In 2007 nine plots of between 0.3 and 1ha were established across Wytham with the aim of monitoring long-term changes in tree growth rates and standing carbon biomass in response to variations in climate and edge effects from habitat fragmentation. The plots use identical monitoring protocols to others in the Global Environmental Monitoring (GEM) forest network (Marthews et al. 2012) and data from over 1000 trees in the experiment have been collected over seven growing seasons by citizen scientists, including employees from HSBC bank, which has also provided financial support for the project.

The current aims of the project are to maintain the long-term data collection programme, as this will enable climatic trends to be detected in tree growth rates, and the resilience of different species to stressful climatic conditions and edge effects.
