Greetings!
We hope that you were not too adversely impacted by the recent storm! At long last, we've arrived at the end of the Juniperus ashei pollen season. Over the last two months, 46 of you observed 143 trees a total of 1,192 times at 61 different sites. That's a lot of data! These observations are already providing insight into where in Texas Juniperus ashei began releasing pollen early (like Kerrville and Austin) and areas where pollen was released relatively late this year (like Menard and San Antonio).
Based on our preliminary analyses, it appears that precipitation may be driving some of these patterns. As we delve into the data in the coming months, we'll keep you updated.
Thanks again for helping to collect the measurements that make this work possible!
Best,
Dan, Erin, and the Pollen Trackers team
PS- If you happen to have any eastern red cedar (Juniperus virginiana) in your area, we'd value any measurements on their pollen cones too! That species generally occurs to the east of I-35.
