Aquatic plants are generally divided into four groups for management purposes. These groups
Many ponds have more than one type of aquatic plant, and care must be taken to identify all the
aquatic plants inhabiting the pond. Some pond plants may be beneficial to local or migratory
wildlife, and therefore, may want to be encouraged or at least not eliminated.
Algae and Other Plankton
Algae are very primitive plants. Some algae are microscopic (planktonic algae). Others are thin and stringy or hair-like (filamentous algae). While still others are large and resemble higher plants but without true roots (chara).
True floating plants are not attached to the bottom. Floating plants come in sizes from very small
(duckweed) to over a foot in diameter (water hyacinth). Most, but not all, have roots that hang in
the water from the floating green portions.
Submerged plants are rooted plants with most of their vegetative mass below the water surface,
although some portions may stick above the water. One discerning characteristic of submerged
plants is their flaccid or soft stems, which is why they do not usually rise above the water’s
