Restoration and Ecology of Arid Lands (REAL) Laboratory
(We put the R in FRESC)
Joint Fire Science Project (SageSTEP)
The main objective of this study is to identify conditions
that determine the transition between healthy and unhealthy
sagebrush plant communities, specifically related to threats
posed by cheatgrass invasion and woodland encroachment.
And to define thresholds (points at which plant communities
transition to an unhealthy state that may be irreversible.
We hope to accomplish this by evaluating effects of land
management options (fire, mechanical thinning, and
herbicide) on sagebrush communities threatened by cheatgrass
invasion or woodland encroachment.
Integrated Restoration Strategies (IRS)
The
overall goal of this project is to identify concepts and
management strategies to control the spreading dominance of
cheatgrass and other weeds on Great Basin rangelands and to
restore native species and increase biodiversity.
Emergency Fire Rehabilitation Project
Fire
rehabilitation programs have existed within federal agencies
since the early 1960’s. Recent investigation indicate that
both the USFS and BLM, the largest users of ESR funds only
sporadically implement proposed monitoring, and rarely use
common protocols for monitoring (GAO 2003). Therefore, it is
impossible to draw scientifically credible conclusions
regarding the effectiveness of ESR projects. Currently, data
are stored in field office files and are not available for
others to use in deciding on appropriate and effective
techniques to apply on similar areas.
This project is
investigating using a common approach and methodology to
assess the effectiveness of ES&R projects region wide.
Additionally, the project is developing a web-based database
that can act as a central repository of monitoring
information. Data gathered using a common approach would
help address GAO concerns by monitoring multiple projects
with comparable methods, consistently documenting results,
creating and maintaining a central database for query and
reporting, and ultimately determining the effectiveness of
post-fire rehabilitation activities region-wide.

Coordinated Intermountain
Restoration Project (CIRP)
The Coordinated Intermountain Research
Project (CIRP) evolved from the Intermountain Greenstripping
and Rehabilitation Research Project (IGRRP), which was
established by the Idaho State Office, Bureau of Land
Management, in 1982, to select plant materials and
technologies to reduce wildfire incidence and improve
rehabilitation practices. Research and technical assistance
associated with CIRP will emphasize the restoration of
native species on rangelands that are infested with exotic
annual grasses or other invasive or noxious weeds. To
accomplish this objective, the project will promote the
understanding of disturbance dynamics along with selecting
plant materials, site preparation techniques, weed control
methods, seeding equipment, management methods, and
monitoring techniques for restoration projects. CIRP will
not address the restoration of forested or woodland
(juniper) ecosystems. It will include a component on fuels
management to reduce the impacts of wildfires on semi-arid
rangeland ecosystems where exotic annual grasses provide the
fuel. The people who will benefit directly from this
research includes land managers and users of public and
private lands in the northern Great Basin, the Columbia
Plateau, and the Snake River Plain. CIRP will provide an
integration framework for a multi-disciplinary approach to
research with numerous opportunities for input and
collaboration.

Descriptions
Slickspot peppergrass
Lepidium papilliferum Habitat Study
Slick spots are
alkali or sodic soil inclusions in an area that has a matrix
of more normal soil properties. They are called slick spots
because they have a high level of sodium which can
deflocculate the soil resulting in a smooth surface that has
little vegetation. Relatively high concentrations of clay
and salt and reduced levels of organic matter and nutrients
characterize slick spots. Slick spots are generally small
in size, less than 200 m2, and may be less than 1 m2. Slick
spots in southern Idaho are receiving attention because of
slick spot peppergrass Lepidium papilliferum (L.
Henderson) A. Nels and J.F Macbr. This rare plant is found
in the northern Great Basin on the Snake River Plain, Owyhee
Plateau, and adjacent foothills in south-western Idaho
(Mancuso 2000). The concern over slickspot peppergrass
arises from its relatively high rate of extirpation. The
plant can be impacted by a variety of activities including
wildfire and fire rehabilitation activities, encroachment of
non native plants, some cattle and sheep grazing practices,
gravel mining, irrigated agriculture and urbanization
(Moseley 1994 and Meyer 1996).
The objectives of
this study were to determine the effects on slick spots of
common restoration techniques used in the Great Basin, such
as, reseeding of native grasses using a Rangeland Drill and
the application of herbicide. Using high resolution aerial
photography we are monitoring effects these restoration
techniques have on slick spots, the primary habitat of slick
spot peppergrass.
