Agricultural Land in the Western United States

Agricultural land cover for the western United States. This dataset was developed from Sagestitch, the Eastern Washington Shrubsteppe Mapping Project, and several state level GAP products (AZ, CA, NM, OR, and WA).

Long-term monitoring data from eastern screech owl populations in northern Ohio, 1944-1971

Data include population information of eastern screech owl (Megascops asio, formerly Otus asio) populations in four counties of northern Ohio. Researchers recorded adult and chick color phases, eggs laid, brood size and location.

Mercury and biogeochemical parameters in surface water and sediment from U.S. National Parks, 2014-2015

Comma-separated values (.csv) file containing data related to mercury and biogeochemical parameters in surface water and aquatic sediment collected from U.S. National Parks in 2014-2015.

Total mercury and methylmercury in biota from Cottage Grove Reservoir and the Coast Fork Willamette River, Oregon, 2021

Comma-separated values (.csv) file containing data related to mercury in biota from Cottage Grove Reservoir, and the rivers upstream of Cottage Grove Reservoir, Oregon.

Distribution, frequency, and global extent of hypoxia in rivers

To assess the distribution, frequency, and global extent of riverine hypoxia, we compiled 118 million paired dissolved oxygen (DO) and water temperature measurements from 125,158 unique locations in rivers in 93 countries and territories across the globe. The dataset also includes site characteristics derived from StreamCat, the National Hydrography and HydroAtlas datasets and proximal land cover

Vegetation and soil cover data for long-term monitoring plots within Browns Park National Wildlife Refuge, Colorado, USA

Sixty-eight monitoring plots within the Browns Park National Wildlife refuge in Northwest Colorado were surveyed in the Summer of 2007 and 2021 for vegetation-community changes after grazing cessation in 1986. Surveys consisted of line-point intercept measurements at 0.5m intervals along three 15-m transects arranged in a spoke around plot center at each plot location.

Anticoagulant rodenticide concentrations in blood and tissue of California condors and turkey vultures

The dataset includes specifics on liver tissue and blood plasma anticoagulant rodenticide concentrations measured using high-performance liquid chromatography-tandem mass spectrometry.

Reestablishing a foundational species: limitations on post-wildfire sagebrush seedling establishment

This dataset contains observations used to better understand the initial establishment of sagebrush (Artemisia sp.), in the first 1-2 years post-wildfire. Field data come from 460 sagebrush populations sampled across the Great Basin and many GIS-derived co-variates are included as well.

Modelled functional group vegetation cover from 2016 to 2020 on the Soda Wildfire

These rasters represent plant cover during each of the first five growing seasons after fire in the area burned in the 2015 Soda wildfire. Specifically included cover layers are annual herbaceous, perennial herbaceous, shrub, exotic annual grass, and bareground. Training data for each year was collected via grid-point intercept monitoring between April and August. Empirical Bayesian Kriging Regres

Demographic model inputs and code, catchment area population estimates, and counterfactual (CIU) estimates for population growth for 23 focal bird species.

Renewable energy production can kill birds, but little is known about how it affects avian populations. We assessed vulnerability of populations for 23 priority bird species killed at wind and solar facilities in California, USA.

Fishes of the Harney Basin revisited: A contemporary assessment of the distribution of fish fauna throughout the Harney Basin from 1990 to 2019 (ver. 2.0, April 2022)

We compiled electrofishing and habitat data sampled from 1990 to 2019 in the Harney Basin by the US Geological Survey (USGS), Oregon Department of Fish and Wildlife (ODFW) and the High Desert Partnership (HDP) to describe native and non-native fish distributions and their habitat associations. USGS collected eDNA data in 2019 to refine the known distributions of common carp (Cyprinus carpio). Site

Okanogan Basin Pacific lamprey eDNA detections and translocations for 2012-2020 (ver. 1.1, April 2022)

Prior to the initiation of translocation efforts in 2017, Pacific lamprey (Entosphenus tridentatus) were last documented in the Okanogan river subbasin in 2010. It appears as if lamprey were extirpated in the Okanogan subbasin some time shortly after that. However, until 2017, monitoring and management actions for lamprey were minimal in the Okanogan subbasin. This lack of monitoring has resulted
