Limber pine (Pinus flexilis James) genetic map constructed by exome-seq provides insight into the evolution of disease resistance and a genomic resource for genomics-based breeding

Publications Posted on: May 16, 2019
Limber pine (Pinus flexilis) is a keystone species of high-elevation forest ecosystems of western North America, but some parts of the geographic range have high infection and mortality from the non-native white pine blister rust caused by Cronartium ribicola. Genetic maps can provide essential knowledge for understanding genetic disease resistance as well as local adaptation to changing climates.

Proactive limber pine conservation strategy for the Greater Rocky Mountain National Park Area

Publications Posted on: February 22, 2019
This proactive conservation strategy addresses the unique situation of limber pine in the Greater Rocky Mountain National Park Area (GRMNPA). The target area includes Rocky Mountain National Park and surrounding areas of northern Colorado and southern Wyoming.

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.

International Limber Pine Provenance Study (ILPPS): Rocky Mountain adaptive variation experiment

Projects Posted on: August 14, 2017
Limber pine is threatened by climate change, white pine blister, dwarf mistletoe, and mountain pine beetle. Scientists have planted limber pine in two contrasting environments to assess adaptive trait variation and plasticity, as well as climate interactions. Research such as the International Limber Pine Provenance Study (ILPPS) will support proactive managment to keep limber pine populations sustainable and prevent limber pine from following the same trajectory as whitebark pine.

Range-wide vulnerability of limber pine: White pine blister rust resistance and climate interactions

Projects Posted on: October 21, 2016
Forest surveys alone cannot predict species vulnerability as they cannot determine if the remaining healthy trees are at risk for disease or if they have heritable genetic resistance to support future populations. This project takes range-wide common garden (198 families) and artificial inoculation with Cronartium ribicola (causal agent of white pine blister rust) in order to better undertand host population vulnerability and sustainability.

Restoration planting options for limber pines in Colorado and Wyoming

Publications Posted on: September 30, 2016
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 pineʼs critical role in these high elevation ecosystems heightens the importance of mitigating these impacts.

Resistance to white pine blister rust in Pinus flexilis and P

Publications Posted on: September 30, 2016
The non-native fungus Cronartium ribicola, that causes white pine blister rust (WPBR), is impacting or threatening limber pine, Pinus flexilis, and Rocky Mountain bristlecone pine, Pinus aristata. In the Southern Rockies, where the rust invasion is still expanding, we have the opportunity to be proactive and prepare the landscape for invasion.

Restoration planting options for limber pines impacted by mountain pine beetles and/or white pine blister rust in the Southern Rocky Mountains

Publications Posted on: September 30, 2016
Limber Pine (Pinus flexilis) populations in the southern Rock Mountains are severely threatened by the combined impacts of mountain pine beetles and white pine blister rust. Limber pine’s critical role these high elevation ecosystems heightens the importance of mitigating impacts.

Life on the edge for limber pine: Seed dispersal within a peripheral population

Publications Posted on: September 30, 2016
Interactions within populations at the periphery of a species' range may depart from those in populations more centrally located. Throughout its core range, limber pine (Pinus flexilis, Pinaceae) depends on Clark's nutcrackers (Nucifraga columbiana, Corvidae) for seed dispersal. Nutcrackers, however, rarely visit the Pawnee National Grassland peripheral population of limber pine on the eastern Colorado plains.

First report of two cone and seed insects on Pinus flexilis

Publications Posted on: September 30, 2016
Limber pine (Pinus flexilis James) ranges in latitude from 33°N to 51°N and in elevation from 870 m above sea level (asl) in North Dakota to ~3400 m asl in Colorado (Burns and Honkala 1990). In the central Rocky Mountains, limber pine co-occurs with many tree species due to its broad elevational range (Peet 1981). Limber pine seeds are large, generally wingless, and dispersed by birds (Lanner and Vander Wall 1980).
