Background: This research explores the improvement of biology learning outcomes through the integration of local natural resources conservation and the promotion of environmental literacy among students at SMA Negeri 1 Baregbeg, Ciamis, and SMA Negeri 1 Karangnunggal, Tasikmalaya. Aim: The study focuses on developing effective learning management strategies that encourage student engagement and enhance their environmental literacy. Material and Methods: A qualitative case study approach was adopted, involving interviews, observations, and documentation to collect data on the implementation of biology learning based on local conservation efforts. Results: The research examines how schools can collaborate with various stakeholders, including government agencies and community organizations, to integrate conservation knowledge into the curriculum. Findings highlight the importance of a collaborative approach to education that involves external environmental partners to enrich students’ learning experiences. The study also identifies challenges in infrastructure, teaching methods, and the need for a more structured curriculum that incorporates environmental issues holistically. Through this research, it is emphasized that fostering environmental literacy in biology learning can help students develop critical thinking skills and a deeper understanding of local natural resource management. Conclusion: The results suggest that project-based learning, field studies, and real world applications are key components in cultivating a sense of responsibility for the environment. Recommendations for improving the curriculum include integrating conservation topics into biology education, enhancing teacher training, and fostering partnerships with local environmental stakeholders. This research contributes to the development of a sustainable and contextually relevant educational model that prepares students to address environmental challenges through informed decision-making and proactive engagement in conservation efforts.
