This study informs researchers and practitioners seeking to optimize terrestrial laser scanning (TLS) sampling methods for vegetation monitoring in dryland ecosystems through three analyses. First, we quantify the 2D extent of occluded regions based on the range from single scan positions. Second, we measure the efficacy of additional scan positions on the reduction of 2D occluded regions (area) using progressive configurations of scan positions in 1 ha plots. Third, we test the reproducibility of 3D sampling yielded by a 5-scan/ha sampling methodology using redundant sets of scans. Analyses were performed using measurements at analysis scales of 5 to 50 cm across the 1-ha plots, and we considered plots in grass and shrub-dominated communities separately.

This project inventoried 97 projects implemented by 32 organizations, most in the last 10 years. We found that beaver-related stream restoration projects undertaken mostly involved the relocation of nuisance beavers. The most common goal was to store water, either with beaver dams or artificial structures. Beavers were often moved without regard to genetics, disease, or potential conflicts with nearby landowners. Few projects included post-implementation monitoring or planned for longer term issues, such as what happens when beavers abandon a site or when beaver dams or structures breach. Human dimensions were rarely considered and water rights and other issues were mostly unresolved or addressed through ad-hoc agreements. We conclude that the practice and implementation of beaver-related restoration has outpaced research on its efficacy and best practices. Further scientific research is necessary, especially research that informs the establishment of clear guidelines for best practices.

Bruce Wylie and Stephen Boyte, USGS, discuss their recent research mapping herbaceous annual cover in the Great Basin. This webinar was hosted by the Great Basin LCC.
- Restoring & managing “Emerald Isles”
- Strategic, multi-scale approach for managing threats to sagebrush ecosystems based on resilience and resistance concepts
The Society for Range Management’s 71st Annual Meeting, Technical Training and Trade Show was at the Nugget Hotel in Sparks, Nevada. The theme for the 2018 conference was Empowerment through Applied Science.
Many inventory and assessment projects spanning large landscapes, the entire Great Basin, or the western US, have been completed recently or are underway for key natural resources. This special session of the 4th Great Basin Consortium Conference brought together leaders of these efforts to compare/contrast their efforts and create a synthesis product or “table of contents” for geospatial data users.

2/10/14 – Workshop 1: ESD Uses and Users, provides examples of ESD uses in diverse ecosystems throughout the United States. This workshop is a showcase of the increasing development and use of ESDs for all land types.
2/11/14 – Workshop 2: Unifying Concepts for Riparian Ecological Sites, focuses on advancing ESD concepts for riparian ecosystems, which differ from upland systems in the degree to which hydrology drives ecosystem dynamics. This riparian ESD workshop is part of a larger effort to advance the conceptual framework of ESDs in riparian systems, and will present the current state of RCESD concepts and provide opportunities for input from a broad audience.

The CONSERVATION EFFORTS DATABASE (CED) was codeveloped by the U.S. Fish and Wildlife Service (USFWS), the U.S. Geological Survey (USGS), and the Great Northern Landscape Conservation Cooperative (GNLCC):
- USFWS provided a comprehensive ecological assessment separated by threats and efforts, and database structure based on user needs.
- USGS provided database and website design expertise building off of the Land Treatment Digital Library.
- GNLCC provided ecological, database, and GIS expertise, greatly enhancing CED capabilities.
Many state and federal partners provided input and feedback, ranging from design recommendations to policy sideboards, ensuring the CED has broad applicability and interoperability.
This chapter reviews some of the conceptual and technological advancements and provide examples of how they have influenced rangeland monitoring. It then discuss implications of these developments for rangeland management and highlight what are seen as challenges and opportunities for implementing effective rangeland monitoring. It concludes with a vision for how monitoring can contribute to rangeland information needs in the future.
