LiHU'E, Kaua'i — Kaua'i's annual Arbor Day celebration on Saturday will feature 1,500 native plants to be given away, plus educational booths and presentations, and keiki activities.

The event will be from 10 a.m. to 1 p.m. behind Kmart at the Kukui Grove Shopping Center.

Participants can travel down "Tree Trail" between educational booths on the way to the free native plants. Naturalists from a variety of organizations will answer questions and offer information about topics like forest birds, invasive species, horticulture, endangered plants, watershed health and more.

By learning from these booths, attendees can earn an extra "Tree Token" to redeem another plant in addition to their first free tree received for attending.

Extra plants also can be obtained by turning in a weed for the invasive-species bounty. Species such as kahili ginger, Australian tree fern and fiddlewood are welcome. For more weed ideas, visit www.hawaiiinvasivespecies.org/iscs/kisc/wow.html.
