These completed Participatory Science Platform projects connected communities with scientists as they investigated a wide variety of topics, from moths to cats, home heating to water quality, and more. More details on the completed projects are available from the relevant Project Leaders below, or from Otago Science Into Action coordinator Craig Grant.
Relatively little is known about Lepidoptera in Otago, despite the fact that they are critical pollinators and a food source for wider ecosystems. How many moths are there in Otago? Where are they found? What species do they represent? Are they affected by artificial light, and, if so, how? To answer some of these questions, schools and communities across the region teamed up with Orokonui Ecosanctuary and scientists from Landcare Research and the University of Otago.
Data was uploaded to the MothNet project page on NatureWatchNZ, where anyone can continue to add observations. The team have created user-friendly guides to make this as easy as possible. Getting communities, and especially kids, excited about moths was a key goal. Scientists worked with kids to support their interest in ecology and entomology, act as mentors and encourage them to get amongst it.

Extinct in the North Island and with only 600 birds surviving in the South Island, the native great crested grebe is a rare and threatened species. To improve its chances of survival, artificial nest sites were set up at Roys Bay Marina on Lake Wanaka in 2013. From the single pair that the programme started with, numbers have risen to over 30 pairs, and since its inception 153 chicks have fledged from this area.
Local school children connected with scientists to monitor the movements, courtship, egg laying, incubation spans and hatchings of the grebes. Their observations were complemented by 24/7 surveillance footage from video cameras focused on individual nest sites.
Though the funded project has finished, local community volunteers are continuing with its work. The data is providing insight into factors that may lead to nest failures, and how artificial nests might be improved to increase the chances of success.

Students from St Kevin’s College and Papakaio School, members of the Lower Waitaki River Management Society (LWRMS) and spectrometry experts from the University of Otago worked together to monitor water quality in the Waitaki District. This area is seeing an increase in intensive farming and irrigation, which runs the risk of negatively impacting water quality.
They used the Public Lab Kit, a small, affordable kit used by citizen scientists to detect water contaminants. After determining the accuracy of the kit, it became the basis for a prototype water-testing kit developed specifically for local community use.

By studying the specific heating and humidity needs of ten North East Valley homes, community groups worked with scientists to test the effectiveness of standard retrofitting. Their aim was to discover how to efficiently minimise energy while maximising temperatures.
Current heating and humidity upgrade strategies – insulating the ceiling, underfloor and walls, reducing draughts, installing double glazing – assume that houses are being heated throughout at all time to 18-20 degrees Celsius. Dunedin-based research shows that this is only true for 5% of the houses surveyed. That means standard upgrade plans may not be useful for many homes in the area.
One of the successes of this project was the creation of open source wireless indoor weather stations in association with Dunedin Makerspace.

Domestic cats roam far and wide, with their travels taking them through areas frequented by pests. Traps are often set for these pests, but how do they affect pet cats?
That question was the central focus of this project, which involved twelve pet cats owned by kids from Waitati, Karitane, Port Chalmers and Purakaunui schools. The cats’ movements were tracked using GPS and video cameras, providing a picture of their range and activity.
Data from the project may be able to help local and national efforts to catch pests, not pets.

Wanaka Primary School pupils worked with staff at the Plant and Food Research station in Clyde to trap codling moth and monitor local infestations. They used the information they collected to customise pest control methods in use around the country to be effective in and around Wanaka.
Students also used timed searches and traps on selected plants to study the composition of the leafroller species in the area.
Codling moth and leafroller larvae eat their way into pip-fruit to the seeds. This damages the fruit and leaves tell-tale holes filled with frass (the excrement/debris produced by the caterpillar). The codling moth problem is becoming more widespread in Wanaka and the surrounding area, with over 80% of fruit on trees showing codling moth damage.

This project connected members of the Visual Impairment Charitable Trust Aotearoa (VICTA) with Otago Polytechnic’s School of Occupational Therapy to look into how much light those with low vision need to get around and do things safely.
In Phase One, the project was introduced to community groups like Age Concern and VICTA; the light level needs of a small group of participants were tested in Phase Two. Phases Three and Four focused on finding solutions and developing products to help VIPs navigate their environments safely and successfully.

Students from Wanaka Primary School and Mount Aspiring College teamed up with Wanaka Lake Swimmers Club, the Ruby Swim and Touchstone to investigate threats to the swimming experience in Lake Wanaka, such as invasive jelly-like algae called ‘lake snow’. Researchers from University of Otago, Otago Regional Council and Aspiring Environmental were also on board.
Following a workshop with specialists, the project team designed a protocol for swimmers to collect data. They also put together a survey of drains flowing into the bay, examining the quality of both storm and standing water. Local school children monitored these outflows and the lake water quality.
The rigorous study design and objective scientific measures tested the community’s concerns and observations, using accredited scientific laboratories. Their aim was to enhance the understanding of the local community and swimmers about the water quality in Lake Wanaka.
Project findings were presented at several public meetings and communication of findings included publishing several local news items, showing community activity in understanding the effects of the human environment on Lake Wanaka.

