On Our Western Juniper Survey in Redmond’s Dry Canyon

Leave a reply

This is an explanation of the importance of the survey work being done by the Friends of North Dry Canyon Natural Area, FNDCNA, and it’s role in the creation of a broader management plan, and a fire management plan, that addresses both community safety needs, as well as those of the Western Juniper and Sagebrush steppe plant communities in Dry Canyon. This is a 160 acre portion of the Canyon Park that stretches 3.7 miles, north to south, through the City, a remnant of one of the canyons formed by one of the previous courses of the paleo-Deschutes River, (There were at least two, one some distance east of Redmond’s location, joining with the Crooked River at present day Smith Rock State Park. The current Deschutes River flows 4 miles to the west of this location through a canyon carved in its earlier stages by Tumalo Creek.) Continue reading →

On Biology, Ecology, Evolution: Health as a Product of an Engaged Life Aided by Science

Leave a reply

Biology, the ‘life sciences’, botany, evolution, cell biology, ecology, health and disease, plant communities, our relationship as humans with each other, geology and the life around us, are all topics that interest me. My most recent reading choices have focused on embryology and an organism’s capacity to maintain homeostasis, what is meant by ‘health’. Earlier I focused on the big question of ‘What is life?’ I’m an integrator, an intuitor, an assembler of conceptual puzzles. For me understanding is the goal and that usually involves understanding the ‘pieces’ of the puzzle and fitting them together into coherent wholes. That’s what I do when I select books and read. While my fiction choices are relatively wide and varied, when it comes to this question, I am far more focused, purposeful. I am not overly concerned with being correct in terms of conventional thought or even regarding that which is accepted as being scientifically correct. I’m looking for what makes ‘sense’. I ‘test’ what I read.

Science is conservative and rightly so. It works to define a foundation from which we may build on. Many, if not all scientific advances, came at the expense and pain of researchers who reach beyond the established to address the problems that accepted theory has revealed as the process advances. Egos and careers can get crushed. Arguably, every significant advance in science began as a controversial idea. Over time, with repeated experimentation, advances in technologies that enable scientists to address questions not previously possible, new insights and ways to ask the ‘question’, the new gains support, or alternatively, is revealed to be ‘wrong’. In this process other questions arise, that move us toward a more complete ‘truth’, a truth that enlightening and revealing, can never be the ultimate answer. What preceded it was not necessarily ‘wrong’, but more likely incomplete, unable to fully explain the world as our understanding of it itself changes. Science becomes a process of understanding at an ever finer scale. What once served, still does, but in a coarser grained way. Occasionally, it demands a radical rethink of our basic understanding of reality. Continue reading →

Everything is Tuberculosis: a Disease as an Object Lesson On How to Better Live Our Lives

Leave a reply


John Green’s, ‘Everything is Tuberculosis’ is a great piece of writing. It is also an excellent, expansive and accessible introduction to the world of tuberculosis. By number, it’s the world’s most deadly disease, but one that is often overlooked by those of us in the wealthier, western countries, where it is largely controlled. This is a history of the human experience and the way that we have gone about treating it, or not. Tuberculosis (TB), is a disease that was an undeniable fact of life around the world for the majority of ‘modern’ human existence, before germ theory and our ability to develop and implement effective treatments. There was literally no place in the world ‘untouched’ by it. It killed indiscriminately. Author Green, mostly known for his young adult fiction, tackling problems of teen angst, love, loss and grief, here goes beyond this, asking the question, that since TB is treatable and curable today, generally even those forms that have developed resistance to several of the drugs used to control it, why is it still killing 1.25 MILLION people around the world every year? The answer isn’t difficult to find, but it reveals an ugly fact of modern life. The disease still kills to the degree that it does today because of prejudice, poverty, underfunded health care systems, a misguided reliance on cost ‘effectiveness’ when deciding who is ‘worth’ treating and a pharmaceutical industry far more interested in protecting and increasing its profits than it is in working to bring about a healthier world.

