Project Goal



The mission of OregonFlora is to serve as the primary steward of Oregon's botanical information and to guide its use and application. The information we present spans the topics shown below.

The Oregon Plant Atlas — an interactive mapping program which draws from a database of over 540,000 records to display plant distributions and the data behind each mappable point.

Photo Gallery — a collection of photographs for each plant featuring its habitat, general features, and details, as well as images of herbarium specimens.

The Rare Plant Guide — a searchable database and field-oriented fact sheets about some of Oregon's rare and threatened species.

The Vascular Plant Checklist — provides the taxonomic foundation for the complete project, listing accepted scientific names, common names, and synonyms for all Oregon vascular plants.

A Flora of Oregon — the definitive reference for plant identification, presented as a three-volume printed work and an interactive website.
