Small Mammal Response to Forest Succession 24 October 2013
An arboreal mouse of the genus Peromyscus...
Year thirteen of a small mammal community study with my Ecology students continues to go very well. We are looking very carefully at habitat use by a variety of small mammals in Polk County, Wisconsin. Safety protocol is very strict, and the mammals are measured, marked with permanent green dye (on the belly) and released. Short-tailed shrews remain a habitat generalist after all of these years. Meadow voles are only found in the brushy grasslands and beneath the low pine bows of our oldfield /early forest succession area. Red-backed voles remain a rodent of the tamarack and sphagnum bogs. But the mice of genus Peromyscus, formerly a rodent of the upland forest and bog lowland forest tracts of our school forest, are finally colonizing the oldfield/early forest succession area! The secret to this colonization is quite likely the size of the white pines, as many are now reaching 14 to 17 years of age. With their size they are providing plenty of arboreal structure and, recently, dead snags! We continue to see a variety of tail patterns in our Peromyscus, implying that they are hybrids, and while we could clearly call the population white-footed mice by their size, most have the tail pattern of the deer mouse. This population is very different in body size and body build than those of the Saint Croix River Valley in the same county! Surely, this species complex is still poorly understood!

Time passes. We are mere passengers and witnesses to its passing. Sometimes it rips by relentlessly and ruthlessly with no hope for stopping it. Runaway Train. Sometimes it flows slowly, mercifully, allowing the moments to sink in, allowing us great repose. We become authors of our lives, writing our stories but revising as time dictates. Time passes in so many ways as life moves along in lurches. This morning, in the rising sun, my own time stood still.

We are humans, gifted with thought and creativity, gifted in crafting our futures. The human memory is a powerful force, helping us to predict, with at least some certainty, the future. It is in our predictive powers that we meld our past, present and future, authoring the deeper details of our lives. We are very capable of making avenues toward "repeats." As we gather more and more memory in life, we become capable of revisiting annual events, chasing the seasons, improving upon what we have done before.

Sandhill Cranes, family group in flight. Wisconsin Sandhill Cranes have made a tremendous recovery and are becoming a common sight. Adults teach the young the migratory routes, and family groups are close-knit. Like people, families of Sandhill Cranes pass on a rich culture of learning.
We become capable of imagining a better opportunity, hypothesizing about the missing details. For those of us living as closely to nature as we can in this day and age, our predictive powers bring us to the same haunts year after year, chasing the same natural phenology, making opportunities and arriving at temporal intersections that we have come to understand. We hunt the patterns, and, as we learn from our mistakes, we adjust and improve. Our greatest power comes in the form of synthesis as we learn to incorporate smaller pieces of new knowledge into our older sets of knowledge, thriving in surprising and new scenarios.

In this way, I celebrate my aging mind and body. With more memories, I feel wiser. Simply said, I know how to find things now, how to create my opportunities. Everything in life is an experience. Every day is a treasure to be invested and to be used again as a memory. Every day is a treasure that builds possibilities for the future. Every day, lived in the moment, is a treasure.

These memories were made on October 13, 2013 at Crex Meadows State Wildlife Area. All images were made with a refurbished Canon 7D (now in my possession for nearly a year and surviving much), and a Canon 300mm f4 L IS lens. The bittern was completely unexpected and provided an unusual opportunity! As I chased the new season with my past experiences, I learned many new things!

All images were photographed on the same day, July 15, 2013. We awoke at Hacienda Baru and turned in for the evening at Savegre Reserve, Spa and Hotel. Many of the bird images were made as I saw and experienced the species for my first time! Pura Vida!
