This dataset includes litterfall data from the experimental plots at the Climoor field site in the Clocaenog forest, NE Wales. Litterfall (natural senesced plant material) was collected in litterfall traps (12 x 7.5cm pots standing slightly proud of the soil/litter surface, emptied monthly). Litterfall was calculated by drying the contents of the traps and weighing the samples; values were calculated for each quadrat (total weight (g) only) and for each plot (total weight (g) and weight per metre squared (g/m2)). Data spans the periods Oct 1999 to Jan 2004 and July 2008 to June 2011. Data was collected by CEH staff and PhD students trained in the use of the methods. Climoor is a climate change manipulation experiment that utilises automated roof technology to produce drought and warming experimental treatments that reflect climate change predictions for the next 20-30 years.

This dataset is part of the following
Litterfall was estimated using litterfall traps. Traps measured 7.5 cm diameter and 12 were placed in each plot in 3 different quadrats (D3, E4 and E7). Traps were emptied on a monthly basis from 1999 to 2002. After 2002, litter was not emptied on a monthly basis, and occasionally was left out in the trap for a few months (this was for the same duration for all plots, ie there was always consistency across the treatments). Once collected in, the litterfall was first air dried before removal from the trap. Litter was pooled for each of quadrats (for example, the litter collected from the four pots in each quadrat was pooled, so you would end up with samples from plot 1 quadrat D3, plot 1 quadrat E4 and plot 1 quadrat E7, and so on) prior to oven drying at 75 oC overnight and weighing. Data processing Data was manually typed into and stored in an MASTER Excel file. Mean litterfall per quadrat was calculated for each plot (ie the mean of the weight of litter collected in D3, E4 and E7). Data was then multiplied by 56.6 to convert data into the units g litter m-2.
