These heatmaps show a top 3 stressor or service, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor or service across the landscape. This map shows the percentage of participants from each county and municipality who ranked Bermuda Grass (Cynodon dactylon) as a top 3 ecosystem stressor in the Riparian Invasive Plant category in their region. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for...

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 identification of floral plant sources. Scales collected colony weight through time.

The project aimed to use existing models and data to understand how wildfires (number, size, and location) and land-use change will affect watersheds, and therefore water supply, under current conditions and future climates (through 2050) in the western U.S. The projected changes in temperature and precipitation are expected to affect water supply in two major ways: 1) decreased water availability, and 2) increased risk to watersheds via loses from fire. As the western population is projected to grow by 310 million people by 2100, this will potentially increase demand for diminishing supplies if housing growth occurs in rangelands or forested lands. Understanding watershed vulnerabilities due to changing climate,...

In the border region between Mexico, Arizona and New Mexico, a little known landscape supports a unique mix of temperate and subtropical ecosystems, the likes of which are found nowhere else in the United States. The Sky Islands are an area of more than 40 separate mountain ranges isolated by what was once a sea of more than 13 million acres of grassland. It is one of America’s hotspots for wildlife diversity, hosting more than twice as many mammal species as Yellowstone National Park and supporting the nation’s highest diversity of reptiles, bees, and ants. Additionally, these grasslands are a key connecting landscape between the Sierra Madre Occidental Mountains in Mexico and the Rocky Mountains to the North and...

Reports describe research by Iowa State University in collaboration with Neal Smith National Wildlife Refuge and other partners has discovered that strategically adding a little bit of prairie back onto the agricultural landscape can result in many benefits – for water and soil quality, habitat for wildlife and pollinators, as well as opportunities for biomass production. With assistance from ETPBR member USDA Farm Service Agency, research has shown how small amounts of native prairie vegetation integrated within corn and soybean row crops produce environmental benefits at levels disproportionately greater than their extent and in a cost effective manner. The project has now transitioned to demonstration and evaluation...

The Hudson River, New York, was contaminated with polychlorinated biphenyls (PCBs) from two General Electric plants over a period of ~30 years and PCBs are still present in sediment and biota today. The river provides habitat for a variety of plants and animals, including native freshwater mussels. Although little is known about mussels in this river, managers were concerned that a 7-year remediation program to remove PCB-contaminated sediments could affect mussels. From 2013-2019, we conducted stratified (non-remediated, before remediation, after remediation) quantitative surveys across 17-pool-stratum combinations across nine pools. Sampling was done during August through October of each year. At each site, divers...
Interest in the utilization of forest biomass for energy is growing. A search into existing forest biomass harvesting and regeneration guidelines was carried out to identify how biomass energy can be environmentally sustainable. Findings have shown that there are only a few guidelines that specifically address harvesting and regenerating biomass for bioenergy or other bio-based products. Of these few, there are guidelines developed for dedicated energy plantations such as the Scottish Agricultural College guidelines, as well as some Finnish and Swedish guidelines recommending management practices for both timber and biomass extraction. Most of the existing small woody material guidelines emphasize the retention,...

Total water demand (gallons per day per acre) summarized to 12-digit HUC watersheds was derived from EnviroAtlas agricultural, domestic, industrial, and thermoelectric water demand datasets.Information about the original EPA data is as follows:Agricultural water demand:The EnviroAtlas national water demand metric provides insight into the amount of water currently used for agricultural irrigation in the contiguous United States. The values are based on 2005 irrigation water use; combined 2010 crop, 2006 land use, and 2001 remotely sensed irrigation location estimates; and have been summarized by watershed or 12-digit hydrologic unit code (HUC). Agricultural irrigation water use, as defined in this case, meets a...
Overgrazing and fire suppression have led to a loss of deep soils and vegetative cover in the 420,000 acre Alamosa Creek watershed in southwestern New Mexico. Rain and snow melt are no longer held by the soils and released slowly, but run off in floods, resulting in catastrophic flows and severe erosion that contribute sediment to Elephant Butte Dam. The diverse community of farmers that irrigate 800 acres of valley land on 49 farms in Cañada Alamosa are looking to revive traditional and develop innovate new practices to maintain their way of life. Partnerships are required to design new land management practices between scientists and local land managers. This project is a component of a larger Alamosa Land Institute...

Ecosystem accounts link national-scale environmental and economic trends, offering an internationally standardized approach to tracking sustainability. We compile ecosystem accounts for Rwanda over a 25-year period, and demonstrate that despite strong economic growth, social development, and high-level commitment to environmental goals, ecosystem services fundamental to Rwanda's well-being have declined substantially during this period. Conversion of forests and other natural ecosystems to cropland are the primary drivers of these trends. Ecosystem accounts are particularly important for tracking sustainability in African nations with high levels of economic and population growth and rapid environmental change....

This EnviroAtlas dataset contains data on the mean synthetic nitrogen (N) fertilizer application to cultivated crop and hay/pasture lands per 12-digit Hydrologic Unit (HUC) in 2006 (EA_SNFA_Mean attribute). Synthetic N fertilizer inputs in 2006 were estimated using county-level estimates of farm N fertilizer inputs. We acquired county-level data describing total farm-level inputs (kg N/yr) of synthetic N fertilizer to individual counties in 2006 from the United States Geological Survey (USGS) (http://pubs.usgs.gov/sir/2012/5207/). These data were converted to per area rates (kg N/ha/yr) of synthetic N fertilizer application by dividing the total N input by the land area (ha) of combined cultivated crop and hay/pasture...
