The Broadleaf Papers

The Broadleaf Papers

Trees have stories to tell, their annual growth rings cataloging changes in the environment, including climate. Many tree-ring scientists focus on conifers, but Neil Pederson, a scientist at Lamont-Doherty Earth Observatory, believes that the less-studied broadleaf trees in temperate forests, such as magnolia, tulip-poplar, maple and birch, have much to teach us.

What’s a tree like you doing in a place like this? Or West meets East

In the northeastern part of Turkey, the highest Pontic Mountains meet the Black Sea. Here altitude drops from more than 3900m to sea level in a less than 30 miles. Both the orographic effect of mountains and the lake effect (well, better sea effect) cause very high precipitation allowing for rich and productive temperate forest to grow.

Tree-Ring Science in a Log Yard?

The cool, snowy weather really put a crimp in our plans. Dario, Tuncay, Cengis, and others spent two days trying to find potential sampling locations before Nesibe and I arrived. Even though it had been well above freezing during the day and above freezing at night, the snow had only retreated so far in the [...]

Maybe not the Turkey you imagine

This Oriental beech is 164 centimeters in diameter (5 feet)

Despite reading about these temperate rainforests, this is not the Turkey I imagined. This might not be the Turkey most people imagine. I’m really not sure what you envision when you think about Turkey. A dry, open landscape? That is what I thought.

I have been very fortunate lately. In the last 6 months I visited forests I have longed dreamed about and visited forests I had never dreamed of before. I have been so fortunate that it is hard to believe. And, it is only going to get better in the next two weeks. Early in my [...]

Charismatic Megaflora: What do Old Trees Look Like?

Charismatic megaflora? What kind of a tree might that be? As with many things, one person’s charismatic megaflora is another person’s tree. For myself, a tree that would draw and hold my attention as a younger person/student is very different than my current definition of a charismatic tree.

Year without a winter?

No, of course not. Do not suggest anything like that to Alaskans, or Europeans where hundreds have died, or Inner Mongolians, or Koreans. But, turning the clock back to December and January for the New York City region, it was not apparent that winter would arrive as it ‘normally’ does. Yes, we have had significant [...]

The good ‘ol forest growth curve [update]

While the New Jersey bill failed, it is going to be discussed in New Jersey’s Senate Environment Committee on Monday, January 30, 2012. The discussion is not yet over regarding New Jersey’s public forests. The discussion about ecosystem productivity over time also continues in the forum of the Native Tree Society. Specifically, this post was picked [...]

Arboreally Speaking, the ‘Good Old Growth Curve Is a Delusion’

Tree Rings to the Rescue! Image: Neil Pederson

In the previous post, I outlined the argument lighting up parts of the New Jersey legislature and the human elements of its ecological communities. Briefly, one reason some people are using to promote logging on public lands is the perception that old trees and forests are dying of old age. While there are other arguments [...]

Arboreally Speaking, does age matter?

“There is unrest in the forest, there is trouble with the trees“…I will mostly spare you one of the more ecologically correct, forest ecology rock tunes (the next two lines, however, “For the maples want more sunlight, and the oaks ignore their pleas,” written in 1978, seem incredibly prescient given that one of the first [...]

Nature & Naturalists, an Ode to Adirondack Color

There was a nice article in the NY Times on the Adirondack State Park whose title initially focused readers on how climate change could alter the park’s ecosystems. However, by the time you get to the end of the article, and luckily for us, you get to know Jerry Jenkins, one of the best naturalists [...]
