Forest gaps and western white pine regeneration

Events Posted on: October 06, 2020
In this webinar, RMRS research forester Terrie Jain joined Jason Jerman (Coeur d’Alene River Ranger District), James Pass (Three Rivers Ranger District), and Shelagh Fox (R-1 Regional Silviculturist) to discuss forest openings and seedling growth in western white pine restoration.

Armillaria altimontana, a potential natural biological control against Armillaria root disease

Publications Posted on: September 30, 2020
Root diseases are a primary cause of reduced forest productivity, decreased carbon sequestration, and impaired ecosystem function (e.g., Lockman & Kearns 2016). Armillaria altimontana and A. solidipes (as A. ostoyae) are soil fungi that frequently co-occur (McDonald et al. 2000) and are found in association with western white pine (Pinus monticola).

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

Publications Posted on: September 14, 2020
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.

Canopy opening and site preparation effects on conifer and understory establishment and growth after an uneven-aged free selection regeneration harvest in the northern Rocky Mountains, USA

Forest management is trending toward creating multi-aged forest structures and diverse vegetative compositions. The challenge is successfully designing and implementing treatments that create these diverse forests. Regeneration establishment is the most important step when applying a silvicultural system because it determines future treatments and optimizes management options.

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).

White pine in the American West: A vanishing species - can we save it?

Publications Posted on: August 01, 2018
Forest scientists ask that everyone, from the home gardener to the forest manager, help revive western white pine by planting it everywhere, even in nonforest environments such as our neighborhood streets, parks, and backyards. White pine, long ago considered the "King Pine," once dominated the moist inland forests of the Northwest, eventually spawning whole industries and historical movements.

Deception Creek Experimental Forest

Publications Posted on: May 11, 2018
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.

The role of silviculture in ecosystem management: a practice in transition

Publications Posted on: May 11, 2018
The cedar (Thuja plicata) -hemlock (Tsuga heterophylla) -white pine (Pinus monticola) forests are some of the most productive in North America. Silvicultural practices used in these forests originated in Europe and usually concentrated on producing high-value commercial products.

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

Publications Posted on: March 27, 2018
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

Publications Posted on: March 27, 2018
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.
