| Comments | My colleague Heather Hunter-Nichols reported the trapa to myself (Scott Baron) and a colleague, Sophia Wood after Heather's July 13, 2023 visit. It is difficult to determine the percent cover of the trapa in the pond from the photo because of the abundant watermeal or duckweed. It may be at least 50 percent. |
