Wakelyns timber tree data 2009-2019

Wakelyns Agroforestry is a diverse organic agroforestry system in eastern England (52.4°N, 1.4°E) which incorporates four silvoarable systems; short rotation coppiced (SRC) willow, SRC hazel, mixed top fruit and nut trees, and mixed hardwood trees with 10-12m-wide crop alleys between tree rows. Tree trunk circumference at 1.3 m above ground of all 363 trees in the mixed hardwood system in Far Field has been measured in August 2009, May 2016 and October 2019. Tree height of the same trees has been measured using a clinometer in September 1996, August 2009, May 2016 and October 2019. Since winter 2013/2014, pollarding and coppicing of selected trees within the system has been carried out. For those trees that have been pollarded, the height of the cut, and the height of the regrowth has been measured, as well as circumference at 1.3 m above ground.
