholly or partially within or adjacent to National Forest System lands that are determined to be needed for long-term motor vehicle access, including State roads, county roads, privately owned roads, National Forest System roads, and other roads authorized by the Forest Service (36 CFR 212.1). Temporary Road: A road needed to access timber for the current project but not needed for long term resource management. Trap Tree: A log or tree felled or treated in a manner to invite insect infestation, particularly bark beetles.
