Wild insect pollination has significant positive effects on pollinator-dependent crop production. To assess the spatial distribution of potential wild insect pollination, we mapped the supply of potential wild pollinator habitat (forest, grassland, wetland, and shrubland land cover types) and the demand for pollination (directly pollinator-dependent crops). A foraging travel distance for temperate native bees (1308 meters) was used to identify wild pollinator habitat that is within foraging range of pollinator-dependent crops, and pollinator-dependent crops that are within foraging range of pollinator habitat. Version 2.0 provides an update to the previous version with the inclusion of data from 2013, 2016, and...

Total recreational birding activity (by state and year) estimated by the National Survey for Fishing, Hunting, and WIldlife-Associated Recreation was spatially distributed using birding observations reported through the eBird citizen science database and summarized by land cover type for each analysis year (2001, 2006, 2011, and 2016). Version 2.0 provides an update to the previous version with the inclusion of data from 2016.

Natural land cover can remove pollutants from runoff water by slowing water flow and physically trapping suspended particles. We identified natural land cover in the Southeast US potentially contributing to water purification due to its location in the flowpath between sources of nonpoint-source pollution and waterways. Version 2.0 provides an update to the previous version with the inclusion of data from 2013, 2016, and 2019.

Ecosystems benefit people in many ways, but these contributions do not appear in traditional national or corporate accounts so are often left out of policy- and decision-making. Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), track the extent and condition of ecosystem assets and the flows of ecosystem services they provide to people and the economy. While ecosystem accounts have been compiled in a number of countries, there have been few attempts to develop them for the United States. We explore the potential for ecosystem accounting in the United States by compiling ecosystem condition and ecosystem services supply and use accounts...
