Supporting the development and use of native plant materials for restoration on the Colorado Plateau (Fiscal Year 18 Report) Supporting the development and use of native plant materials for restoration on the Colorado Plateau (Fiscal Year 18 Report)
Introduction A primary focus of the Colorado Plateau Native Plant Program (CPNPP) is to identify and develop appropriate native plant materials (NPMs) for current and future restoration projects. Multiple efforts have characterized the myriad challenges inherent in providing appropriate seed resources to enable effective, widespread restoration and identified a broad suite of research...

Genetic analyses of Astragalus sect. Humillimi (Fabaceae) resolve taxonomy and enable effective conservation Genetic analyses of Astragalus sect. Humillimi (Fabaceae) resolve taxonomy and enable effective conservation
Premise of the Study Astragalus sect. Humillimi is distributed across the southwestern United States and contains two endangered taxa, A. cremnophylax var. cremnophylax and A. humillimus. The former was originally described from the South Rim of the Grand Canyon. Analysis of individuals discovered on the North Rim of the Grand Canyon yielded some evidence that the population represented...

Population history provides foundational knowledge for utilizing and developing native plant restoration materials Population history provides foundational knowledge for utilizing and developing native plant restoration materials
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. In the western United States, Pseudoroegneria spicata (bluebunch wheatgrass; Poaceae) is an important component of grassland...

Beyond traditional ecological restoration on the Colorado Plateau Beyond traditional ecological restoration on the Colorado Plateau
The Colorado Plateau is one of North America's five major deserts, encompassing 340,000 km2 of the western U.S., and offering many opportunities for restoration relevant to researchers and land managers in drylands around the globe. The Colorado Plateau is comprised of vast tracts of public land managed by local, state, and federal agencies that oversee a wide range of activities (e.g...
