Fall is just around the corner! ๐The scientists track fall color and leaf drop based on phenological observations and sap flow. The Sycamore tree tends to drop its leaves (where you see a decrease in sap flow) in late October/early November. #fall#data
Solar radiation and precipitation are key drivers of sap flow in trees. In this composite graph you can see the Spruce and Sycamore trees reacting to changes in solar radiation and precipitation during the 2020 growing seasonโ๏ธโ๏ธ #DataAnalytics#DataScience#nature
Scientists can measure tree trunk expansion using a dendrometer. This graph shows Sycamore dendrometer data over several years. It grows about an inch every year with small fluctuations throughout in response to weather conditions.๐๐ณ #DataScience#DataAnalytics#nature#spring
Hello Twitter! I am slowly waking up from my winter slumber โ๏ธ Click on the link below to hear from an @MortonArboretum scientist talking about the sensors that will monitor my physiological status this growing season๐ณ https://t.co/wWyOc6nvIH

@TreeGuyLouie @MortonArboretum The drones do many things! One drone is equipped with LiDAR technology which creates accurate 3D models of trees. Scientists can use those models to analyze canopy structure and monitor growth.
@DarkFeyFanClub @MortonArboretum Yes, drones provide easy access to tall tree canopies. Drones can be equipped with various tools to do many jobs. For example, a leaf cutter can be attached to a drone and flown up to take a leaf sample from the very top of a tree. ๐ณ๐
Here is sap flow data from the Sycamore last month. We can see when there was a significant rain event and when the tree began dropping its leaves (early/mid November). The Sycamore is now dormant for the winter โ๏ธ #data#dataScientist#phenology#winter
The Bowhall Mapleโs average daily sap flow this month was ~3 cm/hr. Sap flow has dramatically slowed in the past few days as the final leaves fall and the tree goes into dormancy for the winter. ๐โ๏ธ #data#dataScientist#fall#weather#trees#foliage#phenology
Thank you to the Davey Resource Group - Utility Vegetation Management crew for stopping by last week! @DaveyTree ๐ณ My leaves are just beginning to change color ๐ #Tree#nature#fall#phenology
