Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA PINOPSIDA PINALES PODOCARPACEAE

Scientific Name: Nageia fleuryi
Species Authority: (Hickel) de Laub.
Synonym/s:
Podocarpus fleuryi Hickel
Taxonomic Notes: This species is not easily distinguished from the much more widely distributed species Nageia wallichiana and several records, if not backed by good herbarium material, may be unreliable.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2013
Date Assessed: 2011-11-09
Assessor/s: Thomas, P.
Reviewer/s: Farjon, A. & Nguyen, T.H.
Justification:
Widely distributed but with disjunct populations throughout northeast Viet Nam, Lao PDR and southeast China. The extent of occurrence falls outside the threshold for Vulnerable and no estimates exist for the area of occupancy. The timber is valued and is being selectively logged in significant parts of its range. A past decline of up to 29 % is likely to have occurred within the last three decades especially in the southern parts of its range. Although generation lengths are uncertain, it is highly probable that a single generation length would exceed 30 years. On this basis it is assessed as Near Threatened as it almost qualifies as Vulnerable under criterion A2d.
History:
2007 Near Threatened
2002 Data Deficient
1997 Vulnerable (Walter and Gillett 1998)

Geographic Range [top]

Range Description: Recorded from China: Guangdong (Gaoyao, Longmen, Zengcheng), Guangxi (Hepu), Yunnan (Mengzi, Pingbian); Viet Nam and Lao PDR (Thomas et al. 2007). Reports of this species from Cambodia are likely to be the result of misidentifications with Nageia wallichiana. The extent of occurrence is considerably in excess of 20,000 km2. No credible estimates for area of occupancy have been made. It is known from more than 10 locations.

Population [top]

Population: This species occurs as small disjunct subpopulations in forest remnants.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Most often found on limestone formations (karst) in mixed angiosperm/conifer forest; also in montane tropical rainforest dominated by evergreen broadleaved angiosperm trees. Recorded from 500 up to 1,200 m asl.  In some parts of its range, selective logging and deforestation has led to a decline in the area of occupancy, the quality of habitat and probably the number of mature individuals.
Systems: Terrestrial

Threats [top]

Major Threat(s): Selective logging, habitat disturbances, and deforestation are the main threats.

Conservation Actions [top]

Conservation Actions: This species is known from a few protected areas in northern Viet Nam, Lao PDR and China. The percentage of the total population within these areas is unknown. A limited amount of in situ conservation work has been initiated in northern Viet Nam. Further field work and monitoring of existing subpopulations is needed.
