Water quality monitoring in Sugut River and its tributaries

WWF-Malaysia initiated the water quality monitoring using physic-chemical and biological parameters along the lower Sugut River and its tributaries to monitor the status of water quality in the area, especially in areas surrounded by oil palm plantations. A total of 12 sampling stations were selecte...

A total of 12 sampling stations were selected at four tributaries of Sugut River based on agreement with WWF staff members and Sabah Forestry Department (SFD) officer.
