Precious orchids and medicinal plants

Paphiopedilum helenae Aver. – Critically Endangered (CR) in IUCN Redlist

Paphiopedilum helenae Aver. is one of the smallest slipper orchids among paphiopedilums. The combination of surprisingly miniature plants with large yellow flowers makes Paphiopedilum helenae being collected for ornamental purposes and commercial use.


Just like other paphiopedilums, this slipper orchid species has been seriously exploited in most of its natural range that leads to the significant decrease of population. The previous study estimated that the number of mature individuals has reduced 85-90% over the last decade. The decline is continuing and there is a projected decline of 80-90% of remaining individuals in the next 25 years.

What CCD is doing: 

Center for Nature Conservation and Development (CCD) conducted a field survey to assess distribution and identify threats to the P. helenae population in Trung Khanh district of Cao Bang province. CCD is continuing to conduct further field surveys on population and especially collecting and trade status of paphiopedilums to gain comprehensive information to propose proper protection and recovery measures in their distribution areas. Research and conservation of endangered orchids is part of the Plant Conservation Programme, which CCD is implementing in many regions of the country. 

Threatened tree species

– Dalbergia oliveri Gamble x Prain –  Endangered (EN) in IUCN Red list. Asian rosewood is widely distributed in Vietnam, Thailand, Laos and Myanmar. This is a hard, beautiful, durable rosewood species containing aromatic essential oils and, free from termites. Therefore, Dalbergia oliveri has high economic value and is at high risk of extinction due to uncontrolled exploitation.

Threats: Dalbergia oliveri is a precious rosewood species and therefore is a target for exploitation. The number of mature individuals has significantly decreased because of over-exploitation. Moreover, deforestation has caused serious damage to its habitat. The remaining population could only be found in some protected areas in the Central and Southern provinces. However, it is scatteredly distributed with low density. 

Dalbergia cochinchinensis Pierre – Vulnerable (VU) in IUCN Red list. Siamese rosewood was widely distributed in Vietnam, Thailand, Laos and Cambodia. This rosewood species is hard, durable, fine texture, beautiful and termite-resistant. D. cochinchinensis has high economic value and has been used to produce high-end reproduction furniture, flooring and handicrafts.

Threats: D. cochinchinensis is a precious rosewood species, therefore it has been exploited for commercial purposes. The number of mature individuals has significantly declined. Moreover, deforestation and habitat fragmentation has seriously compromised the occupation of the species.

What CCD is doingCCD implemented a series of studies on population and natural regeneration of D. cochinchinensis and D. oliveri; assessed the current conservation and management measures to develop a long-term conservation program on these threatened species. CCD will continue our effort on supporting conservation of Dalbergia species through strengthening capacity for stakeholders, enhancing in-situ conservation and facilitating an effective recovery program in their natural habitat.
