Between 2009 and 2018, scientists conducted a national scale assessment of mercury accumulation in the National Park System using dragonfly larvae as biosentinels (species that accumulate a pollutant in their tissues as an index of exposure to other organisms without significant adverse effects to the biosentinel) through a citizen science network called the Dragonf

Photovoltaic, or solar, cells array at the Ivanpah Solar Power Facility in the Mojave Desert and a wind energy facility in the Northeastern United States.

A completed restoration field trial site just after installation. Half of the site is seeded, and the other half had plants and weed cloth (white fabric) installed.

These workers are planting seedlings as part of the restoration field trial network. Each garden in the network is examining seedlings and seeds in conjunction with restoration treatments to better und

A Pallid bat (Antrozous pallidus) is outfitted with a radio transmitter to help lead us to its roost. The transmitter is attached with a temporary adhesive that will wear off within around 2 weeks, about as long as the battery life of the transmitter lasts.

The RestoreNet gardens test seedlings of priority restoration species across the Southwest. This is a recently installed garden located in the juniper woodlands of the Colorado Plateau. The experiemental network will support land managers by providing insight into various restoration techniques, including testing seedlings vs seeds.

Throughout Hawaii, fishponds are considered by their local communities as important cultural touchstones, a source of local, sustainably produced food, and an important component to the development of community-based management for nearshore fisheries.

Hawaiian fishponds were important cultural and economic resources for native Hawaiians as they were an important component of a sophisticated, integrated food production system. However, changing demographics and systems of land ownership resulted in a decline in the use and upkeep of Hawaiian fishponds throughout the 19th century.

Many bumble bee species have declined in recent decades due to changes in habitat, climate, and pressures from pathogens, pesticides and introduced species. The western bumble bee, once common throughout western North America, is a species of concern and is being considered for listing by the U.S. Fish and Wildlife Service under the Endangered Species Act.
