Users, Uses, and Value of Landsat Imagery

Users, Uses, and Value of Landsat Imagery

Landsat satellites provide high-quality, imagery of urban, rural, and remote lands for all areas of the world. The imagery is applied to a variety of research areas, such as climate change research, agriculture, and environmental management.

Burmese Pythons Invade the Everglades

The Florida Everglades encompass a vast subtropical ecosystem. Billions of dollars have been committed to the long-term restoration of this ecosystem, but burgeoning populations of introduced and invasive reptiles threaten prospects for restoration.

New Research Highlights Decline of Greater Sage-Grouse in the American West, Provides Roadmap to Aid Conservation

RESTON, Va. – Greater sage-grouse populations have declined significantly over the last six decades, with an 80% rangewide decline since 1965 and a nearly 40% decline since 2002, according to a new report by the U.S. Geological Survey. Although the overall trend clearly shows continued population declines over the entire range of the species, rates of change vary regionally.

The Transformation of dryland rivers: The future of introduced tamarisk in the U.S.

Tamarix spp. (tamarisk or saltcedar), a shrub-like tree, was intentionally introduced to the U.S. from Asia in the mid-1800s. Tamarisk thrives in today’s human-altered streamside (riparian) habitats and can be found along wetlands, rivers, lakes, and streams across the western U.S. In 2001, a biological control agent, Diorhabda spp. (tamarisk leaf...

Range-wide greater sage-grouse hierarchical monitoring framework—Implications for defining population boundaries, trend estimation, and a targeted annual warning system

Incorporating spatial and temporal scales into greater sage-grouse (Centrocercus urophasianus) population monitoring strategies is challenging and rarely implemented. Sage-grouse populations experience fluctuations in abundance that lead to temporal oscillations, making trend estimation difficult. Accounting for stochasticity is critical to...

Sagebrush conservation strategy—Challenges to sagebrush conservation

The sagebrush (Artemisia spp.) biome, its wildlife, and the services and benefits it provides people and local communities are at risk. Development in the sagebrush biome, for many purposes, has resulted in multiple and often cumulative negative impacts. These impacts, ranging from simple habitat loss to complex, interactive changes in ecosystem...
