Want to collect more data or set up permanent plots?
Our partners in federal and state agencies have developed a more robust tool on Survey123 to measure stands of western redcedar and collect samples. Please contact Christine Buhl (OR), Betsy Goodrich (WA), or Melissa Fischer (WA) for more information.
Help science go faster! All observation data collected in the iNaturalist project are open and available to anyone.
Although the data is open, we request that researchers contact us if they are interested in using the data.
Observation data will be used to identify patterns in the distribution of the western redcedar decline.
Common Site Characteristics
Relationship with Climate
Overlay analysis will be completed to evaluate the relationship between historical climate data and patterns of decline.
