Blog topic 10/11

Hydrilla
1.  Hydrilla is among the worst of the invasive aquatic plants and they can spread easily via fragments broken off from plants in the water. 
2.  Hydrilla can grow in any type of fresh water; the only exception is that hygrophila grows primarily in flowing water. 
3.  It can also grow in low light levels, so the plant can thrive in very little sunlight. 
4.  Since hydrilla grows quickly in a variety of conditions it can live anywhere.

Purple Loosestrife

1.  Invasion of Loosestrife into a wetland can result in the suppression of the resident plant community and the eventual alteration of the wetland's structure and function. 
2.  Large monotypic stands of Loosestrife jeopardize various threatened and endangered native wetland plants and wildlife by eliminating natural foods and cover. 
3.  Dense plant establishments in irrigation systems has impeded the flow of water.

Water Lettuce

1.  Water lettuce can have a severe impact on the environment and economy of infested areas. 2.  The dense mats created by connected rosettes of the plant lead to the majority of problems encountered with water lettuce. 
3.  These mats can have a negative economic effect by blocking waterways, thus increasing the difficulty of navigation and hindering flood control efforts. 
4.  Mats of water lettuce can also have a severe impact on the environment.
