methane and nitrous oxide fluxes from a fire chronosequence in subarctic boreal forests of canada. Science of the Total Environment, 601, 895-905. doi:10.1016/j.scitotenv.2017.05.246 In the article “Carbon dioxide, methane and nitrous oxide fluxes from a fire chronosequence in subarctic boreal forests of canada,” the authors studied the effects of forest fires in Northwestern Canada. Koster et al. focused on the effects that forest fires had over time, on three greenhouse gases. There were three main

coastal rainforest, subalpine, and alpine. Each habitat is diverse, unique, and relates to its neighboring community. The diversity of plant and animal species in the Upper Lynn Canal remain among the highest in Alaska. Subarctic alpine, boreal forest, north coast forest, and marine systems converge at KLGO and the park hosts species assemblages found nowhere else in the world. Vegetation distribution is governed by a number of factors including soil type, depth, drainage, light availability, precipitation

Myra T.  2/26/17 ESSAY Earth & space science Semester 2: Taiga Region  Introduction            The boreal forest, also known as the Taiga region is the major life zone of vegetation that is composed of various trees, soils, flora, and fauna. The Taiga region reaches across the upper northern hemisphere. Thus following across Canada, Alaska, and northern New England: making this the largest land biome in the world. In this particular region, there are various types of soil, flora, and fauna that

of our unique forest resource. Ninety percent of the earth’s trees between three and four hundred years old have been cut down. The remaining ten percent is all we will ever have (Gallant, 97). The definition of deforestation by the Random House Dictionary of the English Language is "to divest or clear of forests or trees.” Deforestation is one of the most significant issues of our time; considerable measures must be taken to prevent further pillaging of our unique forest resource.

temperate rainforests of the Pacific Northwest and the dry and mountainous Northern Rockies. According to the Yaak Valley Forest Council, the valley is home to a variety of rare species including but not limited to: inland redband rainbow trout, bull trout, wolverine, lynx, fisher, coeur d 'alene salamander, great gray owl, westslope cutthroat trout, flammulated owl, short-head sculpin, boreal owl, peregrine falcon, wavy moonwort, kidney-leaved violet, bog birch, and Grizzly Bears (About The Yaak, 2015).

are short with strong leaves that hold onto moisture. Animals usually hunt at night to avoid the scorching heat of the day. The animals that live in the chaparral are insects, bird, coyotes, deer and jack rabbits. Temperate Deciduous Forest Temperate deciduous forests are made up of deciduous trees, meaning they lose their leaves every year in winter and grow them back in spring. Summer temperatures are around 20 degrees while winter temperatures can reach well below freezing. The annual rainfall

Now with new technology, such as satellites systems, low altitude photography and side looking radar, scientists can now figure that the world is losing about 20.4 million hectares of tropical forests annually and if these figures are not reduced, we will lose all of our tropical forests in about 50 years. It has been suggested that the high deforestation rates are caused partly by the fact that the new surveys are more accurate and thus reveal old deforestation rates that have not been

for this decline, resulting in serious impacts on the environment and the economy. Critically discuss the causes of deforestation and solutions to it. Deforestation is the cutting down of a large area of trees and the destruction of forests by people. Forests are what we call an exhaustible resource, one which can be used up if it is not used carefully. Over the last few decades, deforestation has threatened the rainforests with total extinction. To understand why deforestation is such an important
