|Scientific Name:||Micrurus fulvius|
|Species Authority:||(Linnaeus, 1766)|
|Taxonomic Notes:||Micrurus tener formerly was included as a subspecies of M. fulvius. Crother et al. (2000), Collins and Taggart (2002), and Campbell and Lamar (2004) recognized M. tener and M. fulvius as distinct species.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Cox, N., Chanson, J.S. & Stuart, S.N. (Global Reptile Assessment Coordinating Team)|
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species occurs in the south of the United States, extending into northeastern Mexico. It ranges from southeastern North Carolina to southern Florida, west to southeastern Louisiana, disjunctly northward to central Alabama (Ashton and Ashton 1981, Mount 1975, Dundee and Rossman 1989, Palmer and Braswell 1995, Tennant 1997, Campbell and Lamar 2004).|

|Population:||This species is represented by a large number of occurrences (subpopulations). On a range-wide scale, Campbell and Lamar (2004) mapped more than 100 collection sites. The adult population size is unknown but presumably exceeds 100,000. Nearly 2,000 were turned in for bounties in a 39-month period in one county in Florida (see Ernst and Ernst 2003). This snake is often common; its secretive habits may give a false impression of rarity (Ernst 1992). Mount (1975) characterized it as relatively common in the lower Coastal Plain of Alabama. Tennant (1997) reported it as common in Florida. Population trends are not documented, but its extent of occurrence, area of occupancy, number of subpopulations, and populations size are probably relatively stable or declining at a rate of less than 10% over 10 years or three generations.|
|Habitat and Ecology:||Habitats include hardwood forest, pine-oak woodland, pine flatwoods, and xerophytic scrub, often in areas with sandy soils, sometimes marsh edges and residential areas (Mount 1975, Ashton and Ashton 1981, Palmer and Braswell 1995, Tennant 1997, Ernst and Ernst 2003). This secretive snake is often underground, under leaf litter, logs or stumps, or similarly secluded. Eggs probably are laid in loose soil or decaying organic matter (Mount 1975), or underground or under leaf litter or surface objects (Ernst 1992).|
|Major Threat(s):||Overall, this species does not appear to be significantly threatened. In Alabama, populations declined after introduction of the fire ant, which may prey on eggs and young (Mount 1981). Habitat destruction and motorized vehicles are the most serious threats (Ernst 1992, Ernst and Ernst 2003).|
|Conservation Actions:||Many occurrences are in protected areas.|
