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.

Everyone say hello to my tweeting tree friend from across the pond Bowie the Birch! 🇬🇧 Bowie tweets about soil quality how it effects the daily life of a birch tree. #data #DataScience #nature #england #SoilHealth #soil

Even on this chilly fall day my daily sap flow is steady at about 6cm/hr., and my leaves are still green. #fall #data #fallvibes #phenology

Happy October! 🍂 The Sycamore tree leaves are just beginning to change color, but the daily sap flow is still at a steady ~10cm/hr. #fall #trees #nature #phenology #data #DataScience #Weather #October #SpookySZN

Thank you to the Davey Resource Group - Utility Vegetation Management crew for stopping by last week! Davey Tree Expert Co 🌳 My leaves are just beginning to change color 🍂 #Tree #nature #fall #phenology

It has been a dry fall season 🍂 My weather station recorded 1.05 inches of rain so far this month. In October 2021, it recorded 7.05 inches of rain. #data #DataScientist #nature #phenology #fall #weather #October

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

Happy November! 🍂🦃 I am showing off my fall color on this rather warm day. My weather station read 71 degrees F this afternoon. On this day last year, it was 46 degrees F. #phenology #fall #November #weather #data #DataScience #climate #trees #nature

November me vs December me 🍂➡️❄️ American Forests #winter #fall #weather #phenology @USANPN Phenology News

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

Drones play a huge role in tree science and conservation. Are you curious about the drone program at The Morton Arboretum? Ask me questions! #drone #nature #conservation #technologies #STEM MortonArboretum

❄️Some tree species are vulnerable to injury during the winter. Read more about winter injury to trees and how you can help protect your trees❄️: mortonarb.org/plant-and-prot… #winter #weather #snow #WinterStorm #nature #snowstorm

It’s goal setting season! My goals for 2023 are to mitigate storm water, provide cleaner air, and store carbon! What are your 2023 goals? #iTREE i-Tree #nature #2023goals #2023NewYear #trees #Science #DataScience

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

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

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
