Whitebark Pine

A dead whitebark pine stands alone in an alpine meadow. Whitebark pine is considered a keystone species because of how many species rely on the cones it produces. This tree is one of thousands which have succumb to the recent mountain pine beetle epidemic. Over 80% of the stands in the Greater have dead trees in them.

Research has shown that a remarkable variety of species rely on the nutritious seeds produced by the pine cones. Red squirrels relentlessly harvest and cache the cones and seeds during the summer months. Shortly after, grizzly and black bears spend weeks raiding the cones from them. In 2009, a federal judge overruled an attempt to delist the grizzly bear, primarily on the basis of the decline in whitebark pine. The importance of these cones reaches far beyond bears and squirrels. Clark’s nutcrackers, chickadees, nuthatches, and woodpeckers are among the many others that rely on these seeds.

Red Fox in Grand Teton

There are few things I find more visually striking than a red fox against the white snow. I found this fox as it was hunting for rodents under the snow. The fox will listen carefully for movement under the snow, turning its head back and forth to pin point the sound before leaping into the air and diving head first into the snow.

Lodgepole Pine

Lodgepole pine dominates the Greater Yellowstone landscape. The drastically varying heights of the trees are a poignant reminder of a powerful force in the ecosystem, that of fire. This remaining stand of trees high above the Madison River has always impressed me. These few trees somehow survived while everything around them burned to the ground. Though we feel a sense of loss after a major burn, fire is not necessarily a bad thing, nor does it get the last say when it comes to these trees.

Lodgepole Pine

The lodgepole pine is equipped to respond to fire in a remarkable way. Their secret is found in a condition called serotiny. Now that we got the fancy word out of the way, what does it even mean? Many of the female cones produced by lodgepole pine remain closed, until they are met with the extreme heat of a fire, at which time the cones open and disperse seeds all over the forest floor. This is why you see such a high density of young trees growing in areas that have previously burned. The smaller trees pictured in the foreground here are 30 years old! They have a long way to go before reaching the heights of their forbears.

Yellowstone Fires

The lodgepole pine, making up 80% of the Yellowstone forest, is remarkably resilient in its ability to grow in less than ideal conditions. Here, the poor conditions eventually took their toll. The wet and mineral laden sulfuric soil around hydrothermal features is a tough place to survive. 

Yellowstone Thermal

These trees are known as bobby socks trees because of the white section on the lower trunk which resembles bobby socks. As the trees absorb the water from hydrothermal runoff they also take in minerals. When the water evaporates, the minerals remain and turn the bottom of the trees white.

In Search of Great Grey Owls

     It has been a challenging year for Great Grey Owls in the Tetons. With such a heavy snowfall, and repetitive thawing and freezing cycles, the snow pack was near impenetrable for these skilled hunters. Quite a few succumbed to the harsh conditions and were found dead. The ones that survived, managed to do just barely that, and did not have the strength to nest and raise chicks.

     On a typical year I spend a lot of my time with these owls. So much so that is easy to take it for granted. My search, going on three months, for just one good Great Grey image has really made me appreciate the time I’ve had with them in the past.

     After hearing about the appearance of one in the backcountry the other day, I dropped everything to investigate it. It took several hours of hiking, but just as the sun dropped behind the mountains I found the “Phantom of the North” hunting in an aspen grove. My time with her was brief, as darkness was enveloping the forest I still had to trek through to get back to the car, but I was reminded why I spend an inordinate amount of timing searching for just a moment with these birds.
