Scientific Name:Psidium cattleianum
This invasive plant is very common in the forests and along hiking trails. Strawberry Guava plants have no natural enemies and forms a thick cover that smothers native species. This smothering destroys the habitat and means of food for many other native animals. A Study by UH shows that areas invaded with strawberry guava wastes 27% more water than Native forests. A insect that attacks this plant has recently been released as a biocontrol that will hopefully limit the spread of this plant. ( Image by Forest and Starr)
