Vegetation & Plant Identification

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.

Aquatic plants are generally divided into four groups for management purposes. These groups are:

Algae and Plankton

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).
Floating Plants

Floating Plants

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.
