Our study aims to understand the chemical composition of rainwater collected from 48 sites in 31 states throughout the United States, including Alaska and Hawaii.
Sonoran scrub oak grows in semiarid, lower elevation chaparral, pinyon-juniper (Pinus-Juniperus spp.), shrub deserts, oak woodlands, ponderosa pine (P. ponderosa) and riparian communities of the Southwest.
Mineral development on National Forest System (NFS) lands is a temporary use of those lands, and requires adequate fiscal resources be available to ensure that reclamation of the mineral sites are integral to any development proposal. As a result, the Forest Service has identified a mechanism for addressing post-closure long-term liabilities associated with large mining activities on NFS lands.
The response of desert plant assemblages to disturbance was studied in Death Valley National Monument, California. Plant assemblages on debris flows, alluvial terraces, five abandoned townsites, and a pipeline corridor were measured to quantify recovery rates and to develop a model of change in desert vegetation.
The proposed conceptual model helps predict BSC distribution within intermontane basins to identify biologically sensitive areas, set reference conditions for ecological restoration, and potentially enhance arid landscape models, as scientists address impacts of climate change and anthropogenic disturbances.
The scope of this memo includes a critical evaluation of the setup, calibration, application and predictions of the M&A (2020a) Skunk Camp TSF groundwater flow and transport model, including the related inputs from the KCB (2020) seepage model.
This technical memorandum summarizes conceptual level sampling locations, sampling frequency, and laboratory testing to be conducted on tailings and the associated decant pond.
