Throughout the eastern United States, one of our most iconic forest trees is dying. Eastern hemlock (a.k.a. Tsuga canadensis; Figure 1) is being sucked to death by a small insect, the hemlock woolly adelgid (a.k.a. Adelges tsugae). As a scientist, I study how our forests may respond to the loss of this “foundation” tree species.[i] As a human being, I cry, I mourn, and I look to the future for hope.
To reconcile the desire for knowledge and the emotional tearing that affects many of us who study eastern hemlock and all of us who are living with these fading trees,[ii] I have partnered with two artists—David Buckley Borden and Salua Rivero—to develop Hemlock Hospice: a collaborative, field-based installation that blends science, art, and design that  respects eastern hemlock and its ecological role as a foundation forest species;  promotes an understanding of the adelgid; and  encourages empathetic conversations among all the sustainers of and caregivers for our forests—ecologists and artists, foresters and journalists, naturalists and citizens—while fostering social cohesion around ecological issues.
Starting today, and over the next several weeks, we’ll be installing Hemlock Hospice in and around the oldest stand of eastern hemlocks in the Prospect Hill Tract at Harvard Forest, and I’m using this space to keep track of its background and progress. I’ll also be presenting an overview of Hemlock Hospice in a five-minute “ignite” talk at the Annual Meeting of the Ecological Society of America in Portland Oregon, August 6-11, 2017.[iii]
I’m taking a day off from writing about my scientific and culinary adventures in China, and turning my attention to science and art. I spend a lot of time thinking about the relationship between science and art, but not in the way that it is mostly written and talked about, which is art drawing influence from science and technology, and reinterpreting it for different audiences. Rather, I’m particularly interested in how science and scientists – which in my case means ecology and ecologists – have been and continue to be influenced by art and the humanities in general. I’ve even written a couple of papers on the subject, which you can read elsewhere on this site.
But right now, I’m working with Carri LeRoy, a faculty member at the Evergreen State College in Washington State, to organize an “ignite” session for next summer’s Ecological Society of America meetings, to be held in Portland, Oregon. If you’re interested in this topic, and want to give a talk/presentation/exhibition or join the discussion, then…
After a final night in the city of Ya’an, Sichuan Province, we headed north back into Shaanxi Province, following the Bao Jiang (Bao River) towards Baoji. We were on a small, older road, but it is being replaced by the new Baohan Expressway. This superhighway will run 200 or so kilometers (at least 12o miles), and will have been built, start to finish, in about 3 years. According to Chen Dong, building a highway like this is considered an “easy” project: it follows an existing route (in this case, right up a riverbed; the existing road is built above the river on an old terrace), uses established precast concrete technology, and takes advantage of China’s immense and hungry labor force.
But I think that it marks the end of the road for the Qinling panda. The sign at left, overlooking a reservoir (photo below; ironically established as a national wetland reserve – once the lake behind the dam silts in, it should be a very nice wetland!), reads: 熊猫故里 (xióng māo gù lĭ), literally the “hometown” of the panda, but idiomatically meaning “pandas once lived here [in this their native home], but they don’t anymore.”
We had hoped to get to the Wolong Panda Reserve, but the roads, damaged by the 12.V.2008 Wenchuan earthquake (mganitude 8.0) and more recently by heavy rains and flooding, were not passable. We re-routed to Beichuan, which was the city closest to the epicenter of the earthquake, the ruins of which have been left standing as a memorial to the >87,000 people who died and > 15,000,000 who were displaced and relocated.
We did pass through what had been panda reserve lands, but which now, more than eight years after the earthquake, have few, if any, pandas remaining. All the pandas that had been at the Wolong breeding center were relocated after the earthquake to Chengdu (see yesterday’s post, below).
