Effects of Invasive Plant Species on Saltwater Tidal Marshes

What is a tidal saltwater marsh or wetland? Our book (Gosselink 2000) defines a tidal saltwater marsh as adhering to the vague but, generally established definition of a wetland plus also, experiencing periodic inundation due to the effects of tide influx caused by either the moon cycle, as do tidal saltwater marshes of California, or by wind, like the tidal saltwater marshes found here in the Gulf Coast. Tidal saltwater marshes are located around the globe and can have some very different features. All of them, mangrove marshes excluded, show a similar pattern of plant succession. These plants are similar in most marshes but, different areas posses their own distinct species. While Spartina alterniflora is a native to the Gulf Coast and to the East coast (Ayres et al. 1999) they are invasive when introduced on the West coast, which happened in the mid 1970 's where it started out competing the native Spartina foliosa (Ayres et al. 1999). Many species when carried over to another tidal saltwater marsh, whether on accident or on purpose, can become invasive and have a detrimental impact on the previously stable environment.

How invasive species take over once introduced:

The main threat of invasive plant species is the effects it will have once it displaces native plant species How are invasive plants are able to displace the native plant populations in the first place? Invading plant species are able to displace the native plant populations by various means the following avenues: hybridization, competitive edge and pathogen introduction followed by their ensuing after effects are discussed below.

Hybridization can lead to the displacement of native plan...

...icrobial taxa where lost completely then inoculation of the area with desired soil biota may be required for native plants to recolonize the area (Zubek et al. 2009).

If hand removal proves to difficult then toxic chemicals may have to be used these are costly and harmful to the native species in the area as well

Physical and chemical effects or legacies caused by invasive species can cause problems when attempting to reestablishing a native species population. There will be associated labor cost for seeding and planting of desired native species (Cione et al. 2002), augmentation of soil resources via amendment or removal (Perry et al. 2010), or perhaps even human control over natural disturbance regimes (D 'Antonio and Vitousek 1992) in order to hinder invasive intrusions or to encourage natural progression of native species.

Essay on Invasive Species And Other Biotic Factors

- The term invasive species is described as a species that is introduced into an area in which it is not native. This species has the potential to cause a negative effect to the native species and other biotic factors in those surroundings (Invasive Species, n.d). Any kind of living organism can be a potential invasive species, including the seeds and eggs of an organism (Invasive Species, n.d). These species can be brought into an area any number of ways but are usually a result of human activity (Invasive Species, n.d)....   [tags: Invasive species, Introduced species, Ecology]

An invasive species is, according to executive order 13112, a species that is not native and causes harm (1).No matter what harm a species causes, if the species is native it cannot be invasive, It can be classified instead as a nuisance ....   [tags: Not Native Species, Harmful Species, Animals]

Aquatic Invasive Species Essay

- Invasive species have been destroying Minnesota waters for many years. The measures that are taken to stop and control them are not as thorough as they should be. The biggest characteristic with invasive species is that, they are not native. This means they are not supposed to be in Minnesota waters. Invasive species can be a plant or an animal, such as a mussel, fish, weed, or snail. Some effects of invasive species are that, they can kill native fish, destroy spawning beds, and cause much more environmental harm....   [tags: Minnesota, Water]

Essay on Native Species Of The Asian Carp

- 1. Privet plant and different species of the Asian carp fish depict two instances when non-native species which were introduced in Tennessee causing problems. Privet is a flowering plant native to Europe, Asia and North Africa (“Non-native Invasive Plants”). It has been introduced to grow as a hedge [boundary]. But, this plant once planted can take over the native plants and grow in dense groups. Currently, the Great Smoky National Park crews work up to “550 work hours each year” to remove privet plants (“Non-native Invasive Plants”)....   [tags: Invasive species, Introduced species, Carp]

Invasive Alien Species: Disrupting and Changing the Normal Ecological Functions

- Introduction Invasive alien species are disrupting and changing the normal ecological functions of biomes, ecosystems, and the biosphere as a whole (CBD, 2009). They are a threat to biodiversity and can cause damage to, or even eradicate native species which natural cycles and other organisms depend on. While disrupting energy flow, food chains, and shaking the structure of ecosystems to the core, invasive species create not only ecological, but also a whole host of social, economic, and health issues that affect the livelihood of almost every organism on earth, including humans (CBD, 2009)....   [tags: dominance of a foreign species, ecological issues]

Invasive or Exotic Species Essay

- Today, Plants and animals usually can travel around the world in a matter of hours to days through planes or by ship. Usually their presence is harmful, yet some scientists believe that they can actually be a catalyst for biodiversity. Invasive or exotic species have altered the Chesapeake Bay region; with both a negative and positive impact. “Exotic species are plants, animals or microbes that have been transported from one geographic region to another.” (5) They are moved from an area where their evolution balance is set, into an area where they may not have any natural competitors....   [tags: Environment, Plants, Animals]

Essay on The Galapagos National Park Service Reported

- By 2011 the Galápagos national park service reported that feral goats had been eradicated from all of the Galápagos, except for a few remaining on San Crisobal, Santa Cruz and parts of southern Isabela (Nicholls 2014). Already the positive impacts of the eradication of these invasive mammals have begun to show. In 2006 Guo reported that on Santiago, plants like cat’s claw and Galápagos guava were thriving which provides the native bird species, the Galápagos rail, with nesting grounds. Donlan (2007) also found that between 1986/7 and 2004/5 the population densities of Galápagos rail’s increased on Santiago, where mammal eradication has been successful, but populations have declined in the a...   [tags: Invasive species, Introduced species]

The Impact of Invasive Species on Ecosystems Essay examples

-             Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses....   [tags: Environment Environmental Pollution Preservation]
