We are seeking observers to report when Ashe's juniper (aka mountain cedar, Juniperus ashei), trees are releasing allergenic pollen in Texas. Ashe's juniper is one of the most important causes of seasonal allergies in Texas. We don’t know yet how much pollen people are exposed to in their daily lives. If we were able to predict airborne pollen concentrations, we could warn people about pollen hotspots in advance and help people to maximize the benefits from their allergy medication. Your observations as part of this campaign will help to predict when people are exposed to this highly allergenic pollen. These data will lay the foundation for a regional pollen alert system for “cedar fever.”
