Non Native Alien Exotic Weedy And Invasive Are All Terms To Descr

Non-native, alien, exotic, weedy, and invasive are all terms to describe plants or animals that are introduced into an ecosystem where they are not usually found. So what's the problem with invasive species? Let’s look at a few examples. Invasive species currently impact half the species listed as Threatened or Endangered in the U.S. One study estimates the total cost of invasive species damage in the U.S. to be over $100 billion each year (Pimentel, Zuniga & Morrison, 2005).

In the Great Lakes region of the United States, invasive species that come from ballast water for ocean vessels are estimated to cost $138 million a year in damage (Rothlisberger, Finnoff, Cooke & Lodge, 2012). In the southeast, a vine called kudzu grows voraciously over everything choking out other plants, wildlife habitat, forestry plots, and even taking out powerlines at the tune of over $500 million (Bettcher, n.d.). The list of examples and impacts goes on. This week, we will explore the top global invasive species in your area, the damage they cause and what we can do to stop them. You can either use a search engine to find invasive species in your area (search for your state and invasive species) or you can visit: Find an invasive species in your area or somewhere you have been – a plant, animal, insect, fungus.

Include the name of the species in the title of your post – before posting, make sure to check the list so that you do not choose the same species as your classmates! Identify your geographic location and research your chosen species. Answer these questions: What is the common and scientific name (properly formatted)? Where did it originate? How did it get to your chosen location (speculate if you don’t know)? What characteristics of the species makes it successful? What are the affected native species (any plants, animals, etc.)? What efforts are underway to prevent the spread of the species? What is one thing you learned from this research?

Invasive Species in Texas: The Feral Hog (Sus scrofa)

Common Name: Feral Hog

Scientific Name: Sus scrofa

Origin and Introduction: The feral hog is descended from domesticated pigs brought to North America by European settlers. These animals escaped or were intentionally released into the wild, where they adapted to the Texan environment. Their introduction likely occurred in the 1500s with Spanish explorers, but their population grew rapidly in the 20th century due to farming practices and hunting pressures.

Reasons for Success: Feral hogs possess several traits that enable their invasive success in Texas. They are highly adaptable omnivores, capable of consuming a wide variety of food sources. Their reproductive rate is high, with sows capable of giving birth to two litters annually, each containing up to 12 piglets. They are also highly mobile, able to traverse diverse landscapes, and have few natural predators in the region, which allows their populations to expand quickly.

Impact on Native Species and Environment: Feral hogs significantly threaten native ecosystems in Texas. They compete with native wildlife for food and habitat, destroy native plant communities through rooting behavior, and introduce diseases such as pseudorabies and swine brucellosis. They also damage agricultural crops and infrastructure, contributing to economic losses estimated at over $52 million annually in Texas alone.

Management and Prevention Efforts: Several strategies are in place to control feral hog populations in Texas. These include hunting and trapping programs, as well as the use of GPS collars to monitor movements. Recent initiatives promote the use of aerial hunting and community-based efforts. Additionally, research into biological controls, such as vaccine development for disease transmission, is ongoing to manage their populations more sustainably.

Lesson Learned: One key insight from this research is that invasive species like feral hogs are incredibly resilient and adaptable, making eradication difficult but necessary. Preventative measures, early detection, and community involvement play crucial roles in managing such invasive species effectively.
