| Comments | I have fished in this area and at other locations within Cypress Creek for over 10 years and this is the first occurrence of this species that I have noted. I did not take a photograph, since I was wading in the creek and did not wish to risk getting my camera wet. This infestation was dense and lush, occupying approximately 80 square feet and growing in an area approximately 2.5 feet deep. I am a retired biologist and have carried out numerous exotic plant surveys. in conjunction with my employment with the U.S. Fish and Wildlife Service (USFWS) and in the private consulting field. I taught a course in aquatic plant identification in a course for USFWS biologists. I am submitting a second report for an observation in Cypress Creek upstream from this one. |
