It still resonates in our minds that last 2023 was marked by unusually hot days. According to several studies, it was recorded as the hottest year in global temperature since this data was first recorded in 1850. The year was also impacted by El Niño, a natural climate warming phenomenon that can affect global weather. Climate change exacerbated the effects of El Nino in 2023  leading to prolonged droughts and heatwaves, which triggered severe wildfires in various regions, including Indonesia. 

One of the major events linked to the phenomenon was the wildfires that devastated several forests in Indonesia’s mountainous areas, with over 140 incidents recorded throughout the year. Merbabu Mountain in Central Java Province suffered some of the worst damage, with over 480 hectares of forest burned. The fire was allegedly caused by natural leaves friction, although human actions like discarded cigarette butts or burning trash may have also played a role.

A Year After the Wildfire: Youth Community Reforests Fire-Damaged Area 

One year has passed since the devastating wildfire on Merbabu Mountain in October 2023. It destroyed much of the forest cover, including valuable vegetation, such as edelweiss, cantigi, and tree species like puspa, pines, cinnamon, and wilodo. While some parts of the forests have been reforested, other fire-affected areas remain barren. This has motivated the youth community of the Executive Student Board (BEM) Diponegoro University to take action, mobilizing youth communities to restore the land by planting trees.

Collaborating with Trees4Trees, they organized a tree-planting event through an annual environmental program, Gerakan Aksi Tanam Pohon (GESIT) or the Tree Planting Action Movement. The event took place on October 20, 2024 – exactly one year after the wildfires struck. 

“Aligned with our program in conservation, we initiated this tree-planting activity. In total, 70 volunteers from twelve faculties joined as tree-planting volunteers to help the environment, particularly by reforesting fire-affected areas,” said Jania, a student of Diponegoro University and coordinator of the tree-planting activity. 

A Green Collaboration to Recover the Environment 

Together with Trees4Trees, the Gen Z volunteers planted 500 trees along the Thekelan hiking trail on the slope of Merbabu Mountain, in Getasan District, Semarang Regency.  

“This tree-planting aims to support ecosystem recovery, allowing the trees to produce more oxygen to benefit all living beings. This small action reflects our care as young generations for the environment,” said Izza, a Diponegoro University student and leader of the Conservation and Disaster Division. 

As part of its mission in education and sustainability promotion, Trees4Trees provided volunteers with essential training on tree-planting techniques and preparations a week before the event. Danang Pambudi, a Trees4Trees forester who led the training, emphasized the importance of sharing tree-planting knowledge with young people. “We hope this education encourages them not only to plant trees at this event but to continue planting more in the future, wherever they can,” he said. 

Why Is It Important to Plant Trees in the Fire-Affected Area? 

Danang revealed, Trees4Trees supported the tree-planting event by providing three species of trees: puspa, cinnamon, and wilodo, all of which are characteristic of Merbabu Mountain. Some of them were diminished during the wildfire. 

“We selected the trees to fit the existing ecosystem. Merbabu is the natural habitat for these species, and by planting them, we help restore the ecosystem. In fact, the puspa tree is even fire-resistant,” said Danang. He also emphasized that if fire-affected areas are left neglected, they will eventually recover on their own. Birds and wind will disperse the seeds of native trees naturally, encouraging regrowth, but it takes time. “By planting these characteristic trees in their natural habitat, we help to accelerate ecosystem recovery. Additionally, we also help enhance carbon sequestration, contributing to fight climate change,” he explained. 

Empowering Youth through Trees4Trees Youth4Change 

Trees4Trees‘ involvement in this collaborative tree-planting event was backed with the aim to raise awareness about environmental preservation among the young generation. This initiative is part of the Trees4Trees Youth4Change program, designed to empower youth to express their concerns and take action for a greener planet. 

Hatta Iskandar, the Trees4Trees Fundraising Manager, noted that Youth4Change offers opportunities for youth to engage in impactful actions for environmental preservation. “We are excited to collaborate with young communities, especially in tree-planting activities. We hope to continue this collaboration in the future and involve more youth in the green movement,” he stated. 

In the other hand, Danang emphasized the younger generation holds the key to a sustainable future. “It’s vital to cultivate a sense of environmental responsibility in young people. By supporting positive initiatives and sharing knowledge, we can inspire a deep commitment to protecting our planet,” he said.
