Our wetlands act like the kidneys of the earth, they are also home to unique wildlife and plants. The Ramsar Convention on Wetlands is an international treaty focusing on the conservation of our wetlands.Continue Reading...

At 7.30 am on a perfect West Coast morning, I took a boat trip, courtesy of Ōkārito Boat Tours, to explore New Zealand’s largest unmodified wetland.
Despite being drawn back to Ōkārito time and time again I had never ventured out on to the lagoon. I knew the trip was going to be pretty special and it certainly didn’t disappoint, with an absolute blue sky allowing views of New Zealand’s highest peaks beyond glassy, reflective water and lush rainforest. We were all in awe of this insanely picturesque place and grateful to our guide, Swade, for opening this hidden world, inaccessible by land, up to us.
World Wetlands Day
International World Wetlands Day is celebrated on 2 February around the world—a day set in recognition by the Ramsar Convention for the worldwide protection of wetlands—and this year’s theme was Wetlands & Agriculture: Partners for Growth.
In order to mark the day locally, DOC’s Franz Josef Field Base partnered with Ōkārito Boat Tours to offer seven, free boat trips for people living in the vicinity of Ōkārito Lagoon over the weekend of 1-2 February. The offer attracted 75 people (appropriately, many from rural/farming communities) from Fox, Franz, Hokitika and Haast all keen to get a glimpse of this nearby wonderland.
A precarious balance
Since 2008, when Paula Sheridan and ‘Swade’ Finch began operating their boat tours, they have noticed how even small changes in weather, wind and water levels can cause dramatic changes in the behaviour and sightings of various birds.
On this day Swade noted that wading bird numbers had been low this year due to unusually high water levels in the lagoon. We still managed to spot a good variety of birds including godwits, spoonbills, Caspian terns and several of the area’s, iconic kotuku/white heron whose only NZ breeding colony is located just up river near Whataroa. I was particularly excited by the very real possibility of seeing an Australasian bittern—but, sadly, no such luck.
Glaciers to Wetlands restoration partnership
Things are looking up for the huge diversity of species that rely on this precious fragment of the Coast. As part of its work to conserve the lagoon’s outstanding natural wealth, DOC has partnered with Air New Zealand Environment Trust (ANZET) on the four-year Glaciers to Wetlands project to restore the Ōkārito Wetland System.
Part of the project has been the creation of a community nursery in Ōkārito. The nursery will generate all the native plant species required to replant the areas at Ōkārito and Lake Wahapo. To date, thousands of seeds and seedlings have been collected, and will be grown at the nursery with the help of the community and volunteers.
Already planning for next year!
As the sun rose higher in the sky and our boat returned to Ōkārito wharf, I struggled to think of a better way to celebrate the world’s vital and threatened wetlands. Paula tells me that plans for next year include land-based activities as well as the boat trips and sausage sizzle “so people can learn even more about the balance of this ecosystem and what it provides for all of us”.
If you can’t wait that long, you might have to just get yourself to Ōkārito and check out the boat trips, kayaking, walks and kiwi tours available from this humble township for yourself.

Yesterday (2 February) was World Wetlands Day. To celebrate, we’re putting the spotlight on Whangamarino Wetland in the Waikato.
World Wetlands Day is held every year, on February 2, to mark the signing of the Ramsar Convention on Wetlands and the Day provides an opportunity to highlight the important role wetlands play in our environment.
Whangamarino Wetland is one of the largest swamp and peat dome wetland complexes in the country at 7,000 hectares. A Ramsar site since 1989, the wetland is also important to Waikato-Tainui people as recognised in the Waikato River Settlement.
Australasian bittern/matuku, black mudfish and swamp helmet orchid are just some of the threatened species thriving in the wetland. Other species include marsh and spotless crakes, fern birds, dabchicks and various gamebirds, making it a popular spot for game-bird hunting.
However, the wetland faces a number of threats, including excessive inflows of sediment and nutrients from the wider catchment, altered water levels due to the lower Waikato River Flood Scheme, predators, stock trampling and weeds. Despite these threats, large areas of raised peat bog remain in good condition, supporting communities of threatened wetland plants.
DOC has been implementing innovative wetland conservation initiatives at Whangamarino Wetland under the Arawai Kākāriki wetland restoration programme.
