Key Takeaways:
- An electronic gate will be installed at the Lake Taharoa boat ramp to prevent the spread of the invasive freshwater gold clam.
- The gate will require boat owners to complete an online cleaning checklist before being given an access code.
- The gold clam is a highly reproductive and destructive pest that can alter ecosystems and clog infrastructure.
- The installation of the gate is a compromise between groups who want to protect the lake and those who want to continue using it for power boating and other recreational activities.
- The gate is not a foolproof solution and relies on self-certification and trust.
Introduction to the Issue
The Lake Taharoa, located in the Kaipara District, is a popular spot for swimming and boating. However, the lake is under threat from the invasive freshwater gold clam, which has already been found in other parts of New Zealand. The gold clam is a highly reproductive and destructive pest that can alter ecosystems and clog infrastructure. In an effort to prevent the spread of the clam, an electronic gate will be installed at the Lake Taharoa boat ramp. The gate will require boat owners to complete an online cleaning checklist before being given an access code.
The Gold Clam Threat
The gold clam is originally from Southeast Asia and has caused havoc with ecosystems and water infrastructure around the world. It has never been successfully eradicated and is considered a major threat to New Zealand’s freshwater lakes and rivers. The clam can reproduce rapidly, with up to 400 babies per day, and can smother everything in its path. It can also clog pipes and infrastructure, causing significant economic and environmental damage. The Northland Regional Council’s biosecurity manager, Nicky Fitzgibbon, has warned that if the gold clam were to spread to the Kai Iwi Lakes, the result would be "devastating" for biodiversity, recreation, and cultural values.
The Debate Over Access
The installation of the gate is a compromise between groups who want to protect the lake and those who want to continue using it for power boating and other recreational activities. Some groups, including the Te Kuihi hapū, have been calling for a total ban on power boats, citing the risk of petrol pollution and the spread of the gold clam. However, others, including local business owner Rodney Field, argue that a ban on power boats is unfair and that other types of boats can also spread the clam. The Kaipara District Council has resisted restrictions on Lake Taharoa in the past, but has now agreed to allow the gate to be installed.
The Gate and Self-Certification
The gate will rely on self-certification, with boat owners required to complete an online cleaning checklist before being given an access code. While the gate is not a foolproof solution, it is seen as a step in the right direction. Nicky Fitzgibbon has acknowledged that the gate is not a "golden solution" but is a way of encouraging people to do the right thing. The gate will be monitored by biosecurity staff, but only during peak summer months. The Northland Regional Council will cover the costs of installing and maintaining the gate, which is estimated to be around $40,000.
Community Reaction
The reaction from the community has been mixed, with some supporting the installation of the gate and others opposing it. Some holidaymakers, such as Lucy Thurston from Sydney, have expressed concern about the spread of the gold clam and support measures to protect the lake. Others, such as Howard and Anne Frost from Te Awamutu, have expressed concerns about the impact of a total ban on power boats on the local economy. Local business owner Rodney Field has supported the gate, but has also criticized government agencies for being too slow to act against the gold clam threat.
Conclusion
The installation of the electronic gate at the Lake Taharoa boat ramp is a step in the right direction in the fight against the invasive freshwater gold clam. While the gate is not a foolproof solution, it is a compromise between groups who want to protect the lake and those who want to continue using it for recreational activities. The gate relies on self-certification and trust, and it is essential that the community gets behind the effort to protect the lake and its ecosystem. The Northland Regional Council and other government agencies must continue to monitor the situation and take further action if necessary to prevent the spread of the gold clam and protect New Zealand’s freshwater lakes and rivers.
