Abstract
Networks of citizen scientists (CS) have the potential to observe biodiversity and species distributions at
global scales. Yet the adoption of such datasets in conservation science may be hindered by a perception
that the data are of low quality. This perception likely stems from the propensity of data generated by CS
to contain greater levels of variability (e.g., measurement error) or bias (e.g., spatio-temporal clustering)
in comparison to data collected by scientists or instruments. Modern analytical approaches can account
for many types of error and bias typical of CS datasets. It is possible to (1) describe how pseudo-replication
in sampling influences the overall variability in response data using mixed-effects modeling, (2) integrate
data to explicitly model the sampling process and account for bias using a hierarchical modeling
framework, and (3) examine the relative influence of many different or related explanatory factors using
machine learning tools. Information from these modeling approaches can be used to predict species distributions
and to estimate biodiversity. Even so, achieving the full potential from CS projects requires
meta-data describing the sampling process, reference data to allow for standardization, and insightful
modeling suitable to the question of interest.
