Seventy-five years of vegetation treatments on public rangelands in the Great Basin of North America
View article.
This article summarizes information from land treatments occurring over millions of hectares of public rangelands in the Great Basin over the last 75 years represent one of the largest vegetation manipulation and restoration efforts in the world.

This brief was developed to help guide collaborative landscape planning efforts, through use of a framework of seven core principles and their implications for management of fire-prone interior forest landscapes.
Key findings included:
- Historically, forests were spatially heterogeneous at multiple scales as a result of interactions among succession, disturbance, and other processes.
- Planning and management are needed at fine to broad scales to restore the key characteristics of resilience.
- Landscapes must be viewed as socio-ecological systems that provide services to people within the limited capacities of ecosystems.
- Development of landscape-level prescriptions is the foundation of restoration planning.

This study found that higher moss cover will be achieved quickly with the addition of organic matter and when moss fragments originate from sites with a climate that is similar to that of the restoration site.

The Integrated Rangeland Fire Management Strategy outlined the need for coordinated, science-based adaptive management to achieve long-term protection, conservation, and restoration of the sagebrush (Artemisia spp.) ecosystem. A key component of this management approach is the identification of knowledge gaps that limit implementation of effective strategies to meet current management challenges. The tasks and actions identified in the Strategy address several broad topics related to management of the sagebrush ecosystem. This science plan is organized around these topics and specifically focuses on fire, invasive plant species and their effects on altering fire regimes, restoration, sagebrush and greater sage-grouse (Centrocercus urophasianus), and climate and weather.

This study concluded that, although increases in native species could possibly be obtained by repeating crested wheatgrass control treatments, reducing crested wheatgrass opens a window for invasion by exotic weed species.

This research brief reports that applying salvaged biocrust material to severely disturbed soil rapidly reestablished favorable biocrust characteristics and stabilized soil more than doing nothing. This is likely a useful restoration strategy when unavoidable soil disturbances are planned and there are opportunities to salvage material.

This study investigated the effects of container volume and fertilization on the performance of nursery-grown Wyoming big sagebrush seedlings following outplanting. Researchers found that container volume may influence seedling morphology and optimize establishment, while field fertilization, especially during spring outplanting when planting sites have low moisture availability, may hinder first-year survival.
