Visualising Vegetation

I usually get lost in the wiggles and weird nomenclature of paleoclimate data papers and presentations. Most seem to require some magic eye or inner sight, that I am sadly not gifted with, to see the climate signal. All I usually see is “noise”. This figure, however, is beautifully informative to this non-expert of paleo-data. Perhaps such figures are old hat. I probably need to get less tl;dr. Even for this one, you have to get through 7 pages of weird wiggles before it appears, on page 8 of the 12 page paper.

  1. The abstract is at
    That helps make sense of this (for this amateur reader); the full text there is paywalled and Scholar doesn’t turn up any other copies.

    “The Holocene began with the expansion of Betula, Ulmus and Picea abies, followed by Fraxinus, Quercus, Tilia and Corylus avellana from about 10 000 cal a BP when the climate became warmer and drier. Picea abies has been the dominant tree species for almost the entire Holocene period. The spread of Carpinus betulus occurred at ca. 5800 cal a BP, with maximum values between 5100 and 3100 cal a BP, while Fagus sylvatica spread at ca. 3100 cal a BP and attained maximum values between 2800 and 200 cal a BP. However, during the last 200 years, Fagus sylvatica and Picea abies forests have largely been replaced by Pinus. Human impact in the area is noted from ca. 4200 cal a BP onwards but it is expressed rather weakly until 1200 cal a BP, and primarily relates to forest clearance and grazing….”
