Wytham Woods

Wytham Woods comprises almost 400 ha of temperate broadleaf woodland which has been owned by the University of Oxford since the 1940s. The woodland community is diverse and variable in both the ground flora and tree species composition and structure.

The UK climate has relatively mild winters and cool summers. Rainfall is evenly distributed throughout the year while January is the coldest month and July the warmest. The mean annual rainfall is 726 mm, and mean annual radiation is 118 W/m2.

Access is by walking from the Oxford University John Krebs Field Station in Wytham, or by (limited, permit holder-only) car access through Wytham village.

Congratulations to the GEM team (Chris, Yadvinder & Liana) who co-authored a paper in Nature this week (cover story):

"The paper answers a long-standing question about the net carbon balance of the Amazon forest. It uses aircraft flights throughout the year at four different locations to measure the change in carbon dioxide concentration if air as it passes over the Amazon Basin. The study shows that in wet years and wet seasons the Amazon is a net sink (i.e. absorbs carbon) from the atmosphere, but in dry years and dry seasons it is carbon neutral or a source of carbon. Our main contribution in Oxford was to provide insight from our RAINFOR-GEM intensive monitoring plots across Amazonia, which suggest that the loss of the carbon sink was caused by a reduction in photosynthesis."
