Taxonomic Comments
Lasiurus seminolus was treated as a distinct species by Jones et al. (1992) and Koopman (in Wilson and Reeder 1993), though Koopman noted that seminolus probably is only a subspecies of L. borealis.

Threat ImpactLow
Range Extent200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Rank Reasons
Large range primarily in southeastern United States; many roosting sites and locations; common, presumed large population size; trend uncertain but likely relatively stable or slowly declining; no major threats.
Range Extent Comments
Range includes the southeastern United States from eastern Texas east to the Atlantic Coast, south to southern Florida, and north to Oklahoma (rarely encountered), Arkansas, Tennessee (rarely Kentucky), North Carolina, and southeastern Virginia (Wilkins 1987, Padgett and Rose 1991). Extralimital records exist for southeastern Pennsylvania, Ithaca (New York), Bermuda, and (unverified) Veracruz, Mexico. This species has not been recorded at elevations above 500 meters.
Occurrences Comments
The number of distinct occurrences has not been determined using standardized/meaningful criteria, but this species is represented by a widely distributed and large number of collection and observation sites and locations (as defined by IUCN).
Threat Impact Comments
No major threats are known. Over the long term, deforestation undoubtedly has reduced the available habitat for this species. However, much suitable forest habitat remains. This species remains common in most of its range, and it persists in managed forests.

Broadcast application of pesticides to combat forest/tree insect pests potentially has a detrimental impact on this species and its food resources; range-wide population impact is unknown.

Commercial collecting of Spanish-moss and other factors that reduce the abundance of this lichen have been cited as threats, but recent studies indicate that Spanish-moss is not as important for roosting as previously believed (see habitat comments).

Relatively low numbers of this species have been found dead near turbines at wind energy facilities. Arnett and Baerwald (2013) estimated that approximately 1,100-2,300 individuals were killed by turbines in the United States and Canada during the period 2000-2011. Presumably the impact of wind energy fatalities will increase to some degree with the ongoing expansion of installed wind energy capacity.

This species is unlikely to be affected by white-nose syndrome (a cold-loving fungus that afflicts bats hibernating in caves and mines).
Ecology & Habitat

Habitat

Habitats include pine, mixed pine-hardwood, and hardwood forests of uplands and bottomlands, particularly pine-dominated forests, including mature pine and pine-hardwood corridors in managed pine forest landscapes (Menzel et al. 1998, 1999, 2000; Carter et al. 2004; Marks and Marks 2006; Perry and Thill 2007; Perry et al. 2007; Hein et al. 2008; Ammerman et al. 2012). Foraging occurs over water, clearings, and woods, including pine stands and upland and bottomland hardwoods (Carter et al. 2004). During autumn through spring, these bats commonly can be found in and near forests that support clumps of Spanish-moss (Jennings 1958). Roosts are up to 19 meters above ground in tall, large-diameter trees, but seasonally the bats may roost near or on the forest floor. In summer, roosts include clumps of needles on small branches in the canopy of large pines (often slash pine or loblolly pines; roosting bats may resemble pine cones) (Menzel et al. 1998, 1999, 2000; Perry and Thill 2007; Perry et al. 2007; Hein et al. 2008). Sometimes the bats have been found in clumps of Spanish-moss (mainly autumn through spring) (Constantine 1958, Jennings 1958). Winter roosts of adult males in South Carolina were in the canopy of overstory trees, understory vegetation, pine needle clusters, and leaf litter; bats roosted near or on the forest floor during cold weather, sometimes staying in one roost for up to 12 consecutive days (Hein et al. 2005, 2008). Individuals often switch among roosts in close proximity but may return to previously used trees or roost sites (Menzel et al. 2000, Perry and Thill 2007, Hein et al. 2008).

Ecology

Roosting occurs solitarily (single individual or a female with young).

Reproduction

Copulation occurs in fall and probably in winter and spring as well (Constantine 1958). Females may carry 1-4 embryos but give birth usually to 2 young (Davis 1974) in May-June. Young are able to fly in 3-4 weeks.
