The TreeTaggr System

Imagine if everyone who loved trees could help gather good, reliable, forest health data. With TreeTaggr, they are able to. Smartphones have all the hardware necessary to gather pictures, location, observational details, and send it all to a central database. The TreeTaggr system was built from the ground up to not only gather and sort this data, but to foster a community of users that learn about forests while working together to create robust, actionable, forest health information.

TreeTaggr will change the way we interact with our forests.

The TreeTaggr system has the following capabilities:
  • Uses Twitter as the front-end app since it is free on every smartphone
  • Automatic detection of the user’s location when a 'Tweet' is sent
  • Ability for the user to enter information about the tree
  • Receive a photograph of the tree or pest
  • Process the 'Tweet' into a validated Tree Tag based on data quality requirements
  • Send a confirmation to the user when a valid Tree Tag is received by them, or send a message explaining why the 'Tweet' was not validated, and how to fix it
  • Assign credit to the user, even if they choose not to set up an account with TreeTaggr
  • Automatically update a global recognition board with user's rank and effort levels for comparison, competition, and other recognition opportunities
  • Store all the collected information in a highly scalable cloud database
  • Distribute the information in the open-source JSON data format

“From a certain perspective TreeTaggr is simple. It is basically a ‘crowd sourced’ data collection tool for tracking the spread of tree disease within and across forests. But TreeTaggr is also a harbinger for something much bigger. TreeTaggr portends a new way of thinking about scientific research and a new way of thinking about volunteerism.” – Neil Hepburn, PwC, Canada

Tag Like a Pro

Here are some tips for making professional quality Tree Tags

Don't forget the basics

Your Tweet must have these things in order for it to validate and be used by TreeTaggr:
  1. You must be following TreeTaggr on Twitter in order to get verification that your Tree Tag is valid and accepted by the TreeTaggr System
  2. You must have @treetaggr somewhere in the body of the tweet - preferably at the beginning
  3. There must be a GPS location in your Tweet. Make sure the arrow at the bottom of your Tweet compose screen is blue and the 'Share precise location' button is turned on for EVERY tweet.
  4. There must be a picture of a tree or a tree pest in your Tweet.
  5. You can use #species= OR #espece= (For our French Canadian friends at If you know the species then enter it. If you don't, you can enter a ? after the =

Advanced Tagging

The more information you can send the better. Consider adding some or all of these tags:
  1. #disease - Including #disease= will put more information into the database. For example, #disease=EAB (short for Emerald Ash Borer) is very helpful. If there's no disease, then #disease=none is valid
  2. #field - Add a field condition hashtag. For example, if you are in a park, #field=park would be useful to include. Or if you are in a recently burned area #field=burned is useful.
  3. Tell a friend with @ - You have to have @treetaggr in your tweet, but you can send it to other contacts as well. For example we wouldn't mind seeing your tag @AdamCostanza or @SusanHMcCord
  4. We will be adding more tags to the TreeTaggr System in the future. Join our mailing list (coming soon) to stay in the loop.

Troubleshooting TreeTaggr

Here's what to do if things aren't working properly

Check your phone

Your phone should be updated with the current software to keep it working properly with Twitter:
  1. See if there is an update for your phone by following the instructions for your phone. Here are the iPhone iOS update instructions, Android update instructions, and Windows update instructions
  2. Make sure you have the latest version of Twitter for your phone by downloading and installing the latest version here
  3. Make sure you are following TreeTaggr on Twitter. This is important so that we can send you a direct Twitter message about your tags
  4. Sending a Tweet while you are not connected to a cellular network does not work because of a bug in the Twitter app. Help us by asking Twitter developers to fix this feature. Learn more about the bug here or simply retweet our request for support here.
