Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Evaluating bias in roadside surveys of secretive marsh birds in the Prairie Pothole Region, MN, ND, and SD 2008-2009 Evaluating bias in roadside surveys of secretive marsh birds in the Prairie Pothole Region, MN, ND, and SD 2008-2009
The data set consists of data to evaluate bias in roadside surveys of secretive marsh birds in 2008 and 2009 in wetlands in the Prairie Pothole Region of Minnesota, North Dakota, and South Dakota during three survey periods (survey number). The data set includes detection values (species heard, species seen, species seen and heard) of seven focal marsh bird species (four-letter alpha...
Pesticide Water-Quality Data Associated with Arundo donax (Arundo Cane) Treatment on a Section of the Rio Grande in Webb County, Texas, 2020 Pesticide Water-Quality Data Associated with Arundo donax (Arundo Cane) Treatment on a Section of the Rio Grande in Webb County, Texas, 2020
Arundo donax (Arundo Cane) is an invasive perennial reed that can grow more than 30 feet tall and has become established in riparian zones along rivers throughout the southwestern United States. It grows in thick stands, readily displaces native riparian habitat, and provides no habitat or food for native species in the ecosystems it disrupts (McWilliams, 2004). The Texas State Soil and...
Land Cover Assignments of 300 locations in the Pacific Northwest in 2000 Land Cover Assignments of 300 locations in the Pacific Northwest in 2000
Area estimates of land cover and land cover change are often based on reference class labels determined by analysts interpreting satellite imagery and aerial photography. Different interpreters may assign different reference class labels to the same sample unit. This dataset include land cover attributes for the year 2000 assigned by 7 image analysts, working independently of each other...
CO2 concentrations and microbial biomass data derived from incubation experiments on soils collected at Arches National Park in 2017 and 2018 CO2 concentrations and microbial biomass data derived from incubation experiments on soils collected at Arches National Park in 2017 and 2018
These data were compiled to improve our understanding of how water, carbon (C), nitrogen (N), and phosphorus (P) interact to regulate below ground carbon cycling. Objective(s) of our study were to evaluate how soil heterotrophic carbon cycling responded to inputs of water, C, N, and P individually and interactively on the Colorado Plateau. These data represent soil microbial and CO2...

Ecotypic Variation in Ambrosia dumosa and Larrea tridentata from Three Sites Across the Mojave (2014 - 2018) Ecotypic Variation in Ambrosia dumosa and Larrea tridentata from Three Sites Across the Mojave (2014 - 2018)
These data were acquired from two native Mojave Desert species, Ambrosia dumosa and Larrea tridentata, from 3 sites (50 m x 50 m garden plots) distributed across the differing Mojave Desert ecotones. These sites were located on the Fort Irwin National Training Center (CA), north of Joshua Tree National Park (CA), and north of Saint George (UT). Growth and survivorship data were collected...
