This area is also a habitat for rare animals such as elephants, rhinos, tigers, and Sumatran orangutans. Damage to Kappi will worsen the Tamiang River Basin (DAS), most of which originates in this area, and threaten the survival of wildlife. However, plans to change the status of Kappi from the Core Zone to the Utilization Zone for the construction of a geothermal power plant have been rejected by various parties because it will damage this natural ecosystem. Experts emphasize the importance of maintaining Kappi as one of the last intact flat forests in Sumatra. Destroying Kappi not only threatens environmental sustainability but also the lives of the people who depend on this ecosystem.[2][3][4]
