California Condor

by Lisa Eller, director of communications

As we turned another corner along the old coast Highway 1 between our campsite at Pfeiffer Big Sur State Park and Sand Dollar Beach, I looked out admiringly at the majestic scene, the Pacific Ocean crashing against the rugged coastline, framed by the Los Padres National Forest. I could look at this view all day. This stretch of road is one of my favorite drives and one of the most beautiful in the West.

Looking out at the fog rolling slowly by, my eyes began focusing on something unusual coming out of the whiteness. Enormous black wings gliding above us, casting a huge shadow below. I had never seen anything so big (and not manmade) in the sky before, so it took me several seconds to realize that I was probably seeing a California condor.

Growing up in Southern California in the early 80s, I never thought I would see the condor outside of captivity. The bird was a recurring topic of our natural history lessons in school. By 1987 the California condor had become extinct in the wild because of poaching, lead poisoning and habitat destruction. The 22 remaining wild and captive individuals were put into a captive breeding program by the U.S. government in an effort to save the species.

Beginning in 1991, condors were released back into the wild. But it wasn't until 2006 that a pair of released birds attempted to nest in a hollow tree near Big Sur. According to Sky News, that was the first time in 100 years that a pair of condors was seen nesting in Northern California. Click here for more information on the California condor.

My heart began racing immediately after I spotted the rare bird — although I didn't realize just how rare it was until doing some research later in our trip.

"That was a California condor," I told my husband, who was driving the car. Ever the skeptic, he insisted that what I had seen was probably a turkey vulture. "No, I don't think it was. Pull up over here," I said, pointing ahead. I wondered if we could catch another glimpse of the bird.

After he turned into a scenic point and stopped the car, a condor (probably the same one I had seen above) landed on the edge of the cliff in front of us. After getting an impossibly close look at the bird's impressive size, characteristic bald, gray/nude-colored head and the tag on its wing, we agreed that it was a condor. "Quick, take a photo!" I told my shocked husband. But it was too late. The bird took one look at us, stretched out its enormous, beautiful black wings and flew off into the fog.

Something about seeing the bird made me sad and hopeful all at once. It was sad to think how close we came to losing the species altogether, how small the population remains and how seeing condors in captivity pales in comparison to seeing them in the wild. Yet I couldn't shake the hopeful feeling that even when all seems lost, swift conservation actions can be taken to reverse the course and move us in the right direction. And to be clear, the condor is still critically endangered and we still have a lot of work to do.

This unforgettable experience made me think about birds that are meaningful to Idahoans and integral to its landscapes, birds like the long-billed curlew and Greater sage grouse. At varying levels, each of these species faces the same or similar threats that the condor does. Habitat loss through various human uses is a common thread. As an organization we could not possibly tackle all of these threats at once. But I am thankful that we are focused on that key piece of conserving, protecting and restoring habitat. And I'm thankful that we are part of a community of organizations focused on doing its part to ensure we all get a chance to see these majestic birds in the wild.

Cuba to Yellowstone

by Bob Unnasch director of science

During the past several weeks I had the opportunity to take a break and travel some. At the end of May I traveled to the Archipiélago de los Jardines de la Reina, a cluster of islands off the southern coast of Cuba. Two weeks later I spent a few days in Yellowstone. 

While honestly, the main reason for my visit to the Caribbean was to catch large fish on flies, I was also excited to see the island’s biodiversity. Cuba is only 90 miles south of Florida and 140 miles east of the Yucatán. At times the Gulf of Mexico Loop Current sweeps past the Yucatán peninsula and turns due east brushing the northern coast of Cuba. Other times the current flows north through the Gulf of Mexico then south along the western coast of Florida before flowing east through the Straits of Florida. It seems like the ideal conveyor to carry critters to the island. I anticipated the fauna of Cuba to be an amazing collection of North and Central American critters.

My trip to the Jardines involved flying into Havana and then driving ~300 miles to the small town of Júcaro. We then boarded a boat for a 60 mile trip to the islands. To my great disappointment I saw no mammals, nor any evidence of mammals. Similarly, I saw few bird species — even remarkably few individual birds. I was dumbfounded; my daydreams of a biologically diverse paradise, shattered. Maybe it was time to get my eyes checked.

Upon my return, I did a bit of research and discovered that it wasn’t my eyes. Cuba's native land mammals include two insectivores, one coney, and twelve rodents. Of these, five are extinct, including the coney, and five are critically endangered. By comparison, Yellowstone has 67 native mammals in the park, (Idaho has 107).

