WSU Puyallup Pacific Madrone Survey

We are creating a database to update the madrone distribution map and learn more about the health condition of the species throughout its range.

For details about the data and representative photos to help you complete the survey, download the Pacific Madrone Assessment Guidebook, then complete the survey using one of the methods below.


We are primarily collecting data using the TreeSnap smartphone app. However, two other methods to contribute are listed below.


TreeSnap is a smartphone app. Data can be uploaded later if internet connection not available in the field. Visit the Arbutus ARME webpage for more information about using the app.

Instructions: Youtube video on how to use TreeSnap (~5 minutes).
