These are P. edulis pollen data from sedimentary records from seven sites located in alpine lakes from the Southern Rockies of North America. The records cover the last 11,000 cal yr BP and seem to show vegetation changes afecting P. edulis related with climate (ENSO) variability.

This dataset has been carefully reviewed and curated in accordance with PANGAEA's exceptionally high quality standards. However, due to discontinued communication from the authors' side, it did not receive the usual formal approval by the authors and therefore lacks final scientific validation.
