Invasive Species Science Update (No. 10)

Publications Posted on: April 26, 2018
In this issue, we cover new research on wide-ranging topics from the longterm effects of drought on competition between native and invasive plant species, to the effects of drought on pollinator visitation to invasive plants, to a novel use of insect pheromones to improve biocontrol of invasive saltcedar.

Factors effecting emergence of 20 Great Basin native forbs when sown at depths typical of rangeland drills

Projects Posted on: April 20, 2018
This study evaluated the effects of species, sowing depth and dormancy status, and the treatment effect of row cover on field emergence of 20 forbs native to the Great Basin. Implemented at three sites in 2013 and 2014, forb seeds were sown at four planting depths within the expected variation of the Kemmerer Rangeland or Truax Rough Rider drills.

Increasing Native Forb Seed Supplies for the Great Basin

Publications Posted on: May 12, 2016
Over the last 150 years, excessive grazing, annual weed invasions, increased wildfire frequency, and other human disturbances have negatively impacted native plant communities of the Great Basin. Native plant materials and appropriate planting strategies are needed to recreate diverse communities in areas requiring active restoration. Although native forbs are critical components of most plant communities, available seed supplies remain low.

Great Basin Native Plant Selection and Increase Project: FY2010 Progress Report

Publications Posted on: October 04, 2011
The Interagency Native Plant Materials Development Program outlined in the 2002 Report to Congress (USDI and USDA 2002), USDI Bureau of Land Management programs and policies, and the Great Basin Restoration Initiative encourage the use of native species for rangeland rehabilitation and restoration where feasible.

Tolerance of seven native forbs to preemergence and postemergence herbicides

Publications Posted on: November 18, 2009
Native forb seed is needed to restore rangelands of the Intermountain West. Commercial seed production is necessary to provide the quantity of seed needed for restoration efforts. A major limitation to economically viable commercial production of native forb seed is weed competition. Weeds are adapted to growing in disturbed soil, and native forbs are not competitive with these weeds.

Optimal seeding depth of five forb species from the Great Basin

Publications Posted on: September 25, 2009
Use of forbs in revegetation projects in the Great Basin is limited due to high seed cost and insufficient understanding of their germination and establishment requirements. We tested the effects of seeding depth from 0 to 25.4 mm (1 in) on emergence and survival in clay and sandy loam soils of 5 ecologically important forbs. Significantly less emergence occurred of gooseberry-leaf globemallow (Sphaeralcea grossulariifolia (Hook. &.

Impacts of habitat alterations and predispersal seed predation on the reproductive success of Great Basin forbs

Publications Posted on: August 12, 2009
Sexual reproductive success in wild plant populations is dependent upon the ability to bank seed for when environmental conditions favor seedling recruitment. Seed production in many plant populations requires the pollination services of local bee populations.
