The most parsimonious (ΔAIC_c < 2) set of models, and model average, explaining variation in the Volunteer Function Inventory (VFI) ‘Values’ and ‘Understanding’ motivations for Garden Wildlife Health Systematic (n = 177) and Opportunistic (n = 218) citizen science data contributors. Parameter estimates are provided with standard errors.
