    One of the side effects of technology advances is the inability of nature to decompose substances humans create. For example, polythene used in shopping bags is non-biodegradable -- it doesn't beak down naturally in landfills. Non-biodegradable waste can last for centuries and cause environmental problems that affect more than just the land. [image_assist|fid,style:left,nid]The environmental consequences of large dams are numerous and varied, and includes direct impacts to the biological, chemical and physical properties of rivers and riparian (or "stream-side") environments.

    Ecological Applications is concerned broadly with the applications of ecological science to environmental publishes papers that develop scientific principles to support environmental decision-making, as well as papers that discuss the application of ecological concepts to environmental issues, policy, and management. Furthermore, environmental benefits are often difficult to quantify and may not receive as much consideration as those which are easily quantifiable. This section attempts to identify and describe these key environmental effects, as well as the potential drawbacks or challenges of preserving parks and open lands region-wide.

    Anadromous Pacific salmon (Oncorhynchus spp.) transport marine-derived nitrogen (MDN) to the rivers in which they reproduce. Isotopic analyses indicate that trees and shrubs near spawning streams derive % of their foliar nitrogen (N) from spawning salmon. As a consequence of this nutrient subsidy, growth rates are significantly in­creased in Sitka spruce (Picea sitchensis) near. Certain agricultural land use practices, such as overgrazing, land conversion, fertilization, and the use of agricultural chemicals, can enhance the growth of invasive plants. 5 These plants can alter fish and wildlife habitat, contribute to decreases in biodiversity, and create health risks to livestock and humans.

Ecological effects on streams from forest fertilization--literature review and conceptual framework for future study in the Western Cascades / By Chauncey W. Recent adoption of numeric nutrient criteria (NNC) for streams and lakes in Florida has raised concerns that forest fertilization, even in compliance with BMPs, may result in excess nutrient loads and degrade stream ecological condition, particularly directly following fertilizer applications.

In the research project ARINUS, the effects of restabilization measures (fertilization with readily soluble MgSO4) on the element cycling of Norway spruce ecosystems in the Black Forest (SW Germany) are studied. The objective is to quantify the natural and anthropogenic components of element cycling.

Interrelations between the terrestrial and aquatic subsystem are assessed using an integrated. Watershed effects were compared with results from a study on the same small watersheds inin which two combinations of harvesting and mechanical site preparation without BMPs or fertilization.

In level contrives where the general effect of an forest is to drain the soil and lower the ground water, springs seldom cover and the effect of the forest upon them is of minor importance.

Influence on Floods. Forests, in reducing surface runoff and increasing seepage, extend the time over which precipitation reaches as streams. The growth enhancing effects of forest fertilizer is considered to level off within 10 years of the application, and be restricted to one forest stand rotation.

However, fertilizer induced changes in plant community composition has been shown to occur in the following stand rotation. To clarify whether effects of forest fertilization have residual long-term effects, extending into the next.

Groundwater controls on colloidal transport in forest stream waters. regulated by fertilization, forest ecosystems synthesis of the ecological effects of clear-cutting as a basis for more. Our first casestudy was sited around the remnant riparian forest in the lower Fraser River (), where we considered the possibility of fertilization effects from pink and sockeye salmon spawn in odd numbered years and in a single season there can be >10 million spawning fish in the lower Fraser region, though exact counts are difficult (Grant et al., ).

As per Wikipedia, “Eutrophication or more precisely hypertrophication, is the ecosystem’s response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic example is the “bloom” or great increase of phytoplankton in a water body as a response to increased levels of nutrients.

Tools. Modeling the effect of fire on aquatic systems. These models predict the potential of fire to alter critical in-stream salmon habitat by modeling a fire’s potential to facilitate delivery of fine sediments and large wood to stream channels.

They are based on the geomorphology of stream channels combined with complex models of fire behavior and fire intensity across the landscape. Get this from a library. Effects of forest fertilization with urea on stream water quality, Quilcene Ranger District, Washington.

Forest fires prediction combines weather factors, terrain, dryness of flammable items, types of flammable items, and ignition sources to analyze and predict the combustion risks of flammable items in the forest.

Forest fire prediction has developed rapidly in various countries in. The effects of forest habitat loss during urbanization may be especially severe for forest-dwelling salamanders.

A previous investigation 4 of the same forest indicates that increased CO 2 levels do not have much of an effect on the leaf-area index (LAI, a measure of total canopy leaf area) in this location. Although plant community responses to increased N availability in coniferous forests, as those described above, are fairly well known, and in accordance with predictions from general ecological models of plant competition (Tilman, ), the biological effects from commercial forest fertilization other than increased tree productivity, have.Fertilization in Sweden and Finland is currently practiced by extensive fertilization regimens where nitrogen fertilizers are applied once, or up to three times, during a rotation period, mainly in mature forest.

This type of fertilization gives, in most cases, a small and transient effect on the environment as well as a high rate of return to.
