Habitat:
This aquatic species inhabits shallow, muddy, weed-choked water, including swamps, ponds, lakes, streams, and artificial ditches. It is found among thick vegetation, under rocks and logs, or burrowed in bottom mud by day. It is also known to burrow into bottom mud if the surrounding water dries up. The eggs are laid in water in small clusters on the bottom. There is no information on its habitat or ecology in Mexico. This species can survive in modified habitats.
Range:
This species occurs in the coastal plain from the District of Columbia through Florida and southern Alabama in the United States of America (Conant and Collins 1991). Specimens occurring in the Rio Grande Valley (from Upson, Maverick county to Brownsville, Texas, and Matamoros, Tamaulipas, Mexico) were tentatively assigned to this species by Flores-Villela and Brandon (1992). According to genetic analysis, there are no confirmed differences in blood proteins and mtDNA between Siren intermedia and S. lacertina in the Rio Grande subpopulation (Dixon 2013). Therefore, further taxonomic work is needed to confirm the identity of this subpopulation in the border region between Tamaulipas-Texas (A. Calzada and S. Terán Juárez pers. comm. October 2019). Due to this taxonomic confusion, this record has been retained in the map as "Presence Uncertain." Its elevational range is unknown. Additionally, this species was previously reported to occur in Maryland, however this report was made in error (Maryland Natural Heritage Program 2016).
Conservation:
Conservation Actions In-Place
This species occurs in several protected areas in the United States, but has not been recorded from any protected areas in Mexico. This species is protected by Mexican law under the "Threatened (Amenazada)" category (A).
Conservation Needed
This species would likely benefit from improved habitat protection at sites where it is known to occur. Proactive, precautionary steps should be taken to detect the arrival of Bsal in Mexico through the swabbing of both wild and imported salamanders, in addition to a total ban on the importation of non-native salamanders (Mexico Red List Assessment Workshop October 2019).
Research Needed
More information is needed on this species' distribution, population status, ecology and threats. Taxonomic work is required, specifically to confirm the identity of the Tamaulipas-Texas border region subpopulation (S. Terán Juárez and A. Calzada pers. comm. October 2019).
