The Tonkin snub-nosed monkey, a species once thought to be extinct, has experienced a remarkable resurgence in one forest, while facing a dire decline in another. This story highlights the complex interplay between conservation efforts and the challenges posed by human activities, particularly cardamom farming, which threatens the delicate balance of these ecosystems.
In the Khau Ca forest, a conservation success story unfolds. The population of these critically endangered monkeys has more than tripled since 2002, with an estimated 80% of the entire species now residing in the reserve. This achievement is largely attributed to the dedicated work of Fauna & Flora International and their partners, who have implemented a multi-faceted approach to conservation.
The survey methodology employed in Khau Ca is a testament to the power of innovation in conservation. By dividing the reserve into sections and assigning each group a specific "cell," the teams ensured efficient and comprehensive coverage of the 1,000-hectare area. The use of thermal imaging drones, camera traps, and audiomoths further enhanced the accuracy and effectiveness of the survey, allowing for the detection of the monkeys' unique calls.
Canh Xuan Chu, the project manager, emphasizes the importance of individual identification in the survey process. The monkeys' distinct coloring, tail patterns, and unique calls make them easy to spot, even in the dense foliage. This attention to detail is crucial for understanding the population dynamics and ensuring the long-term survival of the species.
In stark contrast, the story of the Quan Ba forest paints a different picture. Patrollers in this area have not seen the Tonkin snub-nosed monkeys since 2020, and the recent survey found no signs of the species. The primary culprit behind this decline is cardamom farming, a lucrative but environmentally destructive practice. The clearing of trees for cultivation and the use of firewood for drying fruits degrade the forest ecosystem, making it inhospitable for the monkeys.
The challenges in Quan Ba are exacerbated by the lack of formal protection status for the area. Unlike Khau Ca, where conservation efforts have been more robust, Quan Ba's status as an unprotected area limits the ability of organizations to implement long-term habitat management and protective restrictions. Despite these obstacles, Fauna & Flora continues to maintain a patrol group in Quan Ba, hoping to prevent the complete disappearance of the species.
The organization's efforts to create wildlife corridors from Khau Ca to Quan Ba offer a glimmer of hope for the future. By connecting these two forest areas, Fauna & Flora aims to enhance biodiversity and provide a more secure habitat for the Tonkin snub-nosed monkeys. However, Chu acknowledges the need for increased protection measures and reduced human presence in the forest to ensure the success of this initiative.
In conclusion, the story of the Tonkin snub-nosed monkey serves as a powerful reminder of the delicate balance between conservation efforts and human activities. While the success in Khau Ca provides a model for restoring populations in other forests, the decline in Quan Ba underscores the ongoing challenges in preserving these endangered species. It is imperative that we continue to support and expand conservation initiatives, while also addressing the underlying issues that threaten the health and survival of these precious ecosystems.
