Causes[ edit ] The earliest published notion of bush encroachment dates back to A general distinction can be made between bush encroachment due to land intensification and bush encroachment after land abandonment. Literature further suggests that the causes of woody encroachment differ significantly between wet and dry savanna. This is for example the case in former forest areas in the Alps that have been converted to agricultural land and later abandoned. In Southern Europe encroachment is thus linked to rural exodus. According to the two-layer theory, grasses use topsoil moisture, while woody plants predominantly use subsoil moisture. If grasses are reduced by overgrazing, this reduces their water intake and allows more water to penetrate into the subsoil for the use by woody plants. Population pressure can be the cause for bush encroachment, when large trees are cut as building material or fuel. This stimulates coppice growth and results in shrubbiness of the vegetation. Already one decade of land management change, such as the exclusion of fires and overgrazing, can lead to severe bush encroachment.Share: Effects Of Overgrazing On Soil
| ELEVEN BY DALTON TRUMBO ANALYSIS | 4 hours ago · Soil organic carbon (SOC) fractions play a crucial role in the carbon cycle of alpine wetland ecosystems and regional climate regulation. In the last decades, alpine marshes at Tibetan Plateau have undergone increased degradation. The effects of marsh degradation on soil labile and recalcitrant organic carbon fractions and on SOC stability remain unclear. 21 hours ago · effect of soil quality on agriculture - soil quality is determined by depth, texture, mineral content and water capacity. frequently stripping the topsoil and its nutrients and structure. erosion is inevitable especially after overgrazing, over cultivation, poor land management and over population. Jul 10, · Bush encroachment (also shrub encroachment, woody encroachment, bush thickening) is a natural phenomenon characterised by the increase in density of woody plants, bushes and shrubs, at the expense of the herbaceous layer, grasses and forbs. It predominantly occurs in grasslands, savannas and woodlands. The term bush encroachment can refer both to the expansion of native plants as well . |

Changes caused by overgrazing
Forest Regulations These are laws promulgated by government in the form of edicts, decrees and bye-laws to prevent from exploiting or indiscriminate tapping of forest resources. These regulations, therefore, ensure the preservation of forest resources Forest regulations in Nigeria include: The link of bush burning Ban on indiscriminate cutting Efcects timber trees Encouraging people to plant tress Ban on Effects Of Overgrazing On Soil of leaves and firewood from the trees People are to obtain license so as to secure the permission to enable them to cut down trees for human needs.
The felling quantity should be based on the number of forest stands which must be determined before felling. Selective Exploration Selective exploration is the process of cutting or harvesting only mature trees in a forest.
Liming and Fertilizing
It is a way of concentrating certain selected species of timber in a forest reserve. The system allows for the harvesting or older trees while the younger ones remain Effects Of Overgrazing On Soil cover to the surface of the forest. Advantages of Selective Exploration It ensures the concentration of selected species of timber in a forest It protects the soil from erosion It ensures the continous supply of timber It serve as a revenue base click the government It prevent indiscriminate felling of timber by giving license to saw millers by state forestry division It also prevents illegal felling of trees and farming by using forest guards to police the forest.
Undesirable species of timber are eliminated by this method.
Deforestation Deforestation Effects Of Overgrazing On Soil the continuous removal of forest stands trees either by bush burning or indiscriminate felling without replacing them. Economics trees such as Iroko, Obeche, Mahogamy, etc are cut down so that they can be used for various purposes such as furniture like tables, chairs, doors, etc. The rate of deforestation should be reduced to the barest minimum because of its adverse effects. Causes of Deforestation Deforestation can be caused for many reasons which include: Unfavourable Climate Factors: Persistent and prolonged drought can lead to death of forest species.
Also, the exploitation of timber for furniture, export, etc. Also, petroleum exploration and sitting of industries involved clearing of forest Natural disasters: fire is the most serious problem to which forests are exposed, especially during the dry season. Bush burning is caused by fire used by farmers. Such fire may extend to the forest, thereby destroying tree species. Other natural disaster which can cause deforestation include landslide, earthquakes, volcanic eruptions and prolonged flooding.

Government Policies: Government inadvertently introduces policies that can encourage felling of fuel woods and timber exploitation. Effects or Disadvantages of Deforestation Deforestation has come effects or disadvantages on the environment.
These are: Deforestation encourages or increases soil erosion It leads to loss or organic matter, resulting in the loss of soil fertility It reduces the amount of rainfall in the area, or, it causes the destruction of watershed. It decreases soil moisture retention It increases the leaching of plant nutrients Deforestation destroys the micro-climate, and warms up the environment. It also reduces the forest fauna wild life population in the area concerned.]
