Description
Relationship between aquatic macrophyte composition and environmental factors were studied in 149 irrigation ponds mostly distributed in the surrounding area of Lake Shinji, Shimane Prefecture, Japan, during the summer of 1984, 1986 and 1988. During the study, a total of 38 taxa were recorded, and 17 environmental factors such as altitude, depth, transparency, pH, electric conductivity, COD, alkalinity, chlorophyll a, ignition loss of bottom soil, Na, K, Ca, Mg, Mn, Fe, P0_4-P and total P contents were measured. Since the results processed by statistical treatment and/or multivariate analysis have already been published, the raw data on macrophyte composition and environmental factors are presented in this paper as appendices, expecting the information to be of general use.