I Contain Multitudes: An Excellent Starting Point for the Beginner to Understand this Life

Leave a reply

Ed Yong’s, “I Contain Multitudes” takes a different angle into the biology of organisms, looking not so much at the functioning of the individual as it does those countless single celled organisms, protists and tiny ‘critters’ that live within and upon us, bacteria, fungi, nematodes, viruses, dust mites etc. There are bacteria living within larger, multi-celled organisms with viruses living inside these….And these are not unusual relationships. Such relationships dominate all of life. Their exception is the rare event. Together, in their multiplicity, these constitute living communities, living in the very specific ‘biomes’, found on larger, seemingly independent organisms. Numbering in the thousands, millions, billions, even trillions, these tiny residents live in dynamic symbiotic, mutualistic, parasitic and antagonistic relationships with their hosts, often filling more than one role, depending on the host, the conditions and constitution of the biotic community. Whew! Yong’s book introduction, of the reader to this world, should lay to rest the idea that ‘we’ are truly ‘individuals’. The countless microbes that occupy and ‘invade’ us, have previously been considered unnecessary or consistently compromise our health, sources of disease.…The idea that we can ‘sterilize’ our way to better health denies the necessity of these organisms, or at least most of them, in the health of individuals.

No, he presents a variety of cases which illustrate the absolute dependence of an individual on these microbes, bacteria that breakdown our otherwise indigestible foods into forms that we can then absorb and utilize. Others that may live on our skin, defending us from attack, by providing a defense against other microbes that could otherwise infect us. Their are microbes that infect other microbes (see Martinez Arias’ book, “The Good Virus”), tiny ‘organisms’ that infect that disease’s vector, killing it before we become infected or blocking the disease causing microbe from infecting the vector, keeping it free from the organism which can cause disease in us.

The Good Virus, A Review and Thoughts About the Necessity of an Informed Public

Leave a reply

Every book tells a story, even the driest academic tome…or rather, utilizes the form of a story. Humans communicate through story. It’s how we give some communicable ‘form’ to our thoughts which we can share. Without it everything is disconnected reportage of facts, personal impressions, emotions. Raw data. Zeros and ones. incomprehensible. To communicate through story requires that we share enough elements of the story, its language, form and ideas, with our ‘listener’, that they can understand what we are saying/writing. If it is too alien, communication does not happen. The listener/reader, hears the words, but the meaning eludes them. Meaning and experience are not shared. Without these, connection, communication, fails. The more esoteric the topic, the more important it is that both ‘parties’ share a common language, that  each is ‘educated’ to some degree, about the world the other is attempting to communicate. As science and technology become ever more specialized and schools and social institutions become more isolated from their larger communities, communication fails more often than not. Especially when the ‘other’ is viewed in a negative light, as untrustworthy. Communication then requires a leap of faith, because as our understanding of the world becomes deeper and more complex, we cannot all become expert in all things. There is just too much to learn. This is when effort, trust and faith, become essential. We must share a commonality, a trust in the other. As shared knowledge, and ‘ways of knowing’ decline, assumptions then dominate. Intentions then become suspect and the very possibility of community and communication evaporate. What we ‘see’, is what ‘we’ see, not what someone else does. Whether or not that is shared is the crux of the communication problem.  Continue reading →

On the Danger of Being ‘Normal’ and Exclusive: The ‘Queer’, Diversity and its Essential Nature

