Population history provides foundational knowledge for utilizing and developing native plant restoration materials

Publications Posted on: December 06, 2018
A species’ population structure and history are critical pieces of information that can help guide the use of available native plant materials in restoration treatments and decide what new native plant materials should be developed to meet future restoration needs.

Testing the efficacy of seed zones for re-establishment and adaptation of bluebunch wheatgrass (Pseudoroegneria spicata)

Projects Posted on: February 09, 2016
Previous research funded by the Great Basin Native Plant Project found that bluebunch wheatgrass (Pseudoroegneria spicata) populations differed in traits important for adaptation to precipitation and temperature (St. Clair et al. 2013). Forest Service scientists hypothesize that in the long-term, populations from local seed zones will better establish, survive, and reproduce than those from non-local seed zones. This study examines the efficacy of seed zones for bluebunch wheatgrass to ensure successful establishment and allow for long-term adaptation by maintaining genetic diversity.

Plant Guide: Bluebunch wheatgrass: Pseudoroegneria spicata

Publications Posted on: September 19, 2013
Grass Family (Poaceae). Bluebunch wheatgrass is a perennial native bunchgrass. Bluebunch wheatgrass is highly variable and grows to 1.5 to 4 feet (0.4 to 1.2 m) tall with seed spikes 3 to 8 inches (76 to 200 mm) long. The auricles are pointed and semi-clasping to nearly lacking. Leaves are lax, cauline, flat to in-rolled, 0.6 to 0.25 inches (4 to 6 mm) wide, and green to blue in color. The sheath is generally glabrous.

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.

Notice to release Anatone germplasm bluebunch wheatgrass (selected class natural population)

Publications Posted on: June 05, 2012
Anatone is a natural, non-manipulated bluebunch wheatgrass population accession originating from Asotin County in Southeastern Washington. It is a long-lived perennial bunchgrass better adapted to low elevation, semi-arid sites with long, hot growing seasons than other bluebunch wheatgrass accessions or available releases. Its seedling vigor and establishment also exceed those of other accessions and released cultivars.

Population-level compensation impedes biological control of an invasive forb and indirect release of a native grass

Publications Posted on: May 30, 2012
The intentional introduction of specialist insect herbivores for biological control of exotic weeds provides ideal but understudied systems for evaluating important ecological concepts related to top-down control, plant compensatory responses, indirect effects, and the influence of environmental context on these processes.

Influence of herbivory and competition on invasive weed fitness: Observed effects of Cyphocleonus achates (Coleoptera: Curculionidae) and grass-seeding treatments on spotted knapweed performance

Publications Posted on: October 03, 2011
The root-feeding weevil Cyphocleonus achates (Fahraeus) is a promising biological control agent for managing the exotic, invasive weed spotted knapweed. The objective of this study was to compare the relative and potentially interactive effects of competition and specialized herbivory on spotted knapweed fitness.

Competitive effects of bluebunch wheatgrass, crested wheatgrass, and cheatgrass on antelope bitterbrush seedling emergence and survival
