Effects of Soil Nutrients and Fire on Seedling Establishment of Native Prairie Species

Creator:: Clark, Deborah Louise, 1950-
Abstract:: We sought to determine 1) the relationship between seedling establishment rates of target native prairie species and field levels of three soil nutrients (phosphate, nitrate, and ammonium) recorded in fall, winter, and summer, 2) the effect of fire on these three nutrients, and 3) the overall effect of fire on...

Seed and seedling ecology of Artemisia tridentata in a restoration context

Creator:: Wijayratne, Upekala C.
Abstract:: The semi-arid sagebrush steppe ecosystem is one of the largest biomes in North America. The steppe provides critical habitat and forage for wildlife and is economically important to recreation and livestock industries. However, the ecosystem is threatened primarily due to several negative effects associated with expansion of the exotic annual...

Winterfat seed viability and dormant season livestock grazing

Creator:: Leary, Ryan
Abstract:: Krascheninnikovia lanata (winterfat) is a valuable forage species with an average of 10% crude protein during winter when there are few nutritious options for livestock and wildlife. However, excessive grazing throughout the west has negatively impacted survival of winterfat stands. We hypothesized that four years rest from dormant season livestock...

Seed bank response to juniper expansion in the semi-arid lands of Oregon, USA

Creator:: Duncan, Corinne M.
Abstract:: Expansion of Juniperus occidentalis into the sagebrush steppe has resulted in significant changes in understory composition. A consequence of increased J. occidentalis dominance may be a depletion of the seed bank. The potential for depletion is problematic because a reduction in the amount of species available from the seed bank...

Quantification of state-and-transition model components utilizing long-term ecological response data following one-seed juniper treatment on a deep sand savannah ecological site

Creator:: Shaver, Patrick L.
Abstract:: A proposed state-and-transition model (STM) for the Deep Sand Savannah ecological site in central New Mexico was developed using historical data and expert knowledge. This STM was tested utilizing data from short and long term one-seed juniper (Juniperus monosperma (Engelm.) Sarg.) control experiments initiated in 1981 and 1985. Utilizing data...

Activated carbon incorporated into herbicide protection pods as a seed amendment technology for revegetation

Creator:: Clenet, Danielle R.
Abstract:: Reestablishing native perennial vegetation in annual grass-invaded rangelands is critical to restoring ecosystems, especially following wildfires. Controlling invasive annual grasses is essential to increasing revegetation success; however, pre-emergent herbicides used to control annual grasses prohibit immediate seeding due to non-target herbicide damage. Thus, seeding is often delayed one year following...

Are Early Summer Wildfires an Opportunity to Revegetate Exotic Annual Grass–Invaded Plant Communities?

Creator:: Davies, Kirk W., Nafus, Aleta M., and Johnson, Dustin D.
Abstract:: Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Successful revegetation of invaded-plant communities can be prohibitively expensive because it often requires iterative applications of integrated control and revegetation treatments. Prescribed burning has been used to control medusahead and prepare seedbeds for revegetation, but burning has...

Nutritional characteristics of dormant season grazing within a winterfat (Krascheninnikovia lanata (Gueldenstaedt)) dominated plant community, and the effect of seedbed preparation on the emergence and survival of winterfat and squirreltail (Elymus elymoides (Raf.) Swezey) seedlings

Creator:: Estes, Mark G.
Abstract:: The effect of seedbed preparation on the emergence and survival of winterfat (Krascheninnikovia lanata (Gueldenstaedt)) and squirreltail (Elymus elymoides (Raf.) Swezey)) seedlings was determined, while quantifying nutritional changes through the dormant season for four range species. In November of 2004 twenty 9m x 8m plots were randomly prepared with one...

Restoration of Annual Grass-invaded Landscapes in the Sagebrush Steppe using Perennial Grass Seed Technologies and Wyoming Big Sagebrush Transplanting

Creator:: Holfus, Corinna M.
Abstract:: Within the sagebrush steppe ecosystem, invasive annual grasses are of growing management concern as they outcompete native vegetation, change the fundamental nutrient cycling processes, decrease biodiversity, and increase frequency of wildfires. The most widely used and effective management tool to decrease invasive annual grass abundance, is the use of pre-emergent...