Our visit to Yellowstone National Park was a typical driving tour over a few days with a couple of stops at the Conservancy’s Flat Ranch. We saw all the charismatic mega-fauna that make Yellowstone famous and lots of small and medium mammals. It was fun, as always, to see the abundance and diversity of the park, and to imagine what the Rocky Mountains were like a millennium ago.

During my drive home, I started to think about the contrast between Yellowstone and Cuba. What would Yellowstone, or Idaho, be like if we only had a handful of native mammals? It would certainly feel different... and empty. Conservation biologists have described many tropical forest parks as suffering from an “empty forest syndrome”. The forests still have their trees, but all the large mammals are gone; typically the result of market hunting.

We are seeing dramatic changes in the Rocky Mountains. Warmer winters have released mountain pine beetles which are now decimating our forests. Our whitebark pines, which play a keystone role in these ecosystems is disappearing. Whitebark pine nuts are a crucial food resource for a diversity of animals, including the Clark’s nutcracker and grizzly bears. We don’t know what will happen when those pine nuts are no longer available. Climate change rather than market hunting may well be emptying our forests. While we cannot predict how the future will unfold, we can build on what we do know to hopefully minimize the impact of the changes we see coming.

Ecologists use the word niche as a catch-all term that means “all the biological, ecological, and physical constraints on a species’ range”. Physical constraints include climate, geology, soils, hydrology, etc.  In 2010, two TNC scientists, Mark Anderson and Charles Ferree proposed a unique strategy for biodiversity conservation in light of climate change. Rather than focus on the species, we should focus on maintaining those geophysical features that ultimately control species distributions. This idea has taken hold and the strategy is now called “Conserving Nature’s Stage”. Click here for more information.

TNC has embraced this idea and is now mapping the geophysical diversity (Nature’s Stage) across North America. We completed this assessment for the Pacific Northwest late last year, and are now identifying key areas for conservation. The Doris Duke Charitable Foundation recently granted The Nature Conservancy $6,000,000 for land conservation work within these areas.  I’m hopeful that by conserving the diverse ecological stage we’ll be able to ensure that the actors will always find a home.

Tree Hugger

by Valerie Connor board liaison/operations assistant 

Big, strong, dark and handsome.  I’m standing under a mighty Ponderosa Pine and it is my new favorite tree. The orange-brown color, the vanilla smell, and the puzzle-like texture of the bark are all so captivating. It’s the weekend and my husband and I are out exploring.  We end up outside of Featherville in the Baumgartner campground.  We set up camp beneath this pine, the canopy dense enough to create a circular open space at its base.

Over the weekend, we get to know this tree and its inhabitants. The first morning we watch western tanagers flying in and out of its branches, flights of yellow and red flashing overhead, their fluty calls making us smile- so cheerful and uplifting.  Later the nuthatches flew in and nimbly scurried around the trunk, excavating for insects.  Gray jays swooped in looking for handouts.

Pinus ponderosa is a long-lived, common tree throughout the western U.S. They are drought-tolerant trees with a thick protective bark that can withstand low-intensity fire and have a deep tap root. Old growth ponderosas can grow up to 180 feet tall and 4 feet in diameter. The cones are 3 to 6 inches long, and take two years to mature. The bark starts off dark brown and turns to orange-yellow at about 90 years of age. Ponderosa needles are bundled in threes and they are five to ten inches long.

Ponderosa Pine thrives from Canada to Mexico and from the Pacific Coast eastward to South Dakota, an area that stretches over more than 35 percent of the area of the United States.  They make good lumber and were mercilessly harvested over the course of a century of railroad building and development in the West. Concurrently, fire suppression became the defacto forest management policy. Over time, the buildup of flammable materials on the forest floor resulted in hotter fires that the trees were not designed to withstand.  The combination of these two factors quickly diminished the forests across the Western US.

The science of Forestry is well known, yet poor management practices persist today.  The Nature Conservancy is taking a stand for forests, offering resources, expertise, science and collaboration to help restore and protect our forests.  Find out more about our forest initiatives here. 

Back at the campground, we pack up. It rained overnight and the trees look vibrant in the morning light. The tanagers fly in, alight on a high branch and peer down at us.  We decide to stay just a few minutes longer and bask in the peaceful shade of the ponderosa.  I am drawn to this illustrious tree and when I wrap my arms around its trunk, I feel one with nature-just me, the ground and sky and my new favorite tree.
