Hasanuddin University (UNHAS) works directly to maintain and restore threatened ecosystems in South Sulawesi. In 2025, this work included planting trees along eroding riverbanks and coastlines and on campus, and surveying endangered wildlife.

On 24 May 2025, the Department of Soil Science, Faculty of Agriculture, held a community service activity, “Tree Planting for Riparian Conservation to Support the Restoration of River Border Areas”, in Tompobulu Village. Working with the sub-district leadership, village extension officers, students, and residents, with about 150 participants in total, the team planted trees along the riverbanks to reduce erosion, improve water quality, and restore biodiversity along the river.

On the same day, 24 May 2025, the “Protecting Our Coasts: Tree Planting for Climate Resilience” activity planted trees at Pantai Indah Bosowa to form a natural barrier against coastal abrasion, sequester carbon, and strengthen the coastal vegetation that buffers the shoreline and supports marine life.

On campus, students are introduced to this work at the start of their studies. During the orientation for new students of the Faculty of Mathematics and Natural Sciences, held on 12–14 August 2025, all new students, together with the Dean and the Faculty’s leadership, planted tree seedlings as part of a sustainability-themed orientation supported by the UNHAS SDGs Center.

UNHAS also turns research into the direct protection of threatened species. In early 2025, a UNHAS research team carried out in situ monitoring and tracking of endangered large mammals in the Faruhumpenai Nature Reserve, East Luwu, a reserve that has suffered illegal forest destruction, to identify critical wildlife habitat and guide its protection. Such field surveys help maintain the biodiversity of threatened terrestrial ecosystems.
