Weeds, Weeding and the Health of Our Public and Private Landscapes: an example from the ‘hood

Every gardener is a weeder. Gardens are created landscapes, often expressions of the individual gardener or, lacking of intent and design sense, those of a chosen designer. We live in our landscapes as active, responsible, creators, participants and stewards. Gardeners are trying to create a particular look or to grow particular plants native to their area, or with ornamental value or food plants to feed themselves and their families. Some of us are simply pursuing what we understand to be a healthy relationship with one’s place, to undo the damage and allow a new healthy and vital landscape to grow. These are landscapes of our choice. Our intention and control results in various volunteers and weeds finding their own place and so follows the need for weeding. 

We watch carefully, monitor the impacts of our work, attempt to understand what result is moving us closer to our goal and which might be indicators of further loss. Landscapes and gardens are incredibly complex systems and anyone who claims to have all of the answers is fooling himself and you. Our landscapes are broken, by us and our predecessors. The Pandora’s Box of weeds and disruption was burst open long ago. The only way ahead is to find a new path.  Weeds are here filling the niches we have collectively made and maintain for them. The more one is surrounded by aggressive, well adapted weeds, the more time we must spend controlling them. While this can be significant, gardeners mostly take the work in stride, a necessity to reach our goal, a goal which may be the simple act itself, of working in concert with our place…open to its teachings. Gardening, is a way of life, a smaller scale version of farming and the management of large ‘natural areas’ with their attendant commitment, rhythms and demands. Continue reading

The Flushing/Testing of Redmond’s New Municpal Well Into Dry Canyon’s Natural Preserve

This shows the effected portion of Dry Canyon Park from Antler, at the bottom, where the new municipal well is located, north to the Maple St. Bridge. The Fir connector trail shows up faintly cutting diagonally across the canyon from Fir Ave, 3 blocks north of John Tuck School. West Canyon Rim Park is labelled on the the left. The trail/dam cuts up, northeasterly from it, gray as it is asphalted, faintly in the pic. The water travelled 200 yds north of it, a bit short of halfway up to the Maple Bridge.

I’ve adopted Redmond’s Dry Canyon Park as a project, so I’ve gotten kind of possessive about things that threaten and effect it…but it is a City Park and cities often have competing demands and priorities. In this case the City is under considerable pressure to keep growing. People and businesses are still arriving here at a high rate and this puts demands on its public infrastructure, in this case its water supply. A city of its size also finds itself in need of more Park lands as people’s private space shrinks, population density increases and we all turn to the same limited landscapes for recreation. Compound this with the demand of wildlife and plants for relatively undisturbed landscapes on which they can simply live. Well, this is a case where two of these priorities have come into conflict, and as usual, the utilitarian demands have won out over those for the living natural world (There is no division of the City or local advocacy group, at this point, speaking up for the natural landscape and the life it supports). The utilitarian ‘needs’ of the community are simply a higher priority than those of the natural world. The State is responsible for our water resource and has control over adding new wells and how that is to be done. It is in at least part a health and safety issue. In this role they require that municipalities flush the wells and conduct a flow test to determine rate, drawdown and recovery. This was to be done by running it at full volume 24 hours a day for four days. At 3,500 gals./min. That’s 5 million gals per day. 20 million gals total. That water must go somewhere. It would have overwhelmed our wastewater treatment plant which is running at close to capacity already so it couldn’t be wasted down a manhole…so, it had to be wasted into the landscape of the Canyon itself.

The City contested this amount. This is almost double the amount used by by all residents on a typical winter day of 2.7 million gallons (In summer, due to landscape irrigation the daily amount jumps to 15.8 million gals.). This was all to be ‘wasted’ across the canyon floor. The City had concerns with damage to area infrastructure and paved paths. This requirement was cut in half and eventually to a single 12 hour period as the flooding/washing problem played out. The amount flushed was 2.5 million gals.

The filling ‘reservoir’ abutting the north path.

I was unaware of the details of this as I walked the stretch of path this afternoon  going north along the west side dirt path, from the trail connector between the main paved trail, extending from the Fir Ave. stairs. I was surprised at all of the surface erosion on and around the dirt path. In some places a foot or more of path had been scoured away, flushed out into the surrounding landscape, its Bitterbrush, Rabbitbrush and other low plants. This erosion continued north following the contours and the trail.

The northern extreme of the test run, where the flow slowed and settled all of the light organic debris.

As the flow spreads and slows larger denser material settles out. Here sediment was deposited in the trail itself and on the ground where the water fanned out.

