Grateful for @koshersoul.bsky.social's words about #WhenTreesTestify:
"We have been waiting for this. A botanical memoir, a history, a history with a Black lens-that takes us from roots to branches...an electric, bold weaving of ethnobotany, personal memoir, spirit and science and I am here for it"

Picture of book "When Trees Testify" with text that reads: "We have been waiting for this. A botanical memoir, a history, a history with a Black lens-that takes us from roots to branches giving us the keys to an alternative retelling of the American landscape and the ways plants mark who we are and where we've been. This is an electric, bold weaving of ethnobotany, personal memoir, spirit and science and I am here for it."

Grateful to spend two days on the Klamath watching chinook, liberated by dam removal, return to streams from which they’d been precluded since the Titanic sank. Fish are everywhere, in numbers that stagger the mind & locations that biologists figured would take years to repopulate. Too beautiful.

Most major theories in ecology assume some sort of equilibrium, but only ~half of empirical tests acknowledge it & even fewer observed it in their system. Does this matter? How did the idea become so pervasive in ecology anyway? Find out in our new paper! onlinelibrary.wiley.com/doi/10.1111/...

The Equilibrium Conundrum

Although an assumption of equilibrium dynamics underlies most ecological theory, the evidence for this dynamic in nature and in empirical studies is scarce. This creates an unfortunate disconnect bet...

Because I enjoy SciComm, I offer public talks and tree-ring workshops. The two-day tree-ring workshops include opportunities to interpret and then synthesize information gleaned from each tree as a class.

If either of these activities fit your institution or communities, please reach out.

Professional Update:
Starting January 2026 I will begin my two-year Highstead Research Affiliate position at Highstead: highstead.net.

Among other activities, I will begin a new project identifying and mapping old-growth forests in Connecticut, the Catskills, and Adirondacks.

I don’t know how much it might be out of the norm, but up here, a bit west pf Boston, a noticeable number of Red Maple kept their leaves until rather recently, some turning nice colors. It felt quite late (but was beautiful)

Then, we ran a simulation for a megadrought in 2070 and nary got a vegetation response. A hot, multi-annual drought will do nothing? Hard to fathom.

Then, @dendroecologist.bsky.social realized the soil component might be holding too much water.

Neil Pederson @yellowbuckeye.bsky.social · 18d

Are you talking about forecasts of the future? If so, when I first got a look at rainfall used for future simulations in the NE US, I was stunned. Just white noise with a slight trend. It is so much more dynamic, and then the oncoming heat.

The second points out a trend in dry late-summer soils in a climate of increasing large rainfall events.

To me, this might signal climate change as starting to negatively impact/overcome the 500-year upward wetting trend

Climate change and mosquitoes…

In early October 2023, we experienced 80-90F degree days and MOSQUITOES! in the Adirondack State Park. Growing up, I can hardly remember them there past July. No doubt some existed late summer back then, but not a lot and not in October.
