Join the OISC to help remove invasive manuka (Leptospermum scoparium), on Waiau trail on Saturday, Sept. 13.

The project runs from 8 a.m. to 3 p.m.

Manuka, New Zealand tea tree, is a ornamental shrub native to New Zealand and Australia, which grows up to 20 feet 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 natives 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.

Come help OISC prevent its spread!

Take along more water than you think you will need — at least 2 quarts. Bring gloves, hat, sunscreen, lunch, rain jacket, long pants, long sleeves and sturdy walking shoes. No slippers! Pack a good hearty lunch because we will be working hard!

Meet at the Church of the Crossroads parking lot. Going mauka on University Avenue, take your first left after the King/University intersection onto Coyne St. Then take your first right onto Kaialiu Street. The parking lot is located on the right, just after the road curves.

RSVP by Thursday, Sept. 11 to Julia Parish at oisc@hawaii.edu or 286-4616.
