Toward the Formation of The Central Oregon Tree Explorers

Leave a reply

Paleontoiogists say that we first evolved as a species on the African savanna, that mixed landscape of grassland and scattered trees. Some argue that we were first a tree associated species. Be that as it may, most people have an affinity for trees today. We have our favorites. We plant them for food, as a source of material to meet various needs, for shade, for that inexplicable feeling we have when amongst them, in support of the life that came before, those dynamic communities, their complexity and the vitality, that define these places we now occupy, for their beauty. In Central Oregon with our arid to semi-arid climates, those with annual precipitation as high as 15”-20”, xeric referring to our dry summer growing season, our native trees serve as an indicator of the possible. Our local landscapes have curvilinear boundaries, that delineate areas with like moisture regimes. These go a long way in determining the native landscape (But not all of the way!).
14” of precipitation locally is roughly the bottom limit for Ponderosa Pine. You can see this as you observe grouping and the massing of tree species, forming a line from south of Bend, west and north to Sisters, then along Green Ridge and north to the Columbia. There is an in-between landscape, an ecotone, where the Ponderosa intermingle with the Western Juniper, which dominate easterly, until the average drops below what even that reduced amount can support. The ecotone roughly bisects Bend. Continue reading →

On the Creation of an Urban Tree Canopy Management Plan for Redmond, Oregon

2 Replies

Trees can be a defining element of a community as a ‘success’ story, a failure or somewhere in-between. A community’s trees are of it, not some separate amenity provided by the City. Ideally, just as the canopy is part of a community, its care should be a part of the shared responsibility of the community, with the City providing the services the community cannot, in addition to their role of coordinating the care so that the tree canopy can provide the highest level of service while meeting aesthetic needs. The City is ideally situated to perform this role. Neither ‘group’, the community or the City can do this on their own. Training, education, outreach, project implementation (planting, tree care) are a joint responsibility. Leaving this as a City responsibility alone cannot result in the best product. Communication and partnerships should define the relationship and effort.

Picking numerical targets for increasing overall tree canopy misses the mark. We don’t just need numbers, we need site and species appropriate trees in order to grow out a healthy urban canopy that is neither water intensive, given our climate and declining aquifer, nor one that increases overall wildfire risk; one that helps us, a portion of the more powerful human residents, bridge the gap between the contrived landscape in which we spend most of our lives, and the wild, evolving landscape outside our communities, that operates in ways that balance all the competing and supportive needs, of all of the species that comprise it. Our ‘developed’ communities, heavily prioritize a narrow fraction of the lives within them.

Tree selections should be supportive of local wildlife and pollinators in addition to providing the environmental services associated with urban tree canopies…not just those of the decision makers within the human community. Planting the wrong trees to get initial numbers up, as some kind of marker of success, will be relatively short lived at best. Trees are a long term, living and growing investment, that shape the future. However we slice it, they will demand water in larger amounts as they grow over time. So our choices should be thoughtful and considered. At issue is whether the normal growing conditions can adequately support the growth of chosen trees. We know that almost any other tree, beyond our Western Juniper, will require supplemental water. How much though we need to weigh. When tree and climate are a mismatch the result is evidenced locally by the increasing numbers of shade trees around town where owners have turned off the water leading to stressed and dying trees. Success is absolutely dependent upon well chosen trees, their ongoing care and the participation of an informed public.

Political Chaos, Wildfire and Drought: We have a choice, but not a lot of time

Leave a reply

I don’t usually repost what I’ve put on my FB page, but the world just keeps getting crazier politically, so much so that our new reality is being lost in the chaos. Now is not the time to give up. As bleak as things may seem to be becoming…it will be far worse if we don’t do what we can to implement a course correction.

If you want to keep your head in the sand, if you believe in the stagnant and bleak Trumpian promises of a return to a ‘golden’ past, if you truly believe that the MAGA movement contains all of the answers we require…don’t read any further. It will only upset you.

Picture from a Spokane, WA area newspaper of one devastated residential neighborhood.

