Ecology: Plants

The Native Plant Database is a tool to support urban greenspace stewardship and restoration across Canada.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories and Canada. It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, crop information, automated tools, onward Web links, and references. This information primarily promotes land conservation in the United States and its territories, but academic, educational, and general use is encouraged.

This website provides information on plant classification by class, order, subclass, superorder, family, tribe, genus, genera, species.

This site merges the book A Guide to Field Guides: Identifying the Natural History of North America by Diane Schmidt, Emeritus Biology Librarian at the University of Illinois, and its companion Web site International Field Guides. After the publisher returned copyright to the book, the author decided to combine the two products and create a searchable database of field guides for plants, animals, and other objects in North America and around the world.
