Cottonwoods: Where Wildlife Take Refuge In Winter

May 11, 2016

Thinking about plants in winter recently, I remembered a particular good-sized cottonwood I saw while walking along a riverbank. What was its story?

From James Halfpenny’s fascinating book “Winter:  An Ecological Handbook,” I learned that cottonwoods, like many northern trees, have very special adaptations to survive the long, cold winters. They begin their “hardening” process in the fall, as temperatures begin to drop and the amount of daylight decreases.  Leaves typically fall during this stage of hardening, but the process continues as winter settles in. 

'Field Notes': Bird Watching At The Polson Dump

Bird watching at the Polson dump is not for the faint of heart. The task requires an unnatural tolerance of gigantic machinery operated by large men wearing overalls and permanent looks of disapproval. But if you're serious about observing gulls, you need to go to where trucks discard trash at the edge of town. Evidently it's much easier for gulls to pick through our leftovers than to catch freshwater shrimp and fish.

Are You Mis-Using These Common Tree Terms?

Some write of “conifers and deciduous trees” as if they are somehow different. But, of course, when describing trees the words coniferous and deciduous may be distinctions without a difference.

As I split and stacked my winter firewood this fall in preparation for the long nights to come, trees in the surrounding forest were also preparing for winter. While I watched their leaves turning yellow along the flank of the Bitterroot Mountains, I found myself considering the confusing terms people use to describe those trees. In particular, folks tend to mix up perfectly good words in ways that leave me more befuddled than enlightened.

Two otters slip down a riverbank to merge with the cool depths of the Madison. An angler casts into a limpid pool. Nearby, a kingfisher plunges and emerges from the riffles, a minnow draped through its bill like a mustache. The profusion of wildlife in and around Montana’s blue-ribbon trout streams is no accident.

Although small and unobtrusive, an estimated 13,000 to 17,000 species of lichen spread across the Earth, from the Arctic to the equatorial tropics. One of those species, more noticeable than most, is Letharia vulpina, a brilliant fluorescent yellow-green, moss-like lichen that clings to the bark and wood of living and dead trees throughout the world, from sea level to timberline.

Humans tend to sense and respond to winter - the cold, the snow, the wind, the short days - by controlling their environment. We mediate winter's effect by living in a warm house, wearing thick jackets or flying like "snowbirds" south to warm and sunny climates. 

Do Bobcats Kill Deer? 'Field Notes' Investigates

Bobcats are relatively common in patchy habitats all across the U.S., but we don’t see them often because they are crepuscular or nocturnal and well camouflaged. But after a recent bobcat sighting, I'll be on the lookout for bobcats much more than I have before.

'Field Notes': Meeting A Montana Loon In Mexico

Each week the haunting wail of the common look opens Field Notes. The loon's cry always brings to my mind large, clear mountain lakes rimmed by lush coniferous forests, a handsome pair in their formal back and white courting plumage calling across the quiet water.

At no other time is the parting of clouds felt more powerfully than outdoors, at the height of winter.

Townsend's Solitaire: Soundtrack To Your Hike

When I feel the need to escape from town and immerse myself in the woods, I head up to Marshall Canyon, just east of Missoula, for a hike. Hiking along one of the old roads through the woods and taking in the fresh air and the views down the Clark Fork River towards Milltown soothe my soul and put things back into perspective. As I hike, I frequently hear what sounds like the squeak of a playground swing, swinging back and forth. This sound, however, is completely natural, the call of a somewhat drab-looking bird: a Townsend’s Solitaire.
