Large-scale wildfires (∼10 4 –10 6 ha) have the potential to eliminate seed sources over broad areas and thus may lead to qualitatively different regeneration dynamics than in small burns; however, regeneration after such events has received little study in temperate forests. Following a ha mixed-severity wildfire in Oregon, USA, we quantified (1) conifer and broadleaf regeneration. In the late successional phase (after years), trees attained sizes of up to cm dbh. Also field data and simulation output show a good accordance in the late successional phase (Fig. 3c). The gross primary production (GPP) reached a stable level of approximately ± Mg C/(ha y) after approximately years (Fig. 4a).

Taylor AH, Skinner CN () Fire history and landscape dynamics in a late successional reserve, Klamath Mountains, California. Forest Ecology and Management – a late-seral closed to open state occurs about every years. Snow breakage occurs in the mid-seral closed state (class B) about every 5 years. While model is aspatial, most medium and high severity fire may actually occur on mid and upper slope positions (Taylor and Skinner , Taylor , Beaty and Taylor ). Reviewers 2 anonymous.

South Cascades late successional reserve assessment. v Abstract "April "Shipping list no.: es bibliographical references.[v. without special title] -- [v. 2] of access: InternetAuthor: U.S. Fish and Wildlife Service. The habitat within the South Cascades LSRs serves as source areas for spotted owls and other late-successional and old growth dependent species.
LSR is the largest contiguous Reserve within the range of the northern spotted owl. Since species depend on habitat, a. Analysis (WA) was completed in and the South Cascades Late-Successional Reserve Assessment (LSRA) was completed in These documents emphasized the need to restore watershed functions, protect remaining mature and old-growth stands from catastrophic loss, accelerate development of late-successional habitats, reduce.

Lehmkuhl1 This paper documents methods for assessing the potential effects of variable-intensity management in late-successional reserves (LSRs) and provides an example (the Gotchen LSR) from the Cascade Range in eastern.
Ecological and Financial Assessment of Late Successional Reserve Management. egetation patterns in the Gotchen Late-Successional Reserve ( aerial photos; ). Fagergren of remaining old-growth forests. The reserve network was embedded in a matrix of “working” forests and was designed to maintain late-successional (mature or old-growth) forests in a well-distributed pattern across federal lands, to protect stream habitats, and to connect old-growth forests with corridors containing old-forest elements, while.
Assessment Number OR ) for a proposal to implement two projects as follows. Project 1: conduct density management on approximately acres of 45 to 55 year-old stands in Late-Successional Reserve (LSR) and Riparian Reserve (RR) Land Use Allocations (LUA s) within the North Coast Adaptive Management Area to increase structural diversity.
LATE-SUCCESSIONAL RESERVE ASSESSMENT Oregon Coast Province - Southern Portion (RO, RO) There are several additional LSR designations to the south (RO, RO, RO, RO) and to the north (RO, LO, RO) (Map 1) of this assessment area which tie to.
J.W. Dalling, in Encyclopedia of Ecology, Pioneers in Secondary Succession. Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site.
Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession. The assessment identifies management activities needed to: (1) reduce the risk of habitat loss from catastrophic disturbances such as fire, insects, and disease, and (2) sustain late-successional habitats whether the goal is to provide fire or climatic late-successional conditions.
This paper documents methods for assessing the potential effects of variable-intensity management in late-successional reserves (LSRs) and provides an example (the Gotchen LSR) from the Cascade Range in eastern Washington.
The Gotchen LSR study investigates changes in forest vegetation associated with silvicultural treatments, and how different treatment combinations may. the South Cascades Late Successional Reserve Assessment, and the Jackson Creek Watershed Analysis.
Historic aerial photos (,and ) were obtained and compared to recent aerial photos () to help define the extent of meadow perimeter lost to conifer encroachment.
The project. The South Cascades Late Successional Reserve Assessment (LSRA, ) also encourages the strategic use of prescribed fire and other silvicultural treatments to protect, enhance and accelerate late successional characteristics within the project area.

All activities are consistent with the South Cascades Late Successional Reserve Assessment (#RO; USDA/USDI, ) and the South Umpqua River/Galesville Late Successional Reserve Assessment (#RO; USDA/USDI, ).
Approximately miles of new temporary road and reconstruction of miles of non-system. In addition, the Dillon LSR Assessment (USDA For. Ser., ) concluded that most of the LSR still met standards and guidelines as functioning late-successional habitat (USDA-USDI, ) after the fire.
