Demography of questionnaire respondents.

For all categorical characteristics except gender, there was a bay effect (χ2 > 7.8, df = 2, P < 0.02; Table 1: Q20-22) and different superscript letters within a row indicate differences between bays (χ2 > 4.3, df = 1, P < 0.05). For gender, the asterisk indicates that the aggregate statistic differed from expectation (χ2 > 16.4, df = 1, P < 0.001; Table 1: Q24). For age and visitation rate there was a bay effect (H > 28.0, n > 326, P < 0.001; Table 1: Q18, 23) and different superscript letters within a row indicate differences between bays (|Z| > 4.0 and P < 0.001).