The flooding had continued a couple hundred yards to where the flow stopped depositing a layer of organic debris the water had carried along.

(I learned on the 17th that this was the result of a test to see what kind of damage might occur and to gauge how the water would spread across the site. This is why the crew was there on the 17th. The test was an attempt to determine the flow pattern so that they could minimize damage.) Continue reading

Dry Canyon Proposal: the need for change in maintenance, use and planning

[The following is a piece I wrote and sent to our local Parks staff, its advisory citizens committee, mayor and city manager…I got little back in response. I’ve developed a relationship with one of the city arborists and the park’s planner as well as have met several active neighbors interested in protecting Dry Canyon’s natural areas, several of whom have natural resources backgrounds with agencies. The City has no natural resource or botanical staff. There is no formalized friends group, nor is their an outreach and public education program that addresses these problems and the role of residents in their solution. Signage is minimal and inadequate. Their horticultural expertise would also seem quite limited. This is understandable as the City’s population has grown very rapidly in recent years. The need for such programs and an increase in expertise on staff will only increase as Redmond’s population continues to grow.]

 

Redmond’s Dry Canyon looking south from the west rim on the Maple Street Bridge. The area in the immediate foreground burned this last summer.

A typical view at the base of a section of relatively unbroken rim on the east side.

The canyon floor is variable, but as this pic shows, a solid layer of hardened lava underlies what soil is here, either blown in or washed in, a limiting factor of what can grow here. Rabbitbrush is a common and ubiquitous native pioneer.

Match of the canyon floor is recovering from pasture use. These areas have relatively deep soils and are still transitioning with many weedy mustards, annual grasses like Cheat and planted grasses like Crested Wheat and Annual Barley. Native Bluebunch Wheat is scattered as are other natives. Gray Rabbitbrush, a native seral species has moved into much of it, but the weeds are dominant. Sagebrush and Bitterbrush are more at the edges and lower rim areas.

This section of bottomland, former pasture, probably burned not that long ago, has quite a colony of Rabbitbrush coming along, all it would appear of even age, suggesting a fire. Rabbitbrush are early colonizers and ‘prepare’ the way for natives to follow. This is just north of the Maple Bridge.

This area, maybe 5 acres, burned in July. It will be interesting to see what comes back and what the City may plant??? Fire kills Sagebrush and Juniper, while it seems to favor Cheatgrass. So far, April ’24, nothing has been replanted. The window for seeding is closed. Rabbitbrush can survive a burn. This site is unfenced, with very fragile soils and we’ve already observed new bike trails in it.

My wife and I are both recent returnees to Central Oregon having both grown up here. We are also frequent walkers in Dry Canyon, a place I spent many hours in playing and exploring as a kid in the 60’s. Redmond has changed a lot over the intervening years…change that continues apace as it grows. I’m not going to whine about the ‘good old days’ and things lost. Much of the change I welcome or at least accept (We did move back!), but population growth, in addition to bringing along economic vitality and stability, new and enriching opportunities and a more diverse community, increases the ‘pressures’ on the naturally limited assets that largely define the place and attract residents. I’m speaking here of the natural landscape, its features and the opportunities which it affords us for recreation and quiet enjoyment. Realtors were once fond of saying that no one is making new land, as a prompt for buying…it is a fixed and limited quantity. This limitation has profound implications for a growing population. We have far more people today ‘enjoying’ a limited, and increasingly over utilized landscape. Continue reading

Determined: A Science of Life Without Free Will, a Review and Look Into its Consistency With the Sciences

Long ago I took a couple philosophy classes at U of O; one on existentialism, in which we read several novels and discussed their themes; and another, an upper division, class on ethics, because I was curious…I dropped the ethics class after sitting around the table in seminar discussing particular authors’ thoughts, like Kierkegaard and Butler. Majors seemed to take pleasure in making fun of what I got from them in discussions. Hated this. I still have trouble reading philosophy. It seemed like a game to them in which they argued a position to show off their cleverness, their superiority, the ideas themselves of relatively little importance…while hiding their biases. It must have been so self-assuring for them to ‘know’ these author’s precise thoughts and bash those who don’t get it…or saw something different (like the newbie, me). To quote someone isn’t to understand, it is only miming, presumably in hope of getting a reward. I read for understanding. It’s not a competition. So, this book, “Determined: A Science of Life Without Free Will”, taking a science approach to evaluate a philosophical concept, was difficult to begin. The author, neuro-biologist Robert Sapolsky, argues that those philosophers and theologians who claim that people have free will to do whatever they desire or set their minds to, are wrong. This appealed to me immediately. Continue reading

Knapweeds in Redmond’s Dry Canyon and the Pursuit of a Healthy Landscape

Redmond’s Dry Canyon looking south from the west rim on the Maple Street Bridge. The area in the immediate foreground burned this last summer.

