Community Workday 4th Saturday monthly!

Posted by Kirstie

Waipa hosts a community workday every 4th Saturday of the month from 9am to 12p, open to all and followed by lunch on us!

The work is always different, depending on what is most in need of extra malama.

Our workday takes place in one of the three ahupua'a sections (mauka, kula or kai) and includes work like controlling invasive weeds and planting native trees or other useful /edible plants.

Please RSVP to Kirstie via text to (808)651-1400 or via email to  We provide lunch so when you RSVP, it helps us to make sure we have enough for everyone!

Things to BRING are shoes/boots/tabis, a water bottle, change of clothes, towel, snacks, sunscreen, gloves, insect repellant, and of course we always welcome good energy and your aloha!

Please follow us on social media (seach Waipa Foundation on facebook or waipa_ohana on instagram) or email Kirstie for up to date Community Workday information.

Waipa Stream Restoration Project

Posted by Matt

In 2011 we started an exciting new project at Waipa to restore an area of Waipa Stream that had become blocked with dense stands of hau bush over many years. While hau (hibiscus tiliaceus) has a history as a very useful resource plant in Hawaii, it also exhibits invasive tendencies in stream and wetland  environments when left unmanaged. An extreme example of this was found at Waipa, where hau had grown into the stream causing sediment and plant debris to fill up the stream channel. This degraded important spawning habitat and created substantial obstacles for migrating native fish and prawns that have to pass through this section of the stream at least twice during their life cycle.

The Waipa Stream Restoration Project was designed to remove barriers to fish passage and enhance habitat for native aquatic species in Waipa Stream. It is also improving wetland and riparian habitats along the stream that are important  for endangered native waterbirds (such as the Nene goose and Koloa duck) and the Hawaiian Hoary Bat.

As of March 2013, several acres of hau bush have been cleared along the choked reach of Waipa Stream. Much of the cleared hau material was chipped on-site to create mulch  used for erosion control in the clearing areas. In flood-prone areas where mulching is not suitable, hau is being burned with the resulting charcoal and ash harvested for use in Waipa's gardens and taro loi. Approximately 1,000 feet of the stream channel has been cleaned of hau debris, and fish passage conditions in the project area have improved already.

Outplanting of the clearings with native Hawaiian and canoe plants began in July 2011 and is ongoing. There has been a strong focus on cultural plants that will produce food or other resources that can be used for the Waipa Foundation's various educational and cultural activities and programs.

An important element of the Waipa Stream Restoration Project is monitoring the impacts of the restoration work on the stream's water quality and aquatic life. To accomplish this, monitoring programs have been established to regularly measure streamflow and water quality at various points along the stream. Also, net surveys are being performed in the Waipa Stream Estuary and snorkel surveys are being conducted in the stream at several sites to collect data about habitat quality and habitat use by native and non-native species. Interns funded by AmeriCorps and the Hawaii Youth Conservation Corps have been important in carrying out the project's monitoring programs.

Funding for the project is being provided by the Hawaii Community Foundation (HCF), The National Oceanographic and Atmospheric Administration (NOAA) and the US Fish and Wildlife Service (USFWS). Matching funds are being provided by Kamehameha Schools and The Waipa Foundation.  Volunteer efforts on this project will be extremely important to its long-term success. Over 1,000 volunteers have already contibuted to the Waipa Stream Restoration Project. A series of community workday events is planned for spring/summer 2013 . If you would like to volunteer please contact the project manager, Matt Rosener,  at or call the Waipa Foundation at 826-9969.
