Search the Database
The database currently provides midden location, elevation, age, and plant taxa relative abundance data obtained from over 240 publications. The database currently includes information on 2583 individual midden samples, 2834 radiocarbon ages, and nearly 1500 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.
