The Norway Pine tree (Pinus resinosa)

I'd like to share some information about the Norway Pine tree.  The Latin name for this tree is Pinus resinosa, and it is also very commonly known throughout northeastern North America as the Red pine.  Red pine is probably a better name for common use.  The inner bark of the red pine is very reddish in colour, so it's an appropriate name.  In the field, I usually refer to this tree as the red pine rather than Norway pine.  Most people do.

Speaking of the bark of the tree, here's a photo.  It's quite scaly.  The bark often has more of a grey appearance in weathered trees, but if you peel away the surface bark you'll quickly see the reddish tint underneath.  The reddish bark is also easier to discern in juvenile trees.  Here's a photo showing the bark and trunk of a red pine up close:

The Norway pine is a very majestic tree at maturity.  It can often grow to be more than 30 meters (100 feet) in height and more than a meter in diameter.  Even more impressive, this is a fairly long-lived species, sometimes living for up to five hundred years.

Norway pine has a range which is limited to northeastern North America.  It is commonly found in southern Ontario, Quebec, and through the Maritime provinces.  It is also found in pockets in Newfoundland, and as far west within Canada as southern Manitoba.  It is also common around the Great Lakes and in northeastern parts of the US.  Here's a range map, courtesy of Wikipedia:

Let's go back to the proper name of this tree.  Nobody really seems to be sure why the pine was named after Norway.  It doesn't seem to have any relation to that country.  There's a small town in Maine called Norway, and that town has a lot of red pine around it.  But Norway (Maine) didn't get its name until it was incorporated in 1797, and the original intention was to call it Norage, which was a Native American name for waterfalls.  There doesn't seem to be any information online to hint at when Norway pine started to be called as such, but if it pre-dates the founding of the town of Norway, then it certainly can't be named after the town.  Incidentally, Norway (Maine) was once very famous as the alleged "snowshoe capital of the world."  Red pine was used in the manufacture of snowshoes.  That still doesn't explain the name properly.  I like to pretend that there was once a famous giant lumberjack from Norway with a bushy red beard, and the tree was named after this lumberjack.  But that's unlikely.  It would be a good story though, if it was true.

The Norway pine is a conifer.  Conifers are cone-bearing trees.  The cones of the Norway pine are ovoid in shape, which means that they're egg-shaped.  They're also fairly close in size to regular [chicken] eggs that you'd find at a grocery store, ie. about 5-6cm long when they're still closed.

The needles of the Norway pine are a dark yellow-green, and always come in pairs.  Needles on pine trees always come in pairs, triplets, or groups of five, but the number depends upon the species.  These needles can be fairly long, usually about 15cm or so, and like many other long-needled pines, the needles can be fairly brittle.  Here's a close-up photo of the needles and some opened cones on a Norway pine:

This species is not shade-tolerant.  It wants open ground and a lot of sunlight to grow successfully.  Despite wanting sunshine, it also likes cool summers and cold winters, which is why it thrives in Canada but not in the southern States.  If climate change causes temperatures to rise in the future, we may see that Norway pine becomes almost entirely a Canadian tree.  Like most other pines, this species prefers well-drained sandy or loamy soils, rather than clay.

Unfortunately, the Norway pine is susceptible to a fairly large range of insect pests, including pine beetles, pine gall weevil, pine needle miner, tussock moth, and sawflies.  However, these problems are much worse in warm climates, and don't have as significant an impact on the population in Canada.

Here are three fun facts about the Norway pine:
1.  This species was planted in large quantities during very early tree planting programs in the United States.  During the Great Depression, the Civilian Conservation Corp planted millions of these trees.
2.  The Norway pine is the State Tree of Minnesota.  In fact, Minnesota is probably the only area where people usually refer to this species as Norway pine instead of red pine.
3.  This species was historically a favoured tree for the construction of log cabins, due to its very straight and clean trunks.

At Replant.ca Environmental, Norway pine is just one of a large number of species that we use on some of our projects!
