- Description
- This
set of preliminary, broad-scale vegetation/ecosystem map
reconstructions covers several time frames, the Last Glacial
Maximum (18,000 14C years ago), the early Holocene (8,000 14C years
ago), and the mid Holocene (5,000 14C years ago). For comparison,
'present-potential' maps that may be regarded as approximating the
late Holocene vegetation distribution as it would - or might - have
been without agricultural modification are included. The
reconstructions emphasize radiocarbon-dated evidence - whether
palynological, sedimentological or zoological and, while subject to
considerable speculation due to sparse data coverage in many areas,
they represent perhaps the nearest representation available to a
'consensus picture' as based on published review sources and advice
from approximately 100 specialists in all branches of the study of
Quaternary environments. The Atlas is divided into six regions,
Europe, Eurasia, Africa, Australasia, North America and South
America, each of which is accompanied by a detailed key of that
region's vegetation types, as well as a description of the
subregion's principal sources of paleovegetative evidence. The site
also covers the spatial resolution of the sites maps, geographical
boundaries in relation to climate transitions, no-analogue
vegetation types, and the prevalent uncertainties surrounding
various debates in paleovegetation and paleoclimatology.
