This unique tree is one of FOREST, WHEN I MOVED TO WESTERN MONTANA MANY only four deciduous conifers, in addition to baldcypress (Taxodium YEARS AGO, I WAS AWESTRUCK. A friend and I had hiked up distichum), tamarack (Larix laricina), and western larch (Larix to Carlton Ridge, high on the horizon southwest of Missoula near occidentalis), that are native to North America. Alpine larch is Lolo Peak, during early fall. Snow was already starting to blanket the also unusual in being the only erect deciduous tree that inhabits mountains, and I was not really anticipating that we would soon be the alpine timberline. In the Bitterroot Mountains, the species is hiking through a forest of fall color. As we steadily made our way abundant above 7,500 feet on north-facing slopes, and rarely occurs up into the larches that cover the top of the ridge, though, it was below 6,500 feet. like entering a golden tunnel. The combination of brilliant yellow needles on the larch trees, the white mantle of snow, and the blue Distribution of sky was breathtaking, unlike any other forest I had ever visited. alpine larch in the As these trees change color during the last half of September, Pacific Northwest. the appearance of the golden-yellow “cap” on Carlton Ridge marks the onset of fall, and is readily visible from Missoula. This colorful stand of alpine larch (Larix lyallii) is one of the most unique forests in the northern Rocky Mountains. The ridgeline in this high- elevation area above the Mormon Creek drainage escaped past glaciation, and as a result there is an unusual layer of deeper soil that is much unlike the very rocky sites that alpine larch typically DERICKSON MAP: EVAN 4 MONTANA NATURALIST ~ SPRING/SUMMER 2018 Both alpine and western larch are tree growth rates. In the case of ponderosa pine (Pinus ponderosa), endemic to a relatively small geographic tree growth rates have been increasing since the 1950s, especially area in the Pacific Northwest. Alpine in older trees on drier sites. The increase in carbon dioxide in larch is confined to the higher, cooler the atmosphere may be having a “fertilizer effect” on the trees, environment of the upper subalpine as such change can cause the trees to use water more efficiently. and lower alpine zones in the inland On Carlton Ridge, the growth rings in alpine larches have been northwest. It occupies limited areas studied to understand the historic extent of fire in the northern of southern British Columbia and Rocky Mountains. That study revealed an average tree age of southwestern Alberta, and extends approximately 350 years, a remarkable number considering that the southward into Washington, northern average diameter of the trees is only about 17 inches!

Western [A recent] study revealed an average near Trapper Peak in the southern larch occupies lower Bitterroot Mountains occupy sites on and middle elevations tree age of approximately 350 years, both north- and south-facing slopes, over roughly the same a remarkable number considering that with the former having higher soil geographic area, although the average diameter of the trees is moisture and cooler temperatures on its range extends into average.
