Fads come and go. Many can be good, even if only briefly. A few might be bad enough to later stigmatize the object of the fad. For example, the formerly esteemed crape myrtle is now familiar as a mundanely common tree.

Flashy bloom and complaisance contributed to its excessive popularity. Most sorts of juniper are similarly victims of their previous fad.

A few cultivars of juniper suddenly became overly popular during suburbanization of the 1950s. They were remarkably reliable and resilient. Most were shrubbery or low hedges. A few were groundcover.

Hollywood juniper grew as a compact sculptural tree. However, most junipers grew too big. They became difficult to maintain, or impossible to renovate.

As many outgrew suburban gardens, few junipers outgrew their reputation. Even modern cultivars that were unavailable during the fad of the 1950s are perhaps less popular than they should be. Realistically, many old and new cultivars of juniper are quite practical for refined home gardens. They merely need to be appropriate to their particular application.

Many cultivars of several species of Juniperus are commonly available. Straight species are very rare from nurseries, although a few are native nearby.

All junipers are evergreen with tiny awl or scale leaves. Foliar color ranges from forest green to silvery gray. Bloom is unremarkable. Some junipers produce pretty and aromatic blue, gray or black berries.

Junipers generally do not respond favorably to pruning that damages their natural forms. Those that grow as groundcovers, with stems that sprawl over the surface of the soil, are not offended by pruning to contain their edges. However, most groundcover junipers are actually just low shrubbery. Pruning might leave holes within their dense foliar canopies.

Junipers that grow as small trees do not mind removal of lower limbs at their main trunks, but object to partial pruning or 'stubbing' of such limbs. Regardless of their natural forms, all junipers should be proportionate to their particular applications.

With sufficient space, they can mature and develop their naturally distinguished forms with minimal altercation. Maintenance could really be quite minimal.

Rocky Mountain juniper

Hollywood juniper had formerly been the only popular juniper of tree form. As it became less popular during the past few decades, cultivars of the once obscure Rocky Mountain juniper, Juniperus scopulorum, became more popular.

Also, a few more modern cultivars became available. Now, the once overly common Hollywood juniper is quite uncommon.

Rocky Mountain juniper is naturally rather grayish for protection from the harsh exposure of the high elevations which it inhabits. Cultivars are grayer, bluish or silvery, and mostly develop symmetrically conical form.

Old specimens that were initially conical eventually grow as small trees with rounded and relatively dense canopies, perhaps on bare trunks.

'Skyrocket' and 'Blue Arrow' are very narrow like Italian cypress that grow only 15 feet tall. 'Wichita Blue' and 'Moonglow' are stoutly conical. 'Blue Arrow' and 'Wichita Blue' are bluish green. 'Skyrocket' and 'Moonglow' are silvery gray.

Established specimens do not require much water, but develop better foliar color with warmth and occasional watering.

Killexams : Four of five pinyon-juniper tree species declining in their ranges in the West

Pinyon-juniper woodlands host unique wildlife and wildlife habitat, as well as areas for hiking and outdoor recreation. They are also part of a web of healthy ecosystems that, together, help to balance water availability, storage and runoff; and prevent erosion. A new study published in Global Ecology and Biogeography and led by University of Nevada, Reno researcher Robert Shriver sheds new light on what is happening in pinyon-juniper woodlands across the West. The research is unique, in that it looks at both tree mortality, as well as recruitment, or new seedlings and saplings, to calculate a "net effect." And, the news isn't necessarily good, particularly in warmer, drier locations.

"We found that four of the five species were declining," said Shriver, an assistant professor in the University's College of Agriculture, Biotechnology & Natural Resources. "And, in the driest, warmest locations, up to about 50% of populations are declining. It's pretty severe in those locations, which are usually at that tend to be hotter and get less water than woodlands at higher elevations."

Shriver said that when looking at all locations studied, which included over 6,000 plots and more than 59,000 tagged trees, up to 10-20% of populations were declining. Of the five species, including two pinyon pines and three junipers, Pinus edulis, more commonly referred to as two-needle pinyon or simply pinyon, showed the greatest declines, with about 24% of its populations in decline. The other pinyon species and two of the juniper species showed more moderate declines overall, but still quite severe declines in the hotter, drier areas. These species include Pinus monophylla (single-leaf pinyon), Juniperus monosperma (one-seed juniper) and Juniperus scopulorum (Rocky Mountain juniper). Juniperus osteosperma (Utah juniper) was the only species that did not show a decline.

