A database that couples phytoremediation technology to plant species information is being developed through a cooperative effort with the USDA-NRCS National Plant Data Center and Kansas State University's Great Plains/Rocky Mountain Hazardous Substance Research Center.  This database links plant science with environmental technology to assist conservationists, landowners, land managers, and revegetation specialists in remediation and rehabilitation of lands damaged from a variety of contaminants (e.g. heavy metals, pesticides, hydrocarbon, organics, and nutrients). Published research pilot studies and direct field applications using phytoremediation technology forms the foundation of the database. The database is searchable by: contaminant group (e.g. heavy metal, nutrients), specific contaminant (e.g. lead, selenium), planting media (e.g. soil, wetland), field application readiness as defined as 1 to 7 with 7 as most ready, phytoremediation mechanism (e.g. phytodegradation, phytoaccumulation), study type (e.g. greenhouse, field) and plant species (e.g. Latin or common name). For plant species information the database is linked to the PLANTS profiles in the USDA-NRCS PLANTS data base (http://plants.usda.gov/). The PLANTS profiles provide the user with information on plant characteristics, classification, planting guides, images, and species distribution, along with other plant related information. Other plant science information to augment the phytoremediation database are the USDA-NRCS National Plant Materials Program (http://plant-materials.nrcs.usda.gov/) and the USDA-NRCS Field Office Technical Guide (http://www.nrcs.usda.gov/Technical/efotg/).  These technical resources offer the user a comprehensive assessment of the best adapted cultivars and varieties of grasses, legumes and woody plants for specific regions of the U.S. Also provided is a listing of technical specialists who have knowledge and experience in establishment and management requirements, commercial sources of seed and plants, and technical publications for land rehabilitation.
