Western Redcedar Dieback Map

Western redcedar is critical to the livelihood of our forests and communities. However, many reports of dieback have been shared recently. We urgently need YOUR help to understand why!

Help science go faster by sharing observations of healthy and unhealthy redcedar trees!

Instructions for specifically contributing to this project are available at https://foresthealth.org/map

Together we can identify vulnerable areas by discovering patterns across landscapes. Help advance knowledge about the factors and drivers killing western redcedar trees by sharing your observations.

Please add one observation for each tree. Alternatively, you can indicate if multiple unhealthy trees are present, but please only refer to the single tree in the first image when answering the questions.

Please include a images of the whole tree, the trunk (including the bark), and the cones if present. These images will help distinguish the observation from other similar looking cedars.
If the cones are not present, please take a close up of the bloom (white powder) on the underside of the leaves.
