abernethy: Abernethy Forest Pollen Sequence

Description

The classic pollen data set from Abernethy Forest in the Scottish highlands, UK. The data originate from the work of Hilary Birks and Rolf Mathewes (1978) and have been analysed in several texts on quantitative numerical palaeoecology.

The data set consists of 36 pollen taxa from 49 levels, with two additional variables; Age, the age of each sample, and Depth the depth (in cm) below the surface of the peat sequence from which the core was taken.