As I write this the world is literally burning. Round it up and there are 2 million acres in Oregon alone either already burned or in the process of doing so this summer, with several months still to go in our ‘fire season’. There are multiple fires each over 100,000 acres. In Washington state Spokane continues to burn. In Bordeaux region of France hundreds of thousands of residents were evacuated while others were because of a fire threatening Madrid, Spain. Most of Europe is undergoing it’s fourth major heat wave with thousands having died as a result. As the drought in the American West and western Europe deepens the flow of rivers and the level of reservoirs across the Western US drop to or near record lows, all while demand for water keeps increasing. There is so much excessive heat and fire around the globe right now that it would overwhelm the news cycle to report it…so we only hear about those most local. Some are publicly claiming it to be a result of a singular ‘super-El Nino’, while most climatologists see this as the new normal, with much worse extremes to come, on an over heated planet.

The Nutrient Cycling Role of Fire in Central Oregon’s Arid Landscapes

Leave a reply

A Juniper like this one, growing out on BLM land around Cline Buttes, attains this squat and sturdy stature only after hundreds of years. Growing as they do on shallow, raised rocky areas, not only do they grow slowly, but there tendency is to caliper up. In irrigated pastures, these grow overly fast, spindly and upright. Look at that taper!

Ecologists will regularly claim that fire plays an essential role in the life and dynamics of the Juniper woodland, our sagebrush steppe and the grasslands of our arid and semi-arid plant communities, that without it, the landscape will deteriorate. Okay, but what does that mean? How can fire actually lead to a landscape’s improved vitality and diversity? What does fire actually do and what happens when it is eliminated? The short answer is that fire, in burning the collected fuels on the ground, breaks them down and returns them in nutrient form to the soil and the cycle of life. It provides the space necessary for a healthy and diverse landscape. To get there requires more thinking.

First some essential definitions and clarifications are needed: what are these ‘types’ of landscapes that together can be found in the arid reaches of Central Oregon; all landscapes are dynamic, evolving, changing over time according to the forces in effect on them, they are not static or fixed; what is meant by arid and semi-arid; fire, what is it, what is actually occurring when something ‘burns’; what is going on at a molecular level when an arid landscape burns; if this is so necessary, what fulfills this role in wetter landscapes; what’s the relationship between fire, rot and digestion; how, and does it, serve the nutrient availability and the necessities of organic growth. In understanding these basic parts we can better understand the self-renewing CYCLE of life as an ongoing process and how disruptions to it negatively influence its capacity to continue.

Crossings: How Road Ecology is Shaping the Future of Our Planet, My Thoughts on Goldfarb’s Book

Leave a reply

Had I not read Ben Goldfarb’s 2018 book, “Eager”, I probably wouldn’t have picked this one up. Why would I want to read an entire book on ‘roadkill’? But I trusted him. And so I read it. 

I found his writing here crisp and engaging, like his other work, but I was still hesitant and did my reading in fits and starts. I’ve read several books lately about impending environmental crises and I didn’t really have the energy to do another, but I did finish it and found it a worthwhile and satisfying experience. Amongst these earlier books was Slaght’s, “Tiger’s Between Empires” which returned repeatedly to the problem of how devastating even the relatively little travelled roads of Russia’s remote Primorye Province are for its endangered population of Amur Tigers. In the world of ecology, roads routinely bring death to the wildlife they literally impact, as well as because of the discontinuities they create in the landscape, physical and chemical changes they visit upon the animal’s environment and the surrounding biotic communities. This is about the wholesale implementation of a technology ‘alien’ to the animal world, that purports to meet the ‘needs’ of humans while making little allowance for the uncounted species that reside alongside them.

Nature’s Ghosts, Sophie Yeo’s Look into Ecology, the Loss of Species and Habitat, in a World that is more than mud, leaves and atoms.