Leave a reply
  • I’m a thematic reader, certain topics appeal to me. My tendency is to dive in when they fit into the puzzle that intrigues me, particularly the big one about life; what it means to be alive; what organisms share in terms of their biological function as well as what connects us…all of us, as a species and more broadly across species; the ecology of life, how we fit together, necessarily; how this life would not exist  were we truly individuals, separate, isolated, independent organisms and how we delude ourselves when we insist otherwise. One book often leads me to the next. Sometimes several. So I read about quantum physics and how as we integrate that into biology, it transforms that science, adds an element of ‘magic’ to it. Neurobiology. Ecology. Evolution, The embryogenesis of that single egg cell to the the dividing undifferentiated blastula, to a mature organism with its multiplicity of differentiated cells, unique tissues and specialized organs. Metabolism. Gender and sexuality. Perception and consciousness, its complexity and variety. Relationship, function, communication, internal ‘signaling’ and ‘switching’.  How concepts of sentience and beauty, language and art, the soul, all spring from the complex act of living…. Integral to it. How species and individuals all play roles, simultaneously in every level of ‘community’ in which they belong/participate, indispensable and replaceable, all related parts of an ongoing, evolving, process; one that we are so embedded in that we cannot possibly discern the value of anyone ‘member’s’ contribution, each an element in the larger dance, a ‘process’ which itself, is the point. As Shakespeare once wrote in his play, “As You Like It”:

All the world’s a stage,
And all the men and women merely players;
They have their exits and their entrances,
And one man in his time plays many parts….

We do not and cannot know the ending. There is none, or rather each ending marks a beginning, any guess that we might offer of an ultimate purpose, of a goal, remains unknowable, beyond the continuing unfolding of life…endless change.. Progress? It’s difficult to say as the earth system collapses and ‘reboots’ over time. The expression of the whole is observable only in moments, in its parts.

The aphorism, ‘it takes a village to raise a child’, begins to get at what it means to be alive, that we all depend on each other, connected, related through the dynamic processes of being, of the flow of energy and its ‘in-forming’, its translation into matter and form. We are each a unique expression of this process. If we are ever to fulfill our potential, if we will ever be able to discern what that might be, we must recognize these connections. Our individuality is a selfish story we tell ourselves, one that fires our ambition to differentiate ourselves, to put ourselves ‘above’ others, to claim exceptionalism, and in so doing, lose the larger game playing out before us. As ‘individuals’ we are incomplete, hobbled in our larger social and ecological roles, we devalue ourselves when we fail,  and in so doing see ourselves as separate, individuals rather than the ‘collectives’ that we are. We may act individually, actions which are informed by both our past and the actions of all around us, but are in fact linked directly by lines of dependency, recognized or not. We are forever a part of something much larger than ourselves. We are bounded composites, never truly independent, as both individuals and a species, communities integrated into these unique wholes, even our consciousness is a product of this collective relationship. ‘Shaped’ by and shaping the conditions in which we live. The synapses in our brains both fluid and solid, responding to the world around us and with in, with our use and disuse. Connected in countless unseen ways, essential and impactful never the less.

The Lost Trees of Willow Avenue, a Review

Leave a reply

Global climate change, in our current political climate, has been relegated to a secondary status. There is so much ‘shit’ hitting the fan right now that it gets largely lost in mainstream media coverage. The science that supports it, continues, although at a slower rate. Our transition from fossil fuels to renewable energy has slowed along with the republican denials, their actions to ‘deBidenize’ America, cutting funds appropriated through the Inflation Reduction Act, ‘seed’ monies to fund needed infrastructure investment, along with their cuts to the funding of research into the supporting science and technologies. The topic has been rendered into one of ‘belief’ as if its consequences will have no real world effects, a simple argument of the uninformed, like ‘Ford beats Chevy’, pointless and personal. Author Mike Tidwell, an obvious long time ‘believer’ and lobbyist, has worked over the last 30 years to move the political dial toward climate action, amongst his neighbors, his home state of Maryland and Congress. Here, in his recent book, “The Lost Trees of Willow Avenue”, he tells his and his neighbor’s story, in his DC area neighborhood, of the real world impacts they’ve observed and are attempting to combat. Amongst his neighbors are  Congressman Jamie Raskin, his friend, Ning, a college prof who has been working tirelessly on getting a novel carbon sequestration program up and running, a local state legislator who has been working to get massive scale wind generators built off shore and others working in smaller ways, dealing with the fall out of a climate already changing around them which, among other things, is causing crazy weather perturbations, changes in rainfall and temperature swings that are leading to things like a large increase in Lyme disease, because the milder winters are killing fewer of the disease carrying ticks, while also leading to the massive die off of mature trees across their neighborhood.

