Many plants and animals have been introduced to Hawaii, some inadvertently, some for their agricultural, commercial, recreational, or aesthetic value. Many of these introductions have been detrimental to the native ecosystem. Education is one way to help prevent this destruction. MGF has been awarded a grant from the Hawaii Invasive Species Council, DLNR, to update eight Ohia Project lessons about native and invasive species in our islands. The update includes incorporating current scientific information and a cultural component. Here are the eight lessons:

  1. Finding the Forest, Grade 1: many unique plants and animals live in Hawaiian forests. (Not the same file listed under "out of print.") Download the draft - 498k.
  2. Introducing ..., Grade 2: freshwater species, insects, prawns and frogs have been introduced to Hawaiian streams and wetlands. Some were brought in accidentally while others were intentionally introduced. Download the draft - 327k.
  3. A Wild Wetland Journey, Grade 3: wetlands provide habitat for both native and introduced plants and animals. Introduced animals can threaten the survival of native species. Download the draft - 208k.
  4. Dispersal Bingo (Exploring the Islands TV show "Wind, Waves and Wings"), Grade 4: due to the extreme geographic isolation of Hawaii, relatively few plants and animals were able to reach and successfully colonize the islands without the help of humans. Download the draft - 270k and the bingo cards - 552k (not the same file listed under Exploring the Islands).
  5. Alien Invaders! (formerly An Innocent Introduction), Grade 5: plants and animals have been introduced to Hawaii, some inadvertently and some for their agricultural, commercial, recreational, or aesthetic value. Many of these introductions have been damaging to native plants and animals. Download the draft - 264k.
  6. To Catch a Pig, Grade 5: management of isolated or fragmented habitats requires feral animal control and prevention of new introductions of non-native species. Download the draft - 343k.
  7. Ecosystem Encounters, Grade 6: ecosystem management requires removal or control of aggressive non-native plants and animals, fire protection, prevention of new species introductions, and further research and monitoring of native species. Download the draft - 121k and the ecosystem cards - 425k.
  8. Design a Preserve, Grade 7: ecosystem management requires control of introduced plants and animals, fire protection, and research and monitoring of native species. Download the draft - 140k and the activity - 628k.

MGF will be finalizing these lessons later this year. The lessons will be distributed to schools and libraries. Please tell us what you think about our draft invasive species lessons--submit an evaluation form to MGF for each lesson you've used in the classroom.

For additional information on Hawaii's invasive species, check out our Silent Invasion resources. The Silent Invasion is an Ohia Project supplement for Grades 4-12 produced for the State Department of Land and Natural Resources and the Coordinating Group on Alien Pest Species. Five engaging activities educate students about invasive alien plants and animals in Hawaii.

Fishing at the golf course?
Looks can be deceiving.
This is how Lake Wilson in Wahiawa, Oahu looked like in 2003 when salvinia covered its surface! The fish weren't biting that day.


Clidemia hirta, or Koster's curse, is an aggressive weedy shrub that shades out all vegetation below it. It produces a lot of seeds and grows easily. It is spread mainly by man but also by birds and feral pigs.
