Core Viewpoint - The article emphasizes the ecological significance of the Xishuangbanna rainforest and the impact of rubber tree plantations on the local environment, highlighting the need for restoration efforts to preserve biodiversity and the natural ecosystem [7][11][25]. Summary by Sections Xishuangbanna Rainforest - The Xishuangbanna rainforest is characterized by its rich biodiversity and unique ecological features, which have been affected by extensive rubber tree cultivation since the 1990s [7][11]. - The expansion of rubber plantations has led to ecological degradation, resulting in fragmented habitats and loss of native species [7][25]. Ecological Restoration Efforts - Local communities are beginning to replace poorly performing rubber trees with diverse native species to restore forest biodiversity, a process that may take decades [11][26]. - The restoration of habitats for Asian elephants is a critical focus, as their natural habitats have been disrupted by agricultural expansion [25][26]. Importance of Keystone Species - Keystone species, such as the towering trees in the rainforest, play a crucial role in maintaining the structure and function of the ecosystem, influencing light, water, and nutrient cycles [20][25]. - The article highlights the ecological functions of Asian elephants in shaping the forest structure and promoting biodiversity through their foraging activities [23][24]. Challenges and Future Directions - The restoration of the rainforest ecosystem faces challenges, including the need for long-term funding and policy support to ensure the continuity of restoration efforts [26]. - The article calls for greater awareness of the complexities of the rainforest ecosystem and the importance of sustainable practices in tourism and agriculture [26][27].
