Juniperus ashei

Currently we are studying the pollination ecology of Juniperus ashei (mountain cedar/Ashe juniper) trees in order to provide more accurate pollen forecasts. We are trying to determine the status of pollen cone development throughout the range of mountain cedar/Ashe juniper trees and are looking for volunteers who will help by checking the trees in your local area. The National Phenology Network (NPN) is working with us in this part of the study. If you would be interested in helping with our current research project, please click on this link to the NPN. If you have any questions, contact Estelle Levetin at
