iNaturalist monitoring & mapping
Decentralizing a tree survey like this empowers everyone to collectively contribute data with the intent of understanding how this species is tolerating myriad diseases and to identify healthy tree populations. Surveyors using the app pinpoint tree location and health on the map, so data from British Columbia to Southern Californica will ultimately help inform us about the true range of the species along our shared Western Coast. You too can be our “eyes-in-the-field.” Anyone can virtually tag or snap these trees using iNaturalist. All you need is to download the free app on your mobile device and a basic knowledge of how to identify Pacific madrone.
You walk through your neighborhood and park and spot a madrone. Bingo.
Open the app and snap a photo. Location services on your phone pinpoints the location of the tree. The approximate spot will later show up on the iNaturalist projects.
Answer questions about the height and diameter of the tree
Do you find this tree standing alone by itself or in a forest? Answer a question about that.
Give your opinion about the health of the tree’s canopy
Note any disease symptoms on the leaves, branches and trunk(s)
Leave a few comments if you wish. Boom, done in less than five minutes.

Click the map on the left to access Pacific madrone distribution data on TreeSnap. This was our original mapping system. The health of Pacific madrone trees submitted in TreeSnap have been highly variable. This variation is interesting, but more observations are needed to see if any patterns emerge. We are also looking at the health of the trees in relation to the symptoms that are reported.
TreeSnap got its start in 2017, funded in part by the National Science Foundation Plant Genome Research Program. People have been using this app to track Midwest tree diseases and pests, like dutch elm disease and emerald ash borer. And Pacific madrone was the first West Coast tree added to the app in late 2018. Data collected can be applied to real research - we are interested in health and range of madrones.
“We are excited to have our first native tree from the western part of the United States included in TreeSnap, making this a truly national effort. With so many new species and passionate conservation groups, we enjoy watching the leaderboard on the home page, where everyone can see who is reporting the most trees. This competition aspect really helps to motivate people to get out in nature and see the trees around them.”
