Table 7. Proportions of common species at sites without and with integrated or adjacent agricultural activities.
Proportions of six common species within combined samples at sites without (0) and with (1) integrated or adjacent agricultural activities (2016–2017 survey period). Chi-square contingency table comparisons for each species are between sites with 0 and 1 index values, comparing numbers for each species listed in table with all other species combined. d.f. = 1 for all tests.
