conifer – What Tree Where

Austrian pine (Pinus nigra) was introduced to North America in 1759. This two- needled evergreen, also called European black pine and common black pine, is native to Europe and Asia.

Quite possibly this species should hold a place of honor in American history. Due to its heartiness, wind tolerance, and ability to grow in poor soil, during the Franklin D. Roosevelt administration the U.S. Forest Service was tasked with planting 222 million trees across the Great Plains to combat the effects of the Dust Bowl. As the Arbor Day Foundation reports, these trees have thrived for more than 75 years in some of the poorest planting conditions in our country. Although this conifer is now susceptible to many more diseases and pests, according to The Tree Book* it is an inexpensive tree which is often planted in areas too small for its eventual size.

The Wood Database says Austrian pine is easy to work with but its primary use has been as pulp for the paper industry. It may also be used for boxes and crates. Like most pines, its resin has many medicinal uses, including fighting respiratory ailments, kidney problems, and for poultices, plasters, and steam baths.

P3310036 — The bark and branches of the Austrian pine

According to The Christmas Tree Growers Association of New York, the tradition of a Christmas tree originated in Germany and became popularized in England when Queen Victoria and Prince Albert had a tree placed in Windsor Castle. At one time Austrian pines were used as holiday trees in the U.S. Their usage has fallen out of favor, possibly because of the shearing needed for a perfect shape. Its branches don’t fill in until the trees are at least ten years old and it develops more slowly than the Scotch pine. Smaller homes than those of the 1800 and early 1900s might also have caused the large pine to fall out of favor. Its spaced and heavy branches were useful for those with large ornaments and lots of room. Still, at least thirteen Christmas tree farms list Austrian pine as one of their selections. Although only moderately fragrant, the trees hold their needles well. The main drawback from the growers’ perspective might be the trees aren’t as resistant to pests as other species and may be more difficult to ship.

The tallest Austrian pine, over 155’tall, grows in Montenegro, while the oldest, in Austria, is thought to be around 1000 years of age. In the U.S. the Champion tree grows in Washington state. In Colorado, the overall largest tree is found in Greeley. Its height is half of the world champion.

To find 154 Austrian Pine (Pinus nigra) in City Park, look along Jackson Street where Magnolia Street intersects. If Magnolia went through the park, it would cross a small cluster of conifers. Of the three trees, the large tree with more of a rounded top should be the Austrian pine. p3310016-1

What kind of tree do you think of when someone says natural Christmas tree? I suspect many of us think of a pine tree. Oddly, the most common trees used aren’t pines but firs and spruces. Pines do make the list of common or best trees, but only a few species are routinely used. In England the lodgepole pine is mentioned as a choice! In the U.S. two or three species are mentioned, probably dependent on what part of the country you live in.

Eastern White Pine (Pinus strobus) — Eastern White Pine

Eastern White Pines (Pinus storbus) are native to North America and found from Minnesota south to Arkansas and east. This is the state tree of both Maine and Michigan. Considered the tallest native pine in the east, modern day trees are dwarfed by other trees in the genus, such as the Ponderosa and sugar pine. The single largest specimen, which can be found in Maine, is 132′ tall and has a circumference of 229 inches. The normal life expectancy of this species is about 200 years, although a fossilized log found in Ontario included 407 rings.

Most of the virgin forests have been logged, although the species is planted for reforestation. White pine timber has been used to build boats, furniture, and buildings. In the 1700s the trees were harvested to provide masts for the Royal Navy, thus leading to the Pine Tree Riot of 1772.

Beyond their use as building materials and firewood, the white pine provided resin in the building of canoes. The sap was used as an antiseptic and chemicals found in white pine may still be used as ingredients in anti congestion medications. The Healing Power of Plants website also includes the information that a component chemical in white pines may be useful in combating LDL cholesterol. At least one site mentions the seeds were used to cure meats, and the cambium could be ground into a flour. This was used by both early settlers and Native American populations. Early blackboards were often made of white pine painted black.

The Eastern white pine is usually included on lists of trees sold for Christmas. One possible advantage to its use is it tends to hold onto its needles longer than other conifers.

They also have little aroma, which makes them a good choice for those who have sensitivities. But they are very full, bushy trees and their branches cannot accommodate heavy ornaments.

A white pine has only been used as the Capitol Christmas tree, also known as the People’s tree, twice in the fifty-four year history of the program. In both 1968 and 69 PARTs of an Eastern white pine were used. Although still listed as being a species used as a Christmas tree, even in Michigan it seems to have fallen out of favor. A recent study rated it #7 in acreage planted.

To find this (164) specimen, head to the southwest corner of City Park and Mulberry. It should be easy to find between the two handicapped parking signs seen in the photo above.
