SRI was born out of deep concern over the shrinking of tropical rainforests, rising wildlife extinction rates, climate change, and the widespread use of environmentally damaging farming practices. To address these challenges, Rado founded SRI with a clear mission: to conserve Sumatra’s tropical rainforests and protect endangered wildlife by actively empowering and developing local communities living around crucial biodiversity areas.

​Today, SRI focuses its work on three vital landscapes: the Batang Gadis National Park, the Batangtoru Ecosystem, and the Siondop Angkola Landscape. These areas are essential natural habitats for the Tapanuli orangutan, the Sumatran tiger, and many other endangered species. Over the last ten years, SRI has dedicated a major part of its conservation efforts to agroforestry initiatives and forest protection patrols.

Throughout the past two decades, the institute has earned the trust and financial support of global conservation partners, receiving grants from foundations and organizations in Japan, the United Arab Emirates, the United States, Germany, Hong Kong, and Indonesia. At its core, SRI believes that acting locally as a grassroots player drives global change—creating a lasting, positive impact for the entire planet.

​Rado led SRI as Executive Director from 2007 to 2021. As he moved on to pursue a career in public service until 2025, leadership was passed to the next generation. Since 2021, Dony Saputra has taken the helm as the Executive Director, leading SRI into its next chapter
