The Much Maligned Western Juniper: The Role of Juniperus occidentalis in Central Oregon

Leave a reply

Old growth Junipers near Cline Buttes. These two rooted down long ago on top of this lava flow. Much of the lavas here were produced during the Deschutes Formation over many thousands of years more than 5 million years ago. Surface lavas, cliffs and slopes define the area with a few sediment filled basins dominated by Sagebrush and Bitterbrush.

The Western Juniper is the  singular native tree of Dry Canyon and the immediate Redmond area. I grew up with it here in Central Oregon. When we moved here in ’61 i remember driving north after passing through miles and miles of various Pine forests, which eventually yielded, riding in our VW bus, as we left Bend. Bend sits within the ecotone, the relatively narrow transition zone, between Ponderosa Pine forest and Juniper steppe. What were these trees? Coming from California’s Salinas Valley, the landscape could hardly be more different to a six year old. So different in form and detail, Junipers squatted darkly across the landscape, nothing like the tall, majestic Pines or Oaks I was more familiar with or even the Lodgepole Pine we drove through across the pumice plain of the LaPine area.

Weeds: What We Need to Do at DCVS

Leave a reply

Looking NE from the gate at Northwest Way, other than a handful of juvenile Juniper there is literally nothing native of value across this roughly 9 acre spread. The other two undeveloped phases are equally bad, having a similar mix of weeds.

The question I keep hearing is, ‘What do we do?’ Many, if not most people living here now, have expressed frustration and more about the Dry Canyon Village South, DCVS’s, landscapes, specifically the berm, the mini-parks,  the Circle and the 25+ acres of undeveloped, uncared, for property we share space with. They ask me because they know I cared for Park landscapes, as a field horticulturist, for almost 30 years, Parks which often included natural areas of over 100 acres, to little neighborhood parks and intensively developed and used urban parks in the downtown core. I also haven’t been shy about my criticism of the lack of care, or of even a plan, for the neglected property we are saddled with. Anyone who has cared for a landscape can see the problem here. Leaving disturbed and neglected properties on their own is not a plan and can lead only to their further deterioration and continuing, worsening, ‘weed pressure on the adjacent developed landscapes.

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

Leave a reply

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

Leave a reply

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.

April 14, 2024

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

Leave a reply

[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 →

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

Leave a reply

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.

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

1 Reply

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 →

The Owls of the Eastern Ice:A Quest to Find and Save the World’s Largest Owl, Jonathan Slaght, a review

Leave a reply

Slaght holding one of the Blakiston's Fish Owls they captured and released.This is a story about the effort to understand and protect Blakiston’s Fish Owl, the largest owl in the world and its endangered population living in the Russian territory of Primorye Krai which lies along the Sea of Japan, north of the Russian port city of Vladivostok. It is a remote, sparsely settled and wild place, isolated from the rest of the world, and Russia as well, at a latitude close to our own, stretching 559 miles, between 42º and 48º north latitude. The author, Jonathan Slaght, a PhD candidate at the time, spent years in Primorye first in the Peace Corps and later working on a variety of wildlife projects before he took on the owls, a several years long study he undertook in association with the University of Minnesota, teaming up with Russian experts, and a loose international group of others doing research on other species resident there, like the Amur Tiger. His crew of Russian field workers, most of them hunters, skilled sportsmen, skilled as well in traveling through the wild landscape and survival there, were invested in the work they were doing. These people become his friends over the several years, despite or maybe because of their quirks, while both assisting and ‘training’ him as they do their primarily winter field work, under very harsh and often dangerous conditions, gathering data in the long months he spent back in the US. Along the way he lays out the work he must do to create an effective conservation plan, the goal of which was to secure the owl’s future, an owl about which relatively little was known.

Fen, Bog and Swamp: A Short History of Peatland Destruction and Its Role in the Climate Crisis , a Review

Leave a reply

For another review: link

Novelist Annie Proulx, begins her book with her childhood, giving us an idea of who she is, her attachments to the living world. She takes us with her on a walk she took with her mother as a young girl, through the neighborhood wilds, to an ignored patch of swampland. Her mother loved such places. She places her story in the larger story of the times of her birth and coming of age, of the 1930’s and the cruelties we perpetrated on each other and our limited view of the natural world, a world set as a table before us, for our consumption. She writes of her attachments to these abused and devalued wet landscapes, their necessity for a healthy natural world and what their loss means. Earlier, I reviewed Edward Struzik’s book “Swamplands”. Struzik has spent years working with researchers and conservationists in the field, and writing of his experiences. Proulx’s approach is much more personal as she works to place bogs, fens and swamps into a human, historical and cultural context.

Swamplands: Tundra Beavers, Quaking Bogs and the Improbable World of Peat, a Review

Leave a reply

The idea of individuality and control, key elements of the American psyche, are a self-deception. We can take an individual action, guided by an intention, and see its effect in the world around us, but after that, the first ‘tier’ of effects, there are secondary, tertiary and others beyond them, as what we have effected spreads out across space and time, effecting those things, beyond our focus, that nevertheless are in relationship, and do and must respond. If we’re paying attention we can see them and attribute them to others, unaware of our impact. The world is so large and complex, while we individually, commonly see ourselves as relatively ineffectual. We often don’t recognize our own agency and how collective effects propagate from our action. This can also support the idea we ‘can’t’, in a significant way, damage the systems and cycles that support life on Earth. What we must understand though is, that as members of societies and cultures, which share economies and technologies, our ‘individual’ actions are ‘shared’, they are multiplied, often many millions of times. We act individually, but we have tremendous collective impacts. By denying this we deny individual responsibility, which in effect, is a cultural denial, permitting the negative impacts to continue. “It’s just me!” “It doesn’t matter.” “It’s their responsibility, not mine!” These collective problems are then left unaddressed.

It is easy to believe this way. There is so much beyond our own control, so many problems, that it must be this way right? No. We are responsible, collectively. We never truly act independently, because we live in relationship with those around us and their, and our, influence over one another blur. Like it or not, we are a part of a larger society. To go against the conventions and norms of society, to act independently, is risky, to ourselves and the world around us…a risk which can bring with it changes, either positive or destructive. However, going ‘along with’ the norms and conventions of society, unquestioningly, is to possibly continue a potentially destructive practice. We are responsible. We have necessary roles o play. We have been relatively bad as a society at discussing our wider actions, of working to understand our impacts and insuring the security of life and its necessary conditions. Too often we comply, go along and continue doing those things simply because we ‘always’ have, forgetting that as our numbers and use continues to grow, so does the potency of our impact. We have been habitually confusing short term gain and comfort, with longer term survival and good. The consequent results of those unexamined actions can become devastating. To continue ignoring our negative impacts on others, in its broadest sense, is ultimately a threat to our own well being and security. Uninformed actions, actions taken selfishly at other’s expense, threaten the whole, because of the ubiquitous and pervasive connections to the world and between all people, places and organisms. Our denials will not change this. So, why do I bring this up? This is a gardening/horticultural post…because, what we do, or don’t do, in our gardens and across our shared landscapes, has impacts well beyond their borders. Continue reading →
