*note: A higher index value indicates higher biodiversity.
Smaller sample sizes are less accurate. When comparing index values consider the number sampled and sample area.
Schools with at least one plot size of zero will have infinity as their average number of trees per acre. Average plot size is also incorrect for the same reason.

Following is the source data.
