Degraded forest in Lahnberge, Germany: the soil is being washed out due to lack of vegetal cover, some trees are losing ground and they appear to be sick (photo by Andreas Trepte). Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does ...
The first tree was an Austrian pine planted on the H.E. Curtis farm near Willow, Oklahoma, on March 18. [3] The project called for large-scale planting of trees across the Great Plains, stretching in a 100-mile wide zone from Canada to northern Texas, to protect the land from wind erosion.
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
[35] [36] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [37] [38] [39] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
Pine savanna (pine land) extended to the Atlantic plain (1779 map). The oak-hickory forest of the Northeast was primarily burned by Native Americans, resulting in oak openings, barrens, and prairies in the Northeast and the Piedmont of North Carolina. There was nearly annual burning throughout the Northeast. [7]
As the planet faces more intense and severe effects of climate changes, each element of the eastern temperate region will be affected, from flora and fauna, to soil and water. Vegetation mortality, soil content, species existence, water levels, and overall functionality of the Eco region will continue to change and be altered as global warming ...
There are dozens of erosion prediction models.Some models focus on long-term (natural or geological) erosion, as a component of landscape evolution.However, many erosion models were developed to quantify the effects of accelerated soil erosion i.e. soil erosion as influenced by human activity.
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
