Virginia Tech Tree Identification brings the award winning Virginia Tech digital dendrology material to your iPhone. It contains fact sheets for 969 woody plants from all over North America with an in-depth description, range map and thousands of color images of leaves, flowers, fruit, twigs, bark and form.
Users can narrow the species list for any location in North America using the phone's GPS or any entered address or zip code. Basically the application can become "The Woody Plants of Where You Are Standing." For example, it can become "The Woody Plants of Southwestern Oregon," "The Woody Plants of Central Park," or "The Woody Plants of 37.108 lat., -80.452 long., elevation 2118."
Users can further narrow the species list by answering a series of very simple tree attribute questions such as where the plant is growing, leaf shape, leaf arrangement, flower color or fruit type. The species list can also be narrowed by typing a keyword such as oak, Abies, red or palm. For example, if "oak" is typed, only oaks found in the defined area will be listed.
A feature also allows you to send any tree related question to "Dr. Dendro," a tree expert in the Department of Forest Resources and Environmental Conservation at Virginia Tech. You can send a tree description or pictures of your plant and experts will help with identification.