If you garden, or maintain a landscape, you come to understand that not all weeds are the same. Each will have its own ‘strengths’, or perhaps you might call it ‘virulence’. Any particular weed, just like any other plant, will respond ‘positively’ to supportive growing conditions, conditions which often closely align with those which exist in its place of origin. Plant explorers and nursery growers are always looking for ‘new’ plants for landscape use. in a way, they have to walk a fine line. They must find plants, that with reasonable effort on the part of the gardener, can thrive across a range of conditions, unless they are looking for specialty plants, for narrow, niche, markets. The introduction of new plants must be somewhat measured, our enthusiasm tempered, because plants which are too adaptable, too vigorous, may possess the ability to escape our cultured gardens and find a place in the surrounding, uncultivated, landscape.

For Central Oregon, when we look beyond our regional natives, we must keep this in mind. Exotics from similar growing and climatic regions around the world offer both promise and threat. We want our plants to be successful, but not too. Sometimes through the process of trade, the movement of livestock and agricultural products, particularly aggressive species hitch a ride. A few weed seeds can be easy to miss. If they are aggressive enough and go unnoticed, a distinct possibility, it is likely that they wont be detected until a sizable local population asserts itself…and if no one is watching, that can be a fateful error. One group of plants, with many wonderful possibilities, also include species which can be exceedingly problematic here in Central Oregon, these are from regions sometimes referred to as Steppe.

On Weeds, Disruption and the Breaking of Native Plant Communities: Toward a More Informed Working Definition of Weeds

The bottom land in Redmond’s Dry Canyon was used for decades as low quality pasture, the native community pretty much obliterated. Those areas with surface rock are more likely to retain more of the original plant community, although Cheatgrass has invaded much of those areas as well. The is looking southerly over one of the larger ‘pasture’ areas near the disc golf course. There is very little Cheatgrass through this section south of West Rim Park. It includes a few native seral species which typically occupy disturbed sites as a site transitions, including Gray Rabbitbrush you see here. Found in this area too is Secale cereale, Annual Rye, a non-native, which appears to have been planted along more formal paths to limit Cheatgrass spread(?).  Junipers are moving in. Sagebrush hasn’t yet.

It is commonly said that a weed is a plant out of place…and of course ‘we’ are the one’s who decide this. Some will try to argue that there are no weeds, that all plants belong and if we only left weeds alone landscapes would reach a balance on their own. If one’s time frame is long enough this may be the case, though this will take considerably longer than one of our lifetimes, and then there is our inability to actually leave landscapes on their own, or to at least consciously moderate our disturbance of them. Weeds are plants. They are not a separate classification of plants. They are plants removed from their places of origin and released into another where they have competitive advantages. Most people still simply tend to refer to plants they don’t like or want as weeds. These positions are at odds with one another. This leads to confusion and a lack of clarity, undermining any urgency to take action.

Weeds have become ‘personal’, their status a matter of ‘opinion’….A weed is a weed only if “I” agree that it is, or perhaps some ‘expert’, such as when agricultural scientist identify them as an economic threat to farms and label them as ‘noxious’. Without agreement and urgency there is a tendency to do nothing about them. Plants in general are attributed little intrinsic value. For many people they are just there. Native plants we vaguely understand as belonging to a place, but most people would be hard pressed to identify and name many at all. Quite different species are often lumped together, their relationships unnoticed. Natives are reduced to being ‘background’, their status reduced to decoration, attractive or not, a ‘space’ filler, perhaps a hinderance to what we would chose to do with a place. Continue reading

Spruce Park, Redmond’s Newest Park and Our Neighbor: a horticultural critique

Redmond’s Spruce Park looking NNE from the SW corner toward Gray Butte and Smith Rock in the background. The border beds which follow much of the loop path are ‘native’ plantings according to the conceptual plan. It is common to claim that most of the plants are natives in designed natural areas, but native is not synonymous with ‘natural’. Although natives are used here concessions have been made including such plants as Echinacea purpurea ‘Pow Wow Wildberry’ and Rudbeckia ‘Goldsturm’. In a strict sense Ponderosa Pine aren’t native to this immediate locale either, they require more precipitation than we normally get and the Autumn Blaze Maples are a hybrid of two northeastern North American species.

