| Abstract: | During 1993-94 and 1994-95, the amount of watershield (Brasenia schreberi) in selected Maryland wetlands was determined to see if a relationship existed between the amount of watershield on a wetland and the number of ring-necked ducks (Aythya collaris) observed on that wetland. Data were collected for two years from eight different wetlands on the Patuxent Research Refuge in Laurel, Maryland. Results indicate there was no significant correlation between the amount of watershield in a wetland and the number of ring-necked ducks observed on that wetland. |
