Top Quad Needs – Urbana (39077_C3)

This page displays the top 100 taxa not recorded in this quad, but recorded in the highest number of quads in the atlas (not weighted by neighboring quads). Filtering by number of quads removes biases toward rare species with many records from close monitoring. To prioritize species with high detectability, specimens are excluded from the filtered result set. There are 260 quads. View USGS Quad Map.
