Red List Category & Criteria: Near Threatened ver 3.1

Justification:
Dalbergia chapelieri is an endemic species widespread in eastern Madagascar. At present the species does not appear to meet any of the IUCN Criteria for a threatened category. Due to the habitat type where the species grows and to the severe fragmentation and degradation it has been subjected to in the last decades, it is believed that the species is of conservation concern. The decline in the population of this species is also aggravated by the fact that it is logged for its timber and that illegal logging in the country appears to be a serious problem. The species is rated as Near Threatened at present (almost qualifies for listing as threatened under criteria B2ab(iii)), however, it needs to be monitored over a longer period of time to make sure that the decline of the extent and quality of the evergreen forests will not lead the species to a population decline in the future and to listing in a threatened category. The species, may well have a small enough area of occupancy (i.e. under 2,000 km²) but the fact that it occurs in secondary habitat, and that it may coppice after harvesting indicates that it may be tolerant of some levels of disturbance.

Population [top]

Population:The species appears to be widespread across the eastern evergreen forest of Madagascar. A large number of subpopulations are known but the population is becoming increasingly fragmented through deforestation.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:D. chapelieri is a deciduous shrub or small tree up to 15 m high which occurs in evergreen humid forest, littoral forest, on lateritic or sandy soil. It can be found in humid valleys as well as on drier crest and even may survive as a shrub after resprouting in secondary vegetation.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The wood is used for construction, carpentry and furniture. It is also used in traditional medicine to treat parasitic diseases. The bark is sometimes collected and used for tanning hides and dyeing.

Threats [top]

Major Threat(s): This species currently appears to be widespread, but it occurs in humid rainforest, which is a habitat suffering from rapid deforestation and it mainly grows in lowland forests, which are under pressure because of growing human populations. It is estimated that the humid forest has reduced by approximately 33% since the 1970s (Moat and Smith 2007). The species' wood is traded in small amounts in local and international markets, often mixed with the wood of other Dalbergia sp. (Louppe et al. 2008) and it is locally selectively felled for its timber. Therefore, the species dynamic may be already compromised, hence it is highly recommended to carry out further study to assess that the population dynamic and the reproductive success of the species. It has been estimated (Randriamalala and Liu 2010) that in 2009 ca. 52,000 tonnes of rosewood and ebony tree were logged in northeast Madagascar. Because of the low density of rosewood tree per hectare (according to Stasse (2002) the logging pressure on rosewood in Madagascar has lead to decrease the density per hectare and loggers in 2009 were cutting young trees before they could reach the reproductive maturity (Randriamalala and Liu 2010)), loggers have to encroach new areas routinely (Barrett et al. 2010), this also means that illegal logging is being carried out within the protected areas perimeter. The logging process also facilitates the invasion of non-native species, reduces native species diversity and aridifies landscapes.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures specifically for D. chapelieri, but the species is currently known to occur in some protected areas, such as Manombo Special Reserve, Analamazaotra-Périnet Reserve, Andohahela National Park, Betampona Reserve, Midongy du Sud National Park, Pic d'Ivohibe Reserve and Ranomafana National Park. Samples of seed of D. chapelieri should be collected and stored as an ex situ conservation measure. The species has been listed as Vulnerable (A1cd+2cd) in the IUCN Red List of Threatened Species (accessed April 2010) and in the Leguminosae of Madagascar (Du Puy et al. 2002). Further study and field work is required to better define the population size and dynamic of this species. In 2010 the Minister for Environment and Forests submitted a request to the Secretariat of CITES (Convention on International Trade in Endangered Species) to list all Malagasy Dalbergia and Diospyros species (to which ebony, rosewood and pallisander belong) on Appendix III of the CITES convention (Global Witness and the Environmental Investigation Agency (US) 2010).
