Assessor/s: Hammerson, G.A., Mendoza-Quijano, F. & Lee, J.
Reviewer/s: Bowles, P.
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
History:
2007 Least Concern

Population [top]

Population: This species is represented by a very large number (hundreds) of occurrences or subpopulations (see map in Christman 1982). The total adult population size is unknown but undoubtedly far exceeds 100,000. This snake is locally abundant (up to hundreds per hectare) in many areas. Its extent of occurrence, area of occupancy, number of subpopulations, and the population are probably relatively stable.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This snake occurs in nearly all terrestrial and wetland habitat types in its range, including cities. Habitats in Mexico include cloud forest and tropical deciduous forest. Usually it inhabits moist situations, but it is not an aquatic species. It often occurs under debris or logs; frequently among water hyacinths in Florida. Hibernation sites (often communal) are underground or beneath buildings and other structures.
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats known for this species. This snake tolerates a high level of habitat disturbance.

Conservation Actions [top]

Conservation Actions: Many occurrences of this species are in protected areas.
