European Larch

At an event distributing white oak saplings for the bicentennial of Oakland County I was asked, “Are the large Tamaracks in Oakview Cemetery native?” Oakview is a century-old cemetery in Royal Oak. The back of the property was undeveloped woods when I was a boy. Tamaracks were harvested in Royal Oak township for the ship building industry in the late 1800s, but I did not know of any Tamaracks remaining in the city. Notes from the 1817 land survey seem to indicate that the cemetery land was always dry, but a swampy area was just to the southeast. Geological maps show a sandy beach ridge running across the property.

I followed the directions and found the trees quickly by driving the center road to the west. Once I saw the shape of the trees, I knew they were European Larch (Larix decidua). This is also called European Tamarack. It is similar to our native Eastern Tamarack (Larix laricina). See my blog post

Just like our native Tamarack, European Larch needles turn a bright yellow in the fall before they are shed for the winter. European Larch has bigger cones with 35-50 scales that have short hairs. Our native tamarack has less than 20 scales and they are hairless. European Larch needles normally are longer than 2.5 cm [1 inch]. They are shorter on our native Eastern Tamarack. The twigs on the European Larch are yellowish. Our Native Tamarack has brownish twigs that turn gray with age.

I walked around the cemetery looking at other trees. It has some large Black Oaks and nice White Pines. Just below the crest of the beach ridge I found an Eastern Tamarack with a trunk 2-feet in diameter. I think it was planted on the ridge because Eastern Tamarack does not grow on dry sandy sites.

It was interesting to walk the cemetery, looking at old trees. There are not too many sites where you can compare the two Tamarack species.

Michigan’s deciduous “Evergreen”

Larix laricina Autumn

Tamarack in Autumn

Tamarack or American Larch (Larix laricina) is the only conifer in Michigan that sheds its leaves every fall. Last weekend in the Grayling area they were golden, glowing in the sunshine. One of the last trees to turn color its golden leaves are often in contrast with the snow.

Walking through a grove of Tamaracks in the winter is surreal. Their dark grey, brittle, bare, twisted branches appear dead. The leaf scar spurs look like knuckles and the trees appear to have fingers. Illustrations of the tree can be found in horror books.

In the spring the soft green clusters of leaves grow on short spurs and the reddish pollen cones spring forth. Gymnosperms (which include the conifers) are no longer said to have flowers but have pollen (male) and seed-bearing (female) cones. The seed-bearing cones hang on the trees for several years but lose their seeds during the winter or early spring.

Tamaracks grow in wet areas, often in quaking bogs. Their long fibrous roots spread out and anchor the tree in place. These flexible roots were used by Native Americans to sew birch bark onto canoes. The wood is resistant to rot and was commonly used to layer corduroy roads. It currently has little commercial value.

Tamaracks are easy to spot this time of year. Look for them in low, undisturbed areas throughout Michigan.
