Land Treatment Exploration Tool
The Land Treatment ExplorationTool provides a practical resource for managers who are planning restoration and rehabilitation actions on public lands. The tool generates a variety of spatial products while being user friendly for all levels of GIS expertise, even to those with little or no experience.
Land Treatment Digital Library
The LTDL was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The...
Land Treatment Digital Library (LTDL)
The Land Treatment Digital Library (LTDL) was created by the USGS to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales.
Data Entry Module for the Land Treatment Digital Library (LTDL)
This software allows agencies, organizations, and individuals to download an empty, stand-alone Land Treatment Digital Library database to individual or networked computers. Data entered in these databases may be submitted to the USGS for possible inclusion in the online Land Treatment Digital Library (https://ltdl.wr.usgs.gov).
Transient population dynamics impede restoration and may promote ecosystem transformation after disturbance
The apparent failure of ecosystems to recover from increasingly widespread disturbance is a global concern. Despite growing focus on factors inhibiting resilience and restoration, we still know very little about how demographic and population processes influence recovery. Using inverse and forward demographic modelling of 531 post‐fire sagebrush...

Adapting management to a changing world: Warm temperatures, dry soil, and interannual variability limit restoration success of a dominant woody shrub in temperate drylands
Restoration and rehabilitation of native vegetation in dryland ecosystems, which encompass over 40% of terrestrial ecosystems, is a common challenge that continues to grow as wildfire and biological invasions transform dryland plant communities. The difficulty in part stems from low and variable precipitation, combined with limited understanding...

Fuels guide and database for intact and invaded big sagebrush (Artemisia tridentata) ecological sites—User manual
The Fuels Guide and Database (FGD) is intended to provide fuel loading and vegetation information for big sagebrush (Artemisia tridentata) ecological sites in the Morley Nelson Snake River Birds of Prey National Conservation Area (hereinafter the NCA) in southern Idaho. Sagebrush ecosystems in the NCA and throughout much of the Great Basin are...
Shinneman, Douglas J.; Welty, Justin L.; Arkle, Robert S.; Pilliod, David S.; Glenn, Nancy F.; McIlroy, Susan K.; Halford, Anne S. An introduction and practical guide to use of the Soil-Vegetation Inventory Method (SVIM) data
Long-term vegetation dynamics across public rangelands in the western United States are not well understood because of the lack of large-scale, readily available historic datasets. The Bureau of Land Management’s Soil-Vegetation Inventory Method (SVIM) program was implemented between 1977 and 1983 across 14 western states, but...

Land treatment exploration tool
OverviewLand managers make decisions regarding restoration and rehabilitation actions that influence landscapes and ecosystems. Many of these decisions involve soil and vegetation manipulations, often known as land treatments. Historically, treatments were planned on a case by case basis with decisions derived from personal experience of past...
Pilliod, David S.; Welty, Justin L.; Jeffries, Michelle I. ; Schueck, Linda S.; Zarriello, Thomas J. Long-term trends in restoration and associated land treatments in the southwestern United States
Restoration treatments, such as revegetation with seeding or invasive species removal, have been applied on U.S. public lands for decades. Temporal trends in these management actions have not been extensively summarized previously, particularly in the southwestern United States where invasive plant species, drought, and fire have altered dryland...
Copeland, Stella M.; Munson, Seth M.; Pilliod, David S.; Welty, Justin L.; Bradford, John B.; Butterfield, Bradley J. The Conservation Efforts Database: Improving our knowledge of landscape conservation actions
The Conservation Efforts Database (CED) is a secure, cloud-based tool that can be used to document and track conservation actions across landscapes. A recently released factsheet describes this tool ahead of the rollout of CED version 2.0. The CED was developed by the U.S. Fish and Wildlife Service, the USGS, and the Great Northern Landscape...
Heller, Matthew M.; Welty, Justin; Wiechman , Lief A. Refining the cheatgrass–fire cycle in the Great Basin: Precipitation timing and fine fuel composition predict wildfire trends
Larger, more frequent wildfires in arid and semi-arid ecosystems have been associated with invasion by non-native annual grasses, yet a complete understanding of fine fuel development and subsequent wildfire trends is lacking. We investigated the complex relationships among weather, fine fuels, and fire in the Great Basin, USA. We first modeled...
Pilliod, David S.; Welty, Justin; Arkle, Robert Seventy-five years of vegetation treatments on public rangelands in the Great Basin of North America
On the Ground 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.The ability to use legacy data from land treatments in adaptive management and ecological research has improved with the...
Pilliod, David S.; Welty, Justin; Toevs, Gordon R. Quantifying restoration effectiveness using multi-scale habitat models: implications for sage-grouse in the Great Basin
A recurrent challenge in the conservation of wide-ranging, imperiled species is understanding which habitats to protect and whether we are capable of restoring degraded landscapes. For Greater Sage-grouse (Centrocercus urophasianus), a species of conservation concern in the western United States, we approached this problem by developing multi-...

Data entry module and manuals for the Land Treatment Digital Library
Across the country, public land managers make decisions each year that influence landscapes and ecosystems within their jurisdictions. Many of these decisions involve vegetation manipulations, which often are referred to as land treatments. These treatments include removal or alteration of plant biomass, seeding of burned areas, application of...

Why Sagebrush Re-establishment After Fire is so Difficult
Big sagebrush ecosystems are particularly sensitive to wildfires and life history information on big sagebrush is scarce and vital for restoration success.
A Database Tool for Estimating Fuel Loadings Across a Range of Intact to Degraded Sagebrush Habitats in Southern Idaho
USGS researchers created an interactive Fuels Guide and Database, providing vegetation and fuel loading information and photographs for big sagebrush (Artemisia tridentata) ecological sites in the Morley Nelson Snake River Birds of Prey National Conservation Area (NCA) in southern Idaho.
Land Treatment Exploration Tool Fact Sheet
Land restoration and rehabilitation efforts usually involve soil and vegetation manipulations, which influence landscapes and ecosystems. These manipulations, or treatments, historically have been planned on a case-by-case basis with decisions made from personal experience of past successes or failures.
Environmental Factors Affect Success of Sagebrush Reseeding Efforts
In the western U.S., big sagebrush ecosystems provide habitat for about 350 species of conservation concern, but are sensitive to disturbance and are in decline. Big sagebrush ecosystems have low and variable precipitation, which makes restoration a challenge.
