This paper describes the ongoing development of a comprehensive set of vegetation reference conditions based on over 900 quantitative vegetation dynamic models and accompanying description documents for terrestrial ecosystems in the USA. These models and description documents, collaboratively developed by more than 800 experts around the country through the interagency LANDFIRE Program, synthesize fundamental ecological information about ecosystem dynamics, structure, composition, and disturbance regimes before European-American settlement. These products establish the first comprehensive national baseline for measuring vegetation change in the USA, providing land managers and policymakers with a tool to support vegetation restoration and fuel management activities at regional to national scales. Users have applied these products to support a variety of land management needs including exploring ecosystem dynamics, assessing current and desired conditions, and simulating the effects of management actions. In an era of rapid ecological change, these products provide land managers with an adaptable tool for understanding ecosystems and predicting possible future conditions.
View synthesis.
This synthesis contains 14 chapters that cover fire and forests, machinery, erosion processes, water yield and quality, soil and riparian impacts, aquatic and landscape effects, and predictive tools and procedures. These chapters provide an overview of our current understanding of the cumulative watershed effects of fuel management in the western United States.
Rangeland drills are commonly employed for post fire rehabilitation and emergency stabilization. With the assumption that adverse effects will occur, archaeological sites are flagged and avoided. This may cause a site stranding effect and greater potential for post fire erosion. To better understand and quantify the effects we evaluated four archaeological sites characterized as lithic scatters. Artifacts were documented and point-plotted using sub-centimeter GPS technology, subjected to drill seeding, and subsequently replotted and reevaluated. This presentation will detail the methods and results of this study and thoughts for future application. This webinar was presented by Kirk Halford, BLM, Boise.
View report.
This report examines the needs for native plant restoration and other activities, provides recommendations for improving the reliability, predictability, and performance of the native seed supply, and presents an ambitious agenda for action. An Assessment of Native Seed Needs and the Capacity for Their Supply considers the various challenges facing our natural landscapes and calls for a coordinated public-private effort to scale-up and secure a cost-effective national native seed supply.

View report.
In developing this report, a cross-functional group of stakeholders and subject matter experts (SMEs) from across the nation convened to identify 33 challenges within 13 key WUI issues and develop recommendations to address each challenge. In total, 112 recommendations are presented. These recommendations address challenges in firefighter health and safety, public health and safety, evacuations, forest and rangeland health and resiliency, climate change, community planning and resiliency, infrastructure and utilities, communication strategy and engagement operations, socioeconomic impacts, recovery, emerging technology, data use and modeling, and risk management in wildland fire. The recommendations should be pursued together, forming a system of strategies that require urgent, sustained and actionable implementations. These recommendations are not quick fixes, but solutions for the long term. Leadership on and commitment to the implementation of these recommendations results in a safer America.

The GBLCC Conservation Planning Atlas (CPA) is an important aspect of our effort to engage a landscape focus and best available science toward improving collaboration and maximizing conservation efforts in the Great Basin. Incorporating over 1000 spatial data layers related to conservation of the Great Basin region’s many natural and cultural resources, the CPA provides managers, researchers and planners from state, federal, local, NGO and private partners a valuable suite of tools for collaborative spatial planning. In short, the portal represents a single website to access regional spatial layers, decision support tools, and Great Basin LCC project information and products.
GBLCC’s Geospatial Data Specialist, Eric Jensen will be joined by Conservation Biology Institute’s Kai Henifin to share about the CPA. Together we will dive into navigation of the portal, data, tools and publications available, and the Data Basin suite of collaborative features—such as Groups, sharing and comment threads. Finally, we’ll explore current use cases and share information about how you or your group can leverage the CPA for your own projects and planning.

This paper highlights greater sage-grouse egg depredation observations obtained opportunistically from three common raven nests located in Idaho and Nevada where depredated greater sage-grouse eggs were found at or in the immediate vicinity of the nest site, including the caching of eggs in nearby rock crevices. Nests were opportunistically monitored by counting and removing depredated eggs and shell fragments from the nest sites during each visit to determine the extent to which the common raven pairs preyed on greater sage-grouse eggs. These observations may represent the first evidence that breeding, territorial pairs of common ravens cache greater sage-grouse eggs and are capable of depredating multiple greater sage-grouse nests.

Results of this study indicate that native grasses more readily establish in synchrony with crested wheatgrass than native shrubs, but once established, native shrubs are more likely to coexist and persist with crested wheatgrass because of high niche differentiation (e.g., not limited by the same resource). Results also suggest that developing strategies to minimize interference from crested wheatgrass seedlings emerging from seed banks will enhance the establishment of native species seeded into crested wheatgrass–dominated communities.
