"It’s all up from here": Forest openings and seedling growth in western white pine restoration

For centuries, western white pine (Pinus monticola) dominated moist forests of the northern Rocky Mountains. The fast-growing species, which can reach heights of 150 feet, was once an economic driver in the region. However, not much of the former forest remains. A combination of blister rust, beetles, and logging severely reduced the range of white pine during the 20th century.

Armillaria altimontana is not associated with reduced growth or survival of western white pine (Pinus monticola) planted in northern Idaho

Armillaria altimontana and A. solidipes frequently co-occur (McDonald et al. 2000) and are commonly found in association with western white pine (Pinus monticola). Armillaria solidipes (as A. ostoyae) is well-known as a virulent primary pathogen on diverse conifers within inland western regions of the contiguous USA (Lockman and Kearns 2016), whereas A. altimontana is considered to be a weak or secondary pathogen (Brazee et al. 2012).

Armillaria altimontana is associated with healthy western white pine (Pinus monticola): Potential in situ biological control of the Armillaria root disease pathogen, A. solidipes

Research Highlights: Two genets of Armillaria altimontana Brazee, B. Ortiz, Banik, and D.L. Lindner and five genets of Armillaria solidipes Peck (as A. ostoyae [Romagnesi] Herink) were identified and spatially mapped within a 16-year-old western white pine (Pinus monticola Doug.) plantation, which demonstrated distinct spatial distribution and interspecific associations. Background and Objectives: A. solidipes and A.

Deception Creek Experimental Forest

Deception Creek Experimental Forest is in one of the most productive forests in the Rocky Mountains. When the forest was established in 1933, large, old-age western white pine (Pinus monticola) were important for producing lumber products. The forest, located in the Coeur d'Alene Mountains, is in the heart of the western white pine forest type.

Restoring dry and moist forests of the inland northwestern United States [Chapter 23]

The complex topography of the Inland Northwestern United States (58.4 million ha) interacts with soils and a highly variable climate to provide a mosaic of dry and moist mixed conifer forest settings.

Western white pine development in relation to biophysical characteristics across different spatial scales in the Coeur d'Alene River basin in northern Idaho, U.S.A

Many studies have assessed tree development beneath canopies in forest ecosystems, but results are seldom placed within the context of broad-scale biophysical factors. Mapped landscape characteristics for three watersheds, located within the Coeur d’Alene River basin in northern Idaho, were integrated to create a spatial hierarchy reflecting biophysical factors that influence western white pine (Pinus monticola Dougl. ex D.

Biophysical characteristics influencing growth and abundance of western white pine (Pinus monticola) across spatial scales in the Coeur d'Alene River Basin, Idaho

During the past 50 years the moist forests of northern Idaho changed from being dominated by western white pine (Pinus monticola), an early sera! species, to ones dominated by late serial species, grand fir (Abies grandis) and western hemlock (Tsuga heterophylla). Variable fire regimes, successional processes and endemic insects and pathogens worked in concert to produce the stable and resilient forests of the past.

Exponential fertilization of Pinus monticola seedlings: nutrient uptake efficiency, leaching fractions, and early outplanting performance

We evaluated nutrient uptake efficiency and subsequent leaching fractions for western white pine (Pinus monticola Dougl. ex D. Don) seedlings grown with exponentially increasing or conventional (constant) fertilization in a greenhouse.

Silvics of western white pine

Western white pine grows along west coast mountain ranges from Vancouver Island and the Homathko River on the adjacent mainland in British Columbia southward to the San Bernardino Mountains of southern California (13, 65, 75, 83).

Juvenile performance of hybrids between western and eastern white pine

The growth and performance of Pinus monticola, P. strobus, and their hybrids were investigated at several sites in northern Idaho and western Montana. At three sites in northern Idaho, two hybrid progenies were approximately twice as tall and markedly excelled corresponding P. monticola progenies (having the same female parents) in height growth at age 8 years . At one site in western Montana none of the few P. monticola, P.
