Assessment Information
Red List Category & Criteria:
Least Concern ver 3.1
Year Published:
2011
Date Assessed:
July 22, 2011
Justification:
Pomacea glauca has been assessed as Least Concern as it is widely distributed with no current
widespread threats negatively impacting its global population. Further research on the population
trends, life history, ecology and threats impacting the species would be helpful.
Geographic Range
Range Description:
Pomacea effusa glauca is found in the Dominican Republic, Lesser Antilles, and northern South America
from Bolivia, Colombia and Venezuela through Guyana, Suriname and French Guiana (Perera and Walls
1996). It is unknown whether this species spreads further south into the Amazon (Perera and Walls
1996). It has also been recorded in Trinidad, Grenada, Guadaloupe, and Martinique (Cowie and Thiengo
2003).
Pomacea effusa cumingi is found in Chiapas, Mexico and Panama (Ghesquiere 2007).
Country Occurrence:
Native: Bolivia, Plurinational States of; Colombia (Colombia (mainland)); Dominican Republic; French
Guiana; Grenada; Guadeloupe; Guyana; Martinique; Mexico (Chiapas); Panama; Suriname; Trinidad and
Tobago; Venezuela, Bolivarian Republic of (Venezuela (mainland))

Population
There is no population information available for this species.
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
Pomacea effusa glauca inhabits clean, clear water, including flowing water streams, canals and ditches,
but reaches its highest densities in lake environments (Perera and Walls 1996). The eggs are bright
green. It is a voracious eater and consumes almost all plants and regularly leaves the water for land
(Perera and Walls 1996).
The eggs of Pomacea effusa cumingi are deposited above the water line (Gheresquiere 2007).
Systems: Freshwater
Threats (see Appendix for additional information)
It is unknown whether there are any major threats to this species. However, it is likely that this species is
experiencing localized declines due to urbanization, habitat degradation and alterations to the
hydrological regime.
Conservation Actions
Pomacea effusa glauca has been used as a biological control agent for aquatic plants due to its
voracious appetite (Perera and Watts 1996). Further research is required to determine the abundance of
this species, and whether it is impacted by any major threats. It is unknown whether there are any
conservation measures in place for Pomacea effusa cumingi. Further research is required to determine
the abundance of this species, its ecology and whether it is impacted by any major threats.
