The
Lacey Act of 1900, or simply the Lacey Act () is a
conservation law in the
United States. Introduced into
Congress by
Rep. John F. Lacey, an
Iowa Republican, the act was signed into law by President
William McKinley on May 25, 1900. The Lacey Act protects both plants and wildlife by creating civil and criminal penalties for a wide array of violations. It prohibits trade in wildlife, fish, and plants that have been illegally taken, transported or sold. The law is still in effect, although it has been amended several times.
Invasive species, also called invasive exotics or simply exotics, is a
nomenclature term and categorization phrase used for
flora and
fauna, and for specific restoration-preservation processes in native
habitats, with several definitions. The first definition, the most used, applies to
introduced species (also called "non-indigenous" or "non-native") that adversely affect the
habitats and
bioregions they invade economically, environmentally, and/or ecologically. Such invasive species may be either plants or animals and may disrupt by dominating a region,
wilderness areas, particular
habitats, or
wildland–urban interface land from loss of natural controls (such as
predators or
herbivores). This includes non-native invasive plant species labeled as exotic pest plants and invasive exotics growing in native
plant communities. It has been used in this sense by
government organizations as well as conservation groups such as the
International Union for Conservation of Nature (IUCN) and the
California Native Plant Society. The
European Union defines "Invasive Alien Species" as those that are, firstly, outside their natural distribution area, and secondly, threaten
biological diversity. It is also used by land managers, botanists, researchers, horticulturalists, conservationists, and the public for
noxious weeds. The
kudzu vine (
Pueraria lobata),
Andean Pampas grass (
Cortaderia jubata), and
yellow starthistle (
Centaurea solstitialis) are examples. ==Provisions of the bill==
