Creating a thriving wetland for wildlife in Waipahi

There are always underperforming paddocks on farm, and for the Vallely family in South Otago, that paddock was ‘Goose Flat’. A low-lying, poorly drained area that was difficult to farm and only ever carried a small amount of stock. Initially, Gerard planned to develop the paddock further. But through conversations with the local catchment group, another possibility emerged. Instead of working against the land's natural characteristics, why not work with them?

The idea grew into a wetland project that has transformed the area into a thriving habitat for native plants, fish and birdlife.

For Gerard, the project was a chance to leave a lasting legacy before retiring. For daughter Kate and her husband Scott, who are now taking over the farm, it represents their children.

Getting started

Getting started meant learning from others. Through the catchment group, the family connected with people who could help shape the idea, navigate council processes, and support their planning. With resource consent in place, the physical work began: a weir was constructed to raise water levels and earthworks reshaped the paddock to create a functioning wetland with varied water depths.

Early in the process, the project became something bigger than just the farm. Community groups, including the local Lions Club and school groups, got involved in planting and building infrastructure like bridges and boardwalks. Around $10,000 worth of native plants went into the ground, with hardy species proving most successful during volunteer planting days.

Challenges along the way

It hasn’t all been straightforward. Early planting losses showed the importance of using larger, more established plants. Water levels rose further than expected, expanding the wetland beyond its original footprint. Navigating council processes also took persistence, but support from the catchment group helped them find a way forward.

Balancing the project alongside farm operations, succession, and a young family isn’t always easy. Ongoing maintenance, pest control, and planting take time each year. But by taking it step by step, it remains manageable and rewarding.

Benefits and impacts

The results are already visible. Birdlife has increased, with fantails, waterfowl and other species now part of the landscape. The wetland is providing habitat for native fish, especially the endangered Pomahaka galaxiid and supporting a growing ecosystem. At the same time, the farm system has benefited from removing difficult paddocks from production and reducing pressure on marginal land.

For the family, the biggest impact has been the sense of pride and connection. “The project brings people together,” says Gerard, “from community volunteers to the next generation working on the farm. It’s something we can see, share and build on over time.”

What’s next

Looking ahead, the wetland will continue to evolve. More planting, ongoing care, and gradual expansion will shape its future. What began as an unproductive paddock has become a living part of the farm, one that reflects both the land itself and the values of the people who care for it.
