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.

DOI. USGS. ScienceBase Catalog.
USGS has published, and plans to update on a bimonthly basis into the foreseeable future, a dataset called "Catalog of U.S. Federal Early Detection/Rapid Response Invasive Species Databases and Tools." The catalog, developed in collaboration with the National Invasive Species Council Secretariat, is a multi-sheet spreadsheet that contains openly available, online, federally supported databases and tools dealing with various aspects of a potential national early detection and rapid response invasive species framework.

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.
Global Biodiversity Information Facility.
The Global Biodiversity Information Facility (GBIF) is an international network and data infrastructure funded by the world's governments and aimed at providing anyone, anywhere, open access to data about all types of life on Earth.
Provides mapping functions for species globally. The GBIF network draws sources together through the use of data standards, such as Darwin Core, which forms the basis for the bulk of GBIF.org's index of hundreds of millions of species occurrence records. Publishers provide open access to their datasets using machine-readable Creative Commons license designations, allowing scientists, researchers, and others to apply the data in hundreds of peer-reviewed publications and policy papers each year. Many of these analyses—which cover topics from the impacts of climate change and the spread of invasive and alien pests to priorities for conservation and protected areas, food security and human health— would not be possible without this.
IUCN. Species Survival Commission. Invasive Species Specialist Group.
The Global Invasive Species Database aims to increase awareness about invasive alien species and to facilitate effective prevention and management activities. The database focuses on invasive alien species that threaten native biodiversity and covers all taxonomic groups from micro-organisms to animals and plants in all ecosystems. Species information is either supplied by or reviewed by expert contributors from around the world. Provides distribution, life history, and impacts data for invasive species.

Brock University (Canada).
The Niagara Region’s Aquatic and Riparian Invasive Species Control Database (created by Lyn A. Brown as part of a Master of Sustainability thesis at Brock University) provides a baseline for the 2017/18 state of aquatic and riparian invasive management activities in the Niagara Region of Ontario. An interactive GIS map uses the database information to show where those control efforts are occurring, and users can filter points on the map by invasive species, control type, control effectiveness, or organization.
