What if I told you an ecosystem covering just 1% of the Earth rivals the carbon storage of all the world's forests combined?

When we talk about capturing carbon, we usually picture planting trees. But the data tells a completely different, hidden story about our wetlands. Here’s the breakdown:

🌏 𝗧𝗵𝗲 𝘀𝗶𝘇𝗲 𝗶𝗹𝗹𝘂𝘀𝗶𝗼𝗻: Forests cover roughly 30% of our global landmass, while wetlands (like peatlands, mangroves, and salt marshes) cover just 1%. Yet, despite their tiny footprint, the total global carbon banked in wetlands is nearly identical to all the world's forests.

🌱 𝗧𝗵𝗲 𝗱𝗲𝗻𝘀𝗶𝘁𝘆 𝘀𝗲𝗰𝗿𝗲𝘁: How’s that possible? It comes down to density. Forests store carbon above ground in their biomass (wood and leaves) and in shallow soils. Wetlands pack it deep underground.

Hectare for hectare, wetlands like peatlands can store more than 10 times the carbon of a typical forest. They’re the undisputed heavy lifters of climate resilience.

Protecting these dense carbon vaults is critical – but the rules around them are shifting.

Did you know there isn’t even a definition of a "wetland" in the Bills set to replace the RMA?

Championing wetlands might feel like it’s slipping off the legislative agenda right now, but these crucial ecosystems need our focus more than ever. Here’s why:

In a storm, wetlands are our first line of defence. Like a giant sponge, they soak up floodwaters and let sediment settle, shielding our land from damage. In dry seasons, they become a lifeline – slowly releasing stored water to keep our local waterways flowing.

Helen, one of our passionate directors, spoke to The Post recently about the future of public participation and the potential impact of the proposed resource management reform on communities.

The Planning Bill and the Natural Environment Bill would significantly limit participation and the right to appeal decisions. In some cases, it would also require councils and, by extension, communities to pay for planning controls that significantly affect people’s ability to develop or use land. Things that a community cares about, such as heritage or landscape values, may become too costly to protect, or they may not be able to have their say at the local level, where most busy people only engage on matters that directly affect them.

New planning laws will leave communities with little say in local development decisions, a planning expert warns.

For seven years, our very own Debbie Donaldson has been helping communities protect Aotearoa’s night skies. She’s worked with groups in Kaikōura, Coromandel and Wairarapa to include provisions in district plans that help to establish Dark Sky Reserves.

Light management policies and rules in official documents, such as district plans, are required for Dark Skies International accreditation. But the proposed Planning Bill and Natural Environment Bill have removed any reference to amenity values, including visual effects.

This shift could make it much harder to protect the darkness of the night sky in these important places, impacting both people’s desire to connect with nature and species’ ability to exist in more natural environments.

Check out the article link below, where Deb talked to The Post about this:

The quality of Wairarapa’s dark sky reserve could be under threat by the biggest shake-up of the country’s planning laws in a generation.

When Finding Nothing is Actually a Win! (and Science!)

Science isn't always about flashy breakthroughs. Sometimes, negative results are just as valuable. In our latest blog post, science communicator extraordinaire Rachel explores the importance of "null" findings in the scientific process.

Even when you don't find what you expect, the data you collect helps us understand the world around us a little bit better. Read all about it here: https://www.kahuenvironmental.co.nz/blog/blog-post-inanga-whitebait-search

P.S. Huge shoutout to Rachel for finding peace with the process!

Sometimes, you don’t see expected outcomes or events - that's life, that's science, that's freshwater inanga (whitebait) surveying.
