July 2022 Thriving Southland Newsletter

Welcome to our July newsletter!

We’re headlong into our winter season now, but after the COVID-19 disruptions earlier in the year there’s a real sense of wanting to get out there and do things in the many Catchment Groups around our region.

The diversity of activity happening among Catchment Groups is fantastic and it’s always exciting to see people from other Groups attending events in other catchments. The sharing of ideas between everyone involved is great to see. Funding forums, winter grazing projects and demonstrations, kids using our new education kits in the field, and newer Groups getting stuck into water quality testing - it’s all great stuff.
During the month we held another stakeholder meeting to share all the work Catchment Groups are doing,  and update on the projects underway. It was a fantastic networking, learning, sharing opportunity, and helps further strengthen the connections.
We really appreciated the feedback on how Thriving Southland is helping empower farmers with science and knowledge shared through the Catchments Group network. Its also great to hear the recognition of the Southland Catchment groups are getting both locally and nationally for all work they are doing.
There’s a few mid-winter get-togethers happening around various Catchment Groups and plenty of other events happening this coming month, from fresh water crayfish project talks, to Regional Forum catch-ups, to field days and planning meetings.
Keep warm everyone.

Aparima Catchment Group science brochures now available

Catchment Groups have been asking for more detailed insights into their individual catchments to help their farmers to make informed decisions on their farms.

There is plenty of available information but it has never been collated into one place – until now!

We’ve pulled a whole range of information together into brochures; providing insights based on available information, bringing together published science, research, data and information on the state of water, soil and land in catchments.

They provide details on what affects water quality and how these impact the rest of the catchment, including out-of-catchment areas that may be impacted by what goes on in the catchment, such as the estuary.

All Southland catchments will get a brochure – but the first FMU completed is Aparima – with a brochure per catchment.

You can have a read of the six Aparima brochures at

    Catchment Group Events

    Recent Events

    Two recently formed Groups have hit the ground running and had Justin Kitto from DairyNZ out to talk about their local water quality. They discussed eDNA test results and looked at what creatures live in their local stream. Plans are afoot to extend the eDNA testing in more depth across the catchment. Great to see new Groups popping up, with new faces coming along.

    Hedgehope School Stream Health Study at Sinclair Covenant

    Sarah's rainbow hat and wetsuit were dragged out in late June for a stream health session with Hedgehope School.  We descended upon the Sinclair Covenant (aka Sherwood Forest at Tussock Creek), built a catchment model and then used the new stream health education kit. The students, parents and school team were fantastic and can now go home to find out the health of their streams just using a kitchen sieve and white ice cream tub and a simple monitoring form. 

    Many thanks to Hedgehope School and community for being utterly fabulous (your haka was very special), and Nan Sinclair for giving us access to your special QEII covenant. Hedgehope School rocks!

    Mid Oreti Catchment Group Seed Collecting and Sowing Session for Mini Forest Movement Project

    Lovely to spend a few hours with the Mid Oreti crew, collecting and sowing native seeds for their Mini Forest Movement Project. Hopefully these beauties will grow big and strong and be able to be given to local farmers, schools and community groups in the next few years. 

    If you, your school or business want to learn some native plant propagation skills or just lend a hand, contact Ainsley and Rosie at Come and give it a go! It’s lots of fun.

    Pourakino Catchment Conservation Trust field day checks out on-grass demo project

    We had a fascinating wander around the Mathieson family’s Ardoyne Farm at Longwood on 2 June as part of a Pourakino Catchment Conservation Trust field day looking at the On-Grass Winter 2022 Demonstration project. 

    The project is looking into a concept for wintering using various tread resilient deep rooting plant covers that, in conjunction with baleage supplementation and suitable management, allows for semi -intensive cattle wintering. It gives scope to explore wintering systems and farm systems modifications that are not dependent on wintering on crops (on or off farm).
    The paddocks will be monitored during winter and results shared with the community. Next winter there are plans for four more farms around Southland to take part in the trial, while more analysis of the deep rooting plants will be also be possible at Ardoyne Farm by then. The Pourakino Catchment Conservation Trust is working with Thriving Southland, Agricom and DairyNZ on the project. Those attending warmed up with a BBQ afterwards.

    Funding for Farmers: For better environmental outcomes

    Mid Oreti had a blast at their Funding For Farmers evening. Over 50 people came along from all over Southland to hear about different funding options for improved environmental outcomes for themselves and their Groups. Don’t worry if you missed it, as the evening was recorded, and the Group is pulling together a summary of the info from the event. Please email them if you are keen for a copy of the handout -, and Thriving Southland will share the recording of the event too via our Facebook page over the coming weeks.

