Invasive Species: An Invasive Species
What is an invasive species? According to the National Invasive Species Management Plan, an invasive species is defined as “a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health”. Invasive species will look like they belong in the environment they are taking over, however, more than likely they are over-powering a native species in their own habitat. Would you be able to identify one of the species I’m about to discuss?
North America has more than twenty-nine hundred invasive species in our environment today. I will begin by describing 2 invasive plants and then 2 invasive animals that are invading our natural species. First we have the invasive grass called “Cheatgrass”, which is scientifically known as Bromus Tectorum L. Cheatgrass was introduced into the United States through packing materials, ship ballasts, and possibly contaminated crop seed. This invasive plant is becoming widespread in the western U.S. in the higher and northern landscapes. As Cheatgrass invades ecosystems of natural communities it destroys and completely alters the site by eliminating the native grasses possibly due to fire or grazing. This plant is highly flammable and once it has taken over an area it becomes a high fire concern. Scientific research has been done to find a cost effective way to control the spread of this invasive grass. (Rimer & Evans, 2006)
