two members of the team's second tier, David Wilcove, a conservation biologist with the Wilderness Society, and Dennis Murphy, the director of Stanford University's Center for Conservation Biology, scribbled a diagram on a sheet of paper showing large blocks of forest habitat stair-stepping down the west side of the Cascades. Wilcove keeps a copy of the rough drawing in a file cabinet to this day and claims it was the genesis of the plan that finally emerged. Others on the team credit Noon, Verner, and Sandy Wilbur, a biologist with the Fish and Wildlife Service, as the first proponents of the big-reserve concept.
In any case, the idea stuck. The scientists finally took out their marking pens and drew enormous amoeba-shaped blobs across the map, ranging up to tens of thousands of acres in size. To lessen the impact on logging, they clustered these owl reserves around existing wilderness areas and national parks.
The reserves covered nearly 6 million acres, but they were not pristine reserves of old growth. They also encompassed clearcuts, young plantations, and 30-year-old forests that, left alone for a couple of centuries, might become suitable habitat for owls.
REACHING CONSENSUS
For weeks afterward the committee mulled this radical strategy, weighing it against less drastic alternatives. "We were groping in a sense," Noon recalled. "It was unprecedented. We had no model we could pull off the shelf." For scientists, Noon explained, the method by which conclusions are reached is all-important. "The process has to be dynamic. You have to work in an environment where people can challenge each other's ideas. You have to have an open mind."
Finally, he said, the scientists came up with a workable process. "We decided to couch the plan as a way to test hypotheses. People tried to disprove each other's theories. That's when people started to feel comfortable with the process. It was a tense time, but it was a healthy tension. We were searching."
Thomas recalls that the moment of truth came in late February of 1990. "The more we looked and the more we examined and the more we learned about the mathematical model, we recognized that [small reserves] wouldn't do it," he said. "On this particular night there was tremendous frustration, and pressure was building up. We twisted and we turned every direction we could think of to defeat our own hypothesis, and we finally said, 'No, that's the scientifically credible way to go.'"
Thomas polled his team. The vote was unanimous. "And I said, `We've crossed the Rubicon. The die is cast."
Meslow does not recall the "cross the Rubicon" statement. "Jack gets a bit theatrical," he said. "I'm sure he thinks he said it. Of all of us, he was the one who thought most globally about how this was going to be presented."
But Forsman remembers the feeling in the room. "We finally made a decision that this was what we were going to do, that it was the best
