Habitat

Frogbit is typically found in ponds and slow-moving waters, showing preference for protected the protected banks. It is not well adapted to nutrient poor environments, or freezing underwater temperatures, as one of its reproductive processes is temperature sensitive. 

Life Cycle

Frogbit is a perennial plant. It germinates in mid-spring, and the leaves continue to grow and spread through late summer, when the plant flowers in June-August. In the fall, frogbit reproduces by dropping turions that sit dormant underwater through the winter. Come spring, these are the main reproductive means of frogbit. Frogbit is also capable of sexual reproduction, but it is diecious, and plant masses tend to be single sexed. 

Ecological Threat

Frogbit can outcompete native aquatic species, spreading to form large, dense mats. This reduces plant and animal diversity where frogbit is present, as frogbit is less able to support native aquatic animals than the suite of plants it replaces. Frogbit also impacts human activities. It can impede swimming and boating activities, and has been linked to agricultural decline, when mats interfere with irrigation channels.
