Forest management activities within the riparian zone have the potential to change the distribution, size, and abundance of large woody debris in streams (12, 36, 42) and to simplify stream channels (35). Streams are severely depleted in large woody debris due to splash-damming, stream cleaning, and harvest of trees in the riparian zone (14, Invasive Exotic Plant Species in Sierra Nevada Ecosystems1 Carla M. D’Antonio,2 Eric L. Berlow, 3 and Karen L. Haubensak4 Introduction The Sierra Nevada is a topographically and floristically diverse region of the western United States.

The Sierra Nevada is the primary source of water for much of central and southern California, supporting both agriculture and municipal Size: 9MB. The large woody debris changes bed and bank morphology and increases channel complexity (Ralph et al. ). Pool formation in forested ecosystems is controlled in part by the size and abundance of large woody debris, but other factors are also important (e.g., sediment supply; Buffington et al. ).Cited by:
The lowest-elevation biotic zone in the Sierra Nevada is found along the boundary with the Central Valley. This zone, stretching in elevation from to 3, feet ( to 1, m), is the foothill woodland zone, an area that is hot and dry in the summer with very little or no snow in the winter. The foothills are vegetated with grasslands of mostly non-native grasses, mixed grasslands and Biome: Temperate coniferous forests. Sierra Nevada ecosystem services. The forests of the Sierra Nevada deliver important benefits to the citizens of California and the rest of the world. With the extensive exploitation that began with the gold rush, the Sierra Nevada has provided considerable timber, feed for grazing animals, and irrigation water for local agriculture.

In andpiece movement was quantified and new debris pieces. Large woody debris (LWD) is a key link between riparian forests and streams; however, the temporal dynamics of in-stream wood remains poorly quantified. Using dendrochronology, we evaluated the dynamics of five Pinus -dominated and five Picea -dominated riparian forests in the foothills of Alberta and cross-dated the ring widths of pieces of by: Large woody debris (LWD) was added to eight streams in the central Appalachians of West Virginia to determine if stream habitat could be enhanced and brook trout (Salvelinus fontinalis) populations increased.
Brook trout populations were assessed one year prior to habitat manipulation and 3 years post-habitat by: The assumption that a lack of large woody debris is limiting stream habitat and brook trout populations was not supported by our results.
In high-gradient streams, habitat complexity may be governed more by the abundance of boulders and large woody debris may have a lesser influence on trout by: 4.
Large woody debris present in streams at the time of harvest was significantly larger than debris recruited as a result of buffer windthrow (t-test; p. Introduction. Woody debris in upland and riparian forests, including large woody debris (LWD) defined as downed logs that intersect the bankfull margins of a stream, has been linked to many important ecological functions (Harmon et al., ).For example, LWD provides stream channels with structural complexity and stability (Montgomery et al.,Rot et al., ) by contributing to the Cited by: Highlights Woody debris was surveyed in old-growth and clear-felled headwater streams.
Clear-felled streams had significantly more woody debris than old-growth streams. Woody debris in clear-felled streams had an increased functional role.
This episodic input of wood may influence stream functioning for many decades. Foresters should consider a more continuous supply of woody debris by: 8.

High-severity fire in forested landscapes often produces a post-fire condition of high shrub cover and large loads of dead wood.
Given the increasing patch size of high-severity fire and the tendency for these areas to reburn at high severity in subsequent wildfires, post-fire management often targets restoration of these areas. However, these areas are challenging to manage, in part due to Author: Jamie M.
Lydersen, Jamie M. Lydersen, Brandon M. Collins, Michelle Coppoletta, Melissa R. Jaffe, Hud. This research explores large woody debris (LWD) dynamics in five year old lodgepole pine-dominated and five > year old spruce-dominated riparian forests of the Foothills Model Forest in west-central Alberta.
The objectives of my research were (l) quantify the abundance and type of in-stream LWD in mature pine and spruce forests, (2) determine ages of in-stream LWD using tree-ring.

Geomorphology, hyporheic exchange and selection of spawning habitat by bull trout (Salvelinus confluentus). Introduction. The role of in-channel woody debris in many lotic systems is well documented. Debris can help maintain channel stability in forested lands, decrease flow velocity, protect banks from erosion, trap sediment, and provide habitat for in-stream.
We compared the stream habitat characteristics and macroinvertebrate assemblages of boreal headwater streams in both the Finnish and the Russian parts of a single river basin, the Koitajoki River.
Over the last 50 years, the Finnish side of the catchment has been managed using modern forestry techniques, whereas Russian side has remained nearly unexploited and is near to its natural state.
By examining the characteristics of large woody debris in streams bordered by forests of different age classes, the authors document the ways in which large woody debris volume changes following timber removal from the riparian area.
