Here you will find files related to citizen science research at GBIF.
You can get a json list of all citizen science datasets using:
http://api.gbif.org/v1/dataset?machineTagNamespace=citizenScience.mgrosjean.gbif.org&limit=500
One can get a table of citizen science counts using R. Requires my gbifapi package.
