King’s College Biologists Explore the Isles of Scilly

Fourteen enthusiastic Lower Sixth biology pupils and two dedicated staff members set off at dawn for an unforgettable field trip to the Isles of Scilly. Departing from school at 5 am, the group journeyed to Penzance before boarding the ferry to St Mary’s, the largest of the islands.

Rocky Shores and Field Labs 

Upon arrival, the group hiked to Old Town Bay to identify algae and molluscs on the rocky shore. Pupils learned how these organisms adapt to the harsh intertidal environment. As the sun set, the team set up camp, transforming their site into a field laboratory and kitchen. Pitfall traps were installed to monitor invertebrate biodiversity around the campsite. 

Transects, Birds, and Biodiversity 

The second day began with invertebrate sampling in the grasslands of the Garrison. A visit to a local nature reserve allowed pupils to observe bird species richness. In the afternoon, pupils returned to Old Town Bay for systematic sampling using line and belt transects. Evening activities included data analysis, kite diagram construction, and checking pitfall traps. 

Off-Island Adventures and Marine Marvels 

The group took a boat to St Agnes, where they toured Troy Town Farm and learned about sustainable dairy farming. They also met Jof Hicks, who shared his zero-plastic, zero-emission lobster fishing initiative. After sampling the farm’s famous ice cream, the group crossed to Gugh to study sand dune succession. In the afternoon, a boat trip to the outer islands offered encounters with puffins, guillemots, razorbills, and Atlantic grey seals. 

Statistical Sampling and Farewell Views 

On the final morning, pupils conducted random sampling on both sides of the Garrison wall. A reflective walk along the wall offered one last panoramic view over Porthcressa Beach before boarding the Scillonian III for the return journey. A pod of dolphins provided a magical send-off as the group sailed back to Penzance. 

This immersive trip deepened pupils’ understanding of ecological principles and fieldwork techniques. Their collected data will contribute to ongoing research in collaboration with the Isles of Scilly Wildlife Trust and the Isles of Scilly Community Research Network.
