Inner gorge definition

Inner gorge means a geomorphic feature formed by coalescing scars originating from landsliding and erosional processes caused by historically active stream erosion. The feature is identified as that area beginning immediately adjacent to the stream channel below and extending up slope to the first break in the slope.

Inner gorge means a geomorphic feature formed by coalescing scars originating from landsliding and erosional processes caused by historically active stream erosion. The feature is identified as that area beginning immediately adjacent to the stream channel below and extending up slope to the first break in the slope. “Large woody debris (LWD)” means larger pieces of wood in stream channels or on the ground, including logs, root wads, and large chunks of wood that provide important biological and physical functions. “Logging area” see Section 895.1 Definitions, of Title 14 of the California Code of Regulations (14 CCR).

Inner gorge. An inner-gorge is a physiographic feature that can occur along valley side-slopes adjacent to stream channels, and is characterized by steep slopes at the base of the valley that flatten at a distinct break-in-slope with a gain in elevation. It can be considered “a valley within a valley” (after Kelsey 1988). The lower slopes of these features are generally defined by slopes exceeding 50% although in more competent bedrock, inner gorge slope gradients typically exceed 65%. In northern California, inner gorges are best developed in mid-order stream reaches 1988). Chronic mass wasting, such as shallow landsliding or deep-seated transrotational features, is the main erosional hillslope process associated with inner gorges. Low thinning: A low thinning is to be used in conjunction with treatments in Zone A of Class I WLPZs. This thinning involves the removal of the understory, mid-canopy, and very limited numbers of co-dominant trees. Co-dominant trees may be removed only to improve spacing and enhance growth. Dominant trees may not be removed, and average stand diameter must increase following harvest. Overstory trees (for WLPZ only): Trees that occur in the mid to upper canopy and are at least 50’ tall. % Overstory Canopy: Canopy closure provided by the overstory trees as measured against 100%. Permanently designated: Trees are to be marked in such a manner that the designation will be retained for sufficient time to identify upon the next entry following the initial marking. This may include a combination of paint, tree tags, blazes, metal fence posts, etc. Marks will be applied both above and below the xxxxx line. Recruitment trees: Recruitment trees are permanently designated trees within Zone A of Class I WLPZs. These trees shall be the ten largest trees per 100 meters within 50 feet (slope distance) of the watercourse transition line. The RPF may propose, with concurrence from trading for smaller diameter trees that are more conductive to recruitment as LWD. Recruitment

More Definitions of Inner gorge

Inner gorge means canyons created by a combination of the downcutting action of a stream and mass movement on the slope walls; they commonly show evidence of recent movement, such as obvious landslides, vertical tracks of disturbance vegetation, or areas that are concave in contour and/or profile.
