Species Lists

The list of “100 of the World’s Worst Invasive Alien Species” is designed to enhance awareness of the fascinating complexity, and also the terrible consequences, of invasive alien species. Species were selected for the list according to two criteria: their serious impact on biological diversity and/or human activities, and their illustration of important issues surrounding biological invasion.

The National CAPS Committee will revise the National Pest Surveillance Guidelines when annually reviewing the policy, strategy, and performance of the CAPS program. The NCC also will approve annually a “Priority Pest List.” This list will include the Commodity and Taxonomic Survey Pests, as well as Pests of Economic and Environmental Importance (OPEP Prioritized List). The Priority Pest List will be based on input by PPQ, the States, Center for Plant Health Science and Technology (CPHST), National Identification Services (NIS), and commodity organizations.

Includes invasive species by category for insects, diseases, plants, and animals.

Provides information on federally and state regulated plants. Refer to the link to the Excel spreadsheet of information compiled by industry for regulated noxious aquatic weeds (combined federal and state list). Please note that state regulations change frequently and may not reflect the most current information.

Introduced (non-native) species that becomes established may eventually become invasive, so tracking introduced species provides a baseline for effective modeling of species trends and interactions, geospatially and temporally.

The United States Register of Introduced and Invasive Species (US-RIIS) is comprised of three lists, one each for Alaska, Hawaii, and the conterminous United States. Each list includes introduced (non-native), established (reproducing) taxa that: are, or may become, invasive (harmful) in the locality; are not known to be harmful there; and/or have been used for biological control in the locality.

To be included in the US-RIIS, a taxon must be non-native everywhere in the locality and established (reproducing) anywhere in the locality. Native pest species are not included. The US-RIIS builds on a previous dataset, A Comprehensive List of Non-Native Species Established in Three Major Regions of the U.S.: Version 3.0 (Simpson et al., 2020). An Open-File Report 2018-1156, 15 p., related to the predecessor of the US-RIIS: https://doi.org/10.3133/ofr20181156.

The existing BISON website was taken down on December 17, 2021 and users are now redirected to Species observations for the United States and U.S. Territories via the new pilot implementation of the Global Biodiversity Information Facility (GBIF-US) data portal.

APHIS created the webpage to make it easier for its customers to find critical information on pests and diseases of concern. With this tool, members of the public will have the information they need to report pests and diseases and together we can protect America’s agriculture and natural resources. This page lists all pest and disease programs managed by APHISas part of its mission to protect American agriculture and natural resources. Users can search by type (plant, animal), keyword (avian, fruit fly, cotton), or by the specific pest or disease (coconut rhinoceros beetle, brucellosis). You can also scroll through the page, which lists the pests and diseases alphabetically and includes a corresponding image.

APHIS regulates the following list of pests under the authority of the Plant Protection Act. It does not include any 'regulated non-quarantine pests' (pests which are present and may be widely distributed in the U.S.

The APHIS Federal Noxious Weed Program is designed to prevent the introduction into the United States of nonindigenous invasive plants.
See also: Noxious Weeds Program Homepage for more information.

Provides fact sheets, maps and collection information for aquatic vertebrates and invertebrates occurring outside of their native range.

Provides information for plants are designated as invasive in Ohio. No person shall sell, offer for sale, propagate, distribute, import or intentionally cause the dissemination of any invasive plant in Ohio. The invasive plants are first designated by the plant's botanical name and then by the plant's common name.

We can all help stop the spread of invasive plants by not planting them in our landscapes and by replacing existing invasives with native plant species. This fact sheet focuses on invasive plants that cause ecological harm to New Jersey's natural areas and native alternatives for landscaping and gardening. Provides lists of invasive plant species and suggested native alternatives.
