Comprehensive Assessment of Seeded Restoration Species: Factors Controlling Establishment and Persistence in Three Physiographic Regions
Kari Veblen, Eric Thacker, Jason Vernon, Danny Summers, Kevin Gunnell, Tom Monaco, and Joe Robbins

 This project will evaluate the success of restoration plant materials over a broad range of ecological sites throughout Utah. Our assessment also provides critical information to compare the cost effectiveness of restoration treatments and seeding. Our effort will also quantitatively assess the performance of species based on biological traits, which can be used to enhance plant material development and influence seeding success over both short and long-term periods.

Assessing the role of these factors across physiographic regions that experience high temporal and spatial variability in environmental conditions will reveal the effectiveness of various pre-seeding land treatments and enhance our capacity to select appropriate restoration species for specific ecological sites based on their seeding establishment and persistence.

Given this assortment of sites, restoration treatments, and seeded species, we propose to assess the relative success of seeded grass, forb, and shrub species as part of an ongoing effort to determine environmental and ecological factors controlling sagebrush ecosystem restoration.


  • Determine the separate and combined effects of soils, environmental parameters, restoration treatments, seeding techniques, and livestock/wildlife use on species establishment and persistence.
  • Decipher the association between species traits and seedling establishment and persistence in the field, and
  • quantify the cost effectiveness and efficiency of these seeding efforts.
