Oregon - Tree Identification


Western cascade forest, definitely was planted. In a clearing in the forest along with some western red cedars. I couldn't find anything that would match it when looking for native Oregon trees.


I'm thinking this is a Taxus brevifolia, otherwise known as a "Western Yew". They're most commonly found in the northwest region of the United States; so, even if the tree was planted, it's quite probable that it was still acquired (somewhat) locally.

I had a difficult time finding an image that so directly matches the bark image you provide, just from where that tree is so young, but I was able to find a matured version of the tree, which still has a similiar color and bark pattern. I believe that when the tree matures, the vien-like bark sheds, which results in the "scarring" that can be seen in the following image.

And then here's a few images that show the foliage. Notice the similarities in how the pines flare out, and the coloration of the branches. Once your tree matures, it'll get darker in color and develop small red berries, as can be seen in the following images.

The mature tree is on the left, and the right is still developing (which is most accurate to your images).

There is a small chance that the species provided by this answer is inaccurate, but I'm sure it's at least within the Taxaceae family.


Department of Integrative Biology

The Tree of Life Web Project (ToL) provides information on the Internet about our current knowledge of the evolutionary tree of life and associated information about characteristics and diversity of life on Earth. Development of this open-access, database-driven system began in 1994 its official release was in 1996. Core scientific content in the project is compiled collaboratively by more than 540 biologists, all experts in particular groups of organisms, from over 35 countries. Additional learning materials are contributed by over 200 students, teachers, and amateur scientists, while images, movies, and sounds are contributed by both of these groups and over 200 media-only contributors. Administration of the project follows a hierarchical, community-based model, with authors for different parts of the ToL chosen by the scientists working in that particular field. The goals of the project are to document all species on Earth, as well as all significant clades to provide basic information about the phylogeny of life to share this information with other databases and analytical tools and to encourage understanding and appreciation for biodiversity, evolution, and the interrelationships of Earth's wealth of species. Here we provide an outline of the goals and history of the project the current content, administration, architecture, contributors, and audience, the challenges we have faced, and the future of the project.


Slug Portal

The most economically important species of slug (> 90%) in the Pacific Northwest that is most associated with damaging field crops is the gray field slug (or commonly called the gray garden slug), Deroceras reticulatum, Müller. This slug species can be found in cultivated areas such as agricultural field crops, backyard gardens, roadside, parks, and meadows. This slug is much less common in natural habitats (e.g., forests). It is native to Europe, North Africa and the Atlantic Islands. The European red slug, Arion rufus, and over the last 10 years, the brown-banded Arion, Arion circumscriptus, the black greenhouse slug, Milax gagates, the large spotted garden slug, Limax maximus, the marsh slug, Deroceras laeve, and the native reticulated slug, Prophysaon andersoni, have also become important pests.

There are differences in activity patterns (seasonal, as well as responses to weather changes) and environmental/ecological factors (temperature, moisture, food preferences) between slug species. It has been noted that some Arion species are less active on soil surface, feed more on humus, decaying leaf mold, and vegetation, and prefer temperatures greater than 40 °F, compared to D. reticulatum, that can be active at lower temperatures in the winter, and is a surface feeder.

Taxonomy of slugs has traditionally been based on thier external and internal morphology. In many cases, adult slugs need to be dissected and genitalia examined to confirm species. There are over 40,000 species of Gastropods.

Landscape Plants

This search system employs a plant data base and a series of filters each filter removes plants from the initial list which lack the particular characteristic selected. For example, selecting the characteristic “white/gray” under flower color results in a list of plants that have this characteristic, plants not having “white/gray” flowers are removed from the list. As plant characteristics are selected in a step-wise fashion, the number of plants meeting these criteria will decrease. When all the characteristics of an unknown plant are selected in a given search, the list of plants, hopefully, will be small enough to allow the user to examine the images and information of each listed plant to determine if any appears to match the unknown. The user is encouraged to select the appropriate characteristics one at a time and observe the effect each has on the plant list.

Woody Broadleaf

Pertaining to plants having broad or relatively broad leaves, rather than needle-like or scale-like leaves. Examples of broadleaf plants are apple, ash, elm, maple, oak and rhododendron. A few in this category have very narrow leaves (e.g., rosemary, grevillea) but are not conifers so are included in this category.

Woody Conifer

Any of various mostly needle-leaved or scale-leaved, chiefly evergreen, cone-bearing (or similar) gymnosperm trees or shrubs such as arborvitae, cedar, cypress, juniper, fir, pine, spruce and yew.


Redwood Reproductive Biology

Redwood is a very large tree but the flowers are tiny, separately male and female (evergreen monoecious tree), and develop on different branches of the same tree. The fruits grow into broadly oblong cones on branch tips. Small redwood female cones (.5 to 1.0 inches long) become receptive to male pollen, which is shed between late November and early March. This cone is very similar to baldcypress and dawn redwood.

Seed production starts at about age 15 and increases in viability for the next 250 years, but the seed germination rate is poor and seed dispersal from the parent tree is minimal. So the tree best regenerates itself vegetatively from root crowns and stump sprouts.

