After publication of Freitag, A., Meyer, R. & Whiteman, L., (2016) it was brought to light that a small number of data errors and definitions were incorrect or required clarity. These errors do not compromise the central purpose and conclusions of the paper, with all other content remaining valid. The authors take responsibility for the occurrence of the errors. Details of the required corrections are below, along with the relevant page number of the original publication.
Errors were present within the original Table 1 (p. 4–5) concerning the “Beach Watch” data (row 1) and the resulting “% employing strategy” (bottom row). The corrected Table 1 is presented below.
Table 1
Summary of credibility-building strategies and related context of 30 citizen science groups working in the Central Coast of California. Symbols in each column are explained in detail in the text, but each activity column was either Y/N for yes or no regarding whether the activity exists within the project or H/M/L/N for high/medium/low/no indicating the level of the activity. Each context column is Y/N for yes or no in answer to the question, S/M/L for small/medium/large depicting the size of a program component, or G/I for group or individual activity.

Two of the “credibility strategy” definitions (p. 6–7) required minor edits to provide clarification. The corrected text is given below.
