Deux exemples d'inventaires de la biodiversité méconnue dans le Parc national des Écrins : la réserve intégrale du Lauvitel en coeur de Parc et une commune de l'aire d'adhésion

Depuis la création de la réserve intégrale du Lauvitel en cœur de Parc national, agents et scientifiques inventorient chaque année la faune et la flore et étudient les milieux naturels qui évoluent sans intervention humaine. Un inventaire général de la biodiversité (2019-2021) a permis d’améliorer la connaissance des espèces méconnues mais pourtant essentielles au fonctionnement des écosystèmes. 648 nouvelles espèces, dont 485 insectes et 110 champignons ont été observées. On estime que selon les groupes, 10 à 80 % des espèces présentes dans le vallon restent à découvrir car les évolutions s’observent sur le temps long. Voir le livret Réserve intégrale du Lauvitel.

Dans le cadre de la charte du Parc national, les communes de l’aire d’adhésion peuvent accueillir elles aussi un inventaire des habitats naturels et de la biodiversité de la commune. 61 contributeurs naturalistes et scientifiques ont ainsi exploré Crots (05) sur 3 jours en 2022.

Shorebirds conservation

Reclamation led to a significant reduction in coastal wetlands, resulting in a dramatic decline in waterbirds, highlighting the urgent need to restore habitats. In order to provide an ideal high tide roost site for the most important shorebird staging site in Yellow Sea, we conducted a restoration project in Tiaozini Wetland. A 720 acre seaward fish pond was developed as a demonstration area for the restoration of high tide roost site. The project has successfully created habitats that meets the needs of various migratory waterbirds through a series of scientific measures such as micro terrain modification, water level regulation, vegetation control, and automatic auxiliary monitoring of waterbirds. Since its establishment, TZN720 has attracted a large number of waterbirds, with a single record of 188500 waterbirds in 2024. Our successful experience of this project has been included in the “Biodiversity 100+Cases” released at the 15th Conference of the Parties to the Convention on Biological Diversity (CBD-COP15) NGO Forum.

Supported by China’s national and provincial forestry departments, the project trains local youth as monitors and forms community teams. Over 130,000 early warnings have been issued, helping reduce human-elephant conflict and improving safety.

It contributes to GBF Targets A, B, and 1, 4, 20, 21. It strengthens biodiversity protection, enhances community engagement, and offers a scalable model for coexistence.

Himalayan wolf conservation. Human-carnivore conflict mitigation to support traditional Tibetan mountain communities face global warming

Carnivores are among the most endangered species. The loss of apex predators jeopardizes global biodiversity. The Himalayan wolf (Canis lupus chanco) inhabits ecosystems highly vulnerable to climate change. The survival of the Himalayan wolf depends on human-carnivore coexistence and the systems ability to adapt to climate change impacts on the Himalayan ecosystem.

Our Solution aims to improve the livelihood of local Tibetan communities and promote human-carnivore coexistence. We achieve this through scientific research in collaboration with locals; forming Community Conservation Groups (CCG); building communal predator-proof livestock corrals (co-funded by the local communities), piloting fox lights, conducting conservation workshops for herders, women, and school children and installing mini-libraries in local schools. This Solution for fostering human-carnivore coexistence in the high Himalayas is part of an ongoing long-term science and conservation project, the Himalayan Wolves Project (www.himalayanwolvesproject.org).

Leveraging Remote Sensing for Ecological Management and Conservation at Jiangsu Yancheng Wetland & Rare Birds National Natural Reserve

Jiangsu Yancheng Wetland & Rare Birds National Natural Reserve is home to the critically endangered Grus japonensis and other rare species, dependent on wetland mudflat ecosystems. However, invasive species like Spartina alterniflora threaten biodiversity, causing ecological degradation and diminishing biodiversity. To address this, remote sensing technology is used to monitor vegetation evolution, offering valuable insights for ecological management.

Yangtze River Delta Pilot Site of the UN Ocean Decade’s CoastPredict Program, led by Nanjing Normal University, combines remote sensing technology and conservation efforts to support management in Yancheng. Remote sensing has tracked the evolution of key wetland vegetation (Spartina alterniflora, Suaeda salsa, and Phragmites australis) since 1990, helping to understand environmental impacts, human activities, and species interactions. This initiative aids in developing more effective conservation strategies, benefiting both the reserve and broader global effort.

The Mamba: A Drone-based Robotic Arm to Preserve Endangered Plants in Cliff Environments

Tropical islands are home to unique floras, and host a vast number of endemic plant species. Threats have led to a significant population decrease in Hawaii, where 97% of these endemic plant species are listed as endangered, critically endangered, or extinct. Vertical cliff habitats work as refugia to protect plants from these threats. However, these habitats make conservation work particularly difficult, forcing botanists to use risky and time-consuming methods such as abseiling to access remote plant populations. We developed the Mamba, the first aerial system capable of sampling plants on cliffs. The system has allowed the collection of seeds from many critically endangered species including Hibiscadelphus woodii, as well as the recent discovery of a new species: Schiedea waiahuluensis. The conservation collections made by this tool are thriving in nurseries, demonstrating the impact on the conservation cycle for organisms located in difficult-to-reach environments, and the actions necessary to prevent plant extinction.
