At the federal level, the primary statute governing the protection of wildlife species in the United States is the Endangered Species Act (ESA) of 1973. The Slimy Salamander (Plethodon glutinosus sensu stricto) is not currently listed as threatened or endangered under the ESA, reflecting the species' broad distribution and generally stable population across much of its range in the central and southern Appalachian region. However, the dissolution of the old broad Plethodon glutinosus concept into a complex of over sixteen species has introduced significant legal and regulatory nuance. Several members of the species complex have much more restricted ranges and face greater conservation threats than the nominate species, and the legal status of these narrowly distributed relatives varies.
The Lacey Act, originally enacted in 1900 and subsequently amended, provides an additional federal framework relevant to the Slimy Salamander. This statute prohibits the interstate transport of wildlife taken in violation of state or foreign law. For practical purposes, this means that a Slimy Salamander collected illegally under the regulations of one state cannot be legally transported across state lines, even if possession of the species would be lawful in the destination state. The Lacey Act thus functions as a federal backstop that reinforces the patchwork of state-level regulations governing amphibian collection and possession.
The National Environmental Policy Act (NEPA) also intersects with Slimy Salamander conservation in cases where federal agency actions, such as highway construction, dam projects, or national forest management plans, have the potential to affect the species' habitat. Environmental impact assessments conducted under NEPA are required to consider effects on wildlife, including common species such as the Slimy Salamander, when proposed actions would significantly alter forest floor conditions. The species' role as an indicator of forest health has led to its inclusion in biological assessments for projects on national forest lands in the Appalachian region, even when it is not formally listed under the ESA.
It is important to note that federal protections apply not only to the species itself but also to its critical habitat when that habitat occurs on federally managed lands. National forests, national parks, and other federal land units within the Slimy Salamander's range are governed by management plans that include provisions for the conservation of native amphibian communities. Collection of salamanders on federal lands is typically prohibited without a specific scientific collecting permit, regardless of whether the species involved is listed under the ESA.
