The main premise behind the control of exotic and invasive species is that one species out competes other native and more sensitive species for the same limited resources. Example would be Kudzu Pueraria lobataI'm a little lost on the concept of invasive plant species. The California poppy is considered invasive in many areas, it sure is a pretty flower, though. I figure all plants are native to the Earth, and it might be commendable for some to have an impressive range, which ensures their long term survival.
Some exotics are domesticated and useful like corn and oats but do not pose a threat to local ecosystems. A noxious plant is a legal designation to a species that has been determined to be a major pest of agriculture ecosystems.From the National Park Service:
An invasive species is one that displays rapid growth and spread, allowing it to establish over large areas. Free from the vast and complex array of natural controls present in their native lands, including herbivores, parasites, and diseases, exotic plants may experience rapid and unrestricted growth in new environments. Invasiveness is enhanced by features such as strong vegetative growth, abundant seed production, high seed germination rate, long-lived seeds, and rapid maturation to a sexually reproductive (seed-producing) stage.
Some of the known ecological impacts of invasive plants are summarized below, and include:
•reduction of biodiversity
•loss of and encroachment upon endangered and threatened species and their habitat
•loss of habitat for native insects, birds, and other wildlife
•loss of food sources for wildlife
•changes to natural ecological processes such as plant community succession
•alterations to the frequency and intensity of natural fires
•disruption of native plant-animal associations such as pollination, seed dispersal and host-plant relationships
I would say no. It would be natural selection and succession. Often we have an idea of an ecosystem as being a static environment with little change over hundreds sometimes thousands of years. We are mistaken. The environment is dynamic and always changing. With the mobility of humans and migratory animals it is speeding up the dominate takeover of a few well adapted species. It can only be described as Gods will for the planet.The one question that remains.... aren't We an invasive species?
With his expedition on the H. M. S. Beagle, C. Drawin pointed out thatIn conclusion wash your rigs if you want.It is the preservation of a functional advantage that enables a species to compete better in the wild, and acts only by taking advantage of slight successive variations and species diversity is a result of geographic isolation.
