Bringing Lichens Down to Earth
Posted in Science on December 13 2012, by Jessi Allen
As a student studying lichens at the NYBG, Jessi Allen offers a unique perspective on these fascinating organisms–symbiotic combinations of fungus and algae. She first joined the NYBG as an Herbarium intern in the summer of 2011, and began her graduate studies this fall.
During Hurricane Sandy, many trees fell throughout the Garden. At least a few of those caused damage to buildings or left gaps in the landscape. However, the silver lining of this cloud came in the form of giving NYBG botanists a chance to collect data that we usually don’t have access to.
Of the trees that fell, one of them was a big oak near the Pfizer Lab that, luckily, landed in the parking lot. The day immediately following the storm, I was working in the lab and saw Mike Nee, one of our curators, climbing through the tangled branches taking cores from this tree, and I thought, “That looks like fun!” According to Mike, the tree was about 90 feet tall and close to 100 years old. Rarely are we able to collect lichens from the tops of such large trees, so I went and grabbed a hammer and chisel, common tools for collecting specimens.
