Status and Trends Program
To protect, conserve, and restore the living resources—plants, animals, habitats, ecosystems—entrusted to their care, land and resource managers must understand the condition, or status (e.g., abundance, distribution, productivity, health), of those resources as well as their trends (i.e., how these variables change over time).
How do we know it's spring?
The First Leaf and First Bloom Indices are synthetic measures of these early season events in plants, based on recent temperature conditions. Get weekly updates about spring leaf out and blooms from the National Phenology Network!Find out more

West Glacier, Mont. – Two rare alpine insects – native to the northern Rocky Mountains and dependent on cold waters of glacier and snowmelt-fed alpine streams – are imperiled due to climate warming induced glacier and snow loss according to a study by the U.S. Geological Survey and its partners.
With the White House’s launch of CitizenScience.gov and the inaugural Citizen Science Day this Saturday April 16, 2016, the U.S. Geological Survey invites you to look into a landscape of opportunities to participate in science!
Nesting loggerhead sea turtles in the northern Gulf of Mexico feed among areas that were oiled by the 2010 Deepwater Horizon spill and where human activities occur, several of which are known to pose threats to sea turtles, a new U.S Geological study showed.
Integrating Breeding Bird Survey and demographic data to estimate Wood Duck population size in the Atlantic Flyway
The U.S. Fish and Wildlife Service (USFWS) uses data from the North American Breeding Bird Survey (BBS) to assist in monitoring and management of some migratory birds. However, BBS analyses provide indices of population change rather than estimates of population size, precluding their use in developing abundance-based objectives and limiting...Zimmerman, Guthrie S.; Sauer, John; Boomer, G.

Identifying key climate and environmental factors affecting rates of post-fire big sagebrush (Artemisia tridentata) recovery in the northern Columbia Basin, USA
Sagebrush steppe of North America is considered highly imperilled, in part owing to increased fire frequency. Sagebrush ecosystems support numerous species, and it is important to understand those factors that affect rates of post-fire sagebrush recovery. We explored recovery of Wyoming big sagebrush (Artemisia tridentata ssp.wyomingensis)...Shinneman, Douglas; McIlroy, Susan
American woodcock migratory connectivity as indicated by hydrogen isotopes
To identify factors contributing to the long-term decline of American woodcock, a holistic understanding of range-wide population connectivity throughout the annual cycle is needed. We used band recovery data and isotopic composition of primary (P1) and secondary (S13) feathers to estimate population sources and connectivity among natal, early...Sullins, Daniel S.; Conway, Warren C.; Haukos, David A.; Hobson, Keith A.; Wassenaar, Leonard I; Comer, Christopher E.; Hung, I-Kuai
