The different invasive plant species and their impact on the ecosystem

While controlling or even stopping invasive species from doing what they do best can be extremely difficult, there are important steps people can take to fight back, such as advocating for new legislation and educating those who may be directly involved in taking care of the environment.

Global Intruders Across the world, the cottony cushion scale Icerya purchasi has invaded the most countries. Spray to the point of run-off, but not beyond.

Spot burning often only top-kills more mature plants. If any of these stowaway seeds become established, a thriving colony of invasives can erupt in as few as six weeks, after which controlling the outbreak can need years of continued attention to prevent further spread.

Vegetation affects how a watershed functions. Lake Ontario has benefited in particular, as its visibility has been significantly improved by the presence of the water-filtering zebra mussel.

10 Invasive Species That Helped The Ecosystems They Inhabit

The eastern North American gray squirrel Sciurus carolinensisfor example, was introduced to Great Britain beginning in In addition, cheatgrass litter is decomposed quickly compared to native vegetation.

Some deep-rooted weeds can "mine" nutrients see dynamic accumulator from the subsoil and deposit them on the topsoil, while others provide habitat for beneficial insects or provide foods for pest species.

Invaded ecosystems may have experienced disturbance, typically human-induced. Nutrient Cycling Unlike energy, many nutrients come from the mineral soil. In fact, Molnar et al. Carp, however, may also eat native vegetation, so they are released only where their impact would not be detrimental.

Francis Wolfe is a freelance writer and a noted dreamer of dreams. Lantana growing in abandoned citrus plantation ; Moshav Sdei HemedIsrael An invasive species might be able to use resources that were previously unavailable to native species, such as deep water sources accessed by a long taprootor an ability to live on previously uninhabited soil types.

If these species evolved under great competition or predationthen the new environment may host fewer able competitors, allowing the invader to proliferate quickly. The leafy spurge can be found in 20 states across the U. It wreaks havoc with the commercial fishery, fouls boat engines and propellers, obstructs landing sites, and clogs cooling pipes for power plants, leading to massive blackouts.

Environment conditions can be challenged by invasive species, such as changing the soil chemistry, which can intensify wildfires — putting all inhabitants at risk.Restoration of ecological systems in wildland areas often involves restoring species to habitats degraded by invasive plant and animal species.

The Impact of Invasive Species

Often, such invasive species exert community level impacts, such as direct competition, but may also alter ecosystem function. Restoration cannot be achieved without understanding invasive species. Where eradication of the invasive species is not realistic, control strategies must strike a balance between ecological impacts of allowing invasive species to spread and the economic realities of control measures.

Invasive species can be insects, plants, fish, or wildlife that originate in one part of the world but end up in different habitats as a result of globalization and where their presence disrupts the natural ecosystem, sometimes destroying it.

Many ELA articles discuss Invasive Species and offer methods and tools for controlling invasive plants. A valuable resource for identifying non-native or invasive plants is the Natural Resources Conservation Service PLANTS database.
