Over the past week, the amount of Juniperus ashei pollen in the atmosphere has been dropping. Over the last couple of days the surrounding communities, for the most part have recorded little if any of this pollen. With other spring pollen types in the atmosphere this is the signal to us that the Juniperus ashei Pollination season is over. There may be small amounts still released but they will be very localized and diluted by the other pollen types that area making it into the atmosphere. This is the last forecast for the season. Thank you for your interest in our work.