A landscape, in nature, is a whole, functioning system, capable of perpetuating itself, through out the seasons and years, relying entirely on its own conditions and the cycling of energy and resources occurring on and within it. This is also the definition of a modern sustainable landscape. Ideally they require no inputs or energies supplied from offsite aside from the sun, precipitation and the normal cycling onsite of nutrients and water. A human made, contrived landscape, as all of those built by us today are, may be ‘judged’ by how well they function on ‘their own’, by how well they fit this ideal. Labor and outside inputs necessary to maintain a landscape are then indicators of how out of balance, how far from ‘ideal’ nature and genuine sustainability, a landscape is. A contrived landscape, which ignores the relationships integral to a healthy landscape community ‘demands’ more and more maintenance and support. Given its design and use, a landscape which ignores its site and relationship requirements will deteriorate from the intended design, losing to death component plants while gaining, increasingly, more unwanted available weed species. Design, conditions and use are essential to determine, in this sense, what a ‘good’ landscape is. Continue reading

Why Bad Things Happen to Good Plants?: On Root Problems, Root Washing, Nursery Practices and Customers

“To be, or not to be? That is the question—Whether ’tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And, by opposing, end them?”  Hamlet.

Is the question we face as gardeners as simple as, To ‘root wash’ or not to ‘root wash’, before planting?  To some today it has become ‘heretical’ to suggest that it might not be just a necessary corrective, but an unmitigated good…and not doing so dooms a plant to failure.  The practice of ‘root washing’ in its present form, is relatively new to gardeners.  Horticulture, which is a system of techniques, traditions and science, that goes back to our own species’ first intentional involvement growing and selecting plants, has not always included it.  Practices develop over wide spans of time.  Many are retained, others pass away. Root washing has been around as a method to assess damage to root systems, to ease and make more efficient division, to study root growth or cleanse them of particular infestations.  ‘Bare-rooting’, during a plant’s winter dormancy in temperate regions, has historically been done in the field when harvesting or transplanting many deciduous trees and woody plants for shipping and ease of transport.  In some circles today root washing has become an almost literal flash point, pitting proponent against opponent, ‘science’ against ‘tradition’…yet another fracture line to divide society. The road of the absolutist, as with many other human practices, tends to create conflict as evidence of correctness is lobbed back and forth.  My own view is that, like so many other things today, the subject is somewhat ‘grayer’. Science can be on both ‘sides’, or neither, and reality is rarely so simplistic. Continue reading

Nature as a Model For Society and the Economy

For years now my real interest has been in plants and the life sciences.  This has lead me to better understand the physics and chemistry of life, of the organism, as I attempt to understand the truly awesome and fantastical phenomenon that is life itself.  I find it impossible to ignore the links between all of the sciences and it should not be too surprising that what one might learn in biology can have application for our own human species, including the social aspects of our lives, because whether we talk about art and beauty, economics or the institutions we share as humans, all are an outgrowth of our lives and the forces and cycles that govern us.  Primary among these is the phenomenon of relationship whether between the various ‘nested’ and interlinked cells in our own bodies or the countless organisms we share this world with, with which we in fact evolved, in both competitive and cooperative ways.  John Donne once pronounced in a poem that, ‘No man is an island’ and he meant that quite literally.  Our fate and health are all bound to one another whether we like it our not, in relationships which can be mutually beneficial, or, if we choose to ignore and deny them, in mutually destructive ways.  

Ecology is the study of a shared community of organisms, its description and how it all fits together, its relationships, ‘eco’ arising from the old greek word for household and logos, which speaks to order, purpose and form.  Economy, begins with that same concept of ‘household’ only its suffix comes from the greek word meaning management or distribution and refers to the function of the household, its processes and how it produces, distributes or apportions its resources and products…it refers to the actions whereby the ‘household’ lives, the actions, that characterize its many relationships.  In ancient Greece the economy revolved around the household.  In their world economic actions were not simply those by which a society achieves material ends, the Greeks also constrained it to those activities which resulted in ‘praiseworthy’ outcomes, those which provided a larger benefit to the household.  (Greek society, not perfect, was much like our own, placing women in a subservient role and was dependent upon slavery.  Like American democracy, it was exclusive, but capable of being expanded to include all peoples.) 

