On 31 October and 1 November 2024, senior biology students ventured by bus and ferry to North Stradbroke Island to complete an array of field tasks as part of the Unit 3 Ecology program of study. 

Over the extremely busy two days, environmental analysis took place in the mangrove ecosystem of Myora Springs, as well as sand dune succession studies on the north east shores of Main Beach at Point Lookout. Data was collected for further examination when determining species diversity of a group of organisms based on a given index such as Simpsons’.  Students learned how to use a wide variety of field equipment ranging from anemometers and hygrometers to pH kits and iPad based data loggers. The process of stratified sampling was used to classify the biotic and abiotic field statistics at all sites visited.  All students worked collaboratively to complete the necessary tasks, including the strategic counting of hundreds of organisms covering the landscape assessed!

Exhaustion definitely set in on the first day after 2 hours in the muddy mangroves and 3 hours in the hot sand dunes, however the day was not done.  Upon arrival at the Surf Life Saving club, and after a well-earned dinner, book work and planning then took place in preparation for Day 2.  This included 5 more hours in the field, trekking over dunes up to and through the Casuarina forests.  Students not only analysed small creatures (such as crustaceans) and plant life during this time but also were able to see many larger iconic Australian species enjoying natures backyard, such as kangaroos, sea turtles, dolphin and the last of the migrating Humpback whales while on the beautiful North Gorge walk.

Although non-stop busy days were had, students’ enthusiasm made the excursion both enjoyable and interesting for all.  This form of fieldwork is invaluable in instilling students with a new appreciation for the world we live in.  Being out in the field is an irreplaceable experience in comparison to the classroom.  The importance of the work that took place is just a small insight into what many Biologists are doing each and every day.  It allowed us to assess the complex biodiverse world we are a part of and hope to maintain for further generations to enjoy!
