Resilience of crested wheatgrass stands: implications for rangeland seedings and structural diversity by Tom Monaco, ARS Forage and Range Research Lab

  1. 1. THE FORAGE AND RANGE RESEARCH LABORATORY PLANTS FOR THE WEST THE FORAGE AND RANGE RESEARCH LABORATORY Utah State University, Logan, Utah Resilience  of  crested   wheatgrass  stands  :   implica5ons  for   rangeland  seedings  and   structural  diversity   Thomas  Monaco,  Ecologist  
  2. 2. THE FORAGE AND RANGE RESEARCH LABORATORY Presentation Outline PLANTS FOR THE WEST 1. Background: What novel changes have occurred to upland and semiarid shrub ecosystems in the Great Basin? 2. Case Study: Characteristics of shrublands historically seeded with crested wheatgrass. 3. Five-Year Field Experiment: Can crested wheatgrass stands be modified to favor greater diversity? Disturbance and reintroduction of species

  13. 13. THE FORAGE AND RANGE RESEARCH LABORATORY Crested wheatgrass resilience PLANTS FOR THE WEST …suppression treatments were not effective and therefore did not improve restoration of native species in crested wheatgrass stands. Native species establishment may require subsequent management to favor persistence of native species and retard crested wheatgrass. (Fansler and Mangold 2011). … crested wheatgrass recovered to similar cover percentages as untreated plots 2–3 yr after wheatgrassreduction treatments. Effective wheatgrass control may require secondary treatments to reduce the seed bank and open stands to dominance by seeded native species (Hulet et al. 2010).
  14. 14. THE FORAGE AND RANGE RESEARCH LABORATORY Research Design/methods PLANTS FOR THE WEST Two sites in southern Idaho - duplicated in 2009 and 2010 Pre-treatment: 1 or 2 year - Mowing to prevent seed dispersal - Herbicide (glyphosate) to kill plants Seeding: grasses, forbs, shrubs

  24. 24. THE FORAGE AND RANGE RESEARCH LABORATORY Conclusions PLANTS FOR THE WEST 1. Reducing seed dispersal was critical to reduce crested wheatgrass recovery 2. Herbicide applications improved seedling emergence and establishment 3. Due to mortality of seeded species over time, it may be necessary to seed again
