Archaeology
The description of peatlands as 'living history books' is
very apt as they can provide information about past landscapes,
climates and cultural activity, and highlight human impact
on the local and global environment.
Unlike mineral soils, which only preserve inorganic materials
such as stone axes and flints, peatlands have preserved a
wealth of organic materials including wooden tools and trackways,
clothing and jewellery, plant pollen and even animal and human
remains (Table 1). The degree of preservation
is influenced by many factors and so can vary greatly between
different types of peatland and indeed between sites.

Irish bogs have been cut for centuries and the archaeological
literature of the last 150 years shows a continuous record
of the discoveries made by turf cutters and others working
the land. The value of these artefacts recovered from peatlands
cannot be over-estimated.
Using pollen deposits in our peatlands, we can trace the
arrival of man in Ireland, the clearance of forests and the
planting of crops throughout history. Evidence that extinct
species such as the Giant
Irish Elk once roamed the Irish countryside has been discovered
in several bogs.
The archaeological value of peatlands is not just confined
to individual artefacts settlements, patterns of settlements,
field enclosures and tombs enable us to reconstruct the prehistoric
landscape.
