Not all Christmas trees are created equal. The most common types of Christmas trees are the Douglas fir, grand-fir, and noble-fir, and each has unique characteristics that separate one from the other. If you are planning a nature hike or Christmas tree picking day this holiday season, look for the book Trees to Know in Oregon and Washington by Oregon State University professor emeritus, Ed Jensen.
The OSU Extension Services piece describes each tree in detail so you are able to identify them in the wild – or at the Christmas tree farm.
“The stories include identifying characteristics and ecology, natural history and cultural uses, and regions and locations where each tree can be found,” said Jensen.
The identification key helps readers to decipher a Douglas fir – the most common Christmas tree type – from similar trees like conifers and other firs. However, if you are picking your tree from a farm or parking lot setting, keep in mind that there will likely be many foreign species such as Nordmann and Turkish firs that are not included in the book. Jensen added that you might also find native pines like sugar or western white or native spruces like Sitka and Engelmann.
As a reminder, if you plan to collect a Christmas tree from the wild, Oregon prohibits tree cutting in state forests. Additionally, you will need to acquire a permit from the U.S. Department of Forestry. Bringing the book along on your search will also prove helpful in identifying your perfect tree, which details and illustrates over 125 trees. Jensen, who took most of the book’s photos himself, includes a story with each tree that depicts the tree’s history, unique characteristics, and functions.
The book is conveniently sized for taking along on hikes, can be purchased through the OSU Extension catalog, and the new edition marks its 70th anniversary.
Some important reminders for picking your tree include:
–Ensure needles are attached to the base
-Ensure needles are not dry or are not easily broken
-Ensure branches, particularly the smallest ones, are pliable.
Since picking your perfect Christmas tree is only the first step, it is important to care for your tree after it enters its new home. Some at-home care tips include:
– Cut a slit into the trunk to allow water to enter
– Cut off the base and soak in a container of water if the tree won’t be set in its stand immediately
– Use a tree stand that fits your tree
– Keep your tree hydrated with fresh water with nothing added
– Keep your tree away from heat sources
Note that different tree species vary greatly in their shelf lives. While Douglas firs cost less and smell “like Christmas,” they, unfortunately, do not last nearly as long as Nordmann, Turkish, or Noble, which can last an entire month if cared for properly.