Do tamariki and their whānau know how much sugar is in fizzy drinks and processed foods? Are they aware of the impact sugar can have on teeth and general health?
These questions and more were explored by the children and families from Te Kura Kaupapa Māori o Ōtepoti together with researchers from the Faculty of Dentistry and Department of Human Nutrition at the University of Otago.
Tamariki worked with experts to create experiments that explored the effects of sugar on their bodies and teeth. They also examined the amount of sugar in their food and drink.
Throughout the project, the students and their families learned about oral hygiene, teeth brushing and healthy eating choices. Their oral health was examined at the beginning and end of the project.
Tamariki and their whānau received regular newsletters and reports, and a community hui was held in November to discuss the findings.
The long-term aim of this project is to reintroduce native species like the kākā to the North East Valley, Opoho and Pine Hill areas of North Dunedin.
The first step was to find out which native species already inhabit the area. Kids from North East Valley Normal School, Opoho School, Dunedin North Intermediate and Islington Street Early Childhood Centre collected data and uploaded their findings to NatureWatch NZ.
They designed a bird feeder that encourages native species into the valley and came up with a plan to protect these species from predators.

At what rate do electric vehicle (EV) batteries lose their ability to hold a charge, and how far can they travel before this happens? How do car load and ‘Eco’ settings affect energy efficiency and EV range? Where should we position rapid chargers to best enable electric vehicle journeys away from home base?
To help answer these questions, members of the electric vehicle community across Otago worked with experts to design experiments and perfect software to gather and report EV usage data – travel, charging, efficiency, cost and battery life. The project quickly spread beyond Otago so that electric vehicle owners and operators from Northland to Southland uploaded their data each month.
By the end of the first year’s Participatory Science Platform grant, Flip the Fleet amassed a communal database of 2,933 monthly records, each with between 5 and 15 EV performance measures from over 700 EVs.
Participants also filled out regular ‘1-click surveys’, answering questions about the limitations and possibilities of electric vehicle use.

Community members and scientists joined forces to monitor moths, skinks, birds and seedlings on Quarantine Island/Kamau Taurua, where predator controls have been in place since 2016. They used their findings to analyse biodiversity health on the island.
Groups who are often marginalised from scientific investigation were invited to join in, and subsidies for ferry transfers and accommodation were provided. Interviews captured personal responses to the project, and resources were developed to encourage ongoing community participation.

Students from primary schools around Dunedin worked with scientists to monitor important rocky reef habitats along the shores of Otago Harbour.
This followed on from the 2016 project Sediments and seashores – What are the consequences? It saw students and community groups work with scientists to set up monitoring sites, collect data and photograph marine communities in the area.
Their long-term aim is to understand the impact of dredging Otago Harbour to extend the shipping channel entering Port Chalmers to a depth of 14 metres.
In 2017, students helped develop a new technique to quantify the rate of sediment deposition and came up with a process to document community changes in relation to sediment cover and build-up.
This project is an extension of the 2016 Tracking Pukekura Penguins project, which saw around 50% of the little blue penguin (Eudyptula minor) population in the area tagged with RFID chips.
In 2017, the project aimed to tag the remaining penguins at the Pukekura reserve. Burrows were replaced by new nest boxes and an antenna was installed to help track the movement of the penguins over time.
Empirical data was combined with intergenerational observation to create a more complete picture of the little blue penguin colony at Pukekura. This mix of indigenous thinking and scientific analysis will be used to develop the management plan for the penguin population.
The Tomahawk Lagoon health team continued to survey the water quality of the upper part of the lagoon and, in 2017, extended their efforts to the lower lagoon. They also worked to develop an area-specific water quality monitoring kit, which may be used by other community groups in the future.
Students and teachers from local schools – Tahuna Normal Intermediate, Bayfield High School, John McGlashan College, Otago Girls’ High School and Columba College – joined forces with community members from ECOTAGO/OCEMES and water quality experts from the University of Otago, the Department of Conservation, Otago Regional Council and Otago Fish and Game.
Towards the end of the year, participants invited the local community to a 1-day symposium at which they presented their findings.

Naseby – with its low level street lighting, generally clear skies and proximity to the Otago Rail Trail – is ideally located to take advantage of the growing popularity of night sky tourism.
This project aimed to find the best location for a public viewing platform, while also monitoring local light pollution and street light locations. Baseline data was used to advise the Central Otago District Council as they worked to minimise light pollution and roll out LED street lighting. This also fed into a community-wide attempt to achieve international dark skies accreditation.
Local school kids and community members got involved in workshops and training sessions given by the Dunedin Astronomical Society, who were a key partner in the project. Naseby Vision held a very successful stargazing event for both locals and holidaymakers.
