Kanuimanu (Keālia Pond)

The Island of Maui formed from two shield volcanoes that were close enough that their lava flows overlapped, forming an isthmus between them.

The oldest volcano, that formed the West Maui Mountain, is about 5,000-feet high. The younger volcano, Haleakalā, on the east side of the island is over 10,000-feet high.

The isthmus that separates the two volcanic masses is formed from erosional deposits and is the prominent topographic feature for which the island is known: “the Valley Isle.”

Keālia was once an ancient fishpond supplied with water from the Waikapū Stream in the West Maui Mountain and Kolaloa Gulch originating from Haleakalā.

Native Hawaiians may have raised awa (milkfish) and ʻamaʻama (flathead mullet) using a system of ditches and sluice gates to let nearby fish from Māʻalaea Beach into the pond.

Established in 1992, Keālia Pond National Wildlife Refuge encompasses approximately 700-acres and is one of the few natural wetlands remaining in the Hawaiian Islands. Located along the south-central coast of the island of Maui, between Kīhei and Māʻalaea.  (USFWS)

A visitor center (2012) with exhibition hall and staff offices, replacing a trailer, was dedicated and is in use at the Wildlife Refuge.  This, with the coastal boardwalk and interpretive signage, gives a great opportunity to see and learn about the Wildlife Refuge.

Seasonal conditions that occur at Keālia Pond National Wildlife Refuge make it a notable place for people to observe Hawai‘i’s endangered wetland birds, along with a diversity of feathered visitors from as far away as Alaska and Canada, and occasionally from Asia.  (USFWS)

At the turn of the century, about 40,000-ducks wintered in Hawaiian wetlands; today, that number is around 2,000. Four of the five native water birds are now classified as endangered.

Keālia Pond serves as a settling basin a 56-square mile watershed that results in seasonal intermittent flooding during winter months and dryer conditions during late summer months.

This creates open water (200-acres) and shallow mud flat areas interspersed with vegetation, which provide suitable resting, feeding, and nesting habitat for endangered water birds. During certain times of the year, the refuge supports at least half of the Hawaiian stilt population.

The pond also supports a diverse group of migratory birds from late summer (August) to early spring (April). It is one of the most important areas in the state for wintering migratory waterfowl.

Migratory shorebirds also congregate here to take advantage of the food resources along the water’s edge. As water recedes, fish are crowded into the remaining water, making them easy prey for ʻaukuʻu (black-crowned night herons).

Baitfish ponds were constructed in the early-1970s for aquaculture of baitfish species; however, the use of these ponds for waterbirds was minimal because of the thick coverage of nonnative, invasive plants on the levees and within the ponds.

This wetland is home to the endangered aeʻo (Hawaiian stilt) and ʻalae keʻokeʻo (Hawaiian coot.) The refuge is adjacent to Keālia Beach, which is a nesting ground for the endangered hawksbill turtle.  (USFWS)

The aeʻo adult males and females are mostly black above and white below, with a long, thin black bill and long pink legs.  Found generally across the Islands, they also call Keālia home.

The total aeʻo population is estimated to be between 800 to 1,100 birds, depending on the amount of rainfall in any given year. Wetlands are essential for natural foraging areas to feed juveniles.  (Goody, WHT)

With between 1,500 and 3,000 individuals, Maui’s Keālia Pond National Wildlife Refuge and Kanaha Pond Wildlife Sanctuary have the second largest population of ʻalae keʻokeʻo in the state (O‘ahu is first).

The ʻalae keʻokeʻo is dark slate gray with a white bill and a large frontal shield (extension of bill onto forehead). The frontal shield is white but some sport a small red dot which is not related to sex or age. ʻAlae keʻokeʻo have white undertail feathers that are visible when adults are defending their territory and during courtship displays.  (Lots of information here from USFWS.)

An interesting phenomenon has happened of late – the pond appears pink. “Preliminary analysis suggests that the color change appears to be the result of a single-celled organism called halobacteria. Officials with the US Fish and Wildlife Service say halobacteria are “salt-loving organisms” found in high salinity water bodies.”

