A Research Framework for the Archaeology of Wales

 

East and North East Wales Archaeological Resource Audit

 

Section 3:  Environmental Data

 

The following environmental data are derived from Cadw's Environmental Database for Wales (with six additional records derived from the SMR), curated by Astrid Caseldine of the University of Wales College Lampeter.  The summary table and map (arranged by the ‘primary’ period of their site of origin) are followed by lists of sites yielding environmental data supplied with the database. The list of C14 dates relates only to this environmental work - for other C14 dating see section 2. 

 

List of C14 dates from Palaeoenvironmental sites

The dates listed below are largely from pollen columns but a few dates arefrom deposits for which there is no associated pollen evidence.
