Kahikatea Fragment Enhancement Project

Kahikatea Fragment Enhancement Project

This project was funded by the Waikato River Authority’s Clean Up Fund and was completed in June 2019.

Over a two year period, this project assisted eight landowners enhance kahikatea stands on their properties. Seven existing stands were fenced from stock, and one new wetland area was fenced and planted with kahikatea to become a mighty stand two hundred years from now.

All stands were provided with some understory planting of characteristic kahikatea species that were missing from the stands, with a total of 12,454 native plants planted. The plants were sourced from the community nursery run by the Waikato Ecological Restoration Trust, and Forest Flora. The Waikato Weedbusters Squad provided amazing volunteers to assist in undertaking weeding and planting in many of the stands, while some weed control was contracted out.

Additionally, each landowner received a restoration plan for their stands so they can manage them into the future.

During the course of this project, Waikato Regional Council also updated their fact sheets about kahikatea, which you can access here:

Planting prevails over a deluge and a wasp!


Heavy rain and an agitated overwintering wasp could not dampen the enthusiasm of a group of community minded volunteers who planted over 1000 native plants at a recently fenced off kahikatea stand on the Henderson's property in Rukuhia, near Hamilton in August 2017.

The volunteers came from the Waikato Mobile Weedbuster Squad, and joined with staff and family members from the farm. The weather started out fine, but deteriorated during the morning, leaving everyone soaked by the end of the planting session.

A wasp overwintering in a karamu plant added additional drama to proceedings when it stung NZ Landcare Trust's Waikato Regional Coordinator Nardene Berry who organised the event.
While the sting was unexpected, especially during the winter, Nardene was fine and delighted with the day's achievements. Nardene said, "We achieved much more than we expected at the beginning of the day, getting all the plants in was fantastic. And I was glad it was me that was stung as I don't react badly, while we had someone in the group who was highly allergic to wasp stings! A good reminder to keep a look out for wasps even if you're not expecting them due to the season."

"I'd also like to acknowledge the Waikato River Authority's Clean Up Fund for providing the financial support for the fencing and plants," Nardene added.

Nardene returned to the planting site a few days later with a smaller group of volunteers to put rabbit protection around those plants most vulnerable to browsing. The planting work was completed by adding flaxes along the edges to provide shelter from the wind.
This was a big effort by farm staff and volunteers, but one that will have positive outcomes for years to come.

Waikato Weedbusting Squad


The Waikato Weedbusting Squad (WWS) works with Queen Elizabeth II Trust to clear weeds from various covenanted sites across the Waikato Basin. Squad members enjoy the camaraderie, the variety of sites, the satisfaction of seeing the results of a team effort and knowing they are making a positive difference in terms of restoring indigenous biodiversity.
Weeding takes place two mornings a month on different days to suit members’ availability. Work involves hand weeding, cutting and pasting or spraying – whatever people are comfortable doing.
There are usually 8 to 10 weedbusters at each session and currently eight covenants being supported. The Waikato Weedbusters Squad is always looking for fit volunteers to assist with their work, so if you like the idea of being part of a mobile weedbusting squad and are based in the Waikato, the Waikato Weedbusting Squad welcomes new members.

Alternatively, start a squad in your local area. Find others who share your passion for weedbusting:
• Start small and build up membership as you go along.
• Decide what sites you would like to tackle. Maybe there is a nuisance weed you want to
eradicate, landowners seeking assistance with restoration or local reserves in need of maintenance. You could talk to your local QE II Trust representative about covenants that would benefit from a weeding session.
• Identify a time to suit most squad members. Perhaps start with one morning a month and do more as time goes on.
• Prepare a health and safety plan of generic hazards as a base for identifying risks at a site. You can use the WWS plan as a guide.
• Consider having a team resource of tools, gloves, high-vis vests, herbicides etc. There are some starter kits available.
• Be prepared to reassess the squad’s involvement in a project if the scale of the weed problem requires alternative control methods beyond the capability of the team.
• Enjoyment should come first.
• Keep mobile. Retain the flexibility to assist and support a variety of projects. It is the diversity of sites that makes the task interesting and appeals to many weedbusters.

Weedbusting becomes an enjoyable and satisfying social activity when undertaken as part of a team.
