Scientific Name: Mangifera minutifolia Evrard
Taxonomic Source(s): Kostermans, A.J.G.H. and Bompard, J.-M. 1993. The Mangoes. Academic Press Ltd., London.
Taxonomic Notes: Mangifera minutifolia Evrard. belongs to Taxon Group three of Mango M. indica L. This species was considered of doubtful validity by Muhkerjee (1985).

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2016
Date Assessed: 2014-01-01
Assessor(s): Rhodes, L. & Maxted, N.
Reviewer(s): Fielder, H. & Dillon, N.
Justification:
This species is globally assessed as Endangered (B2ab(iii)). It has only ever been recorded in one site in a threatened habitat and so is assumed to be under threat itself, and therefore occurs in one location. A previous Red List assessment reported that the species was Vulnerable and met criterion D2 i.e. that its area of occupancy (AOO) was less than 100 km2 and/or it occurred in fewer than five locations (WCMC 1998). With an AOO of 100 km2 or less and occurring in one location within a threatened habitat, this species meets criterion B2ab(iii) under the Endangered category.

To conserve Mangifera minutifolia, urgent survey work should be undertaken in situ to locate the site where the type specimen of this species was found and to ascertain whether or not its range extends any further than this. Once located and its full range known, active population management and monitoring will be a high priority to ensure long-term survival of the species.

Population [top]

Population:This species was classified as Vulnerable (D2) in a previous global assessment (WCMC 1998). This means that it has a very restricted population, with either an area of occupancy (AOO) of less than 100 km2 or occurring in fewer than five locations (or both). It is possible that it occurs in only one location as it is only known from one type specimen and its habitat is threatened. This would also suggest that its AOO is very restricted. An ecogeographic survey is required to determine whether the species is still extant in this locality and if its range extends beyond this site.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Population severely fragmented:Unknown
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:UnknownAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:From the collection site of the type specimen this species is presumed to be restricted to dry, lowland forests of Viet Nam, a habitat classified as threatened and the most degraded dry forest ecoregion outside of India (Kostermans and Bombard 1993, WWF 2013).
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: Mangifera minutifolia belongs to Taxon Group three of the cultivated Mango M. indica (Kostermans and Bompard 1993) and so it has the potential for use as a gene donor for crop improvement.

Threats [top]

Major Threat(s): This species was globally assessed as Vulnerable (D2) in 1998 (WCMC 1998). It is suspected to occur in the southern dry forest ecoregion of Viet Nam, which is highly threatened and severely degraded, having lost more than 90% of its habitat due to the clearing of forests (WWF 2013). The same source states that this is primarily due to the conversion of land for agriculture and the exploitation of valuable hardwood trees and other plant resources, remaining forest habitat is also surrounded by human settlements and so is subject to many anthropogenic pressures.

Conservation Actions [top]

Conservation Actions: There is no evidence of in situ or ex situ conservation for this species as it has only once been recorded. More generally, just two percent of the dry forest ecoregion in which it is thought to occur falls within protected areas, but in reality the protected areas offer little protection and are becoming more and more fragmented (WWF 2013).
