dc.description.abstract | The wetland ecosystem is located at the interface of the atmospheric, terrestrial
and water system. It is one of the most biologically diverse ecological landscapes on
earth and one of the most important environments for mankind. It also called
“kidney” of the landscape because it can purify water that passed through the
wetland. Forested wetland is one of the classifications of wetland, also defined as
swamp, dominated by trees and plays a significant role in timber supply for forestry
business. Forest harvesting such as clear-cut, is the most common silvicultural
method used in forest regeneration. However, it can alter the functions of the
forested wetland ecosystems –biogeochemical cycling. Data have been collected
from several literature reviews and explores how forest harvesting impacts carbon,
phosphorus, nitrogen, calcium and potassium cycles. After data analysis, the five
nutrients were reduced after forest harvesting, but the changes in nitrogen content
were considered minimal. Harvesting has a direct impact on biogeochemical cycles
and it is important to protect the wetlands by maintaining the levels of nutrients and
quality of environment and ecosystem. | en_US |