    Big thanks to all the speakers who made the night such a success, and to Rosie for pulling together a wonderful supper. Thanks to everyone who came along, let's drum up some projects and apply for funding!

    A focus on wintering

    Hedgehope Makarewa Catchment Group winter crop cultivation trial

    A pilot study, run by the Hedgehope Makarewa Catchment Group and funded by Thriving Southland, with support from a range of stakeholders, was recently completed to understand how different variables affect cattle grazing behaviour and soil surface conditions, with an aim to reduce mud, protect soils, reduce degradation, and minimize the runoff from grazed crop paddocks.

    In spring 2020 farmers across ten farms, including the Southern Dairy Hub, established split paddock crop establishment comparisons. Measurements/observations were made from late May to early August 2021, with measurements of the crops staggered between sites to fit in with the farmer’s plans to graze each winter crop paddock in line with their usual winter grazing practice. It also provided easier measurement collection as each site required significant work with large distances between sites across the Southland region.

    The project highlighted the diversity of practices on farms across the region and demonstrated that there are many factors that affect winter grazing outcomes.

    An army of volunteers supported the data collection and became passionate advocates for rallying the farming community to talk about practices and good management.

    With 500 soil types, and combinations of soil types, in Southland, the study considered whether soil type influences land suitability for winter grazing.

    Soil moisture samples from study treatments, pre and post graze

    The study used surface pooling and gumboot scores as measures to indicate stock comfort and found that even a small amount of rainfall can change the soil from wet to sodden.

    Large volumes of data were gathered on crop yields and establishment methods.

    On commercial farms, data was primarily collected on soil characteristics before and after grazing, the crop yield, and other aspects of each cultivation method.

    On some properties additional measurements were taken, such as post grazing crop residuals and visual soil assessments once paddocks had been replanted.

    Farmers completed daily observations of livestock grazing the treated paddocks and data was referenced against weather events.

    The most significant learning was that the daily management of grazing stock had the greatest impact on soil damage, rather than soil type and crop establishment methods.  Although soil type did appear to influence the occurrence of surface water pooling, pugging and compaction risk.

    It highlighted that having a winter grazing plan, with planned crop husbandry and stock management, supported the best wintering successes. Farmers who carefully assessed their own situation, adapted what they did as conditions changed, and had good systems in place, had the best outcomes.

    However, the study also found that there was no silver bullet, and there was no clear ‘best alternative’ to conventional cultivation. It found that although lower yields reduced the stocking density in a given area, regulatory limitations on the proportion of the farm that can be used for winter grazing actually favours intensification. This puts pressure on farmers as they try and support sustainable agriculture, striving for high crop yields and simultaneously protecting soils.

    Different crop establishment methods

    The study found that you get out what you put in. Yields were relative to the amount of time, effort and expenditure spent on crop establishment. It found that with careful thought and preparation, many outcomes, including feed security and animal welfare, improved.

    Although low or no till options may appear to be more environmentally sustainable (from a carbon and soil structure perspective), observations from this study were of lower yields, greater weed burdens, and increased pest pressure. An unintended consequence of minimal/low till establishment was the increased need for chemical weed and pest control to help achieve a more sustainable yield. 

    The study at the Southern Dairy Hub found that for crop establishment, there were differences in yield for the fodder beet crops with direct drill and strip till compared to conventional establishment. For example, areas established by direct drill and strip till were weedier even when Italian ryegrass was sown following the crop.

    The pilot study also observed that there were several sites that had some surface pooling - but correlations between treatments couldn’t be made and would be an opportunity for further research.

    The data collected on the commercial farms was variable, and the thousands of photos and observations collected gave a unique picture of day-to-day conditions. Overall, observations indicated animals behaved contentedly for the vast majority of the time regardless of cultivation method.

    What farmers can do:

    Farmers need to carefully assess their own situation, change what they do as conditions change, and have systems in place to support the changes – ultimately good management of their crops and stock was the main factor that impacted soil conditions and mud creation.

    The study found that the following four steps would make the biggest improvement to wintering practices:
    1. Good paddock preparation and agronomy practices to achieve optimum crop yields.
    2. Utilising portable troughs, back fencing.
    3. Having a Plan B and those on the ground knowing when to implement it.
    4. Implementing Good Management Practices maximises the time animals spend in better conditions (unless it’s continuously wet)
