I took a jaunt up on Co Rt 20 to check the status of the U. macrorhiza that grows there. Happily, I found the plants in flower, the first flowers just now evident. You can never find it until the beautiful large yellow flowers appear. It is a happy population, growing in fairly shallow water in association with algae and duck weed and other aquatic species. The area sports a very healthy population of frogs, always a good indicator of a pristine habitat. This population looks like it is here to stay as the wetland stretches for miles, and the plants are all through it.
Just wanted to share the good tidings!
