First noticed in the mountains above Farmington Canyon and near Powder Mountain Resort, it has Dieback and decline of subalpine fir due to attack by balsam woolly adelgid. Photo credit: Darren McAvoy. 2017, forest health professionals visited Farmington Canyon on the ground and found branch node swelling (a node is where branch structures come together) and old deposits of woolly material on mature subalpine fir trees. Suspected to have originated in the Caucasus Mountains between Europe and Asia, BWA was first detected in North America in Maine, in 1908, and in California about 20 years later. It was detected in Idaho near Coeur d’Alene in 1983 and has since spread across northern Idaho. It is believed that separate invasions of subspecies or races of BWA may differentially impact tree host species. Dieback of subalpine fir, pacific silver (Abies amabilis) and grand fir (A. grandis) in Idaho is widespread. In the western Payette National Forest, north of Boise, an estimated 70% of subalpine fir trees are dead and falling down.

Abstract: The polypore Bridgeoporus nobilissimus produces large perennial basidiocarps on large diameter Abies stumps, snags and trees in coniferous forests of the Pacific Northwest. Despite the size and persistence of the basidiocarps, they are rarely observed, making the conservation of this species a concern. We determined that a genetic marker for this fungus could be detected in DNA extracted from wood cores taken from trees hosting basidiocarps. We then tested 105 trees and stumps that did not host B. nobilissimus basidiocarps in plots surrounding B. nobilissimus conks, and 291 trees and stumps in randomly located plots in four stands that contained at least one B. nobilissimus basidiocarp. We found that trees of all sizes throughout all of the stands hosted B.

TREES AS CROPS in ALASKA PROFILE with an EMPHASIS on SPRUCE Revised 2009
TREES AS CROPS IN ALASKA PROFILE WITH AN EMPHASIS ON SPRUCE Revised 2009 Robert A. Wheeler Thomas R. Jahns Janice I. Chumley PRODUCTION FACTS Growing trees in Alaska can be difficult. This document addresses basic questions regarding growing tree seedlings as an agricultural crop. Whether growing a few seedlings or thousands, many of the basic production questions are the same. From the standpoint of tree seedling production there are three basic regions in Alaska: Southeast, South Central, and the Interior. Producing high quality tree seedlings is 4-H Tree Sale in Soldotna, AK May 2003 achievable in all three regions however care must (photo/Bob Wheeler). be taken to match tree species requirements with local environmental conditions. Through the efforts of the University of Alaska Fairbanks and the Agriculture and Forestry Experiment Station, many tree species have been evaluated over the past 100 years for their performance. Results from these species trials have led to the listing of tree species, growth characteristics, and site requirements found in Table 1. DEMAND Interest in tree production can vary from growing trees for your yard or property to full scale outdoor or greenhouse, bareroot, or container nurseries. Tree planting and tree sales continue to be of considerable interest to the public although there are no large-scale commercial tree nurseries currently operating in Alaska. A state tree nursery was once operated in the Matanuska Valley area, but it has been closed. Reasons for the closure were based upon the high cost of producing seedlings in Alaska versus what it would cost to import them from nurseries outside the state and also, the overall operational difficulties and risks associated with an Alaska nursery program.

Hybridization of the California Firs
Forest Science, Vol. 34, No. I, pp. 139-151. Copyright 1988 by the Society of American Foresters Hybridization of the California Firs William B. Critchfield Abstract. Four groups of firs (sections, in the most recent classification of Abies) are represented in California. Crossing within these sections is possible and even easy, and in two of the sections intergrading populations between highly crossable taxa are wide spread in California. An exception is A. amabilis, a Northwestern fir that has not been crossed with other species in the same section {Grandes: A. concolor, A. grandis) or in other sections (e.g., Nobiles: A magnified). Crossing species in different sections is usually difficult or impossible. The genetic isolation of A. bracteata, an endemic species classified as a monotypic subgenus or section, may be nearly complete: two probable hybrids with A. concolor died at a few years of age. A few putative hybrids from inter- sectional crosses between species in Grandes and Nobiles died within months of germi nation. Intersectional crosses with firs outside California (two Mexican and four Eur asian species) all failed except A. concolor x A. religiosa, which produced numerous healthy hybrids. The common occurrence of genetic barriers in Abies is at odds with the long-held view that it is easy to hybridize fir species. For. Sci. 34(1): 139-151. Additional key words. Abies, interspecific hybrids, crossability, classification. The ability of species to hybridize has not been explored as systemati cally in the genus Abies (true firs) as it has in other genera of Pinaceae such as Pinus and Pice a.

True fir-hemlock spacing trials: design and first results. Gen. Tech. Rep. PNW-GTR-492. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 35 p. A series of 18 precommercial thinning trials was established in true fir-hemlock stands in the Olympic Mountains and along the west side of the Cascade Range in Washington and Oregon from 1987 through 1994. This paper documents estab- lishment of these installations and presents some preliminary observations and results. Substantial differences in growth rates in height and diameter were ob- served among Pacific silver fir, western hemlock, and noble fir. Diameter growth of all species increased as spacing increased, but height growth of silver fir and noble fir decreased at wider spacings in some areas. These installations will pro- vide a unique source of information on early development of managed stands of these species, for which little information now is available.

Subalpine Fir (Bl)- Abies Lasiocarpa
Subalpine fir (Bl)- Abies lasiocarpa Tree Species > Subalpine fir Page Index Distribution Range and Amplitiudes Tolerances and Damaging Agents Silvical Characteristics Genetics and Notes BC Distribution of Subalpine fir (Bl) Range of Subalpine fir Old-growth, subalpine fir stands cover a large area of the ESSF zone, particularly in wetter areas, such as northwest of Smithers Geographic Range and Ecological Amplitudes Description Subalpine fir is a medium - to large-sized (exceptionally >40 m tall), evergreen conifer, at maturity with a low-taper stem, narrow, dense, cylindrical crown, with a spire-like top, short, drooping branches, and grayish-brown bark, breaking into irregular scales with age. Its light, soft, odorless wood is used mainly for lumber. Geographic Range Geographic element: Western North American/mainly Cordilleran and less Pacific Distribution in Western North America: (central) in the Pacific region; north, central, and south in the Cordilleran region Ecological Amplitudes Climatic amplitude: (alpine tundra) - continental subalpine boreal - montane boreal - (cool temperate) Orographic amplitude: montane - subalpine - (alpine) Occurrence in biogeoclimatic zones: (lower AT), submaritime MH, SWB, ESSF, MS, (BWBS), SBS, (upper IDF), upper ICH, (wetter submaritime CWH) Subalpine fir grows mainly in humid, continental boreal climates, with a short growing season; less frequently in cool temperate climates, with a longer growing season. When these climates become drier and/or warmer, subalpine fir is absent or its occurrence is rare (e.g., in the SBPS and PP zones). Edaphic Amplitude Range of soil moisture regimes: (moderately dry) - slightly dry - fresh - moist - very moist - wet Range of soil nutrient regimes: very poor - poor - medium - rich - very rich Field studies indicate that subalpine fir is most vigorous on moist and rich sites, with calcium - and magnesium-rich soils such as those derived from basaltic or limestone parent materials.
