nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation. Besides‚ failure of rains‚ floods‚ depopulation and loss of cattle caused by famine and pestilence‚ disturbance caused by war and interference with or change in the natural

Evaluate the evidence for human impacts on downstream flood risk in rural catchments in temperate regions. Before we can evaluate human impacts on flood risk we must first establish what is meant by temperate regions and also rural catchments. Temperate regions are generally regarded as lying between the Tropic of Cancer and the Arctic Circle or the Tropic of Capricorn and the Antarctic Circle and therefore rivers investigated in this essay will fall within these parameters. Rural catchments are

The climate in this region is cooler summers and warmer winters and a lot of precipitation. The vegetation in the Atlantic Maritime includes deciduous‚ Boreal and Acadian forests which contain a variety of different plant species such as coniferous and deciduous trees and various types of moss. I included the Acadian forest in my poster

rainfall and promotes greater sub-surface transfers via its root system. The presence of vegetation is another factor that would affect the flows within the drainage basin. Vegetation would intercept rainfall‚ decreasing the amount of rainfall reaching the surface. Also‚ it decreases the intensity of raindrops hitting the ground‚ thus it is more likely to infiltrate and percolate into the ground. Vegetation also loosens soil to make larger air space between the soil particles. Thus‚ more infiltration

Also I got learn a lot of new flora and fauna species and its scientific terms that I had in my course of study.

The Giraffe and the Okapi are the only two‚ and Giraffes are the tallest mammals in the world. “Both are tall animals that browse on vegetation; today giraffes occur only in Africa and south of the Sahara‚ although they formerly live in North Africa‚ too.” (Bernabeo‚ 2010) Okapis are not squarely spotted such as the giraffe; instead they have a long brown neck and

Although highly regulated in NSW‚ the clearing of all types of vegetation has placed Australia in the top ten land clearing nations in the world. In the past‚ between the years of 1984 and 1989‚ the Western Lands Commission allowed clearing licenses for over 560‚000 hectares along the NSW Coast‚ particularly the Hastings

Using two contrasting case studies‚ discuss management schemes in fragile environments. A fragile environment is when there the balance between climate‚ soils‚ vegetation‚ animal life and people could easily be upset and the ecosystem destroyed. In order to maintain a fragile environment dynamic sustainability needs to be established. An example of a fragile environment is the Serengeti National Park and Jau National Park. The Serengeti National Park is situated in the Tropical Grassland biome

open burning. In fact‚ brush and debris burning is the second most common preventable cause of wildfires. A lack of green vegetation‚ lots of dead vegetation‚ warm temperatures‚ sun and winds all allow wildfires to start easily and spread quickly. However‚ they could be prevented with safe alternatives like chipping‚ composting or simply waiting for the growth of new green vegetation later in the spring.
