What Are Wetlands?
It’s landscape with water.
Think of it as a transitional area between land and water mass, characterized by three factors:
- Presence of plants that only grow on water
- The ground is saturated with water, leaving the soil very low in oxygen
- This saturation or standing water is present during growing season
Living on an island like Maui, we have a lot of transitional areas between the land and our ocean.

Why Are They Important?
It may just look like water flooding an area, but there are several very important things happening.
Do you like surfing or swimming in brown water? Neither do we. More importantly, neither do our coral reef ecosystems in the ocean. When we get a lot of rain on Maui, it has to go somewhere and in the end that somewhere is directly into the ocean. Imagine a flood. Rain is indiscriminate and falls on everything including mountains, volcanoes, roads, yards, parking lots, farms etc. Think of everything that comes into contact with each of those areas and how much of that could be picked up in a flood. Fertilizer, weedkillers, gasoline, oil, and even plain old dirt are all eligible to ride this water slide.
This is where wetlands come into play. Rainwater flows through watershed areas and meets wetlands either directly or through groundwater. The wetlands operate like a giant sponge and soak up the floodwater. When wetlands are properly preserved and allowed to operate, they filter out a lot of the hitchhikers we mentioned before they head into the ocean. The sponge effect reduces the floodwaters’ impact on our developed areas. Back in the day, wetlands were viewed as unkempt areas that needed to be controlled by development. Sadly, this sentiment caused us to lose many of these important areas. With the knowledge we have today, we need to work to preserve the remaining wetlands in our environment.

What Happens If We Lose Our Wetlands?
Without the giant sponge to stop floodwater, runoff erodes our coastal areas.
The same sponge action gives floodwater a place to go as opposed to our homes, yards, and agricultural areas.
Toxins in our land environment are not healthy for our ocean ecosystems. Without the wetland interface, fertilizers, weedkillers, and other chemicals picked up along the way flow directly into the ocean.
Sediment buildup on coral reefs
Dirt picked up in floods turns into life suffocating sediment that covers our coral.
Loss of habitat for native plants and birds
Hawaii has several species that are endemic to the islands meaning they are not present anywhere else in the world. Some of these species call the wetlands their home.

What’s Significant About The La`ie Wetlands?
Photos of ae`o or Hawaiian stilts in wetlands
- Ae‘o or Hawaiian Stilt (Himantopus mexicanus knudseni meaning one standing tall) – This bird is endangered and endemic to Hawaii. It has been frequently observed by Hawaiian Paddle Sports employees in the surrounding area. The Ae‘o is extremely vulnerable to predators such as mongoose, cats, and dogs as well as human disturbance.
- Auku’u or Black-crowned night heron – Native, not endemic to Hawaii
- Kolea or Pacific Golden Plover – Migratory and not native to Hawaii
- Koa Butterfly or Udara Blackburni – There are only two species of butterflies endemic to Hawaii and the Koa Butterfly is one of them.
- Bacopa monnieri Bacopa
- Bolboschoenus maritimus Kaluha, makai sedge
- Cyperus laevigatus Makaloa
- Heliotropium curassavicum Ena ena
- Ipomoea pes-caprae subsp. brasiliensis Pohuehue
- Pycreus polystachyos Pycreus
- Sesuvium portulacastrum Akulikuli
- Sporobolus virginicus Akiaki
- Waltheria indica Uhaloa

Sounds Great, What Was The Problem?
We had a very large trash problem. Aerial footage of the wetlands next to and behind the Hawaiian Paddle Sports baseyard showed large amounts of trash scattered throughout the area. The problem was the result of various factors including dumping of cars, homeless camps, and accessibility to the Salvation Army dumpster directly bordering the wetlands. The wetlands are already stressed by many factors previously addressed. Piles upon piles of trash, abandoned vehicles and furniture were not contributing to the overall health of the area.

Mahalo for your kokua!
All photos and videos on this website were taken while viewing animals from a responsible distance. Images depicting dolphins or whales in close proximity to people were taken when the animals approached the vessel, and no attempt was made to approach or otherwise disrupt these animals. All underwater photos and videos of dolphins and whales were taken with a remote device while following guidelines for responsible viewing.
