Search the Database
The database currently provides midden location, elevation, age, and plant taxa relative abundance data obtained from over 300 publications. The database currently includes information on 3200 individual midden samples, 3097 radiocarbon ages, and nearly 1900 plant taxa. Documentation is provided that allows each individual piece of data to be traced back to its source publication(s), allowing comparisons of data that have been published in multiple reports.
Relative abundance data for macrofossils can be viewed in their original published format or in a standardized format wherein original data have been rescaled onto a standard presence-absence scale.
