Thank you for your interest in our pollen forecasting web site. We have stopped the Mountain Cedar forecasts for 2013-2014. The mountain cedar trees in most areas have stopped pollinating. Also the spring tree pollen season typically begins February in Texas and Oklahoma. In Texas we are seeing some elm, ash, and alder pollen being reported by sampling stations. So it appears that the spring pollen season has started in some locations.
It is important to remember that mountain cedar and eastern red cedar are closely related species, and eastern red cedar begins pollinating in February. The pollen from these two species have been reported to cross react. As a result patients allergic to mountain cedar may continue experience symptoms for the next two months. However, eastern red cedar pollen is not considered as potent an allergen, so symptoms may be not as severe.
Check our Spring Pollen Pages for information on other pollen types. Although this was set up for eastern Oklahoma, most of the trees occur throughout the south central United States.
