Virginia Department of Forestry

Virginia Department of Forestry has resources including books and fact sheets you can find by visiting Publications and Reports.  One helpful identification guide is the Department of Forestry's Tree Identification. To purchase identification books, visit Buy an Identification Book.

vTree

Virginia Tech has developed the vTree app that can narrow the list of potential tree or shrub species based on your GPS location and simple questions about the tree or shrub.  The app can be downloaded for free on your mobile device and is available for both Android and iPhone.

You can also use the ID Keys at Virginia Tech Dendrology. The webpage includes a review of the basics of tree identification and several options (leaf key, twig key, or interview) for figuring out an unknown tree or shrub.
