What piqued your interest in conservation biology?
When I was doing research for Evidence of Evolution, which was published in 2009 to coincide with the 150th anniversary of Darwin publishing On the Origin of Species, that was a real deepening point. I was interviewing scientists at the California Academy of Sciences, and I heard over and over again from then that we were on a path to extinction. Scientists – sometimes in tears – spoke of the destruction of key natural sites, and the loss of biodiversity.
I really wanted to help these people. So for my next book, I was looking for a story that would help explain what was happening, but a good story with a hero and a quest. And I found a great one. That’s what became The Spine of the Continent. It’s an introduction to conservation biology and a profile of that field’s founder, Michael Soulé. He’s responsible for articulating one of the major tenets of conservation biology, “trophic cascade”, which refers to the chain of consequences when the top predator is removed from an ecosystem.
Another major idea, which drives all my writing, including what I write for Bay Nature, is connectivity. One way to describe connectivity is through the “corridor” concept. We can put our arms around a certain piece of land to protect it, but unless we preserve large, contiguous areas of land, many species will go extinct.
In describing The Spine of the Continent, you refer to scientific effort, social effort and geographical effort. What do you mean by the latter?
The “spine of the continent” is transnational; it’s the chain of mountains ranges extending from Canada to Mexico. The term “geographical effort” refers to the effort to coordinate work in different parts of the landscape along this spine. There are forty nonprofits working this concept of connectivity along the spine of the continent. They meet with each other periodically. Each knows that its work must connect with the others in order for all of them to succeed. It does not and cannot stop at a fence along the border between two nations. We’re looking at geography from the very big picture. It’s a big project, and it’s not complete. When I was reporting on it, I felt that it was moving way too slowly.
What is the remedy?
One answer is “citizen science,” which is regular people contributing to scientific research. I call it “grassroots meets big data.” My next book, Citizen Science: Searching for Heroes and Hope in the Age of Extinction, describes this. It explains how data can be collected, on cell phones for example, and then analyzed by scientists to make predictions and suggest actions. This process connects you and me to the natural world, as well as to the outcomes of scientific research.
Citizen science falls under the rubric of post-colonial co-creative research, in which the scientist is not isolated from the subject of study, is no longer an external but intrusive “authority.” Co-creation challenges notions of what science is, who does it, and how it happens. My upcoming piece in Bay Nature (April-June 2016) about the the recovery of traditional ecological knowledge by the Amah Mutsun tribe is another example of this.
What is your favorite outdoor destination in the Bay Area?
That’s such an impossible question . . . I’d have to say Hawk Hill in the Marin Headlands, near Sausalito. From there you can see Mt. Tamalpais, Mt. Diablo and Mt. Hamilton. The built human world looks incidental. You can get a magnificent view of the natural formation of the bay, and as the hawks fly by there is a sense of being part of their world.
Mary Ellen’s Wallace Stegner lecture “Citizen Science and Creating Better Wildlife Corridors”, hosted by Peninsula Open Space Trust (POST), took place at the Mountain View Center for Performing Arts on Tuesday, March 22 at 8 pm.
And don’t miss her article “Rekindling the Old Ways” on the Amah Mutsun tribe and the recovery of traditional ecological knowledge in Bay Nature’s April-June issue! Mary Ellen will be speaking on this topic at a forum entitled “Restoring Our Relations With Mother Earth”, on Thurs., April 14, at the David Brower Center, 2150 Allston Way in Berkeley. This event is sponsored by the Amah Mutsun Land Trust, Sempervirens Fund, and Bay Nature. For more information and tickets, click here.
