The American Tree Farm System® (ATFS), a program of the American Forest Foundation's Center for Family Forests, is committed to sustaining forests, watershed and healthy habitats through the power of private stewardship.

Established as a state agency in 1924, the mission of the Alabama Forestry Commission is three-fold: to Protect the Forests from all harmful agents; to Service and Help Landowners to carry out responsible forest management on their property, using professional technical assistance so as to benefit themselves, their land and society; and to Educate the General Public about the value of our forests in insuring both a healthy economy and environment. We do this in the most efficient and cost effective way possible.

FNA presents for the first time, in one published reference source, information on the names, taxonomic relationships, continent-wide distributions, and morphological characteristics of all plants native and naturalized found in North America north of Mexico.

The Forest History Society is a nonprofit library and archive dedicated to collecting, preserving, and disseminating forest and conservation history for all to use. The Society links the past to the future while reminding us about our important forest heritage.

In GRIN Taxonomy for Plants all families and genera of vascular plants and over 40,000 species from throughout the world are represented, especially economic plants and their relatives. Information on scientific and common names, classification, distribution, references, and economic impacts are provided.

The 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, plant links, references, crop information, and automated tools.
