Citizen science is touted as a way for the general public to contribute to producing new knowledge. But citizen science volunteers don’t always represent a broad cross-section of society. Rather, they’re often white, male, middle-aged, educated and already interested in science.
This lack of representation has several problems. It can undermine the potential of citizen science to bridge the divide between lay people and experts. It also means fewer people benefit from the chance to advance their informal science education and gain valuable life skills.
It’s important that citizen science projects engage volunteers from across society, including young people. A new Australian initiative is doing just that.
The B&B BioBlitz aims to get school students gathering data about Australia’s natural environment. This year’s event shows how citizen science in school can help develop STEM skills and make gains in biodiversity research.
More hands on deck
It’s broadly acknowledged that Australia needs more hands on deck when it comes to scientific data collection. For example, only about 30% of Australia’s estimated 750,000 species have been formally named and documented. Rectifying this will require an enormous uptick in information gathering.
What’s more, Australia has one of the world’s worst extinction records. Citizen science is an important way to fill information gaps, identify species’ declines and their causes, inform conservation decisions and evaluate their effectiveness.
This year’s State of the Environment report recognised the need for more citizen science. It said the level of biodiversity research required “cannot be achieved by professionals and institutions alone”.
That’s where the B&B BioBlitz comes in.

What exactly is a BioBlitz?
The B&B BioBlitz is a national school citizen science program co-ordinated by PlantingSeeds Projects – a non-profit sustainability organisation founded by the lead author of this article. The inaugural event ran in National Biodiversity Month in September this year. Both authors of this article were project organisers and educators.
Sixty schools from across every Australian state and territory participated. Participants comprised students from infants to high school, and their teachers.
Most schools are located in urban areas, which makes them particularly valuable sites for scientific research. Many threatened plant and animal species live in urban areas, yet, only 5% of citizen science projects in Australia are urban-based.
The project involved students taking images of plant and animal species in their school grounds on devices such as tablets and smartphones provided by the school. Students also recorded information such as the time, date and location of the photo.
A designated teacher uploaded the photos and data to the B&B BioBlitz project on iNaturalist, one of the world’s most popular biodiversity citizen science platforms and apps. At the time of writing, iNaturalist contained more than 121 million observations uploaded by citizens from around the world.
Throughout September, students made more than 2,300 observations in school grounds, involving 635 plant, animal and fungi species. Students could log onto iNaturalist to see a project “leaderboard”, browse the observations submitted and learn about species’ taxonomy and distribution.
A study has demonstrated young people can contribute observations to iNaturalist that are “research grade” – and therefore more accessible and potentially useful to biodiversity research and monitoring. And the longer they participate for, the better their observations become.
Observations of species during this project contributed to more comprehensive datasets that scientists can now draw upon. Of note were images of an uncommon “Balsam Beast” katydid and the iconic Sturt’s desert pea.
Almost all observations uploaded to iNaturalist are also directly exported to the CSIRO’s Atlas of Living Australia.
The pros and cons
Verbal and online feedback by students reveals how citizen science can be a practical and positive experience.
One North Melbourne primary school student said the activity made her feel “like being more a part of a community”.
One student in Darwin said the activity was “the most fun he had ever had” and his teacher reported that while taking part, the student was “the most engaged he had seen”.
But the B&B BioBlitz was not without its challenges.
Many teachers, including science teachers, had limited knowledge of citizen science and often hadn’t heard of the term. This meant that teachers needed basic education on the topic prior to any school involvement in the BioBlitz.
Teachers are busy and face many pressing demands. However, if the benefits of citizen science are to be fully realised, there’s a need to broaden teacher awareness of the practice, and improve their skills in accessing databases such as iNaturalist.

8 tips for successful biodiversity citizen science
So how can young people be helped to take a good citizen science observation? The following eight tips offer a guide:
Capture as many angles and as much information as you can. While some groups such as birds can often be recognised from a single photograph, many other taxa require multiple features for a positive identification to be made
When observing plants, photograph as many features as possible. This includes flowers and leaves (from above and below), bark, fruit if present, a branch showing leaf arrangement, and a shot of the whole plant to give a sense of its growth habit
Photograph fungi from above, below (showing the gills or pores) and the side
Record the “substrate” you find a fungus on, such as soil or dead wood, and the type of soil a plant is growing in
Insect identification can often be helped by the number and position of veins in an insect’s wing. Try and capture this by getting shots from directly above
Noting the plant you find a beetle or bug on can aid identification and provide useful ecological data
If you find a spider in a web, photographs of both the upper and undersides can be helpful
If in doubt, just record as much information as you can. You never know who might find your data useful!
