New England in the fall is beautiful.
As autumn鈥檚 crisp chill fills the air, forests don a blanket of vibrant reds, oranges and yellows 鈥� seemingly preparing themselves against the upcoming harsh winter.
It鈥檚 a biological masterpiece, one fueled by innumerable tiny leaves combining to transform the landscape into a tapestry of natural artistry that attracts visitors worldwide.
I grew up in 黑料吃瓜网, so I take the season for granted. But fall here really is special. And the question was recently presented to me: Why, exactly, is autumn in New England so vibrant?
To find out, I took a hike.
I ventured into a forest in northeastern 黑料吃瓜网 with two UConn tree experts. We met up at Horsebarn Hill, one of the best viewpoints in the state, surveying a rolling river valley showing off with fall colors.
We see oaks just starting to turn red. Nearby hickories provide a dash of yellow 鈥� and, of course, the maples are already stealing the show, even on a cloudy day.
Here鈥檚 what I found out:
Our trees are diverse
One reason the foliage is so good is simply due to the number of species we have.
鈥淲e have a very diverse hardwood forest in this part of New England,鈥� said Bob Fahey, an associate professor and forest ecologist at UConn. 鈥淲e have both species that are more southern species and also some of the more northern species.鈥�
鈥淚n comparison to say, the Mid-Atlantic or other places that have lots of deciduous species, we have maples, which are just the best,鈥� he said.
鈥淲e also have a number of species that have nice yellow foliage,鈥� he said. 鈥淏irches and beech. If you go a little bit farther south from here, mostly what you have is oaks. And oaks can have good fall foliage colors, but there are a lot of times they don't and they don't last for as long.鈥�
We have lots and lots of trees
The diversity of species provides a diversity of color, said Tom Worthley, an associate extension professor and a forester at UConn.
He asked me to remember the last time I flew over 黑料吃瓜网. What did you see, he asked. Lots of trees, right?
鈥淢ost of the ground is covered by a tree canopy,鈥� Worthley said, noting that some estimates put that tree canopy cover at around 75% of the land area of the whole state.
鈥淏ack where we were standing a few minutes ago, we had some cherry trees,鈥� Worthley said, his eyes scanning the trees enveloping us. 鈥淭here's a few remnant ash, there's some walnut around the edges here. And let's see, some hickory.鈥�
A walnut tree towers over us 鈥� and there are even some white pines.
It鈥檚 that varied bioscape that sets New England forests apart.
鈥淓ven in my two-acre forest behind my house, I have 22 different species of tree, which is more than some regions of the northern part of the U.S.,鈥� Fahey said.
Travel to the west, and what you鈥檙e likely to see are lots of evergreens and aspen trees.
鈥淣ot that there aren't others, there are plenty of others, but not in the same abundance and not in the same kind of mix that we have around here,鈥� Worthley said.
Climate plays a role
Across New England are rolling hills with microclimates that can contribute to vibrant fall colors.
鈥淵ou鈥檒l see ... highly different color in different parts of the landscape, which has to do with temperature differences,鈥� Fahey said.
Combine that with 黑料吃瓜网鈥檚 mix of southern and northern species and the colors here might not be as exciting and bright as what you would see in Vermont and New Hampshire, Fahey said. But our foliage season can sometimes last a little bit longer.
One reason? Oaks.
鈥淲e have so much more of that oak component,鈥� Fahey said. 鈥淭he oaks will hold their leaves until the end of October.鈥�
Moisture, temperature and the amount of daylight all contribute to how long it takes for a tree to shed its leaves. And, for each species, the calculation is different.
鈥淎 tree makes an economic decision,鈥� Worthley said. 鈥淚t decides, 鈥榃ell, it's costing more in energy to keep these leaves going than what they're producing for me and so it's time to shut them off.鈥欌��
Why do leaves fall anyway?
It鈥檚 when leaves are green that the most important work is happening, pulling carbon out of the atmosphere and giving us oxygen.
And for that green color, we can thank the pigment chlorophyll.
鈥淭he color that's in the leaves 鈥� is always there from the time the leaf is grown,鈥� Worthley said.
鈥淎s the growing season fades, the chlorophyll disappears,鈥� he said.
Then the other colors in the leaf can begin to show off.
Pigments like anthocyanins (reds and purples) and carotenoids (yellows and oranges) peek out, tiny threads in an autumnal blanket transforming New England鈥檚 green forests into a richly colored landscape.
But why does the chlorophyll fade in the first place? It all comes down to nitrogen.
鈥淚t uses a lot of nitrogen to produce chlorophyll,鈥� Fahey said. 鈥淭rees want to hold onto that nitrogen.鈥�
So, he says, trees will absorb the nitrogen before they let the leaves fall on the ground.
鈥淣itrogen is generally the most limiting macronutrient in forests,鈥� Fahey said. 鈥淚t's the hardest thing for trees to get.鈥�
And while trees can use their roots to absorb nitrogen left in the leaves that do fall, other plants can get at that valuable resource, too.
So it鈥檚 better for a tree to keep those nutrients in house before offering a free buffet to nearby competitors.
Will climate change affect fall colors?
This summer was extremely wet, but recent summers in parts of the region have been marked by drought and extreme dryness.
That ping-pong of moisture and temperature extremes can stress forests, Fahey said.
鈥淎ll of these fluctuations in weather that are associated with global climate change do have a strong impact on trees,鈥� Fahey said. 鈥淥n the survival of trees, but also on the health of trees, which has a big effect on how colorful those trees are in the fall.鈥�
And because we don鈥檛 know exactly what鈥檚 going to come with the changes in the climate, we should be hedging our bets, Worthley said.
鈥淭he diversity of the forest, from a species standpoint, gives us a more potentially resilient forest,鈥� he said.
But in addition to species diversity, forests need structural diversity 鈥� meaning trees of different sizes and shapes 鈥� as well as age-class diversity.
鈥淲e need young trees. We need old trees. We need trees in between. Because everything changes,鈥� Worthley said. 鈥淭he more diversity that we can have, the more resilient the forest will be to whatever changes come our way.鈥�
