We spent the day at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire, speaking with two researchers -- Elizabeth Studer and Laurel Symes -- about their work at the historic site for forest research. We spoke with Studer and Symes about the future of the ash tree and what will happen when ash goes extinct, bioacoustics and birdsong, what “biogeochemistry” is, and the history of research forests.
