A discussion of efforts to balance commercial use of the land and the sea with preservation needs — and an up-close look at Coconut Island — will be among opportunities offered during an upcoming glass-bottom boat tour of Kane'ohe Bay, sponsored by the Bishop Museum Association. The two-hour boat excursion — 2 to 4 p.m. Saturday — will be led by marine specialist Rhonda Steward, and freelance researcher, writer and historian Nanette Napoleon, "The Cemetery Lady."

The tour aboard the Coral Queen will also cover the area's various land uses over time, area fishponds, marine life and ecology. Cost is $30 for adults and $25 for children 12 and under. There are special prices for association members. For reservations (required) and advance payment, call 847-8296 or e-mail trey.dodge@bishopmuseum.org.

COMMUNITY WORK DAY

VOLUNTEERS SOUGHT TO REMOVE PLANTS

Kokua Kalihi Valley's dream is to see Kalihi Valley Nature Park become a park of more than 100 acres — including more than 20 acres of community and native Hawaiian gardens, restored ancient Hawaiian agricultural walls and terraces, and new walking paths and hiking trails. But the nonprofit group needs help: Volunteers are sought by the O'ahu Invasive Species Committee to help in a community work day at the park Saturday, to remove invasive alien plants such as Koster's curse and bamboo.

The work day is scheduled to run from 8 a.m. to 3 p.m., meeting at the Church of the Crossroads parking lot on University Avenue. To sign up, call 286-4616.
