North America is graced with an amazing array of native plants in a wide range of habitats from boreal forests, alpine tundra, and prairie grasslands to interior deserts, coastal salt marshes, and tropical rainforests. About 17,000 species of vascular plants (among them many that are traditionally defined as herbs for their medicinal, cosmetic, and culinary uses) are native to one or more states.
Many of these natives are threatened by an accumulation of factors related to population growth and the spread of development, browsing or trampling by domestic or feral animals, competition from aggressive, non-native plants, and over-collection of those plants with commercial and medicinal value. Conserving the biodiversity and health of native plants and ecosystems is essential to a healthy planet. FIND OUT MORE
