Restoration potentials and challenges for Sphaeralcea munroana

Publications Posted on: February 05, 2013
Munro’s globemallow (Sphaeralcea munroana [Douglas] Spach) is an herbaceous perennial and an important candidate for use in restoration due to its ecological significance and environmental resilience. The species’ popularity among growers and land managers has recently increased but there is still a lack of information regarding seed dormancy and early seedling physiology, making the effective use of the species difficult.

Demographic processes limiting seedling recruitment in arid grassland restoration

Publications Posted on: October 04, 2012
Seeding is an important management tool in aridland restoration, but seeded species often fail to establish. Previous research has largely focused on the technical aspects of seeding with little effort directed at identifying demographic processes driving recruitment failures.

Managing soil nitrogen to restore annual grass-infested plant communities: Effective strategy or incomplete framework?

Publications Posted on: October 04, 2012
Theoretical and empirical work has established a positive relationship between resource availability and habitat invasibility. For nonnative invasive annual grasses, similar to other invasive species, invader success has been tied most often to increased nitrogen (N) availability. These observations have led to the logical assumption that managing soils for low N availability will facilitate restoration of invasive plant-dominated systems.

A collaborative program to provide native plant materials for the Great Basin

Publications Posted on: October 04, 2012
The Great Basin as defined on a floristic basis includes the hydrographic Great Basin plus the Owyhee Uplands and Snake River Plain of southern Idaho (Fig. 1). The region encompasses about 60 million ha, of which more than two-thirds are publicly owned. Vegetation ranges from salt desert and sagebrush shrublands in the basins to conifer forests in the more than 200 mountain ranges.

Structural organization of process zones in upland watersheds of central Nevada and its influence on basin connectivity, dynamics, and wet meadow complexes

Publications Posted on: September 05, 2012
The drainage network within upland watersheds in central Nevada can be subdivided into distinct zones each dominated by a unique set of processes on the basis of valley form, the geological materials that comprise the valley floor, and the presence or absence of surficial channels.

GSD Update: All together now: Collaboration in research and stewardship for our 21st century lands

Publications Posted on: July 31, 2012
Collaboration is the way the USDA Forest Service operates in this new era, where the challenges in our natural world - to soil, air, plants, animals, watersheds - require the talents of devoted scientists, managers, citizens, communities. Conservation of terrestrial and aquatic ecosystems depends on the success of these networks of involved participants in finding answers to present and future problems.

Great Basin Native Plant Selection and Increase Project: 2011 Progress Report

Publications Posted on: June 06, 2012
The Interagency native Plant Materials Development Program outlined in the 2002 Report to Congress (USDI and USDA 2002), USDI Bureau of Land Management programs and policies, and the Great Basin Restoration Initiative encourage the use of native species for rangeland rehabilitation and restoration where feasible.

Great Basin Native Plant Selection and Increase Project: FY2010 Progress Report

Publications Posted on: October 04, 2011
The Interagency Native Plant Materials Development Program outlined in the 2002 Report to Congress (USDI and USDA 2002), USDI Bureau of Land Management programs and policies, and the Great Basin Restoration Initiative encourage the use of native species for rangeland rehabilitation and restoration where feasible.

Phenotypic and genetic characterization of western prairie clover collections from the western USA

Publications Posted on: October 04, 2011
Few North American legumes are available for rangeland revegetation in the semiarid western United States. Western prairie clover (Dalea ornata [Douglas ex Hook.] Eaton & J. Wright) is a perennial legume with desirable forage characteristics and is distributed in the northern Great Basin, Snake River Basin, and southern Columbia Plateau.

Influences of watershed geomorphology on extent and composition of riparian vegetation

Publications Posted on: September 27, 2011
Watershed (drainage basin) morphometry and geology were derived from digital data sets (DEMs and geologic maps). Riparian corridors were classified into five vegetation types (riparian forest, riparian shrub, wet/mesic meadow, dry meadow and shrub dry meadow) using high-resolution aerial photography. Regression and multivariate analyses were used to relate geomorphic characteristics to riparian vegetation extent and composition.
