At the end of the summer term, Year 12 Biology students enjoyed a four-day residential trip to Nettlecombe Court, a Field Studies Centre located on the edge of Exmoor National Park. During this residential trip, students undertook a range of ecological investigations in a variety of inspiring habitats, including rocky shores, streams, grasslands and sand dunes. The students developed their practical skills and deepened their understanding of key concepts in the ecological syllabus. They made valuable synoptic links by observing and analysing the natural world first-hand.

A range of mathematical skills was integrated into the course, allowing students to apply and practice calculations such as Simpson’s Index of Diversity, standard deviation, and Spearman’s Rank Coefficient. These skills were essential for analysing the data collected during their fieldwork.

Day 1 : Grassland Ecology

On the first day, students explored grassland ecology at Nettlecombe Court. They compared the biodiversity of two distinct grassland areas: one grazed by sheep and the other left ungrazed. This investigation allowed them to observe the effects of grazing on plant diversity and ecosystem structure.

Day 2 : Rocky Shore Investigations

The second day was spent investigating the rocky shore. Students examined the height of topshells (gastropods) in two areas with differing salinity levels. They compared the sizes of topshells found in rock pools with those located near a freshwater stream, gaining insights into how environmental factors influence species distribution and morphology.

Day 3: Sand Dune Biodiversity

On the third day, the focus shifted to the sand dunes. Students conducted a transect study to assess the biodiversity of plant species along the dune system. This exercise provided a practical understanding of how factors such as soil composition and moisture levels affect plant communities.

Day 4 (June 26): Freshwater Invertebrate Study

The final day involved a comparative study of freshwater invertebrates in a stream. Students investigated two distinct areas: one with faster-flowing water and another with calmer conditions. This study highlighted the impact of water flow on invertebrate diversity and habitat preferences.

After busy days spent in the field, there were enjoyable evening activities too! A fun evening was spent around the campfire with students and teachers enjoying s’mores and a lively game of charades.

Overall, the field trip to Nettlecombe Court was a valuable experience. It allowed students to apply theoretical knowledge in real-world settings, develop practical and analytical skills, and foster a deeper appreciation for the complexity and beauty of natural ecosystems.
