In honor of the end of Hawaiʻi Invasive Species Awareness Month, we are wrapping up by discussing another plant: the Christmas berry (Schinus terebinthifolia).
Don’t let the name fool you—this invasive species doesn’t bring holly or joy! Instead, it produces fast spreading, dense shrubs that take over native plants. The shrub can grow more than 20 feet tall and has green leaves that grow opposite each other. Its bright red berries form in clusters and fruit in the winter. If you are removing it, be sure to wear gloves, as it is related to poison ivy and can cause skin irritation.
Our team works hard to control this invasive plant, but community support makes all the difference. Join us for our monthly W**d N Watch event every third Thursday to help protect the refuge. DM us if you’re interested in attending this event or learning about additional volunteer opportunities.
