Non-native Species Removal
California Department of Boating and Waterways' Aquatic Pest Control Program has since 1982 targeted to control water hyacinth from state waters. A native of the Amazon River in South America, the water hyacinth was introduced to the Sacramento-San Joaquin River Delta in the early 20th century. Due to the quick blooming of the water hyacinth, the plant displaces native wildlife, blocks light needed for photosynthesis, reduces the amount of dissolved oxygen in the water, and deposits silt and organic matter at several times the normal rate. In 1997, the department added the egeria densa, another South American native, onto its list of species targeted for control and eradication.
Famous quotes containing the words removal and/or species:
“Many a reformer perishes in his removal of rubbish,and that makes the offensiveness of the class. They are partial; they are not equal to the work they pretend. They lose their way; in the assault on the kingdom of darkness, they expend all their energy on some accidental evil, and lose their sanity and power of benefit.”
—Ralph Waldo Emerson (18031882)
“An unjust law is itself a species of violence. Arrest for its breach is more so.”
—Mohandas K. Gandhi (18691948)