"Utah juniper was the exception to everything," Shriver, who conducts research as part of the College's Department of Natural Resources & Environmental Science and Experiment Station, said. "What we found pretty much matches up with what we know about that species' resiliency. It's the most abundant in the Great Basin, and is typically less vulnerable to hotter, drier climate conditions, so it could mean that there might be compositional shifts occurring in the future, where some areas that are mixed species might become more juniper-dominated."

Gathering the data and building the models

In part, Shriver used data from the Forest Inventory and Analysis, a nationwide survey of forested lands in the U.S., conducted by the U.S. Forest Service.

"They tag the trees and return to the same plots for comparison at least every 10 years, but they have a systematic scheme to determine where," he explained. "They are making sure they are getting a broad sample of both federal and private land. The result is a representative sample of what all forests look like across the U.S., even covering some very remote locations. It's staggered, with 10% of plots surveyed in a given year."

Shriver said the plots that were included in this pinyon-juniper research were first sampled between 2000 and 2007, and were surveyed the second time between 2010 and 2017. It is data obtained within those 10-year spans that he used for the research. He pointed out, however, that the Forest Service survey doesn't capture as complete data on recruitment, or seedlings, since they don't tag anything under 1 inch in diameter. Trees of this size are counted, but not tagged.

"Recruitment is the really hard part," he said. "Tree mortality is easy to see, but recruitment is harder to observe, so it's been harder to account for. Having a stable population is dependent on both mortality and recruitment. So, we developed a new statistical approach that allowed us to understand and factor in recruitment. Using these modeling approaches, we were able to quantify what the recruitment rate is in these different areas, and then combine that data with the mortality data to get a more clear, accurate picture of what is really going on in terms of change in species' populations under different climate conditions and woodland densities in different regions."

The research excluded plots where fire mortality or intentional tree harvesting occurred, allowing the researchers to more directly observe changes occurring due to climatic conditions across each species' range.

Impacts of the findings

Shriver says the declines in populations they calculated could be significant for a number of reasons.

"In regard to wildlife, probably the most significant effect is on the pinyon jay, which has been in decline for the last couple of decades, and is really dependent on the seed that is produced by pinyon pine," he said. "The areas where the pinyon jay tends to choose are on that border of the sagebrush and the pinyon. It likes those habitats that are probably the most vulnerable. But, beyond the pinyon jay, certainly a number of species could be affected—mule deer, and other birds and wildlife."

In addition, Shriver said pinyons and pine nut harvesting are culturally important, to Native Americans and others, and pinyon-juniper woodlands provide recreational value for hikers and outdoor enthusiasts. Importantly, he adds, there's the functions that pinyon-juniper woodlands play in our watersheds. Pinyon-juniper woodlands play an important role in water and soil retention in some locations.

What does the future hold?

"We are likely to see pretty big changes in where we find forests in the Great Basin and the Southwest over the next few decades," Shriver said. "A lot of places where we saw forests, we may not see them, especially in lower elevations, because they tend to be the hottest and driest."

Shriver said there has been a lot of expansion in these woodlands since the mid-1800s, and that some declines may not be a bad thing everywhere. For example, in some areas the pinyon-juniper woodlands have encroached on shrubland ecosystems that provide important ecosystem services and unique wildlife habitat. And, the trees, especially when packed in too densely and without enough moisture, also increase the intensity of wildfires.

"Our results also suggest that for some locations, management actions could slow down or reverse the woodland declines," Shriver said. "As it gets warmer and drier, the density of trees a landscape is able to support lessens, so reductions in tree density might expand the envelope of where the trees can be, reducing the chance of large events."

While woodland decline could create an opportunity for expansion of native shrublands such as sagebrush, Shriver cautioned that other, less beneficial vegetation could also take hold.

"Just because the pinyon and juniper die off, doesn't mean something desirable would establish in their place," he said. "You might get cheatgrass or other undesirable vegetation."

Shriver said the purpose of the research and models it created is to help anticipate the vulnerability of woodlands and forecast coming range shifts, so that we might be able to sway the outcomes to be more positive ones.

"If we know where this is likely to happen, we can do the best we can to influence what might happen next," he said. "We might be able to direct these into ecosystems that might support native plants and animals in the Great Basin and the Southwest, and fit into our watersheds in a beneficial way."

Killexams : ‘Major incident’ under investigation in Juniper Acres; few details given, structure fire reported in area

(Update: Adding video, comments by Cobain's grandfather, family friend)

'It's like a bad dream that you want to wake up from'

ALFALFA, Ore. (KTVZ) –  “You can’t process this ... you can't process this," Bob Johnson said Monday.

