Instructional Ideas

  • Bring a variety of leaves into class and let learners use the app to identify what tree they came from
  • Assign each student a different tree to research and use the app as a first-stop place for gathering information 
Classroom Considerations

  • Requires WiFi or 3G, which would make it useless if in remote areas
  • In order to identify an unknown leaf, it must be photographed on a white background. So, if you are taking your class outdoors, make sure to bring some white paper with you.
Pros

  • Beautiful, high-resolution images contribute to easier plant identification
  • Easy to navigate
Cons

  • Does not include tree crown shapes, which would give more confidence to amateur nomenclators
  • Originally designed with a focus on Northwest American trees, with a promise to add more; as of the date of this review, it does not appear that content has been updated
  • Crashes when playing identification games
  • Unable to figure out how to label photographed leaves once they are identified
