Fall is just around the corner! 🍂The 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 season☀️☔️ #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.📈🌳 #DataScience#DataAnalytics#nature#spring
Hello Twitter! I am slowly waking up from my winter slumber ☀️ Click on the link below to hear from an @MortonArboretum scientist talking about the sensors that will monitor my physiological status this growing season🌳 m.youtube.com/watch?v=t5dhKY…
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 ❄️ #data#dataScientist#phenology#winter
The Bowhall Maple’s 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. 🍁❄️ #data#dataScientist#fall#weather#trees#foliage#phenology
Thank you to the Davey Resource Group - Utility Vegetation Management crew for stopping by last week! @DaveyTree 🌳 My leaves are just beginning to change color 🍂 #Tree#nature#fall#phenology
Good morning and happy first @MortonArboretum#PhenologyFriday of the fall cycle! Although we’re definitely still a ways away from peak fall plant-wise, now is when we amp up fall monitoring like leaf litter collection so we can really describe the temporal dynamics.
