{text copied from the project page}
Western redcedar is critical to the livelihood of our forests and communities. However, many reports of dieback have been shared recently. We need YOUR help to understand why!
Help science go faster by sharing observations of healthy and unhealthy redcedar trees!
More information about this project 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.
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.
{Update 25 Feb. 2021}
We've added an optional question about the size of the tree. It will be interesting to see if there are patterns between the size of the tree, the site conditions and the symptoms.
Note that we're available to give presentations or workshops to provide an introduction or update about this project and our concerns around western redcedar. Contact us if you would like to organize something for your community. We're also hosting monthly 'office hours' about using iNaturalist. You can register at https://foresthealth.org/office-hours/ .
