Methods

Abundance: For point-frame, 1 if individual hit order data recorded, else sum of hits at that point (or plot, if only plot sums recorded). HEIGHT: Height from ground of a particular hit. Height was calculated only for coordinates with both a top and a bottom hit and estimated as the difference in heights between these two points.