The two concepts remain closely linked though today our understanding of economy includes only those parts of the larger community’s operation, the money economy, that produces material benefit and wealth.  Any harm accrued or costs imposed on others is not directly relevant if such costs have been ‘outside’ of the transaction, beyond the responsibility of the buyer and seller’s deal.  Leaders have mutually decided to exclude all else.  We define our economy in a limited way that serves the production of wealth and its accumulation, making profit the purpose and most relevant factor in economic decision making, placing outside it that which we choose to, that which we under value and take for granted.  The two largest examples of this are our exclusion of domestic or women’s work, and the contribution of the environment.  To include them would radically change our economic calculations and the very concept of profit.

Profit is what remains after costs are considered.  To the degree that costs can be excluded then, profit is increased.  This ‘habit’ of exclusion extends throughout society and extends to whole sectors of the human population and beyond, distorting our decision making and the broader social and political structures that govern our lives….Our understanding of economics today exists outside of ethics.  Ethics and ethical behavior, if it is to factor into it, must be imposed.  That is the responsibility of a society through its political processes.  Such decisions lie within the realm of possibility though considerable power is aligned behind our current model and we behave as if they are fixed and unchangeable.   (See this PDF to understand how far our economic ideas have strayed from the thinking and goals of the ancient Greeks.)  The Greeks rightly recognized the economy as the engine of the ‘household’ and society, the system that, through nature’s largesse and human labor, creates that which sustains us.  It is necessary that an economy be regulated through rational decision making.  Such a system ‘freed’ of its responsibility to society to move it in a beneficial direction, is more likely to simultaneously squander its world and resources while failing to meet the needs of its people and the many species that comprise it.  The Greeks understood that by not limiting the pursuit of luxury the capacity of nature to fulfill its demands would be compromised.

This last year has driven this point home for me as the pandemic and our divisive politics, both plagues on this world, work to drive us apart.  These compound the ever increasing gap between the rich and poor, stranding ever more of the middle class on their own as well.  We’ve conflated what we want with what we need and released individual greed to pursue its ends freely.  I have been studying the topics of evolution, natural selection, random mutation and the role of energy in life, acting as a driving, creative, force behind evolution, increasing complexity and the self-organization of organisms, which in the world of physics are recognized as far out of equilibrium, dissipative structures, taking higher quality energy in, utilizing it in their growth and metabolism, before exhausting it outside of their ‘bodies’.  Organisms have the ability to self-catalyze, reproduce and maintain themselves as long as energy flows through them uninterrupted.  These phenomenon lend weight to our understanding that life is not a random occurrence, there is something inevitable about it, the underlying physics and chemistry of the universe pushing the process.  Organisms are living, self-reinforcing, complex ‘nested’ systems, each composed of successful, dynamic patterns, that repeat in innumerable forms, between very narrow limits.  Organisms exist in the ‘moment’ along the energetic cusp between life and death, that sweet spot within which our chemistry and metabolism remain, between sub-critical and supra-critical states, stasis and conflagration.  There are countless lessons for us to learn from biology that we can apply to our own lives, because life is not an accident, nor is it a singular miraculous event…it is rooted within and powered by the forces of nature.

We exist within a complex network of organisms, a network of self-sustaining systems, made possible and animated by the flow of energy as it moves from low to high entropy, from order to randomness, sunlight ‘becoming’ living tissue, feeding successive trophic levels, endlessly cycling.   All of life exists in this singular moment entirely dependent upon the health and vitality of the whole, the process of which each individual is a part, with a role to play, which effects every living thing and of what will follow.  Through our broader economic behavior we have set ourselves outside of this essential process of nature.  We cannot know ultimately where this will take life, but we do know, with some confidence, that if we interrupt or compromise it, we put everything at risk.

What Do We Do When the Whole World Feels Like its Falling to Pieces?

In this blog I focus on plants.  Any gardener, botanist or horticulturist knows that plants, all living organisms, live in an incredibly complex, interwoven network of systems, each affecting the others, the health of anyone, in large part determined by the health of the ‘whole’.  Life does not and cannot exist in a vacuum.  We humans are also very much living organisms and subject to the same kind of limits as any species.  What we build and produce, including those more abstract things like our social and economic systems upon which we are very much dependent, are subject to the same natural laws and limits, whether we recognize them or not.  Very much a part of this is how we value other life collectively.  Just because many may say other people and species are of less value, does not make this fact.  The laws and ways of ‘man’ must remain within, and consistent with, the laws of nature.  We are not at liberty to treat other life as expendable.  We owe a debt and responsibility to all life.  Life permits and supports us so it is incumbent upon us to do the same for it.  Such is the natural law of reciprocity.
