Invasive alien species are plants, animals, or other organisms that are introduced to a given area outside their original range and cause harm in their new home. Because they have no natural enemies to limit their reproduction, they usually spread rampantly. This forces them to drain the existing wetland and route water around the area. The hyacinth covers ponds, lakes, and bayous by forming a heavy dense cover that will block sunlight. In its native lands, this species is held in check by predators and other factors, but once introduced into North American habitats, it reproduces and spreads at an alarming rate.

The longer an invasive species survives, the more expensive and more unlikely it is for parks to successfully remove that species. This invasive species, also known as common reed, is particularly harmful because it forms monocultures that outcompete native plant communities, diminishing quality of habitat for animal species, leaving nothing but dense tall reeds which grow 5-15 feet high. These and other vernal pool types of wetlands are formed in areas with unusual topography and soil layering, and are very difficult to replace when ground is leveled for development. When exposed to high temperatures, the resulting hatchlings are rarely strong swimmers. The Invasive Species Program has identified numerous actual and potential invasive species from which we strive to protect California’s wildlands and waterways. Conservation initiatives that work at a landscape scale to address natural resource concerns, including invasive species; 3. Laurentian Great Lakes coastal wetlands are ideal systems for testing invasive species management effects because they support diverse biological communities, provide numerous ecosystem services, and are increasingly dominated by invasive macrophytes. Feral animals are known for their destructive impact on wetland areas, and can disrupt the intricate food chains that exist within the ecosystem.

Some wetlands are forested habitats, while others are largely devoid of trees. The loss of these native species disrupts the entire ecosystem by depleting the food sources of animals that depend on these animals. 13 Wetlands provide critical habitat for wildlife.

Invasive species are plant or animal species that are not native to their current location and cause severe damage to ecosystems. 2002). Invasive species may wipe out native populations by predation (eating native species), competition for resources (shelter and food), or even through spreading non-native parasites. Advised conservation groups in efforts to eradicate invasive animal species (pigs and rats) from islands in the Channel Islands and Aleutian Islands, respectively. It occurs in every continent on the earth except Antarctica. The spread of invasive species into wetlands reduces local biodiversity and may also impair the functions and values of infested wetlands.
