Trees, Shrubs and Vines of North America - eTreesNA - A Tree App

eTreesNA - Trees, Shrubs and Vines of North America - A Tree App is a member of the World Life Forms family of products designed to provide easy to use, powerful tools for accessing images and information of the world's diverse life forms.

With over 700 life forms (see counts by taxonomic order below), eTreesNA can serve as a reference tool for botanists, educators and students. The life forms are accessible by common name, latin name and taxonomy.

Each life form is presented with a summary profile, an image, a textual description, and it's taxonomy tree. Maps are also included for many of the life forms.

A free sampler, eLifeFormsW - A Search Life Forms Sampler is available for free download and review. We strongly recommend all interested customers download and sample the demonstration version before buying our paid for products. This "try before you buy" policy allows for interacting with the user interface, content sampling and overall review of the presentation. As regular users of wild life reference materials, we believe our products are best positioned as a supplement to the field guides, software identification tools, atlases and other animal and plant life compendiums and not a replacement.
