- UPDATING THE DONG NAI FLORA CHECKLIST: SAFEGUARDING FORESTS, BIODIVERSITY VALUES, AND WATER SECURITY
In 2025–2026, the Center for Nature Conservation and Development (CCD) and the Dong Nai Culture–Nature Reserve will survey and update the flora checklist, focusing on the distribution of rare and valuable timber species. Using seasonal surveys, transects/standard plots, and a voucher set of specimens - photos - GPS, the team will determine species composition and the level of plant community diversity. Results will delineate critical habitats and identify priority species for mother-tree protection, seed collection, native nursery production, and restoration of depleted taxa; in parallel with the checklist update, the team will collect additional representative vouchers for scientific reference, exhibits, and education–awareness at the reserve. In addition, CCD is implementing key conservation programs in Dong Nai: monitoring threatened fauna in Cat Tien National Park; restoring valuable timber species such as Dalbergia oliveri and Siamese rosewood (Dalbergia cochinchinensis) within the Reserve; and strengthening the two management boards’ capacity on patrolling, forest protection, and ecotourism. The Dong Nai Culture–Nature Reserve (>100,000 ha), adjacent to Cat Tien National Park, is among the remaining primary forest ecosystems of Southeastern Vietnam and a vital headwater forest of the Dong Nai River system. Safeguarding Dong Nai’s forests is preserving the core values of the Southeast region—a priceless natural heritage for today and for generations to come.
- SURVEYING THE CURRENT STATUS OF GAUR, BANTENG, AND SILVER-BACKED CHEVROTAIN POPULATIONS AT EA SO NATURE RESERVE
As part of the biodiversity survey activities at Ea So Nature Reserve, and part of the CCD's UNGULATE CONSERVATION PROGRAM, our community-based FOREST PROTECTION AND BIODIVERSITY MONITORING team and experts from the Center for Nature Conservation and Development (CCD) and staff of Ea So Nature Reserve. In September, the Monitoring Team conducted its first field trip to collect data on the current status of Gaur (Bos gaurus), Banteng (Bos javanicus), and Silver-backed Chevrotain (Tragulus versicolor), while also monitoring negative human impacts within Ea So Nature Reserve. The survey used camera traps, GPS, and the SMART data management and patrol reporting toolkit (SMART) in combination with standard data recording methods. The Monitoring Team consulted information from local residents and forest rangers working in the area and recorded reports of the presence of wild Cattle (Bos spp.) in several sub -compartments. Based on this preliminary information, the Team designed survey transects focusing on grassland habitats - the characteristic and most suitable habitat for the ecological behavior of bovids, which use grasslands for foraging, resting, and movement -thereby increasing the likelihood of detecting signs or encountering individuals. For the Silver-backed Chevrotain, camera traps will be retrieved after two months to obtain accurate results, as data from camera traps require a sufficiently long accumulation period. In parallel with the wild cattle surveys, the Monitoring Team also documented human impacts within the protected area. Illegal activities such as timber extraction, hunting, or setting traps for wildlife were observed, recorded, and georeferenced to support assessments of threat levels to animal populations. This is an opportunity for staff of Ea So Nature Reserve to practice species identification and classification, as well as to select survey transects, deploy camera traps, and manage and archive data. In the long term, these skills will help improve the effectiveness of biodiversity conservation, and protect the forest ecosystem and its rare and precious flora and fauna.
- Protecting and Restoring the Delacour’s Langur (Trachypithecus delacouri) Population in Kim Bảng, Hà Nam
Since 2019, Center for Nature Conservation and Development (CCD) has collaborated with local Forest Protection authorities to implement a program to monitor and protect the Delacour’s langur (Trachypithecus delacouri) population and the surrounding limestone forest ecosystem in Kim Bảng, Ninh Bình province. This is a long-term, community-based conservation initiative, centered on establishing community forest protection teams to conduct regular and continuous monitoring of langurs and their limestone habitat. Kim Bảng lies within the extensive limestone karst ecosystem stretching from Thanh Hóa and Phú Thọ (formerly Hòa Bình) through Ninh Bình to Hà Nội. This area plays a critically important role in the conservation of the Delacour’s langur. In fact, Kim Bảng hosts Vietnam’s second most significant langur population, with over 100 individuals recorded to date. Within the framework of the Delacour’s Langur Conservation Project, funded by Conservation Vietnam, CCD has worked closely with the Forest Protection Department of Area IV (formerly FPD Kim Bảng) to carry out key activities: Establishing community-based forest protection teams Conducting monthly patrols to monitor langur groups and their behavior Removing snares and traps and documenting signs of illegal activities in a timely manner Information collected during patrols is shared with forest rangers to coordinate law enforcement and reduce threats to langurs and local biodiversity. Alongside patrols, the project team conducts awareness-raising campaigns in schools and local communities to improve understanding and encourage local participation in protecting langurs and limestone habitats. In the coming period, CCD will continue to collaborate with the Forest Protection Sub-Department and community groups to: Maintain field-based protection and monitoring efforts Strengthen outreach and communication, and minimize negative impacts on limestone habitats Support local authorities in reviewing and finalizing documentation to propose the establishment of a Species and Habitat Conservation Area for the Delacour’s langur in Kim Bảng.
