Tree Torture Labs

Two visually striking experiments are attempting to find out how trees will respond to climate change:  Sevilleta LTER, and Aspen FACE at Michigan Technological University. These science experiments invoke several recent landscape architecture projects, but are purely functional.

Sevilleta LTER

But we have to kill the trees to understand how they die. Not a lot of them, just a few.”  “We need to understand the mechanistic side if we’re going to model the effects of climate on a large scale, we need to understand why and where trees die. When we can do that accurately, we’ll have a shot at knowing the broader effects.– Nate McDowell

The experiments at Sevilleta focus on Pinon-Juniper woodlands of New Mexico and are subject to several experiments by researchers from Los Alamos National Laboratory (U.S. Department of Energy, Office of Science’s Program for Ecosystem Research).

To observe the impact of higher temperatures, 18 trees are wrapped in 15′ tall plastic cylinders with heaters that keeps the temperature about 7 degrees warmer than ambient conditions to simulate the predicted climate of 2100.
