Hawaii celebrates Arbor Day on Nov. 7

November is the start of rainy season in the islands, and so the state officially celebrates Arbor Day on Nov. 7. Tree and plant giveaways have already started, and you can find a great listing of events by island on the DLNR website.

Below is a curated list of Arbor Day activities on Oahu; some have not been included because they are already sold out or at maximum capacity (such as the Arbor Day Tree Adoption in Kailua on Nov. 8)

Kuli’ou’ou Valley Trail, from 8-11 am
Bring the family (keiki and kupuna!) for the weekly Aloha Friday Watering at the Kuli’ou’ou Ridge Trail, where volunteers will help remove invasive species, plant native plants, and receive a tree (just for Arbor Day). Some trees also will be available at the Nov. 15 Community Work Day. For more info and to register, go to alohatreealliance.org/get-involved/
