Lake Horowhenua’s Fight Against Weeds: A Slow Path to Recovery

Lake Horowhenua, known as Punahau to the local Māori, is a shallow dune lake near Levin, New Zealand. Once plagued by pollution, the lake now faces a persistent challenge: an overabundance of invasive aquatic weeds. This ecological threat has sparked a determined effort to restore the lake’s health, with a unique solution emerging as a beacon of hope.

The Invasive weed Problem

Invasive aquatic weeds pose a significant threat to Lake horowhenua’s ecosystem. These non-native plants outcompete native species, disrupting the delicate balance of the lake and its surrounding habitat. This overgrowth can lead to a decline in water quality, reduced oxygen levels, and habitat disruption for fish and other aquatic life.

A Novel Solution: the “Waterworld” Weed Harvester

Enter the “Waterworld” machine, a specially designed weed harvester that resembles a hybrid of a boat and a tractor. Skippered by Julian everth,this innovative contraption is making a considerable impact on managing the rampant weed growth.

“It’s not a Ferrari,” Everth admits. “It’s a weed harvester essentially. A very slow-moving barge is probably more accurate.”

Equipped with paddle steamer-like wheels and teeth resembling a giant lawnmower,the “Waterworld” slowly traverses the lake,effectively cutting and scooping up an extraordinary ten tonnes of weed per day.

Lake Horowhenua’s Fight Against Weeds: A Slow Path to Recovery

Nestled in the heart of New Zealand’s North Island, Lake horowhenua is a body of water facing a formidable foe: invasive aquatic weeds. These tenacious plants pose a significant threat to the lake’s delicate ecosystem and the cultural heritage it holds for the local Muaūpoko people.

For decades, the lake has grappled with rampant weed growth, a direct result of excessive nutrient levels. The excess nutrients act like fertilizer, fueling explosive plant proliferation, much like an overgrown lawn. This unchecked growth has far-reaching ecological consequences. “We’re harvesting the same as you do with your lawn,” explains Logan Brown, freshwater manager for Horizons Regional Council. “And the reason for that is when these plants grow like crazy, thay actually change the pH in the water column.”

The consequences of this pH change are multifaceted. The lake’s water quality has consistently ranked among the poorest in New Zealand. Overabundance of nutrients and weeds trigger harmful algal blooms, disrupting the balance of the ecosystem. These blooms deplete oxygen levels, suffocating fish and other aquatic life. The prolific weed growth also hinders recreational activities,impacting the aesthetic appeal and usability of the lake.

A Collaborative Effort for Restoration

Recognizing the urgency of the situation, Horizons Regional Council and the Muaūpoko iwi have embarked on a long-term project to restore Lake Horowhenua. The centerpiece of this restoration effort is a specialized weed harvester, one of only two such machines in the country. This cutting-edge technology plays a crucial role in controlling the spread of invasive species, specifically curled pond weed and oxygen weed.

“The state of the Punahau has a significant impact on the spiritual wellbeing of our people,” emphasizes Dean Wilson, deputy chair of the Lake Horowhenua Trust, which represents the lake’s owners. “Our lake has been the price paid to create wealth and support growth in this region for over a century.”

The weed harvesting process, which takes approximately seven weeks to cover the entire lake, removes a significant amount of biomass. Last year alone, a record 400 tonnes plus of weeds were removed. This harvested material is then transported to a green waste center in Feilding, where it is recycled into compost, minimizing the environmental impact.

Signs of Hope

While the sheer volume of weed hasn’t dramatically decreased after four years of harvesting, the lake’s water chemistry is steadily improving. A notable sign of progress is the reduction in algal blooms.

deanna Hanita-Paki, a trustee with the Lake Horowhenua Trust, observes encouraging signs, including the return of gray mullets and native plant life. These signs suggest that the ecosystem is responding positively to the intervention, albeit gradually.

The fight against invasive weeds in Lake horowhenua is a marathon, not a sprint. It requires sustained commitment, innovative solutions, and collaborative efforts from various stakeholders. the ongoing dedication of local communities and agencies offers a glimmer of hope for the lake’s future.
