In times of heavy rainfall, water can rush off farmland, carrying soil, nutrients and contaminants into waterways - and adding pressure downstream.

In this episode, we sit down with Laura Simpson from the Mangaone West Catchment Group to learn how detainment bunds help improve water quality alongside more familiar methods such as fencing off waterways, riparian plantings and wetlands.

Laura explains how understanding your local landscape, soil type, and water quality testing insights is crucial when deciding which tools to use for improving stream health. We also talk about the broader catchment-wide mindset and the importance of working together from source to sea to create resilience in our landscapes.

Ultimately, healthier waterways means healthier farms, ecosystems, and communities.

Detainment bunds are not a silver bullet. But in the right places, they can help slow water, reduce sediment loss, protect wetlands, and keep more soil and nutrients on the land where they belong.

Here are some of the key topics we discussed:

• What detainment bunds are and how they work.
• How detainment bunds can help slow floodwater and reduce sediment loss.
• Why soil type and local landscape knowledge matter.
• The importance of regular water testing.
• How detainment bunds can work alongside wetlands, riparian planting and fencing.
• Why reducing sediment upstream benefits waterways further downstream.
• The importance of catchment-wide collaboration.
• Conservation outcomes and swimmable rivers.
• And much more…

🎙️About the podcast:

The People Helping Nature podcast is brought to you by Conservation Amplified, a registered New Zealand charity.

We are on a mission to help make conservation mainstream by amplifying the awesome stuff people are doing to help nature all around Aotearoa New Zealand.

Because when people are aware, connected to the ecosystems around them and care enough to take positive action, only then will we see lasting change.

Listen in and follow us to start or deepen your journey.

How do you mobilise a nation for nature?

Most New Zealanders say nature matters to them. But care alone isn’t creating the level of action needed to protect it.

In this episode, we sit down with Vicki Connor, Chief Advisor Public Affairs at the Department of Conservation, for a deep dive into DOC’s “Always Be Naturing” campaign - the public-facing platform for its wider Mobilising for Nature programme.

Informed by audience research, the campaign is built around a persistent challenge: if people already care, how do you turn that care into meaningful action at scale?

The research also revealed a disconnect - most New Zealanders believe nature is doing relatively well. In reality, the situation is far more fragile, with 4,000+ native species threatened or at risk of extinction.

We unpack what the campaign is actually trying to do, why DOC chose to broaden the frame from “conservation” to “naturing”, and how connection to nature can become a more accessible entry point for the people and businesses who care but don’t yet know where they fit in.

We also explore more broadly how nature should be communicated in Aotearoa if we want to reach beyond the already-converted and make it easier for communities, businesses, and everyday people to participate.

This conversation is especially relevant for people working in conservation, communications, behaviour change, community engagement, and anyone curious about where nature storytelling in New Zealand is heading next.

Here are some of the key topics we discussed:

• What Always be Naturing is and how it fits into DOC’s wider Mobilising for Nature programme
• Why the gap between caring and doing is such a major challenge
• How research and audience insights informed this campaign
• Why DOC is focusing on connection, relevance, and everyday action
• Reaching younger and urban audiences without losing the bigger picture
• Changing perceptions about the state, role and value of nature in our everyday lives and society
• And much more…

Australian brush-tail possums are one of the most widespread and damaging introduced pests in Aotearoa New Zealand, with an estimated ~30 million around the country.

They are wreaking havoc on both our native plants and animals, and they put pressure on our ecosystems, farms, and the wider economy. Most of the time, we respond by suppressing possum numbers. But on Banks Peninsula, a different approach is taking shape.

In this episode, we sit down with Ollie Rutland-Sims from Pest Free Banks Peninsula to learn about their possum elimination programme: A bold mission, strategically working to drive possum numbers to zero in their area under the ethos that “offence is the best defence”.

As Ollie explains, “we're now dealing with quite a legacy problem and a population that really, the only checks and balances on it are coming from human inputs”

Ollie shares Pest Free Banks Peninsula’s 4-stage elimination strategy: Knock-down → mop-up → surveillance → and lastly the defence phase after a block of land has been declared possum-free.

It’s an approach that’s working, with 5,800 hectares already declared possum-free - and could be used as blueprint for possum elimination throughout the country.

We also talk about mindset and the need to constantly deliver professional, spot-on work for this elimination approach to work: Continuous learning about your target species and constant improvments are key to success.

Amazingly the benefits of this mahi reach far beyond positive biodiversity and conservation outcomes, with local farmers, community, and the economy also gaining.

This project shows that eliminating a pest species in an open system on the mainland is not only achievable but also an investment in the future.

Here are some of the key topics we discussed:

• Why brush-tail possums were introduced into NZ.
• Why they’re such a big threat to our native flora and fauna.
• The benefits of possum elimination vs. supression.
• Their 4-phase elimination approach.
• How reinvasions are managed in an open mainland system.
• The long term cost savings of elimination vs. suppression.
• The importance of social license and relationships with private landowners.
• What to do when you see a possum on the Banks Peninsula.
• And much more…