Seeded or sprouting young-growth redwood growth is nearly as spectacular in attaining size and wood volume as old-growth. Dominant young-growth trees on good sites can reach heights of 100 to 150 feet at age 50 years and 200 feet at 100 years. Height growth is most rapid up to the 35th year. On the best sites, height growth continues to be rapid well past 100 years.

Strange but True: The Largest Organism on Earth Is a Fungus

Next time you purchase white button mushrooms at the grocery store, just remember, they may be cute and bite-size but they have a relative out west that occupies some 2,384 acres (965 hectares) of soil in Oregon's Blue Mountains. Put another way, this humongous fungus would encompass 1,665 football fields, or nearly four square miles (10 square kilometers) of turf.

The discovery of this giant Armillaria ostoyae in 1998 heralded a new record holder for the title of the world's largest known organism, believed by most to be the 110-foot- (33.5-meter-) long, 200-ton blue whale. Based on its current growth rate, the fungus is estimated to be 2,400 years old but could be as ancient as 8,650 years, which would earn it a place among the oldest living organisms as well.

A team of forestry scientists discovered the giant after setting out to map the population of this pathogenic fungus in eastern Oregon. The team paired fungal samples in petri dishes to see if they fused (see photo below), a sign that they were from the same genetic individual, and used DNA fingerprinting to determine where one individual fungus ended.

This one, A. ostoyae, causes Armillaria root disease, which kills swaths of conifers in many parts of the U.S. and Canada. The fungus primarily grows along tree roots via hyphae, fine filaments that mat together and excrete digestive enzymes. But Armillaria has the unique ability to extend rhizomorphs, flat shoestringlike structures, that bridge gaps between food sources and expand the fungus's sweeping perimeter ever more.

A combination of good genes and a stable environment has allowed this particularly ginormous fungus to continue its creeping existence over the past millennia. "These are very strange organisms to our anthropocentric way of thinking," says biochemist Myron Smith of Carleton University in Ottawa, Ontario. An Armillaria individual consists of a network of hyphae, he explains. "Collectively, this network is called the mycelium and is of an indefinite shape and size."

All fungi in the Armillaria genus are known as honey mushrooms, for the yellow-capped and sweet fruiting bodies they produce. Some varieties share this penchant for monstrosity but are more benign in nature. In fact the very first massive fungus discovered in 1992&mdasha 37-acre (15-hectare) Armillaria bulbosa, which was later renamed Armillaria gallica&mdashis annually celebrated at a "fungus fest" in the nearby town of Crystal Falls, Mich.

Myron Smith was a PhD candidate in botany at the University of Toronto when he and colleagues discovered this exclusive fungus in the hardwood forests near Crystal Falls. "This was kind of a side project," Smith recalls. "We were looking at the boundaries of [fungal] individuals using genetic tests and the first year we didn't find the edge."

Next, the microbiologists developed a new way to tell an individual apart from a group of closely related siblings using a battery of molecular genetic techniques. The major test compared fungal genes for telltale signs of inbreeding, where heterozygous strips of DNA become homozygous. That's when they realized they had struck it big. The individual Armillaria bulbosa they found weighed over 100 tons (90.7 metric tons) and was roughly 1,500 years old.

"People had ideas that maybe they were big but nobody had any idea they were that big," says Tom Volk, a biology professor at the University of Wisconsin&ndashLa Crosse. "Well it's certainly the biggest publicity that mycology is going to get&mdashmaybe ever."

Soon afterward, the discovery of an even bigger fungus in southwestern Washington was announced by Terry Shaw, then in Colorado with the U.S. Forest Service (USFS), and Ken Russell, a forest pathologist at Washington State Department of Natural Resources, in 1992. Their fungus, a specimen of Armillaria ostoyae, covered about 1,500 acres (600 hectares) or 2.5 square miles (6.5 square kilometers). And in 2003 Catherine Parks of the USFS in Oregon and her colleagues published their discovery of the current behemoth 2,384-acre Armillaria ostoyae.

Ironically, the discovery of such huge fungi specimens rekindled the debate of what constitutes an individual organism. "It's one set of genetically identical cells that are in communication with one another that have a sort of common purpose or at least can coordinate themselves to do something," Volk explains.

Both the giant blue whale and the humongous fungus fit comfortably within this definition. So does the 6,615-ton (six-million-kilogram) colony of a male quaking aspen tree and his clones that covers 107 acres (43 hectares) of a Utah mountainside.

And, at second glance, even those button mushrooms aren't so tiny. A large mushroom farm can produce as much as one million pounds (454 metric tons) of them in a year. "The mushrooms that people grow in the mushroom houses&133 they're nearly genetically identical from one grower to another," Smith says. "So in a large mushroom-growing facility that would be a genetic individual&mdashand it's massive!"

In fact, humongous may be in the nature of things for a fungus. "We think that these things are not very rare," Volk says. "We think that they're in fact normal."
