Below are links to some of the tools currently available to those working on vegetation classification:
VegBank is the vegetation plot database of the Ecological Society of America’s Panel on Vegetation Classification. VegBank consists of three linked databases that contain (1) the actual plot records, (2) vegetation types recognized in the U.S. National Vegetation Classification and other vegetation types submitted by users, and (3) all plant taxa recognized by ITIS/USDA as well as all other plant taxa recorded in plot records.
The USNVC Hierarchy Browser provides detailed descriptions of all U.S. vegetation, with ecological context and geographic ranges. Types and descriptions are drafts and in peer review, and this tool is still under development.
The USDA PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, crop information, automated tools, onward Web links, and references.
The NatureServe Explorer is an authoritative source for information on more than 70,000 plants, animals, and ecosystems of the United States and Canada. Explorer includes particularly in-depth coverage for rare and endangered species.
