A Walk in the Woodland
By John Moores
90F temperatures couldn’t keep a dozen people away from Trustee Michelle Ruby’s entertaining and informative walking tour of two Groton Conservation Trust properties, on Sunday August 7, 2022. The tour passed through the West Throne Hill conservation property and continued to an 1800s-vintage house foundation on Lawrence Land. Both properties are wooded, with the canopy providing much appreciated shade on this hot day.
Along the way, Michelle described many of the local fauna, including sassafras (Sassafras albidum - white sassafras) readily recognizable with three very distinct leaf shapes with 1, 2, and 3 lobes; the diminutive American chestnut tree (Castanea dentata - toothed chestnut); and the species of tree with bark resembling “burnt potato chips” (black cherry, Prunus serotina). She also provided intriguing insights regarding both natural phenomena (e.g. why did this tree fall? Why do we still see small chestnut trees despite the ravages of the chestnut blight fungus?) and historical insights (e.g. why was the stone wall built, and why does it look different from another wall not far away? Why does this tree have wide branches while all of the other trees nearby in this section of forest are more vertically inclined?). The audience was clearly engaged, asking many questions throughout the journey.
Did you know that there is a nondestructive method to estimate the age of a tree? Michele demonstrated that with only a tape measure and knowledge of the tree species, one can use look-up tables to estimate age from diameter. To make the task even easier, she has specialized tape measures that gently attach to the tree, facilitating measurement by solo foresters. Furthermore, her tape measures conveniently scale the measurement by a factor of pi to directly convert circumference to diameter!
Susan Hughes, VP of the GCT, was also present on the tour, answering questions and offering her own insights. Not far from a vernal pool in Lawrence Land, Susan mentioned that everyone is invited to the GCT’s annual vernal pool tour in the early springtime. This is a popular hands-on (waders-on), exploratory family event with GCT Trustee guides. Susan also shared the excitement of the first-known discovery of marbled salamander larvae in Groton in 2018.
These are just a few of the many interesting topics packed into this 90 minute tour.
