Management Of Pacific Northwest Riparian Forests
Management of Pacific Northwest riparian forests is necessary because many of these forests have been dramatically changed from their original makeup. The primary interest in riparian forest and aquatic ecosystems under the Northwest Forest Plan (NWFP) is the need to restore stream habitat for fish populations, particularly Fish migration, anadromous Salmonidae, salmonids. Some of these forests have been grazed by cattle or other livestock. The heavy hooves of these animals compact the soil. This compaction does not allow the water to be absorbed into the ground, so the water runs off into the stream carrying topsoil along the way. The simplification of the stream itself has also had negative effects. The large woody debris in the streams has been removed to allow for easy access to the stream and for better travel in the streams themselves. But the faster moving current erodes the stream banks, filling the stream with more sediment. The removal of trees on the stream banks ...

Riparian Forest
A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, Sink (geography), sink, or reservoir. Due to the broad nature of the definition, riparian woodlands have a huge diversity of characteristics including but not limited to soil composition, microclimates, and vegetative structures. However, among the varied range and landscapes, one factor stays constant: a high rate of Primary production, primary productivity. This makes riparian forests hugely important centers of nutrient recycling. Etymology The term riparian comes from the Latin word ''ripa'', 'river bank'; technically it refers only to areas adjacent to flowing bodies of water such as rivers, streams, Swamp, sloughs and estuaries. However, the terms ''riparian forest'' and ''riparian zone'' have come to include areas adjacent to non-flowing bodies of water such as ponds, lakes, playas and reservoirs. Charac ...

Slash (logging)
In forestry, slash, or slashings are coarse and fine woody debris generated during logging operations or through wind, snow or other natural forest disturbances. Slash generated during logging operations may increase fire hazard, and some North American states have passed laws requiring the treatment of logging slash. Logging slash can be chipped and used (for example) in the production of electricity or heat in cogeneration power-plants, or simply burned onsite. Where logging takes place on soft ground, loggers can use the branches and tops of trees as part of the timber-harvesting process to provide a track for forest machines. Using slash in this manner reduces ground damage. See also * Coarse woody debris * Lignocellulosic biomass Lignocellulose refers to plant dry matter (biomass), so called lignocellulosic biomass. It is the most abundantly available raw material on the Earth for the production of biofuels. It is composed of two kinds of carbohydrate polymers, cel ...

Flora Of The Northwestern United States
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Forestry In Canada
The Canada, Canadian forestry industry is a major contributor to the Canadian economy. With 39% of Canada's land acreage Forests of Canada, covered by forests, the country contains 9% of the world's forested land. The forests are made up primarily of spruce, Populus, poplar and pine. The Canadian forestry industry is composed of three main sectors: solid wood manufacturing, Pulp and paper industry, pulp and paper and logging. Forests, as well as forestry are managed by Natural Resources Canada, The Department of Natural Resources Canada and the Canadian Forest Service, in cooperation with several organizations which represent government groups, officials, policy experts, and numerous other Project stakeholder, stakeholders. Extensive deforestation by European settlers during the 18th and 19th centuries has been halted by more modern policies. Today, less than 1% of Canada's forests are affected by logging each year. Canada is the 2nd largest exporter of wood products, and produces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fir And Spruce Forests
Firs are evergreen coniferous trees belonging to the genus ''Abies'' () in the family Pinaceae. There are approximately 48–65 extant species, found on mountains throughout much of North and Central America, Eurasia, and North Africa. The genus is most closely related to '' Keteleeria'', a small genus confined to eastern Asia. The genus name is derived from the Latin "to rise" in reference to the height of its species. The common English name originates with the Old Norse ''fyri'' or the Old Danish ''fyr''. They are large trees, reaching heights of tall with trunk diameters of when mature. Firs can be distinguished from other members of the pine family by the way in which their needle-like leaves are attached singly to the branches with a base resembling a suction cup, and by their cones, which, like those of cedars, stand upright on the branches like candles and disintegrate at maturity. Identification of the different species is based on the size and arrangement o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riparian-zone Restoration
Riparian-zone restoration is the ecological restoration of riparian-zone habitats of streams, rivers, springs, lakes, floodplains, and other hydrologic ecologies. A riparian zone or riparian area is the interface between land and a river or stream. ''Riparian'' is also the proper nomenclature for one of the fifteen terrestrial biomes of the earth; the habitats of plant and animal communities along the margins and river banks are called riparian vegetation, characterized by aquatic plants and animals that favor them. Riparian zones are significant in ecology, environmental management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grassland, woodland, wetland or sub-surface features such as water tables. In some regions the terms ''riparian woodland'', ''riparian forest'', ''riparian buffer zone,'' or ''riparian strip'' are used to characterize a riparian zon ...

Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin ''wiktionary:ripa, ripa'', meaning "bank (geography), river bank". Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by aquatic plant, hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on terrestrial animal, terrestrial and semiaquatic fauna as well as aquatic ecosystems, including grasslands, woodlands, wetlands, and even non-vegetative areas.

Douglas-fir
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is the tallest tree in the Pinaceae family. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus '' Abies''), spruce (genus '' Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-sized to extremely large evergreen trees, tall (although only coast Douglas-firs reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal Area
Basal area is the cross-sectional area of trees at breast height (1.3m or 4.5 ft above ground). It is a common way to describe stand density. In forest management, basal area usually refers to merchantable timber and is given on a per hectare or per acre basis. If one cut down all the merchantable trees on an acre at off the ground and measured the square inches on the top of each stump (πr*r), added them all together and divided by square feet (144 sq inches per square foot), that would be the basal area on that acre. In forest ecology, basal area is used as a relatively easily-measured surrogate of total forest biomass and structural complexity, and change in basal area over time is an important indicator of forest recovery during succession . Estimation from diameter at breast height The basal area (BA) of a tree can be estimated from its diameter at breast height Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bol ...