The words of a grandfather struggling to grasp the death of his 6-year-old grandson, Cobain Johnson, and the boy's 9-year-old half-sister, Nyla.

Crook County sheriff's deputies say the two children died early Saturday morning when their home was engulfed by a house fire in the largely off-grid Juniper Acres subdivision of Crook County east of Alfalfa and south of Prineville.

Family friend Brad Deane told NewsChannel 21, “It’s like a bad dream that you want to wake up from."

Deane said he's best friends with Cobain's father and is helping organize the funeral.

He said his own three boys and Cobain played together often.

“I’ve picked him up quite frequently for weekend adventures while his dad was away," Deane said. "We took him to the park, we took him to the fair, we took him to his first movie.”

Johnson said of his grandson, "He loved fishing, he loved the water, he loved soccer."

As they and others struggle through this tragedy, they remind the community how much the whole family is impacted.

Johnson said, “Our thoughts are with the sister and the two surviving children and his mom.”

Deane said, “They have no place to live. They have medical bills, they have, you know, a lot of expenses as well. My main specific point (of creating a GoFundMe page) was to make sure both babies were able to have the proper arrangements, you know right out the gate.”

Dean launched the page where he achieved his goal of raising enough funds to cover funeral costs.

A separate GoFundMe page has been set up on behalf of Danielle Keating, the mother of the two children lost in the blaze.

The type of pain they're all facing, Deane said, is forever.

---------------------------------------------------------------------------------------

Earlier story:

Deputies and firefighters responded shortly before 6 a.m. to the incident off Southeast Cascade Way and Reservoir Road, sheriff’s Sergeant Javier Sanchez said in a news release.

Upon arrival, they found the house engulfed in flames, Sanchez said.

“Most family members safely made it out of the house,” the sergeant said, but “even with the quick response from law enforcement, Fire and Rescue and residents on scene, two children were not able to get out and are deceased due to the fire.”

Sanchez said the children’s names “won’t be released in respect for the family.”

Sanchez said the investigation into the fire is ongoing but that “there is no risk to the public.”

The sergeant thanked all assisting agencies, including Bend Fire and Rescue, the Alfalfa Fire District, Oregon State Police, the Crook County District Attorney’s Office and the Prineville Funeral Home.

“The Crook County Sheriff’s Office would like to extend our thoughts and prayers to the family during this tragic incident,” Sanchez said.

Anyone with information regarding the fire was asked to contact sheriff's Deputy Chris Beard or Sergeant Brian Bottoms at (541) 447-6398, in reference to sheriff’s office Case No. 221128.

Near the ruins of the destroyed home, shocked, grief-stricken residents spoke with NewsChannel 21 on Sunday but did not wish to talk on the record about what had taken place.

Killexams : Four of five pinyon-juniper tree species declining in their ranges in the West

Pinyon-juniper woodlands host unique wildlife and wildlife habitat, as well as areas for hiking and outdoor recreation. They are also part of a web of healthy ecosystems that, together, help to balance water availability, storage and runoff; and prevent erosion. A new study published in Global Ecology and Biogeography and led by University of Nevada, Reno researcher Robert Shriver sheds new light on what is happening in pinyon-juniper woodlands across the West. The research is unique, in that it looks at both tree mortality, as well as recruitment, or new seedlings and saplings, to calculate a “net effect.” And, the news isn’t necessarily good, particularly in warmer, drier locations.

“We found that four of the five species were declining,” said Shriver, an assistant professor in the University’s College of Agriculture, Biotechnology & Natural Resources. “And, in the driest, warmest locations, up to about 50% of populations are declining. It’s pretty severe in those locations, which are usually at lower elevations that tend to be hotter and get less water than woodlands at higher elevations.”

Shriver said that when looking at all locations studied, which included over 6,000 plots and more than 59,000 tagged trees, up to 10-20% of populations were declining. Of the five species, including two pinyon pines and three junipers, Pinus edulis, more commonly referred to as two-needle pinyon or simply pinyon, showed the greatest declines, with about 24% of its populations in decline. The other pinyon species and two of the juniper species showed more moderate declines overall, but still quite severe declines in the hotter, drier areas. These species include Pinus monophylla (single-leaf pinyon), Juniperus monosperma (one-seed juniper) and Juniperus scopulorum (Rocky Mountain juniper). Juniperus osteosperma (Utah juniper) was the only species that did not show a decline.

