|Scientific Name:||Albizia glabripetala (H.S.Irwin) G.P.Lewis & P.E.Owen|
Pithecellobium glabripetalum H.S.Irwin
|Red List Category & Criteria:||Least Concern ver 3.1|
Albizia glabripetala is a tree which occurs in Venezuela, Guyana, Suriname and Brazil. The estimated extent of occurrence (EOO=230,000 km²) does not meet the threshold for a threatened category, as the species shows a wide distribution range at present and there is not enough data about population numbers and trends to infer and quantify a possible population reduction, therefore the species is currently rated as Least Concern. Further research and field work are required to better understand distribution, health and dynamics of A. glabripetala, which, being a riverside species, might be affected by the increasing gold mining in the regions and by the mercury contamination of soil and river sediments.

|Population:||The species has been described as occasional along river in Venezuela (Fenix and Wurdack #41263).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||A. glabripetala is a tree, 10-12 m high, which grows in riverine forest on sandy banks, seasonally flooded forest and in low (3-4 m tall) carrasco woodland.|
A. glabripetala is known to occur in the Guianan moist forests, Guianan savanna, Guianan piedmont and lowland moist forests ecoregions (Olson et al. 2001).
|Major Threat(s):||Recent increases in gold mining have severely impacted streams and surrounding landscapes with polluted runoff and mercury contamination (Schipper et al. 2001).|
There are no known conservation measures specifically for A. glabripetala, but the species is currently known to occur in some protected areas, such as El Caura Forest Reserve (Venezuela) and Maracá Ecological Station (Brazil). Samples of seed of A. glabripetala should be collected and stored in the Millennium Seed Bank as an ex situ conservation measure.
A. glabripetala is listed in the World list of threatened trees (1998) as Lower Risk/near threatened (ver 2.3) and in the Libro Rojo de la Flora Venezolana (2003) the species is listed as one of the species at lower risk.