The Cut Leaf Thelypody in Dry Canyon

Leave a reply

[Plants of the Dry Canyon Natural Area – This will be the start of a new series focused on the plants of Redmond’s Dry Canyon. I’m creating them to be posted for ‘local’ consumption on the Friends of North Dry Canyon Natural Area. It’s a City Park including about 166 acres at the north end of Dry Canyon Park which the City has identified as a Natural Preserve. The group works as an advocate with the City, on public education and helping with on the ground work projects. I’ll identify each such post here.]

As you walk the trails below the canyon rims you will be seeing these growing scattered and in bunches. This is the Cut Leaf Thelypody, Thelypodium lacinatum. These are common where ever there’s a bit of soil between the rocks on the slopes below the rims growing amongst the tumble of massive basalt. I’ve seen these elsewhere growing in other eastside Oregon canyons with similar conditions.
These are members of the Mustard family, prolific seed producers and quite competitive. Another plant that, at least so far, doesn’t venture out into the canyon’s bottomland.
Elegant when it first starts flowering, like so many native annuals and perennials, these start declining while they proceed through their flowering season detracting from their appearance. What do I mean…each spent flower, begins to form its narrow, linear, Mustard seed capsule, quickly maturing its tiny seed and then drying, twisting and browning, while the inflorescence continues to bloom out towards its terminal end. A little messy, yes, but characteristic of these plants. We humans are relatively intolerant of such decline in our garden plants and so generally refuse them admission. Under the local wild conditions, as dry as they are, species tend to either be early flowering, when soil moisture is still most available or those like this that begin to decline before the show is over. Summer drought is a ‘cruel’ taskmaster. There are exceptions to this rule but….

The Serviceberry: Abundance and Reciprocity in the Natural World, A Review

Leave a reply

Robin Wall Kimmerer is a botanist, ecologist, a teacher and a member of the Potawatomi people of the Great Lakes region, from whom she learned her people’s particular world view, one once common amongst many indigenous peoples and in stark contrast to that of our present day dominant culture, which has lead us to powerfully shape our our world today. Her three popular books, “Gathering Moss”, “Braiding Sweetgrass” and her latest, “The Serviceberry”, present to the reader a glimpse into the natural world as seen from this ‘alternative’ world view. All three are enlightening reads and not overly technical. They are ‘invitations’ to see the world from a different perspective. The latest is the smallest, a book barely over 100 pages, with large type and in a small page format…a quick read, unless you pause to give what she presents some additional thought. The best, and the one I read first, is “Braiding Sweetgrass”.  Continue reading →

On Ornamental Trees and the Remaking/Unmaking of Place: Revising the City of Redmond’s Tree List, part 2

How Much to Water?

Recommending trees from climates with significantly wetter growing seasons needs to stop if we are to continue growing our population. Landscapes as designed, and managed, are the single largest user of residential water. Recommending trees which ignore this problem is irresponsible. Lower water use residential landscapes are possible. Local codes and recommendations must, however, reflect this priority.

Additionally, how much to water is a bit of a mystery to all of us and especially so to non-gardeners. How much? How often? Our watering practices should be determined by the local precipitation and the tree’s needs. What is commonly done, however, is that we water for our lawns and that largely determines what our trees receive, unless we have separate drip systems. A tree’s root system doesn’t stay neatly between the lines. They quickly extend out well beyond the span of the tree’s leafy canopy. In many cases even 2-3 times as far, taking up water and nutrients. A roots of a tree, planted in a small bed, adjacent to an irrigated lawn area, will move out into the lawn. A tree isolated in a xeric bed with only a few drip emitters, will quickly demand more than such a meager system affords it and such a tree, if it requires summer moisture, will struggle while competing with its nearby  ground level growing neighbors. Again ‘neighbors’ should share compatible requirements so all can thrive on the same ‘diet’ and moisture regime. Continue reading →
