A Good Year for Brilliant Autumn Colors?

Fall 2012... will this year be more colorful?
I've been surprised that we haven't had much in the way of a hard frost so far this year.  Yesterday, while driving back from Saratoga Apple (it's a good year for them!), and pondering the foliage, I got to thinking it should be a good year for brilliant colors.  Here's why...

What causes this phenomenon?
As for the primary cause, the Science Made Simple website posting Autumn Leaves and Fall Foliage: Why Do Leaves Fall Colors Change? explains "The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves"

Why are the colors more brilliant some years than others?
From the USDA Forest Service's Why Leaves Change Colors, "A succession of warm, sunny days and cool, crisp but not freezing nights seems to bring about the most spectacular color displays. During these days, lots of sugars are produced in the leaf but the cool nights and the gradual closing of veins going into the leaf prevent these sugars from moving out. These conditions-lots of sugar and lots of light-spur production of the brilliant anthocyanin pigments, which tint reds, purples, and crimson. Because carotenoids are always present in leaves, the yellow and gold colors remain fairly constant from year to year."

The exact opposite of what I had thought -- I had it in my head that the "good" years were caused by an early hard frost. According to this explanation, this should be a good year for brilliant colors.

From The Science of Color in Autumn Leaves (The United States Arboretum), "Temperature, sunlight, and soil moisture greatly influence the quality of the fall foliage display. Abundant sunlight and low temperatures after the time the abscission layer forms cause the chlorophyll to be destroyed more rapidly. Cool temperatures, particularly at night, combined with abundant sunlight, promote the formation of more anthocyanins. Freezing conditions destroy the machinery responsible for manufacturing anthocyanins, so early frost means an early end to colorful foliage. Drought stress during the growing season can sometimes trigger the early formation of the abscission layer, and leaves may drop before they have a chance to develop fall coloration. A growing season with ample moisture that is followed by a rather dry, cool, sunny autumn that is marked by warm days and cool but frostless nights provides the best weather conditions for development of the brightest fall colors. Lack of wind and rain in the autumn prolongs the display; wind or heavy rain may cause the leaves to be lost before they develop their full color potential."

Discover Your History

Click here to access this front page

I recently came across a website -- Old Fulton, New York Post Cards -- that will allow you to access over a hundred years worth of New York State newspapers.  Don't let the title fool you.  Yes, you can access images of old Fulton, New York post cards, but you can also access so much more. 

I was hunting down some history for my lake association when I quite literally stumbled on it. What's most amazing to me, as a librarian somewhat familiar with required skills and technology, is that it's all being done by one amazing individual, Tom Tryniski of Fulton, New York.  Click here to read about this guy, who apparently is disciplined, persistent, technologically literate and.... has a lot of time on his hands!

I've been able to answer the mystery of who changed our family's last name from from Maheu to Mayo.  I've also been able to dig out that article on the two doubles I hit off Bobby Leonard in 1966!  Sometimes, of course, history can be sobering, like the Berlin propane disaster in 1962 or, in my case, researching news on my grandfather who drowned in the Mohawk River when I was six-years-old -- not something my mother was comfortable in discussing.  History provides answers to questions, information and a way of making sense out of that information.  I applaud Tom Tryniski for making it possible for us to discover that history.

Red Alert!


How much development is too much?  Do Poestenkill residents want their bucolic town to turn into Clifton Park?  Do Rensselaer Plateau residents and visitors want New York State's fifth largest contiguous forest (118,000 acres) and a U.S. Forest Service Legacy Area threatened by 204 acres of development?  The 2010 census population of Poestenkill was 4,530 -- an increase of 12% from the 2000 census and, by far, the largest increase of townships on the Rensselaer Plateau.

Read up on the Planned Development District application submitted by JEM Company, Incorporated.  You have an opportunity to weigh in on this by addressing comments to the Town Board through the Supervisor by writing to:

Dominic Jacangelo, Town Supervisor
Poestenkill Town Hall
38 Davis Drive
Poestenkill, NY 12140

Alternatively, he can be e-mailed:  djacangelo@poestenkillny.com.  Public comments are due by September 19th.

From the application:
The parcel is 204.36 Acres in size. The parcel is bisected by Snake Hill Road with 72± Acres on the east side of Snake Hill Road and the balance of the parcel on the west side of Snake Hill Road. The majority of the parcel is wooded with mature upland deciduous forest. The parcel pitches both east and west to the low area centered between Snake Hill Road and Vosburg Road. This low area runs from north to south through the parcel and contains a serious of ponds, streams and jurisdictional wetlands.

Mushroom Day


My weather station indicated 100% humidity and a dew point reading of 70 degrees.  We just returned from a walk around the lake and I decided to take photos celebrating Mushroom Day....
