Ecosystems—whether agricultural, urban, or natural—depend on pollinators, great and small. Pollinators in the form of bees, birds, butterflies, bats, and even moths provide vital, but often invisible services, from contributing to biodiverse terrestrial wildlife and plant communities to supporting healthy watersheds. Pollinator declines worldwide have been noted as land-use and climate changes occur on the landscape. USGS is laying the groundwork for better scientific understanding of wildlife population level impacts from a variety of potential threats to species from big game to birds, to bats, to pollinators.

Influence of land use in the northern Great Plains on honey bee health and pollination service delivery, NPWRC (2015-2017) Influence of land use in the northern Great Plains on honey bee health and pollination service delivery, NPWRC (2015-2017)
Land use within a 4-km radius around 36 apiaries in North Dakota, South Dakota, and Minnesota was quantified over two years, 2015-16 and 2016-17. The area (hectares) of Ag (corn, soy, small grains), Grass (pasture, grassland, fallow land, wildflowers, shrub land, and hay land), Wetlands (herbaceous and woody), and Bee crops (alfalfa, canola, sunflower) were quantified around each apiary...

Using colony monitoring devices to evaluate the impacts of land use and forage quality on honey bee health datasets Using colony monitoring devices to evaluate the impacts of land use and forage quality on honey bee health datasets
Honey bee colonies located in 2 apiaries in North Dakota were fitted with two types of monitoring device: pollen traps and scales. Data were collected from devices periodically throughout the 2014 season (May-October). Data derived from pollen traps included: the total fresh weight of pollen collected, the percent crude protein content, the percent content of each amino acid, and DNA
Radio telemetry data on nighttime movements of two species of migratory nectar-feeding bats (Leptonycteris) in Hidalgo County, New Mexico, late-summer 2004 and 2005 Radio telemetry data on nighttime movements of two species of migratory nectar-feeding bats (Leptonycteris) in Hidalgo County, New Mexico, late-summer 2004 and 2005
These bat location estimates have been reported by Bogan and others (In press) and come in the form of a GIS shape file. Three species of nectar-feeding phyllostomid bats migrate north from Mexico into deserts of the United States (U.S.) each spring and summer to feed on blooms of columnar cacti and century plants (Agave spp). However, the habitat needs of these important desert...
Soil, geomorphology and pre-European settlement vegetation associations of Southwest Louisiana Soil, geomorphology and pre-European settlement vegetation associations of Southwest Louisiana
Defining the pre-European range of vegetation communities can enhance our understanding of the role soil, hydrology, and climate had on climax plant communities within southwest Louisiana. Coastal prairie grasslands were in a perpetual state of succession due to two primary disturbances; grazing, primarily by bison and other ungulates, and fires ignited by lightning and Native Americans...
Grassland quality and pollinator habitat potential in Southwest Louisiana Grassland quality and pollinator habitat potential in Southwest Louisiana
Potential pollinator habitat was derived by ranking land use classifications and grassland quality based on ground truthing and remotely sensed features indicative of remnant prairie. High resolution (10m) land use data served as the basemap (Hartley et al 2017) from which most categories were identified. All known prairie remnants, prairie plantings, and clusters of mima mounds were...

Field-level exposure of bumble bees to fungicides applied to a commercial cherry orchard Field-level exposure of bumble bees to fungicides applied to a commercial cherry orchard
Bumble bees, Bombus spp. (Apidae), are important native pollinators; however, populations of some species are declining in North America and agricultural chemicals are a potential cause. Fungicides are generally not highly toxic to bees, but little is known about sublethal or synergistic effects. This study evaluates bumble bee exposure to fungicides by quantifying concentrations of...

Populations of bumble bees and other pollinators have declined over the past several decades due to numerous threats, including habitat loss and degradation. However, we can rarely investigate the role of resource loss due to a lack of detailed long‐term records of forage plants and habitats.We use 22‐year repeated surveys of more than 262 sites located in grassland, forest, and wetland...

Roadside rights-of-way as pollinator habitat: A literature review Roadside rights-of-way as pollinator habitat: A literature review
Pollination of crops and naturally-occurring flowering plants is a critical ecosystem service provided by managed and unmanaged animal pollinators. Insects are the most studied pollinators, particularly managed honey bees, unmanaged wild bees, and butterflies. Bees and butterflies thrive in early-successional habitat featuring grasses, exposed soil, wildflowers, and shrubs, which is...

Beyond neonicotinoids – Wild pollinators are exposed to a range of pesticides while foraging in agroecosystems Beyond neonicotinoids – Wild pollinators are exposed to a range of pesticides while foraging in agroecosystems
Pesticide exposure is a growing global concern for pollinator conservation. While most current pesticide studies have specifically focused on the impacts of neonicotinoid insecticides toward honeybees and some native bee species, wild pollinators may be exposed to a broader range of agrochemicals. In 2016 and 2017 we collected a total of 637 wild bees and butterflies from the margins of...

Toward improving pollinator habitat: Reconstructing prairies with high forb diversity Toward improving pollinator habitat: Reconstructing prairies with high forb diversity
Reconstructed prairies can provide habitat for pollinating insects, an important ecosystem service. To optimize reconstructions for pollinators, goals may include enhancing flowering plant cover and richness and increasing bloom availability early and late in the growing season. Resistance to invasive exotic species must also be a goal in any reconstruction, but it is unclear how...

Forage and habitat for pollinators in the northern Great Plains—Implications for U.S. Department of Agriculture conservation programs Forage and habitat for pollinators in the northern Great Plains—Implications for U.S. Department of Agriculture conservation programs
Managed and wild pollinators are critical components of agricultural and natural systems. Despite the well-known value of insect pollinators to U.S. agriculture, Apis mellifera (Linnaeus, 1758; honey bees) and wild bees currently face numerous stressors that have resulted in declining health. These declines have engendered support for pollinator conservation efforts across all levels of...

Wildfire reveals transient changes to individual traits and population responses of a native bumble bee (Bombus vosnesenskii) Wildfire reveals transient changes to individual traits and population responses of a native bumble bee (Bombus vosnesenskii)
1. Fire-induced changes in the abundance and distribution of organisms, especially plants, can alter resource landscapes for mobile consumers driving bottom-up effects on their population sizes, morphologies, and reproductive potential. We expect these impacts to be most striking for obligate visitors of plants, like bees and other pollinators, but these impacts can be difficult to...
