Nurse Log

Or stump actually. New trees often find the rotting corpses of dead trees to be a rich source of nutrients. Forest litter gathers in the niches and crevices of rotting wood, constantly adding more to the stew of decay that nourishes trees.

In this case, young trees are growing out of the stumps of trees harvested 70 years ago, so they are remnant stumps, not logs. The wet temperate rain forest along the north Oregon coast helps the stumps to break down at an accelerated rate. In this case, western hemlock seedlings gained purchase and grew to adult trees suckling on the dead stumps.

The result is rather sculptural, and I dragged some heavy duty studio lights into the forest so I could highlight some of the more interesting visual characteristics of the nurse logs.

Decaying trees are mini ecosystems unto themselves, providing shelter and food for fungi, lichen, small mammals, birds and untold populations of invertebrates. Below, a biologist holds the large larva of a giant root borer (Prionus californicus), which burrows through soft wood of various trees.



The stumps were photographed at property managed by the North Coast Land Conservancy not far from the Necanicum River on the northern Oregon Coast.

Foggy Coast, Haystack Rock

Passing through the Costal Mountains from Portland on the way to the beach on a recent morning, heavy fog had settled into the valleys.

Mist is a common occurrence in the coastal mountains, but usually as you get closer to the beach the wind coming in from the Pacific clears out the fog. But on this trip, I noticed the the rare absence of any breeze along the coast.

Haystack Rock, an old remnant basalt monolith that emerges from the surf near Cannon Beach, has been photographed about one hundred quadzillion times over the past century. However, it was such a rare atmosphere that it was a pleasure to hike out and capture a few images as the sun set.

Haystack Rock is designated a Marine Garden by the Oregon Division Of Fish and Wildlife above the high-tide line, and it is also part of the Oregon Island National Wildlife Refuge.

Bat Skeleton

I photographed this bat skeleton some time ago, but the image sat in my cataloging folder until I could get the post processing done.

Bats are such delicate creatures, and yet so beautifully put together. Their evolution is slowly being revealed by the fossil record and genetics.



I was hoping to illustrate the delicate nature of the skeleton, and yet show the dynamic flexibility of a flying mammal. I'm not so sure I was successful, and the tiny wing bones made the whole process very challenging. It will have to do for now.



This bat is a different species than the skeleton, but has a similar build. No matter what I tried, I could not come close to the elegance of a live flying bat that is shown here.
