- Metadata for merged abundance dataset from myForest and the Countryside Survey, for the paper “Abundance distributions for tree species in Great Britain: A two-stage approach to modelling abundance using Species Distribution Modelling and Random Forest.” Data sources The .csv file contains merged data on abundance of tree species in the UK from two sources: the Countryside Survey (http://www.countrysidesurvey.org.uk/ (accessed 09/11/2016)) and myForest (https://sylva.org.uk/myforest/ (accessed 09/11/2016)). Each row refers to a single species within a single 1km2 in Great Britain. Columns and units • FocalSp – the species referred to in that row. Species codes are: ACAMPESTRE (Acer campestre L.), APLATANOIDES (Acer platanoides L.), APSEUDOPLAT (Acer pseudoplatanus L.), AGLUTINOSA (Alnus glutinosa (L.) Gaertner), BPENDULA (Betula pendula Roth), BPUBESCENS (Betula pubescens Ehrhart), CBETULUS (Carpinus betulus L.), CSATIVA (Castanea sativa Miller), CAVELLANA (Corylus avellana L.), CMONOGYNA (Crataegus monogyna von Jacquin), FSYLVATICA (Fagus sylvatica L.), FEXCELSIOR (Fraxinus excelsior L.), PTREMULA (Populus tremula L.), PAVIUM (Prunus avium L.), PPADUS (Prunus padus L.), PMENZIESII (Pseudotsuga menziesii Franco), QPETRAEA (Quercus petraea Lieblein), QROBUR (Quercus robur L.), SCAPREA (Salix caprea L.), SCINEREA (Salix cinerea L.), SARIA (Sorbus aria Crantz), TBACCATA (Taxus baccata L.), TCORDATA (Tilia cordata Miller), UGLABRA (Ulmus glabra Hudson) and UPROCERA (Ulmus procera Salisbury). • FocalSpPp – the probability of presence of the focal species of that row, as predicted by ensemble SDMs produced using biomod2 (in R). Units are probability multiplied by 1000. • abundance.ha – the abundance of the focal tree species within that 1km2. Units are in hectares per kilometre squared, or percent cover. • AcaPp – the probability of presence in that km2, as predicted by ensemble SDMs produced using biomod2, of Acer campestre. Units are probability multiplied by 1000. • AplPp – as above, for Acer platanoides. • ApsPp as above, for Acer pseudoplatanus. • AglPp – as above, for Alnus glutinosa. • Bpepp – as above, for Betula pendula. • BpuPp – as above, for Betula pubescens. • CbePp – as above, for Carpinus betulus. • CsaPp – as above, for Castanea sativa. • CavPp – as above, for Corylus avellana. • CmoPp – as above, for Crataegus monogyna. • FsyPp – as above, for Fagus sylvatica. • FexPp – as above, for Fraxinus excelsior. • PtrPp – as above, for Populus tremula. • PavPp – as above, for Prunus avium. • PpaPp – as above, for Prunus padus. • PmePp – as above, for Pseudotsuga menziesii. • QpePp – as above, for Quercus petraea. • QroPp – as above, for Quercus robur. • ScaPp – as above, for Salix caprea. • SciPp – as above, for Salix cinerea. • SarPp – as above, for Sorbus aria. • TbaPp – as above, for Taxus baccata. • TcoPp – as above, for Tilia cordata. • UglPp – as above, for Ulmus glabra. • UprPp – as above, for Ulmus procera