Leave a reply

 

An ecological study tends to start with a particular species, a place or biotic community and then goes on to define it in terms of its relationships with its various members and the place itself, with its physical conditions. Sophie Yeo, the author of, “Nature’s Ghosts: the world we lost and how to bring it back”, does that, but where most of the books I’ve read take a narrower view and focus on a particular species or place, Yeo takes a both ‘local’ and a more global view as well as one that goes back deeply in time. Hers is not a book limited strictly to ecology as we generally understand it, because she is interested in it as a tool, a tool for reclaiming what has been lost, the ‘Ghosts’ of her title.

As a horticulturist, who took care of landscapes, this book has strong appeal, because not only does it look at life and all of its integral relationships, she includes us, the humans, who so often set ourselves separate in the rarified and an exceptional world of our own making. This is also a critique of this decision in which she writes to show us where and how we belong in this world, how we once were very much a part, how we behaved as a ‘keystone’ species, actors in a landscape, shapers, ‘creators’, and how now, as consumers/destroyers, because of our self ascribed position as superior beings, we became removed and exceptional, a threat to the our other community members, as we changed the world into one that allowed them less and less space. It’s a tall order, what she sets out to do here, but I think she largely succeeds and she does so in a way, with language that is almost lyrical, beautiful at times, and like a ‘bad’ scientist, introduces herself into her story, along with the emotion and clarity that being a new mother can give one’s self.  Continue reading →

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 →

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 Seat of Awareness: On Plants and What We can Learn from Them

Leave a reply

“From the viewpoint of the evolutionary biologist it is reasonable to assume that the sensitive, embodied actions of plants and bacteria are part of the same continuum of perception and action that culminates in our most revered mental attributes. “Mind” may be the result of interacting cells. Mind and body, perceiving and living, are equally self-referring, self-reflexive processes already present in the earliest bacteria.”
—Lynn Margulis and Dorian Sagan, “What is Life?”, 1995

From what do sentience, awareness, consciousness and intelligence come from? Are these capacities a product of an organism’s complexity? At what point does it first appear? is it a property inherent to even the simplest organic chemicals? of peptide chains and amino acids, of atoms themselves?What of the organizing principle that seems to guide embryogenesis, the growth and form of every living individual of every species? Is it in action in the most ‘simple’ interactions between organic chemicals and the energy flowing through them, that favors one form over another and animates those same forms once they meet some critical minimal level of complexity?  Is this evolution towards complexity and ‘awareness’ an inevitability? A product of its component parts and the energies within it? [This is an idea that is separate from the notion of an inevitable ‘progress’ of life, always moving ‘forward’. Progress is a human notion, an assessment and a valuation of the change around us, not a ‘goal’ of natural selection and the animating ‘flux’ of energies within the universe.] Rudimentary awareness must exists at some necessary and basic level in the simplest single celled organisms…even in plants.

I look to that which is shared between all organisms and question the idea of the animal brain, and its neural system, as the basis for these things and its purported absence in plants, fungi, bacteria, viruses and archaea, as lacking in them. The brain itself and associated nervous system is a unique and complex structure present only in ‘higher’ animals. This bias in favor of the brain and neural systems, especially that of the human brain, as the seat of awareness and consciousness, ignores the requirements of any organism. We are biased in our insistence that these capacities must be located in a singular physical organ and no other. A singular occurrence in the universe. A huge conceit on our part, that this capacity exists in us alone, in and organ and tissues we could could physically evaluate, one which we ‘carry’ internally within us as we move freely about. The body, any body, is a vessel which contains life and is shaped by it. Life is both of the body and transcendent, existing beyond it. Life exists within the continuously unfolding moment. Life is not a ‘thing’ so one can hardly expect awareness, consciousness and intelligence to fit neatly into a limited organ, however we define it. The roots of this reach back into the study of evolution, ecology, cell biology, neurobiology, the metabolism and thermodynamics of life and the expanding field of quantum biology.

This latest thought piece has been inspired by three recent books I’ve read, Ed Yong’s, “An Immense World”, Paco Calvo’s, “Planta Sapiens” and Zoe Schlanger’s, “The Light Eaters”. I am not a scientist. I’m a student driven to make sense of this world. The connections and conclusions I make here are mine, although they may be suggested by the writings of others.
