Invasive Species Impacts: Why Care?

Invasive Species

Unit 2 – Invasive Species Impacts: Why Care?

Overview

What’s the big deal about invasive species? What damage could a few plants possibly cause? Non-native, alien plants and animals may seem harmless at first but their impact can be long lasting and severe. In extreme cases, they may be capable of driving a native species to extinction. When an endemic Hawaiian species goes extinct, it’s not just a loss for Hawaiʻi; it’s a loss for the entire planet. Invasive species affect more than just native Hawaiian ecosystems; they can also disrupt cultural practices, damage key industries such as tourism and agriculture, and pose threats to public health and safety. In this unit, students look at invasive species through the lens of each of these concerns.

Length of Entire Unit

Activities in this unit

  • #1 - “In Our Lifetime”: Kūpuna Stories

    Students collect stories from community members, conduct research, and view historic photos and video clips to see what has shifted in the natural landscape of Maui.

  • #2 - Raindrops and Watersheds: Size Matters

    Students recreate rain events and measure the size of water droplets that fall from simulated miconia leaves versus native forest plants.

  • #3 - Frogs on Floor Four

    Students role-play, assuming the responsibilities of Maui resort managers faced with the problem of a coqui frog infestation on the hotel grounds. By calculating the direct and indirect costs of various control strategies, students draft a budget that reveals the financial impact of invasive species on the island’s tourist industry.

  • #4 - Plagues: Past and Present

    Performing a reader’s theater, students explore the historic 1899 outbreak of bubonic plague in Honolulu. They document the causes and consequences of the outbreak. During a following class, the teacher infects select students with Glo Germ™ gel to simulate a mystery epidemic. Students use what they learned from the plague outbreak to develop an action plan, identify the pathogen, and stop its spread.

6 class periods.

Unit Focus Questions

1) In what ways do invasive species affect the natural environment of Maui? The culture? The economy? Public health?
2) How have invasive species changed Maui over time?

Subject

Cultural connections and ethnobotany. Watersheds and hydrology. Economics. Public heath and safety.

Importance

Invasive species negatively affect every aspect of life in the Hawaiian Islands from cultural practices to watersheds, the economy, and public health and safety.
