Forb common garden study to inform seed transfer guidance for restoration

Projects Posted on: July 31, 2019
Seed-grown plants from multiple populations of three focal forb species will planted in gardens across the Great Basin in order to capture important information that affects where seeds are sourced for restoring native plants at specific locations.

Climate-related genetic variation in a threatened tree species, Pinus albicaulis

Publications Posted on: September 25, 2017
PREMISE OF THE STUDY: With ongoing climate change, understanding of intraspecific adaptive variation is critical for conservation and restoration of plant species. Such information is especially scarce for threatened and endangered tree species, such as Pinus albicaulis Engelm. Therefore, our principal aims were to assess adaptive variation and characterize its relationship with climate of seed origin. METHODS: We grew seedlings from 49 P.

Tracking climate change and assisted migration for native plants

Science Spotlights Posted on: April 16, 2015
Researchers compiled a literary database about native plant transfer guidelines, climate change, and assisted migration. This database can help inform scientists, land managers, and university students about climate change and assisted migration through presentations and publications that cover the historical, biological, social, legal, and ethical aspects of assisted migration.

Genetic variation in adaptive traits and seed transfer zones for Pseudoroegneria spicata (bluebunch wheatgrass) in the northwestern United States

Publications Posted on: September 11, 2013
A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases commonly used in restoration.

Preparing for climate change: Forestry and assisted migration

Publications Posted on: September 06, 2013
Although plants have moved across the landscape in response to changing climate for millennia, projections of contemporary climate change suggest that forest tree species and populations will need to migrate faster than their natural ability. Therefore, climate change adaptation strategies, such as assisted migration, have gained attention since 2007.

Adaptive variation in Pinus ponderosa from Intermountain regions. II. Middle Columbia River system

Publications Posted on: August 17, 2011
Seedling populations were grown and compared in common environments. Statistical analyses detected genetic differences between populations for numerous traits reflecting growth potential and periodicity of shoot elongation. Multiple regression models described an adaptive landscape in which populations from low elevations have a high growth potential while those from high elevations have a low growth potential.

The role of genetics in improving forest health

Publications Posted on: June 20, 2006
An often ignored tool to improve forest health is the application of genetics-Tree improvement programs in the Inland West utilize genetic principles to develop-seed transfer guidelines to avoid the problems associated with off-site plantings and to improve characteristics in conifers related to forest health. PC-based expert systems have been developed to aid in seed transfer in ponderosa pine and Douglas-fir.
