Table 1:

Wilcoxon median rank sum test results for comparisons of total bat activity, species specific bat activity, diversity indices, and species richness between the control and proposed wetland/wetland sites before the wetland construction (November 19th, 2016 – March 14th, 2017) and after the wetland construction (March 15th, 2017 – March 28th, 2018). For pre-construction control vs proposed wetland bat activity comparisons n = 177, diversity indices and species richness comparisons n = 17. For post-construction control vs wetland bat activity comparisons n = 692, diversity indices and species richness comparisons n = 55. Significant p-values are in bold.