- Assessment of current management practices and conservation status of Dalbergia cochinchinensis and D. oliveri in Gia Lai, Kon Tum and Dak Lak provinces
Vietnam’s wildlife has undergone a long period of over exploitation. As a result, populations of many species have been seriously declined and some of them such as Javan rhinoceros (Rhinoceros sondaicus annamiticus) and Kouprey (Bos sauveli) were extinct. Sharing similar situation, many of the country’s flora are under high pressure of exploitation to fill the needs of the market that lead many plant species to brink of extinction. In Vietnam, rosewood (Dalbergia spp.), ladys’s slipper orchids (Paphiopedilum spp.) and marbled jewel orchids (Anoectochilus spp.) are among the most threatened wildlife due to illegal logging and trade. The Center for Nature Conservation and Development (CCD) has been running a long-term program to support the protection and recovery of endangered wild fauna and flora with a focus on strengthening in-situ conservation and improving the effectiveness of law enforcement efforts to effectively prevent illegal hunting, logging and trafficking of Vietnam’s endangered species of wild flora and fauna that being trafficking from and through the country. In September 2019, CCD in cooperation with Vietnam CITES management agency conducted an assessment of management, protection and conservation efforts for the highly threatened Dalbergia cochinchinesis and Dalbergia oliveri in Dak Lak, Gia Lai and Kon Tum provinces. The findings indicated that the populations of these two species have been rapidly declined in all original known distribution areas due to over-exploitation for high-end furniture and handicraft products. In Kon Tum province, a biggest natural population of Dalbergia cochinchinesis is only found in Dak Uy forest where it has already been gazette as Special Use Forest (also called as protected area) in an area of 546.24 ha. The protected area possesses about 800 matured Dalbergia cochinchinesis trees (>20cm in diameter) and many younger trees. Dalbergia cochinchinesis was found to be scattered distributed in other areas of Kon Tum province. In Gia Lai province, the population of Dalbergia cochinchinesis has dramatically reduced and only remained few mature individual trees in a scattered forests and some found in local forest land own by households in Krong Pa district. Some mature Dalbergia cochinchinesis trees (> 20cm in diameter) are reported to be in Kon Ka Kinh national park and Kon Chu Rang nature reserve. In Dak Lak province, the trees with diameter greater than 20cm are found in Yok Don national park, Ea So nature reserve and Krong Nang watershed protection forests with low density. Other areas have few scattered mature trees and regenerated trees but quite fragmented. In terms of conservation efforts, there is only Kon Tum province that has a conservation program of Dalbergia cochinchinesis. The province established Dak Uy protected area to protect this species. In 2018, the province planted 4,500 seedlings within the protected area and 6,600 seedlings in other places. Gia Lai and Dak Lak provinces have not got any conservation or restoration program for Dalbergia cochinchinesis. It is the same as the Dalbergia cochinchinesis, the Dalbergia oliveri has been logging for making furniture products and fine arts. Dalbergia oliveri became the main subject of exploitation when the source of Dalbergia cochinchinesis timber is exhausted. In three surveyed provinces, the population of Dalbergia oliveri has been degraded and is only found in protected areas with low density. In Kon Tum province, Dalbergia oliveri are reported in Chu Mom Ray national park, Dak Uy protected area and watershed protection forest of Dak To, Dak Ha and Ngoc Hoi districts. In Gia Lai province, Dalbergia oliveri distributes in Kon Chư Răng, Kon Ka King, and watershed protection forest of Krong Pa and Chu Pah districts. In Dak Lak, Dalbergia oliveri is remained in Yok Don national park, Ea So nature reserve and Chu Yang Sin national park as well as other watershed protection forests. Forest plantation programs of all three provinces have not got this species. There are few propagation activities of these two species. However, only one propagation facility was found in the three province that was at the Center for Tropical Forestry in Gia Lai province. The survey also found that some families in Krong Pa district are protecting regenerating trees Dalbergia cochinchinesis in their cashew plantation, however, this is in small scale. All three provincial FPDs elaborated that there is absolutely no exploitation of rosewood from natural forests. However, some illegal activities such as collection of remaining roots and stumps of previously logged rosewood trees, are still occurred with small amount. Obviously, threats to rosewood are remaining. Without stronger forest protection and effective forest recovery efforts, these two species of rosewood may vanish from their traditional distribution areas soon.

- CONSERVATION OF WILD BIRDS IN THE RED RIVER FLOODPLAIN
The section of the Red River flowing through Hanoi spans approximately 120 km, encompassing a variety of habitats such as sandbanks, reed grasslands, and water channels along the riverbanks and on mid-river islets. These areas are critical natural habitats for many species of wild birds. The floodplains and islets serve as essential living, feeding, and wintering grounds for both resident birds and migratory birds traveling along the East Asia - Australasia Flyway, including numerous Endangered & Critically Endangered species. Picture 1-2 : CCD is collaborating with forest protection departments and local authorities to collect, destroy mist nets along the Red river in Hanoi ©CCD/2025 One of the annual activities of the Center for Nature Conservation and Development (CCD) is collaborating with the Hanoi Forest Protection Department to conduct communication campaigns promoting the protection of wild birds in the floodplain areas, particularly in regions frequented by migratory birds. Alongside these outreach efforts, during the migratory bird seasons, CCD works with the Hanoi Forest Protection Department and local authorities to implement monitoring and conservation programs in the floodplain regions. These programs include removing bird-trapping nets and preventing activities that destroy natural habitats in these areas. Picture 2: Mist nets are setup by hunters along the Red river in migratory season Picture 3: Some insects are unable to circumvent the destruction of mist nets ©CCD/2024 CCD has also proposed that the Hanoi People's Committee establish wild bird conservation areas and natural parks on the floodplains and mid-river islets of the Red River. These parks and conservation zones would not only provide Hanoi with more green spaces but also serve as venues for educational activities for students and as opportunities for citizens and visitors to engage with nature and the environment in the capital.
