A new Symbol of Vernon the Florida Alligator

The Hermit Thrush has been an official symbol of Vermont since 1941 when naturalists prevailed over legislators who were divided between the crow and blue jay. Naturalists versus politicians, now there is an argument that we can all relate to during election season. While I like the intelligent glossy black crow and alarmist blue jay, the hermit thrush with its strong defense of "home" seems to have been a fine choice for these Green Mountains. Stable in population, these seasonal birds adapt well to a variety of forested lands and woodland edges, nesting low to the ground near sources of water. All of this seems promising for a novice like myself to cross paths with Hermit Thrush; and yet this is the first one that I have seen up close in my many in years of hiking the woods and swamps of Vernon.

Imagine my pause as I stepped onto our deck and spied the brown bird lying beneath our window. Perhaps a Walmart sparrow (European House sparrow) should have fist come to mind; but I wondered if I was looking at brown oak leaves blown over from Jim's collection. I suppose it must have been denial at first glance. What after all, are the chances that such a bird would still be hanging around in Vernon on Halloween day, even if it is just shy of eighty degrees out? 

I can't be sure of why this little bird died; and while I do have my suspicions, I think its important to note that: in addition to natural causes like predation and disease,  building collisions kill more than a billion birds in the U.S. each year.-American Bird Conservancy and outdoor cats kill around 2.4 billion birds- Cats indoors. Habitat loss, climate change, human wildlife conflict and environmental toxins are also contributors to bird mortality. 

Survival by Degrees is an interactive publication by the Audubon Society where readers can explore how climate change will affect the vulnerability of  birds by state as well as Mexico and Canada. This article lists Vermont as having 42 highly vulnerable species, 52 moderately vulnerable, 29 with low vulnerability and 45 stable species. Select your favorite bird and the site takes you to specific information on it. While I should feel a certain measure of comfort that the scrappy adaptive Hermit thrush rates in the least concern category, it doesn't escape my attention that he was on the verge of overstaying his seasonal residency while Vernon achieved record temperatures for October.  

 

A neighbor stopped to chat with me on my walk this afternoon and while we caught up, Esther kept nosing at her hand which held another adaptive species and our state flower, the VT red clover. Peak blooming in VT is in May and June with late September being on the outer edge of its blooming season.

Lorien's find got me to thinking about the purple lilac that Wayne's grandmother divided from her own heritage bush in 1991. We planted it at our first home in Hinsdale and then brought a piece of it to Vernon when we moved here. This spring it bloomed beautifully before losing all of its leaves by August. In late September its leaves started to bud out again. In October, we have had frosts, our first snow flurries, temperatures in the upper 70s and a blooming lilac. 

The trees are mostly bare, with the exception of a sugar maple out back. Red fruit adorns our viburnums, hollies and crabapple; but our hollies are also sporadically blooming along with blackberries, rudbeckia and sedum This just seems odd, but its not the first time in recent years that the seasons seem a bit catawampus.

Unlike more generalist species such as the hermit thrush and red clover, our state tree the sugar maple is a specialist . With Vernon being the south eastern most town in Vermont and "Vermont being among the fastest warming states" and with syrup production being frost driven, Vernon's maple syrup revenue is in jeopardy. Audubon Vermont has published a comprehensive easy to understand explanation of the impact of Climate Change on maples and the maple syrup industry The End Of Maple? 


November 1st with temperatures in the 70s

Today as Wayne and I were traveling through Westminster, we decided to visit the wetlands behind Allen Brothers. Typically when we stop at Allen Brothers, it is to browse their nursery stock searching for bargains on native plants; but the flowers, shrubs and trees are long since depleted in September. 

 Here in the pond on the very outside of their traditional start of brumation, we found another Vermont symbol, the Painted turtle. If turtles basking on logs in November isn't weird enough, a large frog hopped across the dirt road traveling between ponds while a dragonfly rested on my arm. 

In 2019, Iowa State University published research by Biologist Nicole Valenzuela. The article, Climate change could devastate painted Turtles,  notes that,  "Painted turtles undergo temperature -dependent sex determination while developing inside the egg. Eggs exposed to warmer temperatures tend to produce females, while cooler temperatures tend to produce males.


The publication further explains that with wider temperature swings, turtles and other amphibians may experience population collapse due to unbalanced female to male ratios.

November 2nd, with high temperatures in the 50 and lows in the 20s

In addition to my regular Vernon Conservation Commission meetings, I have been attending a lot of other meetings: CT River Conservancy meetings on dam relicensing, Vernon Hazard Mitigation planning, Vermont Environmental law implementation planning for Act 59, Basin 12 / Deerfield Watershed clean water planning, and most recently Reconnecting the Green Mountains: A multi-pronged approach for enabling wildlife movement hosted by VT Conservation Planner Jens Hilke and Biologist for the Vermont Agency of Transportation Jessie Johnson.

With each meeting I attended, the notion kept coming back to me that each of these projects are seemingly operating in isolation  and yet they were assuredly interconnected, the same in a sense as gazing at a brown object on my deck, my brain trying to make sense of it, the mystery of what I am looking at, what brings it to my backyard, how it fits into what I experience and know and then contemplating how it is I was going to interact with it. Is it any wonder I don't seep soundly at night?

I'm not super human or anything, just an overly curious well meaning volunteer who drifts off at meetings like the rest of you. My notes from Hilke and Johnson's meeting reads something like this: connected, connectivity, Bio Finder, movement west to east & south to north, connectivity scale, wildlife movement, climate change, NE pinch point, barrier effect, gene flow restriction, NRI, expand to connect, land use planning, transportation component...

As you can see, I take very detailed self explanatory notes; but my big takeaway is the moving map of points of light showing wildlife migration as they sweep across North America in a wide swath from west and south. These points of light and bands are growing more narrow and become more concentrated as they squeeze through NE. Vermont funnels migratory animals up into Canada where they are greeted with predominantly agricultural treeless lands.

And here my friends is the other shoe you have been so patiently waiting to hear drop.  Climate change with it's rising temperatures is causing wildlife's traditional ranges to expand northerly at a rate of one mile per year. This means that long time Vernon Vermonters who traditionally scorn everything Massachusetts, are already living in a Massachusetts climate. Invasive species that out compete and damage our native wildlife are surviving our warmer winters and our  native wildlife vulnerable to climate change must move northerly if they are going to survive. In their way are, fragmented wetlands, fragmented forestlands, man's infrastructure, ever decreasing recourses and dwindling genetic diversity.
