Monitoring
Access RAP App.
The Rangeland Analysis Platform (RAP) is an innovative online mapping tool that can be used by anyone—no fees or registration required. The tool provides quick snapshots of rangeland vegetation. It allows users to easily compare trends in rangeland resources through time at a ranch, county, or watershed scale.

The Rangeland Analysis Platform (RAP) is a free, online tool that helps landowners and natural resource managers track vegetation through time and plan actions to improve America’s grazing lands. The RAP can be used to provide strategies to improve productivity of grazing lands, manage weeds, mitigate impacts of wildfire and drought, and benefit wildlife habitats. Powered by Google Earth Engine, RAP merges machine learning and cloud-based computing with remote sensing and field data to provide the first-ever annual cover maps of rangeland vegetation. This new platform allows people to view trends in rangeland resources at an unprecedented blend of space (from the Great Plains to the Pacific Ocean), time (1984 to present), and scale (at the ranch, watershed, or county level). Designed to be combined with local knowledge, the RAP helps users better understand vegetation change through time to aid in conservation planning and outcome evaluation. This webinar will describe the innovative breakthrough in mapping vegetation cover and demonstrate RAP applications.

State-of-the-art mountaintop cameras from the University of Nevada, Reno, a new and expanding tool for fire mangers who oversee the wildland and wildland/urban interface, spotted or tracked 240 fires in Nevada and California in 2017, helping to keep firefighters more situationally aware and able to mount appropriate responses more rapidly over tens of thousands of square miles of forests and rangelands, including rural communities.

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.
