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!

Small Alpine Insects are Big Messengers of Climate Change

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.

Multidirectional abundance shifts among North American birds and the relative influence of multifaceted climate factors

Shifts in species distributions are major fingerprint of climate change. Examining changes in species abundance structures at a continental scale enables robust evaluation of climate change influences, but few studies have conducted these evaluations due to limited data and methodological constraints. In this study, we estimate temporal changes in...

Molecular systematics of swifts of the genus Chaetura (Aves: Apodiformes: Apodidae)

Phylogenetic relationships among swifts of the morphologically conservative genus Chaetura were studied using mitochondrial and nuclear DNA sequences. Taxon sampling included all species and 21 of 30 taxa (species and subspecies) within Chaetura. Our results indicate that Chaetura is monophyletic and...

Natural resource managers who oversee the Nation’s resources require data to support informed decision-making at a variety of spatial and temporal scales that often cross typical jurisdictional boundaries such as states, agency regions, and watersheds. These data come from multiple agencies, programs, and sources, often with their own methods and...
