Yr13 Geographers were invited to join the A-Level Biologists in surveying the physical characteristics of the River Tud Woods just off the Marriott Way in Norwich.  

As part of the Geography A-Level students study the Carbon Cycle and its significance to the globe. In the morning students undertook a survey of the carbon stores within the woodland biomass and soil. This involved measuring tree circumference and height, as well as soil depth.  

We then walked to a nearby open grass pasture where we measured soil depth. Once data had been collected from both sites, students were able to make (several!) calculations to determine the amount of carbon store in the contrasting environments.  

The final calculations record that there were approximately 4000 more tonnes of carbon stored in an acre of woodland compared to grass pasture! It highlighted the significance of woodlands as a global carbon sink and the impact that deforestation could have on the enhanced greenhouse effect should these stores be removed.  

In the afternoon, the Geographers supported the Biologists in doing kick-sampling of the River Tud. Students were able to broaden their general knowledge by helping to identify river fauna. Alas the biggest take away from this might have been that Mrs Moss needs to buy some wellies that don't have massive holes in!!
