This free app for the iPhone provides a highly portable and easy-to-use tool for identifying Wisconsin trees, shrubs and vines. It is super-convenient for field biologists, since once installed, this "native" app does not require a cell-phone signal to function!
The key includes 85 species of trees and 57 species of shrubs and vines that are native to Wisconsin's woodlands or exotic and invasive. The key does not include forbs and shrubs of prairies, bogs and other open habitats, nor herbaceous plants. A few difficult-to-identify groups (Crataegus, Ribes and Salix) are only keyed to genus.
The tool is structured like a typical dichotomous key, allowing the user to select among two choices until arriving at the correct species. Each species is illustrated with detailed photos, ecological information and distribution maps. Other features include a built in glossary with definitions of the small number of technical terms that are used in the key, and browsable lists by common or scientific name.
This app was created in 2011 by Dr. Catherine Woodward and was made possible by a grant from the Wisconsin Environmental Education Board.