“According to refuge staff, the salinity of water in the Keālia Pond outlet is currently greater than 70 parts per thousand, or twice the salinity of seawater.” (Maui Now)

Muliwai

Water flowing from the mountainside is called a kahena wai or a kahawai, a watercourse or stream. The spot from which water begins to flow is the po‘owai, it is the source of the water. The bank on either side is called kapana wai or kaʻe no ka wai or ikana wai, and the water amid-stream is called the holomoku or ihiakala.

Where the water of a slow moving stream, a muliwai, meets the sea is called a nuku muliwai, and the mouth of a shallow rushing stream, a kahawai, is called a nuku kahawai.

Water flowing over a cliff is called a wailele, waterfall. If the water divides in falling (kahe makawalu), it is called a waihi, cascade; if the water sprays (kulu makaliʻi) in falling over a cliff it is called hunawailele or wai puhia or wai ehu.   (Kamakau; Maly)

There are several types of muliwai (muli, the remains; and wai, water – estuarine systems) in Hawai‘i. The two most common are at stream mouths or where surface flow is absent but with significant groundwater discharge.

Whether they’re called a stream mouth, bay, harbor, inlet or lagoon, muliwai are the transition zones between and connecting two major land/sea habitats – the mauka forest and the ocean.

They are among the most productive ecosystems on Earth.  The muliwai is an essential nursery habitat for certain fish species in their larval and juvenile growth stages.

The muliwai is the brackish area between the stream (land) and the sea and hosts many different species of fish, birds, plants and other biodiversity and helps to filter the stream before it empties into the ocean; and, is an important area for certain fish to gather and grow.

When the ocean was rough for the fishing canoes to go out, the families would catch fish like awa, ʻaua and ʻāholehole.  (Maly)  “The families fished for ʻoʻopu nākea and ʻakua and ʻōpae in the streams and muliwai; in the muliwai had plenty ʻoʻopu, the head big like this (the size of a fist.)” “Young awa, ʻamaʻama were abundant.”  (Chun, Davis; Maly)

Some familiar examples of estuary ecosystems include Kāneʻohe Bay, Oʻahu; Keālia Ponds, Maui; Waipiʻo Bay, Hawaiʻi and Wainiha Bay, Kauai.

Threats to muliwai/estuaries are real and diverse, including development (draining, filling, damming and dredging,) fishing, recreational use, pollutants and excess nutrients, invasive species, etc.

While I was at DLNR, the issue of muliwai/estuary protection was a growing concern.  As the Hawaiʻi representative to the Coastal States Organization, we had ongoing discussions with the NOAA and others on a national level.

Locally, through the inspiration and actions by Bob Nishimoto at DLNR’s Division of Aquatic Resources, there were discussions on establishing a Center for Stream and Estuarine Research, while a partner, the Hawaii Institute of Marine Biology, would focus on marine issues.

On a national level, NOAA established the National Estuarine Research Reserve System (NERR,) a network of 29 areas representing different biogeographic regions of the United States, to protect estuaries and provide long-term research, water-quality monitoring, education and coastal stewardship.

Each research reserve is made up of a core area and a buffer area. The core area around the estuary is managed for long-term research, water-quality monitoring, education and coastal stewardship.

The reserves are run cooperatively with governmental and local partners. The goal of the reserve system is to support local knowledge and management decisions pertaining to the coastal resources of the region.

Site Selection committee members picked Heʻeia Estuary in Kāneʻohe Bay to be Hawaiʻi’s first NERR site (Hilo Bay was also considered, but, apparently, the decision was to move forward with only one, at this time.)

Designated as the 29th site in the National Estuarine Research Reserve System in 2017, Heʻeia NERR represents a partnership among federal, state, and community-based entities, all committed to a vision of resilient estuaries and coastal watersheds where human and natural communities thrive.

He‘eia National Estuarine Research Reserve encompasses 1,385 acres of unique and diverse upland, wetland, stream, estuarine, coastal, and marine habitats within the He‘eia ahupua‘a.

It encompasses He‘eia State Park to the north, He‘eia Fishpond in the center, the wetlands of Hoi to the west and south, Moku o Lo‘e (Coconut Island) to the east, and a large expanse of marine waters with patch and fringing reefs.
