Tree Phenology on Exmoor

In 2006 the Exmoor Tree Condition Survey was set up in order to monitor any changes in beech and sessile oak condition which might occur on Exmoor as a result of climate change. Part of the survey includes the yearly survey of pre-selected trees to see what date the buds burst and the leaves fully emerge.

The study of the timing of these natural occuring events is known as Phenology.

A dedicated group of volunteers have recently taken up the task of carrying out these yearly surveys in order to provide a level of consistency to the data gathering. Please click here to learn more about the Exmoor Tree Condition survey.

A PDF available here contains all of the data collected to date. Although there is too little data to show any significant trends, it is interesting to note that according to the Met Office website, in 2011 we experienced the warmest spring on record and in 2013 the coldest spring since 1962. To date, bud and leaf burst occured earliest in 2011 and latest in 2013.
