Harsh Conditions and Sheer Courage

THOUGH WE QUOTE wildlife scientists extensively in every issue of National Wildlife, we don’t always describe the lengths they go to in their efforts to collect data. Consider the researchers who study one of the nation’s largest seabird colonies in the Farallon Islands off California.

Battered constantly by high winds and huge waves, and with no source of freshwater, the barren islands are hard to visit and even more difficult to live on. But for decades, scientists have been braving these harsh conditions for months at a time to learn about the behavior and status of such species as tufted puffins and Cassin’s auklets—birds that most of us will never have an opportunity to see in the wild. And as this issue’s feature “Seabird Signals” explains, the lessons they’re learning could have important ramifications for all of us. “The seabirds’ food web appears to be unraveling, and the scientists suspect that global warming is at the heart of the problem,” reports author Doreen Cubie.

According to studies in the Farallones and elsewhere along the Pacific Coast, warming water temperatures may be reducing ocean productivity and a number of seabird species are having trouble finding enough food for their offspring. In some areas, the animals’ populations are plummeting. The birds, observes one scientist, “are shouting at us.” Turn to the article to find out why we should be listening.

In this issue you also can read about another researcher in California who goes to incredible lengths to study the diversity of life in a place where no one had ever traveled before: the crowns of coast redwood trees, more than 300 feet off the ground. To work at such heights, Humboldt State University botany professor Steve Sillett relies on ropes, athleticism and sheer courage—“an unimaginably dangerous feat,” observes writer David Lukas. To learn more, see Lukas’ article “Climbing into an Unexplored Frontier.”

Lukas’ text is accompanied by images made by Tim Laman, who had to go to extraordinary lengths himself to photograph the scientist. “I had done some tree climbing before, but never to heights like that,” says the Massachusetts-based photographer, who pulled himself up to the redwood canopy on a single, 300-foot length of rope that Sillett had rigged up. “It was certainly exciting,” adds Laman.

In the writing above, I noticed this commet:

"To work at such heights, Humboldt State University botany professor Steve Sillett relies on ropes, athleticism and sheer courage—“an unimaginably dangerous feat,” observes writer David Lukas."

The hazard in not really unimagineble.

But the greater danger probably lurks in trees that have not been climbed before.

As one that works with trees, I realized that driving can be dangerous too, as we don't quite know which intersection will deliver the next drunk driver, etc..

For this reason, I find the redwood climbing hazards to be more imaginable, than unimaginable.

By the way, if you have not seen photos of the trees they climb, this page below has images of several trees climbed by Steve Sillett:

You wrote about going to "great lengths". If anything is long, it's the ropes.

Actually, some of the most dangerous climbs are the first climbs, not knowing exactly what is above.

But Sillett's work is not too much different than that of thousands of arborists.

The gear is top of the line, and that gear is not dangerous.

Ever read a National Geographic article about some cowboy country guys that climbed extremely high back in Asia, but had never practiced on anything higher than 10' increments? They said that you can only go one section at a time, and that's how they practiced.

Sillett's work is like that. He goes up one foot at a time.

It's really not "unimaginably dangerous", except maybe to people unfamiliar with trees, climbing and forests.

I'm actually suprised that tree scientists have become so surprised about some of what is up there in the tallest redwoods. Last winter, I found a chunk of canopy soil below El Viejo del Norte in the Grove of Titans, with ferns on it. People should have taken notice of this long ago.

These are groves I've been to in-person:

And will be back to for video and photographs next month.

The reiterated limbs and fractals of Iluvatar can actually be seen from ground level. And it's nothing reserved to redwoods. Even apple trees reiterated themselves when topped for fruit production and residential pruning. Watersrpouts become little fractals of the parent tree.

Although quite a bit more can be researched up in the canopy, it's remarkable that so little was observed from the ground in the past decades. Even the small "bonsai-like" trees and shrubs growing overhead can be seen.

At least the enthusiasm has opened the door for more people to become interested.
