Aquatic Plant Information System

APIS logo-composite of plant photos with letters APIS

Developed by the Army Corps of Engineers Aquatic Plant Control Research Program, the Aquatic Plant Information System is designed to help managers access pertinent and up-to-date information on ecology, biology, systematics, identification, and environmentally compatible management techniques.

Habitattitude Campaign

A campaign geared towards aquarium hobbyists, backyard pond owners, water gardeners and others.  Habitattitude TM is about consumer awareness and responsible behaviors. By drawing attention to the potential environmental ramifications of the aquarium and water garden hobbies while promoting responsible consumer behaviors, Habitattitude TM avoids the definition debate surrounding "invasive species." Ultimately, the campaign seeks to eliminate the transfer and survival of any species outside of your enclosed, artificial system, which has the potential to cause the loss or decline of native plants and animals.

Protect Your Waters and Stop Aquatic Hitchhikers


 The Stop Aquatic Hitchhikers! campaign and Protect Your Waters web site empower recreational users to become part of the solution in stopping the transport and spread of these harmful hitchhikers.

The national Aquatic Nuisance Species (ANS) Task Force, the U.S. Fish and Wildlife Service and the U.S. Coast Guard are the primary sponsors of this campaign.

 This site provides information about aquatic hitchhikers, how to prevent them and recent news stories.

Species Spotlight


Water hyacinth
Eichhornia crassipes

Description: Floating plants with spongy leaf stalk. Flowers are purple. Leaves are shiny and oval on bulbous stalks. Often form dense mats.

Life History: This is probably the most aggressive aquatic weed ever known in the tropics. It reproduces both vegetatively and sexually.

Habitat: Lakes, streams, ponds, waterways, ditches, and backwater areas.

Distribution: Water hyacinth originated in tropical South America. (MAP)

Water lettuce
Pistia stratiotes

Description: This species resembles a "blooming" floating head of cabbage. It has long, feathery, hanging roots.

Life History: Reproduces both vegetatively and by seed. Vegetative reproduction involves daughter vegetative offshoots of mother plants.

Distribution: Probably native to South America. It is now found throughout the tropics and subtropics. (MAP)

Hydrilla; Waterthyme
Hydrilla verticillata

Description: Four to eight thin, whorled leaves around a stem. Closely resembles other members of this family such as Elodea canadensis (native to North America) and Egeria densa (native to South America).

Life History: Growth and spread often are rapid. This species often reproduces vegetatively from stem fragments. Hydrilla can be either monoecious (both male and female flowers on the same plant) or dioecious (male and female flowers on different plants). Each variety of hydrilla has some unique growth characteristics. Southern populations are predominantly dioecious female (plants having only female flowers) that overwinter as perennials. Populations north of South Carolina are essentially monoecious (having both male and female flowers on the same plant). They set some fertile seed, and depend on tubers for overwintering.

Habitat: Freshwater lakes, ponds, rivers, impoundments and canals.

Distribution: Hydrilla verticillata is widely distributed in the Eastern Hemisphere but it is uncertain as to where it is truly native.
