Data for "Twenty years (2000 - 2020) of butterfly monitoring data in the contiguous United States"

Data from an integrated butterfly monitoring dataset the United States from 2000-2020. Data span 19 butterfly monitoring programs and the integrated dataset contains over 1.2 million count records, from 65,000 surveys, representing over 12.6 million individual butterflies. Data sharing policies vary across programs so data have been anonymized as appropriate per each program's request. In addition to the integrated dataset, we share the code used to compile and clean raw data, harmonize taxonomy, and validate the final dataset. This dataset is a more granular version of the data used in the publication "Rapid butterfly declines across the United States during the 21st Century". The data for that publication is available here: https://doi.org/10.6084/m9.figshare.27934629.v1
The Code map file in the parent directory provides general descriptions of the provided code. A key note is that much of the provided code will not run because we are not sharing non-anonymized data. Some programs allow raw data to be shared, others require that latitude and longitude are rounded to obscure exact sampling locations. Similarly with site IDs some programs share siteIDs as reported in the original data, others require anonymized site IDs. The details of each program's data sharing permissions can be found in '1_raw_data.'
Despite the fact that we cannot share all raw data with this data release, we shared all the code used to assemble the original integrated dataset. A guide to the code, data, and sequence of analysis can be found in '3_scripts/clean-run.R'. If a user were to request and obtain the original data files from program directors, this script will assemble the original, integrated dataset. The one script in the directory that will run here is '3_scripts/data-figures-eh.R'; it will replicate the figure from the publication. The taxonomic dictionaries we used to harmonize taxonomy across programs can be found in '2_data_wrangling/dictionaries' and the script in which the dictionaries are used is in '3_scripts/data-cleaning-scripts/final-data-integration.R'. These dictionaries and scripts may be useful for other work harmonizing names/taxonomies.