“Utah juniper was the exception to everything,” Shriver, who conducts research as part of the College’s Department of Natural Resources & Environmental Science and Experiment Station, said. “What we found pretty much matches up with what we know about that species’ resiliency. It’s the most abundant in the Great Basin, and is typically less vulnerable to hotter, drier climate conditions, so it could mean that there might be compositional shifts occurring in the future, where some areas that are mixed species might become more juniper-dominated.”

Gathering the data and building the models

In part, Shriver used data from the Forest Inventory and Analysis, a nationwide survey of forested lands in the U.S., conducted by the U.S. Forest Service.

“They tag the trees and return to the same plots for comparison at least every 10 years, but they have a systematic scheme to determine where,” he explained. “They are making sure they are getting a broad sample of both federal and private land. The result is a representative sample of what all forests look like across the U.S., even covering some very remote locations. It’s staggered, with 10% of plots surveyed in a given year.”

Shriver said the plots that were included in this pinyon-juniper research were first sampled between 2000 and 2007, and were surveyed the second time between 2010 and 2017. It is data obtained within those 10-year spans that he used for the research. He pointed out, however, that the Forest Service survey doesn’t capture as complete data on recruitment, or seedlings, since they don’t tag anything under 1 inch in diameter. Trees of this size are counted, but not tagged.

“Recruitment is the really hard part,” he said. “Tree mortality is easy to see, but recruitment is harder to observe, so it’s been harder to account for. Having a stable population is dependent on both mortality and recruitment. So, we developed a new statistical approach that allowed us to understand and factor in recruitment. Using these modeling approaches, we were able to quantify what the recruitment rate is in these different areas, and then combine that data with the mortality data to get a more clear, accurate picture of what is really going on in terms of change in species’ populations under different climate conditions and woodland densities in different regions.”

The research excluded plots where fire mortality or intentional tree harvesting occurred, allowing the researchers to more directly observe changes occurring due to climatic conditions across each species’ range.

Impacts of the findings

Shriver says the declines in populations they calculated could be significant for a number of reasons.

“In regard to wildlife, probably the most significant effect is on the pinyon jay, which has been in decline for the last couple of decades, and is really dependent on the seed that is produced by pinyon pine,” he said. “The areas where the pinyon jay tends to choose are on that border of the sagebrush and the pinyon. It likes those habitats that are probably the most vulnerable. But, beyond the pinyon jay, certainly a number of species could be affected – mule deer, and other birds and wildlife.”

In addition, Shriver said pinyons and pine nut harvesting are culturally important, to Native Americans and others, and pinyon-juniper woodlands provide recreational value for hikers and outdoor enthusiasts. Importantly, he adds, there’s the functions that pinyon-juniper woodlands play in our watersheds. Pinyon-juniper woodlands play an important role in water and soil retention in some locations.

What does the future hold?

“We are likely to see pretty big changes in where we find forests in the Great Basin and the Southwest over the next few decades,” Shriver said. “A lot of places where we saw forests, we may not see them, especially in lower elevations, because they tend to be the hottest and driest.”

Shriver said there has been a lot of expansion in these woodlands since the mid-1800s, and that some declines may not be a bad thing everywhere. For example, in some areas the pinyon-juniper woodlands have encroached on shrubland ecosystems that provide important ecosystem services and unique wildlife habitat. And, the trees, especially when packed in too densely and without enough moisture, also increase the intensity of wildfires.

“Our results also suggest that for some locations, management actions could slow down or reverse the woodland declines,” Shriver said. “As it gets warmer and drier, the density of trees a landscape is able to support lessens, so reductions in tree density might expand the envelope of where the trees can be, reducing the chance of large tree mortality events.”

While woodland decline could create an opportunity for expansion of native shrublands such as sagebrush, Shriver cautioned that other, less beneficial vegetation could also take hold.

“Just because the pinyon and juniper die off, doesn’t mean something desirable would establish in their place,” he said. “You might get cheatgrass or other undesirable vegetation.”

Shriver said the purpose of the research and models it created is to help anticipate the vulnerability of woodlands and forecast coming range shifts, so that we might be able to sway the outcomes to be more positive ones.

“If we know where this is likely to happen, we can do the best we can to influence what might happen next,” he said. “We might be able to direct these into ecosystems that might support native plants and animals in the Great Basin and the Southwest, and fit into our watersheds in a beneficial way.”

Funding for the study was provided by the United States Geological Survey North Central Climate Adaptation Science Center. Coauthors of the study include Charles B. Yackulic and John B. Bradford, with the USGS Southwest Biological Science Center; and David M. Bell, with the USDA Forest Service Pacific Northwest Research Station.
