    Tree Rings and Teachable Moments

    Nicole Davi, a postdoctoral scientist at the International Research Institute for Climate and Society and the Lamont Doherty Earth Observatory, thinks tree rings are an ideal way to motivate students to collect and analyze data as well as to learn about climate change.

    Finally – Some true Turkish Delight! Discovery of some tasty oaks

    After a few days of mild frustration, the sampling of potentially old umbrella pine lifted our spirits and put us in a good frame of mind to conduct our last day of research in the temperate rainforest region of northeastern Turkey. We headed out of Borçka and met with a forest officer in charge of forests…

    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…

    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…

    Around the Broadleaf World in 180 Days

    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?

    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’

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

    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…
