The main goal of this project is to develop smartphone app to correctly identified tree speciesby their bark for hardwood trees in the Central Hardwood region. Specific objectives are:

  • Develop a standard protocol for data collection.
  • Develop a smartphone app that will allow users to acquire images of tree bark and associated data in the field, and transmit this data to a central database.
  • Develop a central database that will house the collected information, allow for verification and data labeling, query, and sharing among researchers.
  • Develop Bark ID app
  • Organize workshops to train professionals and the public on using the bark ID app. Additionally, organize an international workshop for researchers working on AI approaches to tree bark identification.
