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

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.

On Wilding and the Return of Nature: Thoughts on an Idea

Talk of environmental crises is everywhere, climate change, mass species extinctions, losses of critical habitat, the privatization of once public resources and landscapes (and their subsequent ‘pillaging’ by corporate entities), critically dropping aquifers, what a chaotic climate may mean for world agriculture and our food supply, a world beset by an increasing rate of diseases and diminishing efficacy of the tools we have to combat and treat them….it is daunting and depressing. At the same time, generally barely mentioned in mainstream media, are notices of studies and ideas of what we can do to not just lessen these problems, quite a few of which are being implemented, but to repair the organic and global systems, whose faltering is leading to these increasing problems and potential catastrophes. To make head way on these is going to require a much more concerted effort by most of us. What, many are asking, can we do to usher in a return to a healthier, better functioning, world…before any looming system ‘course corrections’ do the ‘work’ themselves, eliminating the human problem, that ’we’ have collectively become. 

Isabella Tree’s, “Wilding: the Return of Nature to a British Farm”, which prompted this post, supports an approach in which mankind takes on a more responsive and respectful, while simultaneously, a less active role, in the management of the landscape. A ‘less active role’ because what she’s describing requires that we step back, relinquish some control, and allow the powers of nature to heal itself, stepping in where, when and how we must when those ‘forces’, diminished to the point where they are ineffectual, need the support…but no more. She calls for us to trust that our own evolved status is a product of the natural world, a potent nature with the inherent capacities and tendencies, to create, balance and heal, in like proportion to what it ‘takes’ and consumes; that we reclaim our ‘membership’, our historical relationship with this place and all of the life with which we share it. We are active agents of change and must, to the same extent, do the necessary work to heal those wounds, we’ve inflicted upon it through our economic demands and  industrial power. Her story here is one of a shared fate and a faith in life, which is illustrated time and again as she and her husband, Charlie Burrell, work to understand the land and life they are beginning to re-envision, more as curious students than confident ‘experts’. The process quickly becomes one of open discovery as they attempt to understand the health of the place they previously managed as a farm, with the economic expectations of a modern world that has itself become disengaged from life, seeing it narrowly in economic terms that had long ago been separated from ecological reality, limits. and the richness of a place.

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

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.

 

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

Redmond’s Dry Canyon Firewise Management Plan, a Critique and Call to Action

Those who follow such things know that I’ve been involved in the preservation and enhancement of Redmond’s Dry Canyon, joining with others to form the Friends of North Dry Canyon Natural Area as an advocacy group, working to educate the public about its qualities and fragility, while also providing ‘boots on the ground’ with clean up projects and the control of threatening Invasive plants. Most recently we’ve been supporting other groups and participating with a guided naturalist walk, a bat walk and a recent Botany and Birds, walk with the High Desert Chapter of the Oregon Native Plant Society and Queer as Flock, a bird watcher’s group. We’ve been advocating for better signage, a trails management plan and for increased efforts to control the illegal use of electric and gas powered motorcycles in the Canyon. Additionally we have be doing the Juniper survey work for the City, to help create a plant data base linked with the City’s GIS program to aid them/us in the development of an effective management plan for Dry Canyon. We’ve only been recently notified, along with the rest of the public, that the City has a new Dry Canyon Firewise Management Plan (a PDF is linked below), which we were assured included participation by foresters, local natural resource and conservation groups…yet, somehow, they’ve produced a one dimensional plan with the singular priority of eliminating the chances of a catastrophic fire, while ignoring virtually all other priorities!!!!

The Eager Beaver: Sociology, Ecology and the Role of Relationship in Life and Community

Ben Goldfarb’s, “Eager: The Surprising, Secret Life of Beavers and Why they Matter”, is an excellent model for other authors who write on ecology for the interested lay public. It is also an excellent entry for the novice into the world and thinking of ecology. As in any other ecological examination of a species, Goldfarb tells us about the roles and relationships the beaver has in their particular landscapes, how they fit in. In doing this he tells its history, that is, its historical role in the lives of us humans, and we in its, alongside those it shares intimately with the other species of its biotic community. It is a book very much about this important animal’s relationships, and, by extension those of our own and every other species on the planet. The beaver’s, or as the author also refers to them, the Castorid story, (the latinized name of our North American species is Castor canadensis, its old world counterpart, the other species, Castor fiber) is closely linked to our own. We, as the ‘dominant’ player in our landscape, have overlooked the beaver’s pivotal role in the world of water including the rivers, streams, ditches, ponds and seeps that ‘water’ the desert. Beavers were essential in the historical landscape and now, in their absence, our landscapes are often very much diminished. Wildlife, and even farmers and ranchers, who have often vilified them, are slowly beginning to understand the benefits their presence can provide, benefits that far out weigh any negative impacts they bring with them. People are, however, stubborn with long and selective memories. It is not easy for anyone to let their misconceptions go and accept what you have always rejected as patently false. Continue reading

On Our Western Juniper Survey in Redmond’s Dry Canyon

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

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.

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

Mowing Firebreaks Across the Dry Canyon Bottom, Good Idea or No?

Mowing weakens the native plant community and aids the growth of weeds.

Mown adjacent to unmown. Aggressive spreaders will fill in more quickly and because of the weeds already in place, they will sieze a larger proportion of the mown area as they grow and spread.

While recently walking home through the Canyon, last month in December, I noted 8 new  strips, presumably ‘fire breaks’, mown across relatively flat and uniform sections of bottomland, each maybe 50’+ wide, spanning the bottom between the paved eastern path and the the main dirt western bike path. While I understand the thinking here, removing ground level fuels, this is a single purpose treatment that works counter to the Park’s purpose as a natural area preserve. Mowing down the Rabbitbrush, a ruderal, transition species of the Sagebrush Steppe plant community, delays the development of a healthy native plant community and encourages an increased array and density of weeds and invasives. Mowing this way provides open space for weed species already in Dry Canyon, as well as those not yet here, giving them larger ‘launch points’ from which they can spread into the rest of the Canyon. Mowing weakens natives, which are naturally slower to rebound from the damage than the aggressive weed species. Continue reading
