The western and subalpine larch turn a bright, almost dusty yellow, which stands out in stark contrast to the pale granite of the Enchantments.

Larix lyallii Subalpine larch.

Subalpine larch is hardy and can survive very low temperatures in thin rocky soils, which is why the tree is often found near treeline.

Larix lyallii, the subalpine larch, or simply alpine larch, is a deciduous, coniferous tree native to northwestern North America.

Spring snowpack is negatively correlated with growth for all three species, but the relationship is strongest for subalpine fir and weakest for subalpine larch.

A thicker ring indicates more snow for some species, like Douglas firs or ponderosa pines; for others, like subalpine larch, more snow leads to thinner rings.

The subalpine fir forests in the North Cascades include Douglas fir, Engelmann spruce, subalpine larch, and whitebark pine.

• The area is mainly within the sub-alpine and alpine ecoregions and contains spruce/fir forest, subalpine larch woodlands, patches of alpine meadow, and typical mountain wildlife.

The greatest differences are between subalpine fir and subalpine larch, while the greatest similarities are between subalpine fir and Engelmann spruce.

For example, Snow Gum in Australia, or Subalpine Larch, Mountain Hemlock and Subalpine Fir in western North America.

Nutt.), Engelmann spruce (Piceaengelmannii Parry), and subalpine larch (Larixlyallii Parl.) in the North Cascade Mountains of Washington state.

This species can be found in woodlands, subalpine larch forests and mountain forests of the Alps, the Southern Ural mountains, Southern Siberia and Korea and Japan.

In the drier, interior regions, the higher elevations are marked by Engelmann Spruce, Subalpine Fir, Subalpine Larch, and Lodgepole Pine, the trees clumped among meadows and grassland.

Common trees showing krumholtz formation include European spruce, mountain pine, balsam fir, red spruce, black spruce, subalpine fir, subalpine larch, Engelmann spruce, limber pine, and lodgepole pine.

Species that occur in this zone depend on the location of the zone on the Earth, for example, snow gum in Australia, or subalpine larch, mountain hemlock and subalpine fir in western North America.

This forest has the most diverse trees of the forested ecoregions in Washington state which includes grand fir, Douglas fir, Engelmann spruce, subalpine fir, ponderosa pine, lodgepole pine, western white pine, whitebark pine, western larch, and subalpine larch.

But what is it about the alpine larch that sparks such passion?

Alpine larch provide brilliant yellow patches of colour each autumn.

Up in the higher reaches of the Missions one finds the alpine larch.

Like mountain goats, alpine larches cling to the rocks at the very top of the tree line.

It is most commonly seen below the timberline in areas with whitebark pine and alpine larch.

Alpine larch, a deciduous conifer, has many very narrow and missing rings, making chronology development difficult.

Alpine larch adds a splash of gold to the uniform green-black of the forest in autumn.

Seeds are less useful in recognizing hybrids, but are distinctive between western and alpine larch.

The cross to alpine larch females was highly successful; 63% of the seeds developed mature embryos and 79% germinated.

Less than 1% of the alpine larch hypocotyls were reddish in color; most of them were green.

Western larch cones have a smaller length:width ratio than alpine larch.

If you go later in the year, you will be stunned by the brilliance of the alpine larches becoming golden in the autumn months.

You almost feel as if you should be in Asia, within striking distance of the Himalayas, where the alpine larch also grows.

Near the timber line, alpine larch and white bark pine are interspersed with fir and spruce.

The typical alpine larch, which is also called Western tamarack and mountain larch, is less than 50 feet tall.

Unlike the alpine larch, the Western larch is found at much lower elevations, growing fast, straight and as tall as 200 feet.

Stems of hybrids were significantly thicker than those of either western larch or alpine larch.

The high correlation between the six first principal component and standard chronologies suggested that either method may be used for standardizing tree-ring data from alpine larch.

Alpine larch (L. lyallii) occurs at high elevations in southern BC and Alberta.

Open-pollinated western larch and alpine larch averaged 26 and 32% filled seed with 48 and 44% germination, respectively.

The alpine larch and alpine fir chronologies are the first published chronologies developed for these species in the Canadian Cordillera.

However, 4 months following germination, western larch seedlings were ca. four times taller than the hybrids and 10 times taller than alpine larch.

Larix lyallii, the subalpine larch, or simply alpine larch, is a deciduous, coniferous tree native to northwestern North America.

• Conducted research into the history and roles of fire, post fire ecology, forest health surveys and regeneration for Douglas fir, alpine larch and whitebark pine.

Linear discriminant functions for these terpenes and volatiles were developed for species classes (alpine larch, western larch, and hybrids) previously identified by morphological features.

Subalpine Larch (Larix lyallii)
