Redcedar | Data | Analyses | Instructions |
The purpose of this page is to provide a dataset to use in subsequent analyses. Major changes to original data will be documented here and a final dataset will be exported here.
Observation data were downloaded from the Wester Redcedar Dieback Map project on January 13, 2024 after 2600+ observations were shared.
The query used to download data is as follows “quality_grade=any&identifications=any&projects%5B%5D=western-redcedar-dieback-map”. All ‘Geo’ columns and ‘Observation Fields’ columns were included.
Some of the iNat project questions changed since it was created so some we need to adjust the answers to be more consistent throughout the project.
