x.square:	Number of the 5x5 m square, counted along the baseline of the plot.
y.square: 	Number of the 5x5 m square, counted perpendicularly to the baseline
		(each plot includes 50x2 squares).
topo:		f: floodplain, b: ‘bottomland’ (=poorly drained), c: cross country, r: ridge.
inclin: 	Inclination of the 5x5 m plot; 1: depression, 1: flat (slope <10°), 
		2: slope <30°, 3: slope ≥30°.
x.direct:	Compass direction of the baseline
can.ave: 	Height to the centre of the tree crowns above the plot (in metres).
can.max: 	Height of the tallest branches above the plot (in metres).
density: 	Density of the understory vegetation. o: open, s: sparse, d: dense
		h: herbaceous, l: vegetation dominated by lianas. In the analyses
