Zoanthids are an order of cnidarians (related to jellyfish) commonly found in coral reefs, the deep sea and many other marine environments around the world.

These animals come in a variety of different colonizing formations and in numerous colors. They can be found as individual polyps, attached by a fleshy stolon or a mat that can be created from small pieces of sediment, sand and rock.

We absolutely love looking at all the different zoanthids here at Kapo’o. Like hard corals, they are threatened by trampling, chemicals from sunscreens, sedimentation, and warming waters, just to name a few.

These cool creatures have been struggling here in the Kapo’o Tidepools this summer due to heavy sedimentation from storm runoff and constant trampling by folks haphazardly stepping on them.

Please, only stand in the sand. The marine life here has enough to deal with already.

Join us for our next community work day as we help our fragile reefs by reducing coral-killing erosion!

We’ll be removing invasive weeds from our Native Hawaiian Plant Coastal Restoration Project area, maintaining paths and rope borders, planting native coastal plants, removing rubbish, and much more!

➡️ 7:30am-9:30am at our project site at Kapo’o (Sharks Cove).

Gloves and tools provided (but you can bring your own!). Wear covered shoes, long sleeves, and bring sun protection and water.

Healthy coral reefs are habitats for marine life, provide food for us, protect our shorelines from impacts, cause waves to barrel, and so much more! Come help us make a difference!

Mark your calendars!

Heads up North Shore!

Repost from Hawaiʻi State Department of Health
•
A has been issued at Kaʻena Point to Sunset Beach on O‘ahu.

The Hawaiʻi State Department of Health advises beach users to stay out of waters that appear brown or murky, especially following storms or heavy rain, even if a Brown Water Advisory has not been issued in the area.

WORK DAY THIS SATURDAY!

Come join us as we plant our new pilot restoration project area at the Kapo’o Tidepools!

We began our Native Hawaiian Plant Coastal Restoration Project nearly 13 years ago to address rapid erosion around the Cove area of Kapo’o. This project, to date, has successfully removed tons of invasive weeds and shrubs and planted thousands of native Hawaiian coastal plants in their place to help stabilize the soil thanks to countless volunteers and project partners.

Now, the area where the beach meets the grass fronting the Kapo’o Tidepools is highly eroded and getting worse everyday due to heavy foot traffic, storms and runoff, and high surf in winter. It’s time to take action to help protect the fragile marine ecosystem below from coral-killing sediment.

With your help, we’ll plant native Hawaiian coastal plants that will help stabilize the shoreline, reduce erosion, and protect the Kapo’o Tidepools - the piko of the Pūpūkea Marine Life Conservation District.

Come get your hands in the ‘āina, mālama, and help make a difference in the health of our nearshore marine ecosystem!

➡️ 7:30am-9:30am at our project site fronting the Kapo’o Tidepools

Mahalo nui to everyone who came out to kōkua with this month’s Native Hawaiian Plant Coastal Restoration work day! 🌱

We had a small but mighty crew that removed over 210 pounds of invasive weeds and shrubs and planted 25 native Hawaiian coastal plants, including pōhinahina and ʻulei. 💚

We were also excited to welcome Surfrider Oʻahu Chapter and hear a little bit about the work they do to protect our oceans, waves, beaches, and coastal communities. We love building pilina with partners who share our commitment to caring for our marine ecosystems. 🌊

We have two Native Hawaiian Plant Coastal Restoration work days coming up in October. These will be especially exciting because we’ll be starting on a new area! We began our Coastal Restoration project around the Cove over 12 years ago and now we’ll be expanding into another highly-eroded area. We hope you’ll join us!

🌿 October 3 — New Area Erosion Control and prep
🌱 October 17 — Planting Day!

Come get your hands dirty, help prevent coral-killing erosion, and meet some great people along the way!

🌱🌊 NATIVE HAWAIIAN COASTAL PLANT RESTORATION WORKDAY 🌊🌱

Join us THIS SATURDAY, September 19, from 7:30–9:30 AM as we help to mālama our fragile marine ecosystem through hands-on native Hawaiian plant coastal restoration at Pūpūkea Beach Park🌿

We’re excited to welcome members of Surfrider Oʻahu Chapter to this Saturday’s wok day!🤙🏽 They’ll be joining us, sharing a little about their organization and getting to know our MPW volunteer community. A great chance to connect, learn, and mālama together! 🌊💙

No experience necessary, just bring yourself, water, sun protection, and a willingness to get your hands dirty!

IT’S GREEN!!

You may have noticed the water in and around the Kapo’o Tidepools is looking green. This is because MPW and WAI are studying the potential leakage from the Pūpūkea Beach Park restroom wastewater system using a “green dye tracer” to understand the impacts on our marine ecosystem.

“Wastewater systems release excess nutrients, harmful pathogens and toxins into the marine environment via groundwater contamination or overflows. This harms the nearshore environment by encouraging the spread of invasive algae, increasing rates of coral disease, and degrading habitat complexity.” - WAI

This project uses a human and marine life safe dye and is done with the approval of the State of Hawaii and City and County of Honolulu Department Parks and Recreation.

The dye was injected into the restrooms on Wednesday, September 9th and although we hoped we wouldn’t be seeing any in the tidepools, we are. Scientists are taking readings every day, especially at low tide, and will continue to do so for two weeks. The dye will naturally dissipate and has a half life of about 12 hours in sunlight. The results of this study will help us, along with agency partners, safeguard the health of our fragile ecosystem. We will post updates as we go. Mahalo everyone who is making this study possible!

If you’re in the area and see green, snap a photo and send it to us! Be a part of the green team!

We posted a reel on Thursday that shows the process if you’d like to take a look!
