In the case study of the amboseli national reserve, scientists were trying to determine a cause for the loss of woodland habitat at the foot of mt. kilimanjaro. after years of study, they concluded that the loss of habitat was due to a) the clearing of land by farmers b) the overgrazing of herds by maasai peoples c) the consumption of fever tree bark by elephants d) the complex interaction between rainfall, soil salinity, and other factors

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
