University of Arkansas. Cooperative Extension Service.

The collection of digital images is provided as a service to Arkansas agriculture. These images represent symptoms of both pathological (infectious) and non-pathological (physiological/environmental) disorders of agronomic row crops and horticultural crops that grow in Arkansas. These photos are useful as an identification tool to growers of the crops listed.

National Audubon Society.

Use Audubon’s native plants database and explore the best plants for birds in your area (by zip code). Audubon's native plants database draws its plant data from the North American Plant Atlas of the Biota of North America Program (BONAP).

University of Hawaii. Tropical Agriculture and Human Resources. Integrated Pest Management Program.
Provides general information on pest hosts, distribution, damage, biology, and management in the form of pest summaries.

University of Georgia. Center for Invasive Species and Ecosystem Health.

Early Detection and Distribution Mapping System (EDDMapS), provides a more accurate picture of the distribution of invasive species. EDDMapS will allow land managers, agencies, and others to set priorities for early detection and rapid response (EDRR), as well as formulate overall invasive plant management action plans. EDDMapS provides online tools for citizens to report invasive species sightings and maps these sightings to provide distribution information by species, state, and county.

USDA. NRCS. National Plant Data Center.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. The database includes names, checklists, automated tools, identification information, species abstracts, distributional data, crop information, plant symbols, plant growth data, plant materials information, plant links, references, and other plant information. The PLANTS database contains native and naturalized plants of the PLANTS Floristic Area (PFA), which consists of North America and all additional U.S. territories and protectorates.
Note: The Invasive/Noxious Weeds data in the previous PLANTS version were outdated and not migrated to the new PLANTS version (new site launched in Spring 2021). A new PLANTS Invasive/Noxious Weeds dataset has been developed and will be deployed to PLANTS in a later release.

DOI. United States Geological Survey.

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).
