This month's Oahu Invasive Species Committee service trip will be held on Saturday, November 14 from 8:00 a.m. to 3:00 p.m. at the Waiau Trail.

Manuka, the New Zealand tea tree, is an ornamental shrub native to New Zealand and Australia, which grows up to 20 ft in height with small white to pink flowers and needle-like leaves. It was introduced during forestry efforts to stabilize soils and prevent erosion. Manuka is an aggressive invader, capable of crowding or shading out native plant species by developing dense thickets and producing wind dispersed fire-resistant seeds. This tree has successfully invaded some of the most pristine native ridges and valleys on O‘ahu.

Interested individuals are to bring gloves, a sunhat, sunscreen, rain jacket, long pants, long sleeves and sturdy walking shoes. No slippers allowed. Pack a hearty lunch and snacks because we will be working hard! And most importantly, bring at least two quarts of water.

Participants can meet at the Church of the Crossroads parking lot at 8:00 a.m. and will be required to sign a waiver.

To RSVP, email oisc@hawaii.edu or call 286-4616 by November 12.
