Tamarack (Larix Laricina) by Joyce Tuharsky
Natives to Know: Tamarack (Larix Laricina) By Joyce Tuharsky One of our northernmost trees, the hardy Tamarack is a slender-trunked, conical tree that grows 50-75 feet tall. The needles are a bright blue-green and surprisingly soft. They grow in tight spirals around short knobby spurs along the twigs. Tamaracks are among the few conifers that lose their needles in autumn. Just before the needles drop, the needles turn a beautiful golden-yellow. Tamarack cones are egg-shaped and among the smallest: less than an inch long. The bark is tight and flaky. Under this flaking bark, the wood appears reddish, giving the tree an interesting appearance even without needles. Very cold tolerant, Tamaracks are able to survive temperatures down to −85 °F. They are commonly found at the arctic tree line where it grows as a shrub. In more southerly locations, Tamaracks are normally found in wet soils in swamps, bogs and along lake edges. They are among the first trees to invade filled-lake bogs and are fairly well adapted to reproduce after a fire. However, because of its thin bark and shallow root system, the tree itself does not stand up well to fire. Also, the seedlings do not establish well in shade. Consequently, other more shade tolerant species eventually succeed Tamaracks. Tamaracks are native to much of Canada and south into the northeastern US from Minnesota to West Virginia. Because obits extensive range, the tree is known by many names: American Larch, Eastern Larch, Red Larch, and Hackmatack. The name “Tamarack” is Algonquian and means "wood used for snowshoes."Indeed, because Tamarack wood is very sturdy, yet flexible in thin strips, Native Americans used the wood and roots for many things: snowshoes, toboggans, sewing edges of canoes, and weaving twined bags.

Susceptibility of Larch, Hemlock, Sitka Spruce, and Douglas-Fir to Phytophthora Ramorum1
Proceedings of the Sudden Oak Death Fifth Science Symposium Susceptibility of Larch, Hemlock, Sitka Spruce, and 1 Douglas-fir to Phytophthora ramorum Gary Chastagner,2 Kathy Riley,2 and Marianne Elliott2 Introduction The recent determination that Phytophthora ramorum is causing bleeding stem cankers on Japanese larch (Larix kaempferi (Lam.) Carrière) in the United Kingdom (Forestry Commission 2012, Webber et al. 2010), and that inoculum from this host appears to have resulted in disease and canker development on other conifers, including western hemlock (Tsuga heterophylla (Raf.) Sarg.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), grand fir (Abies grandis (Douglas ex D. Don) Lindl.), and Sitka spruce (Picea sitchensis (Bong.) Carrière), potentially has profound implications for the timber industry and forests in the United States Pacific Northwest (PNW). A clearer understanding of the susceptibility of these conifers to P. ramorum is needed to assess the risk of this occurring in the PNW. Methods An experiment was conducted to examine the susceptibility of new growth on European (L. decidua Mill.), Japanese, eastern (L. laricina (Du Roi) K. Koch), and western larch (L. occidentalis Nutt.); western and eastern hemlock (T. canadensis (L.) Carrière); Sitka spruce; and a coastal seed source of Douglas-fir to three genotypes (NA1, NA2, and EU1) of P. ramorum in 2011. In 2012, a similar experiment was conducted using only the four larch species. Container-grown seedlings or saplings were used in all experiments. Five trees or branches of each species were inoculated with a single isolate of the three genotypes by spraying the foliage with a suspension of zoospores (105/ml).

Review of British Columbia's Contemporary and Projected
Review of British Columbia’s contemporary and projected western larch seed planning zones in light of climate change. Barry Jaquish Research and Knowledge Management Branch, B.C. Ministry of Forests and Range Kalamalka Forestry Centre, Vernon, B.C. February 26, 2010 Background The catastrophic effects of mountain pine beetle on the forests of central British Columbia combined with the projected effects of climate change have stimulated intense debate over forest management throughout the region. One commonly suggested approach to mitigating these effects is to increase the region’s ecosystem complexity through the planting of either exotic tree species or native species whose distribution lies outside the central Interior. While the benefits of introducing exotic species remains controversial and speculative, the assisted, or facilitated, migration of native species presents a valuable tool for enhancing ecological complexity and ensuring the species’ pace of migration matches the expected rate of climate change. Western larch (Larix occidentalis Nutt), a species native to the upper Columbia River basin in southeastern B.C. (Fig. 1), is often suggested as a desirable candidate for introduction because of its rapid early growth, desirable wood properties, and generalist mode of adaptation. Indeed, western larch is already commonly planted north of its native range in southeastern B.C. (Plate 1) and over the last three decades numerous small operational and research plantings have demonstrated western larch’s reforestation potential on many sites throughout the central Interior (Plates 2, 3, 4, and 5). Ecologically, it appears that western larch’s fundamental niche exceeds its realized niche. Climate envelope modelling also suggests that the future climate space amenable to western larch lies far north of its contemporary distribution.

Western Larch, Which Is the Largest of the American Larches, Occurs Throughout the Forests of West- Ern Montana, Northern Idaho, and East- Ern Washington and Oregon
Forest An American Wood Service Western United States Department of Agriculture Larch FS-243 The spectacular western larch, which is the largest of the American larches, occurs throughout the forests of west- ern Montana, northern Idaho, and east- ern Washington and Oregon. Western larch wood ranks among the strongest of the softwoods. It is especially suited for construction purposes and is exten- sively used in the manufacture of lumber and plywood. The species has also been used for poles. Water-soluble gums, readily extracted from the wood chips, are used in the printing and pharmaceutical industries. F–522053 An American Wood Western Larch (Lark occidentalis Nutt.) David P. Lowery1 Distribution Western larch grows in the upper Co- lumbia River Basin of southeastern British Columbia, northeastern Wash- ington, northwest Montana, and north- ern and west-central Idaho. It also grows on the east slopes of the Cascade Mountains in Washington and north- central Oregon and in the Blue and Wallowa Mountains of southeast Wash- ington and northeast Oregon (fig. 1). Western larch grows best in the cool climates of mountain slopes and valleys on deep porous soils that may be grav- elly, sandy, or loamy in texture. The largest trees grow in western Montana and northern Idaho. Western larch characteristically occu- pies northerly exposures, valley bot- toms, benches, and rolling topography. It occurs at elevations of from 2,000 to 5,500 feet in the northern part of its range and up to 7,000 feet in the south- ern part of its range. The species some- times grows in nearly pure stands, but is most often found in association with other northern Rocky Mountain con- ifers.

Conclusion Literature Cited 1 Abstract Climate change research has shown irrefutably that global temperatures are rising, and almost all climate-model projections agree that in the coming decades the western US is likely to experience warmer springs and summers. Hotter and drier conditions are a concern for the future of western forests because climate is an important factor in determining plant distributions. The general effects of climate change on forests include a significant increase to the variability in disturbance regimes, shifts in species ranges, or a shift in germination and establishment requirements. Adding to the complexity of challenges faced by western forests are the poor land management practices of the 20th century, such as fire suppression and high- grade logging, which have led to an adverse change in forest structure including a decline in shade intolerant species such as western larch (Larix occidentalis).

Following a wildfire, regeneration to forest can take decades to centuries and is no longer assured in many western U.S. environments given escalating wildfire severity and warming trends. After large fire years, managers prioritize where to allocate scarce planting resources, often with limited informa- tion on the factors that drive successful forest establishment. Where occurring, long-term effects of postfire salvage operations can increase uncertainty of establishment. Here, we collected field data on postfire regeneration patterns within 13- to 28-yr-old burned patches in eastern Washington State.
