The Rimurimu Project 2020


“Imagine the blue-belt of Wellington sustaining a healthy and vibrant Ocean Forest, able to absorb more carbon than trees, improving water quality and providing habitat for thousands of marine creatures.”

These forests have helped our oceans thrive. Now they need our help.

This year Mountains to Sea Wellington launched the Love Rimurimu project. Our long-term vision aims to see our communities developing a much greater understanding of the vital ecosystem services provided by rimurimu (seaweed) and to work together to pilot seaweed forests restoration activities in Wellington’s marine area. The project has been supported enthusiastically by an active group of technical experts from NIWA, Victoria University, Department of Conservation and the Wellington Underwater Club. Numerous new resources have been developed, and the project has been a focus across our Community Snorkel Days, gaining wide community support and interest.

We think Wellington is the perfect place to lead innovation and sustainable restoration.
Join us (and many others) on this journey!

Seaweed (rimurimu) provides a wealth of ecosystem services and opportunities:

  • Enhances biodiversity by maintaining vital food webs and habitat.
  • Improving water quality
  • Rebuilding marine ecosystems
  • Providing innovative & traditional solutions to many modern day challenges including food, textiles, materials and medicines.
  • Fighting climate change by absorbing carbon (and a potential tool for long-term carbon sequestration)

Community Events

Our community snorkel events this year have had a seaweed focus to them to align with the LOVE RIMURIMU Project.  We invited volunteer seaweed experts from NIWA, VUCEL, Wellington Underwater Club and the Friends of Taputeranga Marine Reserve Trust to support these events.  Experts provided  participants with the opportunity to engage with seaweed samples, ID guides and other interactive materials, including a virtual reality headset when onshore. These events took place across greater Wellington over the 2019-2020 summer (check out our Events page).

Education

The Mountains To Sea Wellington team is working with students from across Wellington exploring the diversity of our local seaweeds, their role in the oceans and their connection with climate change.

The education programme has been funded through Curious Minds  and is known as The Rimurimu Project. It’s intended that these young people will also be piloting restoration in Wellington with support from scientists, iwi and local government, pending approval and ensuring best practice. They will then go on to share their learning with others in the community.

The schools involved in The Rimurimu Project are Mana College, Scots College, Te Kura Kaupapa Māori o Ngā Mokopuna and Koraunui School.

This project is widely supported with leading experts from the Department of Conservation, Experiencing Marine Reserves, Victoria University, NIWA, Wellington Underwater club and many others.

Term 1

Into the (sea)weeds

In the first class session the students were introduced to the ins and outs of Seaweed. A brief lecture on structure and importance of their ecosystems and habitats, and the three different groups of seaweed; Browns, Greens and Reds. Each student received their own personal journal to record their notes, drawings and activities in. The MTSW team also brought a couple different types of seaweed for the students to begin familiarising themselves with.

Ngā Mokopuna meets with experts

Students from Te Kura Kaupapa Māori o Ngā Mokopuna were incredibly lucky to have seven seaweed experts come and present to them in their first class session. These seven fantastic experts shared an amazing wealth of knowledge with the students, from history and uses, to even sharing some pickled Neptunes Necklace on cheese and crackers.

Beneath the waves

The Students identified samples of seaweed on land before exploring their local Taputeranga Marine Reserve. Diving beneath the waves they were able to explore the amazing habitats that the seaweed forest creates. During the field trips, the students went out with quadrants and transects to observe the biodiversity of sea bed. They could quantify the different amount of organisms in the habitat in order to understand how well it was doing. They compared the observations and data between a Marine Reserve and open areas to see how well an ecosystem survives without human influence.

“A completely new kaupapa for us. This is exciting for me as a teacher to be doing new learning and the excitement and enthusiasm rubs off on our rangatahi. The engagement of whanau in the learning. Not just immediate family but wider community from both our kura and wider Stokes Valley.

– Dianne Christenson, Teacher at Koraunui School

Photosynthesis experiments

The use of newly developed classroom experiments allowed students to observe seaweed producing oxygen, and to measure seaweeds ability to absorb CO2 from water. This lead to a great discussion around where seaweed sits in the food-web and all of the amazing things it does to support its local ecosystems. These experiences and discussions have increased understanding of the vital ecosystem services provided by seaweed and will provide a strong knowledge base for Term Two.

 

Term 2


Virtual classroom

In term two we are diving deeper into the beautiful world of seaweed. After a great introduction in term One, and in wake of current pandemic circumstances, MTSW has created a virtual based curriculum for teachers to use on a platform call MakeRipples.

 
 
 

What comes next?

We want to see our marine environment thrive. To achieve this outcome active restoration and management in the marine environment is needed.

OUR VISION: “Wellington harbour and the blue belt has a flourishing ocean forest, cared for by our local communities. Our seaweed forests are valued for their beauty and ecosystem services – absorbing carbon, steadily improving water quality and as a home to an increasing abundance of marine life”
