679 Tree Species  X  33,144 Zip Codes  X  42 Pests

The Pest by Zip Code tool runs on a custom made database and app engine that maps all tree species in the US by zip code. The top 42 tree pests identified by the US Forest Service were prioritized by area and the top 3 are presented to the user when a zip code is entered in the tool.

The map to the left shows tree species richness by zip code. Richness was calculated by overlaying tree species species range maps from the US Geological Survey onto the zip code tabulation area map from the US Census Bureau. Federal lands such as military bases and national parks are not included in the zip code dataset.

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 has the following capabilities

  • Automatic detection of location from the picture’s metadata
  • Ability for the user to enter information about the tree
  • Validate Tree Tag based on data quality requirements
  • Send a confirmation to the user when a valid Tree Tag is received
  • Assign the user credit, even if they didn’t 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

Tag Using Email

Simply send an email to: with the tree pictures attached to the email. Make sure location data is saved in your pictures. See below to make sure that feature is enabled on your smart phone.

To allow your iPhone or iPad to save location data in photos:
  1. Open up the Settings app.
  2. Navigate to Privacy > Location Services.
  3. You’ll see a list of apps. Tap on Camera and then select ‘While using app’

To allow your Android phone to save location data in photos:

  1. This feature is usually enabled by default. You don’t have to make any changes
  2. If your emailed tree tags do not show up on the map, then the location data is likely not saved in photos.
  3. Each Android phone is different. We suggest searching the web for the name of your phone, like “Samsung Galaxy s8” + “enable photo geotag”

Tree Pest by Zip Code & Tagging Education Modules

The objectives of these education modules are to get students to Learn, Look, and Do:

  1. Introduce how to use the zip code pest tool and TreeTaggr - Learn
  2. Help students identify trees and diseases - Look
  3. Actively use technologies to interact with their environment - Do

Below are examples of 3 modules that make it easy for educators to modify for their specific educational needs in technology, ecology, and earth science education.

  • Early Education: Tree Identification.
    1. Mr. Jones has an elementary level class with access to student ipads that has a tree identification unit in the curriculum. He gives a homework assignment for each student to lookup trees affected by pests with the zipcode pest tool. Then to locate and take three pictures of a single tree: one of its bark, one of its leaves or needles, and one of the tree’s shape.
    2. Students send the pictures to the TreeTaaggr system to be mapped online. Mr. Jones can flag for deletion a few tags Students made on accident, checks for anything inappropriate, notes that Student-B did a great job on the assignment, notes that Student-C did a poor job on theirs, and organizes the submitted assignments based on the classes next teaching objective: Differentiating Deciduous vs Coniferous trees.
    3. In class, he displays the TreeTaggr map showing the geolocated tags his students made. He discusses the various trees, pests and has a discussions about how technology can help people 'crowdsource' information and knowledge sharing.
  • Middle/High School Biology: Seasonal Tree Changes.
    1. Mrs. Smith has a biology class that lasts from fall through the spring. Early in the class, she tells students about the zip code pest tool and TreeTaggr, and assigns each to select a single tree that they will track all year - preferably an at-risk tree species. She instructs them to identify the tree and to take a series of images of it - including one image from a specific vantage point that the student will use for future images.
    2. In class, she asks each student to present their tree. They find the tree on the map, select it, show the pictures, and discuss the tree and its surroundings. She instructs students to re-tag their tree 2x a month from the same vantage point, and to tag any details they see change over time.
    3. The class periodically checks in on the project, and when seasonal changes are observable in the images, Mrs. Smith uses the student’s tags as teaching examples. She advises students on what they should be looking for next.
    4. At the end of the year, each tree can be examined to see how it changed over the study period. She selects a few trees that exhibited significant changes over the period, possibly from pests or disease, and discusses the more subtle ways that seasons affect the environment and the active species within it. For a final project, she assigns each student to analyze their tree’s changes over the study period and to write a paper on their discoveries.
  • Advanced Research: Ecologic Conditions Impacting Tree Growth.
    1. In an advanced high school ecology class or in an undergraduate ecology class, an instructor gives an assignment to study a species of tree that grows in different environmental conditions. Students are assigned a local species of tree, and are instructed to use the TreeTaggr system to tag three different examples of their tree species: one in a more urban environment (with nearby pavement), one in a suburban environment (used as ornamentation or near manicured areas, and one in a natural forest environment.
      1. Students hunt down their assigned species and find excellent examples of adult trees in the specified environments. They tag the trees at each location and include specific data on each:
        #species= (the assigned species)
        #sex= (male/female/both)
        #dbh= (diameter at breast-height)
        #setting= (urban/suburban/rural)
        #health= (notes about observable health)
        #cankers= (history of infection/pest)
        #pests= (any noticeable pests present)
        #biodiversity= (any symbiotic or parasitic relationships noticed)
    2. The instructor uses the supplied data in class lecture, and tasks students with repeating the assignment and finding another set of examples of the species growing in different environments.
    3. To complete the project, each student writes an analysis of the immediate environment’s impact on the tree species and to draw any conclusions based on their collected data. The best analyses are chosen by the instructor and are published to the public system with a special #research notation. Scientists can search for and use this data that was collected by the students to aid in their active areas of research.
