    Big Marsh late successional reserves
    (1997-10) Crescent Ranger District (Or.)
    Assessment addresses three LSRs within the Big Marsh Watershed : Crescent, Lower Big Marsh,and Upper Big Marsh, providing background, key questions and management strategies. Description of current conditions (forest structure, composition, vegetation patterns and fire-caused mortality projection) provide a framework for identification, design and prioritization of treatments. The three LSRs are comprised of seven plant association groups (dry lodgepole pine, wet lodgepole pine, mixed conifer dry, mixed conifer wet, mountain hemlock, riparian, and rock).

    Davis late-successional reserve assessment
    (1995) Crescent Ranger District (Or.)
    Identifies six areas of existing and historic vegetative conditions and the wildlife species that could logically be managed to provide a similar habitat type and function: mixed conifer for northern spotted owl (54%), mixed conifer for bald eagle (8%), mixed conifer/lodgepole with dual connectivity function (3%), mixed conifer/lodgepole/ponderosa for great grey owl and/or bald eagle (6%), lodgepole with/without riparian for black-backed woodpecker and/or riparian habitat (16%), and mountain hemlock for wolverine and black-backed woodpecker (13%). The six areas were then assessed according to the following criteria: the existing habitat function within and outside of the LSR, the effects of past timber harvesting on the desired habitat function, the risk of catastrophic loss of existing old growth due to fire, insects, and disease; existing human uses within the area; and other factors influencing the attainment of the desired late and old structured ecosystems. The immediate need in the LSR was determined to be reducing the risk of catastrophic loss in a portion of the existing late and old-structured stands that are imminently susceptible to insect attack or wildfire.

    Proposed modifications to Davis late successional reserve assessment
    (2003-03-06) Crescent Ranger District (Or.)
    Proposes to modify the LSR guidelines to leave sufficient down wood in untreated blocks strategically located to meet existing guidelines and to allow adequately for treatments, proposed for the purpose of reducing fire hazard, for development of habitat structure, and treating areas that are necessary to obtain long-term objective as stated in Odell Pilot Watershed assessment and the Davis LSR assessment.
