Data represent presence/absence for cedar decline occurrence. Cedar decline refers to the dying or decline of yellow-cedar (Chamaecyparis nootkatensis) forests in Southeast Alaska and is characterized by red or yellow foliage in trees currently dying, or by white-gray snags of old mortality. Mapped snags can be standing dead as long as eighty years. The data were collected via aerial sketch mapping techniques and recorded on 1:250,000 USGS base maps from 500-3000 foot above ground level(AGL) observations. Survey coverage has been most intense for forests adjacent to shorelines and waterways. Data are collected, refined and updated on an annual basis. This data represent not one year's mortality but the cumulative...

This dataset provides a watershed index of surface drinking water importance, a watershed index of forest importance to surface drinking water, and a watershed index to highlight the extent to which development, fire, and insects and disease threaten forests important for surface drinking water. This symbology for this layer is based on the index value for insect and disease threat to forests which are important to surface drinking water on a range from 1-100.

The citizen science pilot began in April of 2023 and ends in November of 2023. Based on the response and number of specimens received the collection efforts may continue into 2024. The Lepidoptera Research Collection (LRC) will be made available to all scientists within the USGS to conduct research. States included in the pilot study (Nebraska, Kansas, Oklahoma, Texas, Georgia, and Alabama) were selected based on at least one of three factors: 1) locality relative to the migration pathway of the Monarch butterfly, 2) presence of confined animal feeding operations (CAFOs), or 3) locality relative to the Corn Belt. The Environmental Organic Chemistry (EOC) unit, located at the Kansas Water Science Center, will specifically...

The Forest to Faucets dataset provides a watershed index of surface drinking water importance, a watershed index of forest importance to surface drinking water, and a watershed index to highlight the extent to which development, fire, and insects and disease threaten forests important for surface drinking water. This layer displays the percent of the HUC watershed that is threatened bu insects and disease. For further information, see the methods paper titled, "From the Forest to the Faucet: Drinking Water and Forests in the US" located at http://www.fs.fed.us/ecosystemservices/FS_Efforts/forests2faucets.shtml.

These data were collected to fulfill multiple Inter-agency agreements established by US Geological Survey and multiple partners: US Department of Agriculture-Farm Service Agency, USDA Natural Resources Conservation Service, and the Honey Bee Health Coalition. In this study USGS scientists conducted floral resource and insect pollinator assessments across multiple land covers in North Dakota, South Dakota, and Minnesota from 2015 to 2019. Sampling was done along 2x20m transects in June through September by a single observer. All transects were located on private or public grasslands such as Conservation Reserve Program (CRP) lands, Environmental Quality Incentives Program (EQIP) lands, managed pasture, haylands,...
