which management plan causes the largest disruption/change in the forest ecosystem?
A
shelterwood cut
B
seed cut
C
selective cut
D
clear cut
Explanation: 

Detailed explanation-1: -Destroys forest ecosystems, depriving wildlife of natural habitats and decreasing biodiversity. Still, fauna can return to the area when the forest is renewed. Increases the risks of soil erosion. Trees slow down water currents, preventing rill formation, this is why clear-cutting increases erosion.

Detailed explanation-2: -A clearcut is an area of forestland where most of the standing trees are logged at the same time and a few trees remain post-harvest. Forested buffers are left around streams and lakes, and the area is replanted within two years of harvest.

Detailed explanation-3: -Clearcutting causes erosion, landslides and contamination of our water supply with sediment and the toxic herbicides used in the clearcutting process. Clearcutting also compacts the ground and decreases the soil’s ability to retain water, ultimately reducing our supply of clean water.

Detailed explanation-4: -According to the secretariat of the UNFCCC (United Nations Framework Convention on Climate Change), agriculture is the root cause of 80% of deforestation. Logging accounts for another 14% and the cutting of trees for use as wood fuel account for 5%.
