Quaking Aspen Populus tremuloides Young aspen grove. Photo by Linnea Hanson. Aspen are medium-sized deciduous trees, commonly 20 to 80 feet in height, and 3 to 18 inches diameter.
Trees more than 80 feet tall and larger than 24 inches diameter are occasionally found. Their bark is smooth, greenish-white, yellowish-white, yellowish-gray, or gray to almost white in color. The green color is from chlorophyll in the bark. Their bark may become rough and fissured with age.
They are pointed at the apex and rounded at the base, with many small rounded to sharply pointed teeth along their margins. Aspen leaves are smooth, bright green to yellowish-green, dull underneath, until they turn brilliant yellow, gold, orange, or slightly red in the fall.
The flattened stem allow the leaves to quake or tremble in the slightest breeze; hence, their name. The leaves of young sucker aspens may be much larger, sometimes 7 to 8 inches long. Aspen trees usually do not live more than years, though they may persist more than years.
It grows on many soil types, especially sandy and gravelly slopes, and is quick to pioneer disturbed sites where there is bare soil. It grows best where soils are moist and sunshine is plentiful. Aspen is intolerant of shade, and does not compete well with more shade-tolerant conifer species.
Quaking aspen is an aggressive pioneer species. It readily colonizes burned areas and can persist even when subjected to frequent fires. In the Central Rocky Mountains, the extensive stands of aspen are usually attributed to repeated wildfires. It may dominate a site until replaced by less fire-enduring but more shade-tolerant conifers.
The southern-most aspen are found in central Mexico. Quaking aspen is the most widely distributed native North American tree species, growing in greatly diverse regions, environments, and communities. It occurs across Canada, through the United States, to Mexico, in a variety of habitats. In the western United States, aspen is generally found at 5, to 12, feet elevation.
Aspen occurs in extensive pure stands in some areas, while in others, it is a minor component of the forest landscape. Most of the aspen forest in the United States is found in Utah and Colorado, though it is also scattered throughout all of the western states.
Aspen provide habitat for a wide variety of wildlife, including hare, moose, black bear, elk, deer, ruffed grouse, migratory birds, and a variety of smaller animals.
Aspen stands produce livestock forage, biomass, and are a source for a variety of wood products. Aspens are visually appealing, as they provide contrast to the dark conifers during all seasons; and in the autumn, tourists come to the West to see the brilliant fall colors of the aspen groves.
Reproduction Aspen reproduces both by seeds and by root sprouts, though sprouting is the most common and successful form of reproduction. Aspen produces small flowers, on catkins that are inches long. These flowers are produced in the early spring before the leaves grow on the trees.
Aspen is dioecious, with male and female flowers normally borne on separate trees. The catkins produce small fruit that split to release lots of tiny, cottony seeds that are dispersed by the wind. Germination occurs within a couple days of dispersal provided the seeds reaches a suitable moist seedbed.
Quaking aspen female catkins. Aspen is noted for its ability to regenerate vegetatively by shoots and suckers arising along its long lateral roots.Poison frogs, also called poison arrow and poison dart frogs, are the most brightly colored frogs in the world.
They live in wet, tropical forests in Central and South America where their diet contributes to the toxins they secrete through their skin.
The Actinodiscus malaccensis species is also known as the Metallic Mushroom or Green Metallic Mushroom, and can be a very attractive mushroom indeed. These mushroom corals come in brown, green, gray or beige-brown and they have little short tentacles that can be a combination of these colors.

Learn more about these blooms and the health risks they can pose. Blue-green algae are most often blue-green in color, but can also be blue, green, reddish-purple, or brown.
Blue-green algae generally grow in lakes, ponds, and slow-moving streams when the. The green color is from chlorophyll in the bark. Their bark may become rough and fissured with age. Aspen leaves are are thin, firm, and nearly round, 1 1/2 to 3 inches diameter. Significance. Plastics are a contaminant of emerging concern accumulating in marine ecosystems.
Plastics tend to break down into small particles, called microplastics, which also enter the marine environment directly as fragments from a variety of sources, including .
