The Purdue Tree Doctor app can help you identify and manage problems on trees. Using the app, you can match damaged plant parts with over 1,000 high resolution photos. Further check your visual diagnoses by following links on each photo to detailed descriptions of damage and stages of problem development. Search for information by tree or pest and get recommendations on how to manage more than 175 problems on 60+ kinds of trees. The app focuses on the most common problems of trees in the Midwestern and Eastern United States.
This app was developed by Purdue University experts to help people better identify and manage common tree problems. This app should help improve communication between landscape professionals and their customers. See sample screen shots (PDF).

Biomass Calculator is a tool that can be used for estimating woodlands as attention increases on wood-based bioenergy for fuel. It is an extension of the Forest Inventory 2000 application, which was originally developed by Terence E. Hanley and Don Carlson, Indiana Department of Natural Resources, Division of Forestry, from a program by Dr. John W. Moser, Jr., Purdue University, Department of Forestry and Natural Resources (May 2000). The extension to estimate biomass and carbon content according to U.S.D.A. FIA procedures was developed by Justin Arseneault, Purdue University, Department of Forestry and Natural Resources (May 2014). Project was sponsored by SunGrant Initiative.
