Southwestern white pine (Pinus strobiformis) species distribution models project a large range shift and contraction due to regional climatic changes

Publications Posted on: November 19, 2018
Southwestern white pine (Pinus strobiformis; SWWP) is a conifer species that occurs at mid to high elevations in the mountains of Arizona, New Mexico, and northern Mexico. A key component of mixed conifer forests in the region, SWWP is an important species for wildlife and biodiversity.

Regeneration for resilience framework to support regeneration decisions for species with populations at risk of extirpation by white pine blister rust

Publications Posted on: October 05, 2018
Natural forests are increasingly invaded by nonnative pests and pathogens that threaten host species with population extirpation and cascading ecological impacts.

A preliminary hazard model of white pine blister rust for the Sacramento Ranger District, Lincoln National Forest

Publications Posted on: May 12, 2016
Blister rust, caused by the introduced fungus Cronartium ribicola, is a serious disease of white pines in North America. Since about 1970, an outbreak has been increasing in the Sacramento Mountains of southern New Mexico and threatens southwestern white pine. To help determine the expected extent and impact of blister rust, we propose a preliminary hazard model for the Sacramento Ranger District.

High elevation white pines educational website

Publications Posted on: July 05, 2011
The high elevation five-needle white pines are facing numerous challenges ranging from climate change to invasion by a non-native pathogen to escalation of pest outbreaks. This website (http://www.fs.fed.us/rm/highelevationwhitepines/) serves as a primer for managers and the public on the high elevation North American five-needle pines.

Restoration planting options for limber pines in the southern Rocky Mountains

Publications Posted on: July 05, 2011
Limber Pine (Pinus flexilis) populations in the southern Rocky Mountains are severely threatened by the combined impacts of mountain pine beetles and white pine blister rust. Limber pine's critical role in these high elevation ecosystems heightens the importance of mitigating these impacts.

Limber pine seed and seedling planting experiment in Waterton Lakes National Park, Canada

Publications Posted on: July 05, 2011
Limber pine plays an important role in the harsh environments in which it lives, providing numerous ecological services, especially because its large, wingless seeds serve as a high energy food source for many animals. Limber pine populations are declining due to a combination of white pine blister rust, mountain pine beetle, drought, and fire suppression.

Guidelines for whitebark pine planting prescriptions

Publications Posted on: July 05, 2011
Whitebark pine (Pinus albicaulis) is a keystone species in high-elevation ecosystems of the western United States. Unfortunately many fragile subalpine ecosystems are losing whitebark pine as a functional community component due to the combined effects of an introduced disease, insects and succession. Planting whitebark pine is one part of a multifaceted restoration strategy (Keane and Arno 2001).

Whitebark pine direct seeding trials in the Pacific Northwest

Publications Posted on: July 05, 2011
Whitebark pine (Pinus albicaulis) is a critical species in many high elevation ecosystems and is currently in serious decline due to white pine blister rust (Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae), and competition from other species (Schwandt 2006; Tomback and Achuff 2010; Tomback and others 2001).

Highlights of the Forest Health Protection Whitebark Pine Restoration Program

Publications Posted on: July 05, 2011
In 2005, Forest Health Protection (FHP) initiated a rangewide health assessment for whitebark pine (Pinus albicaulis). This assessment summarized the forest health condition of whitebark pine throughout its range and also documented information needs, potential restoration strategies, and challenges to restoration that need to be addressed (Schwandt 2006).

No free lunch: Observations on seed predation, cone collection, and controlled germination of whitebark pine from the Canadian Rockies

Publications Posted on: July 05, 2011
Whitebark pine is a keystone species of high elevation forests in western North America that is experiencing rapid decline due to fire exclusion policies, mountain pine beetle, and the introduced pathogen, white pine blister rust. Restoration activities include collecting cones and growing seedlings from individuals that show mechanisms for resistance to blister rust infections.
