Data

This USGS data release consists of six data sets and accompanying metadata for a year-long study on the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, critical habitat for two endangered Maui endemic forest birds. Culex quinquefasciatus is the vector of the avian malaria Plasmodium relictum, a key limi

In July 1992 soils were sampled from six dune fields in the northern Lower Peninsula of Michigan near Wilderness State Park, about 10 miles southwest of Mackinaw City. The dune fields represent a soil chronosequence, where all soil forming factors except time are held constant (climate, organisms, relief, and parent material). These sandy lake terrace soils are Entisols and Spodosols (Podzols), wi

The Massachusetts Drought Management Plan (DMP, 2023) uses data from select lake and impoundment systems as an index for drought in six of seven regions in the state. The contents of these lakes and impoundments are reported to Massachusetts Department of Conservation and Recreation (DCR) and classified as one of five levels for drought severity ranging from level 0 (Normal; percentile greater tha

The occurrence and impact of the February 2023 earthquake doublet in Türkiye, where an Mw 7.8 event was followed roughly 9 hours later by an Mw 7.5 event on an adjacent fault, begs the question: What would be the impact of such a sequence in California? As part of the effort to address this question, this Data Release consists of simulated ground motions for a hypothetical doublet scenario on the

The 1966-2023 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly 24.5 miles

Nest number, description of nest structure and location, longitude, latitude, dates of observations, presence of adults, eggs, nestlings, outcome of reproductive effort, number of young fledged, and osprey nest platforms occupied by Canada geese.

The data release for geologic maps of Ravalli Group and other Mesoproterozoic Belt Supergroup strata in northern Idaho and northwestern Montana is a digital, Geologic Map Schema (GeMS)-compliant version of maps published in U.S. Geological Survey (USGS) Open-File Report 2001-438 (Boleneus and others, 2001). The new digital data present attribute tables and geospatial features (points, lines, and p

Early studies of soil formation highlighted several key factors that together determine the degree of soil pedogenesis, which include climate, organisms (including vegetation), topography, and parent material (Jenny H.; 1941; Factors of Soil Formation, a System of Quantitative Pedology; https://doi.org/10.2134/agronj1941.00021962003300090016x). A soil chronosequence is defined as a series of soils

The purpose of this project is to determine the infectious status and exposure status of several diseases that have the potential to impact the health of greater sage grouse (Centrocercus urophasianus) captured in Montana, USA to be translocated to Alberta, Canada. Specific disease status to be tested include, infection with avian influenza virus (AIV), infection with Avian Paramyxovirus-1 (APMV1)

These CLIM-MET stations are meteorological/geological stations that is designed to function in remote areas for long periods of time without human intervention. These stations measure meteorological and wind-erosion parameters under varying climatic and land-use conditions to detect and describe ongoing landscape changes. These data represent multiple years of local detailed landscape and environm

To better inform fuel break planning and assessment, we developed a comprehensive spatial database of known existing fuel breaks from 1953 to 2018 throughout the western United States. Each fuel break is represented as a polygon in the database and is attributed with the date of installation, the treatment type employed, and the data source. The availability of these data promotes the development
