Status and Trends

Program Relevance

The Nation’s living resources and the habitats on which they depend are undergoing constant change. Climate change, invasive species, and a plethora of human activities are causing natural resource management and conservation efforts to become increasingly challenging and complex. To help meet this challenge, USGS’s Status and Trends of Biological Resources Program supports and provides the collection and analysis of biological data for use by natural resource managers, scientists, and the general public.

waterfall

To protect and conserve the living resources entrusted to their care, land and resource managers must first understand the condition, or status, of those resources:
• inventory (what they are),
• distribution (where they are located),
• abundance (how many there are),
• productivity (their capacity to produce),
• health (their well-being, resilience)
and then understand the trends being exhibited by those resources
• variables change over time and space.

Did You Know...?

Amphibians & Reptiles

Antarctica is the only continent that has no native amphibian species. Amphibians and reptiles are very important vertebrates on the Pacific Islands. Surprisingly, given their importance, there are only six reptiles native to the Hawaiian Islands and all of them live in the sea. The rest of Hawaii's reptiles and amphibians are invaders. Learn more about amphibians from the NBII Pacific Basin Information Node website

Feature

Louisiana Coastal Land Loss was approximately 1,900 square miles, primarily coastal marshes, during the 20th century. Louisiana could lose another 700 square miles over the next 50 years if no new restoration takes place. By 2050, one third of coastal Louisiana will have vanished into the Gulf of Mexico.

Biological Inventory and Monitoring

Biological Inventory and Monitoring (I&M) is an essential tool to understand the status and trends of plant and animal populations, as well as, to help us to see large-scale patterns of ecosystem health, so vital to the survival of humans and all species.

Biological inventory is the obtaining and compiling of data regarding plant and animal species to gain knowledge of what species exist, where they are located, how many there are, and the state of their health.

For effective management of plant and animal populations to occur, these factors need to be monitored both in the "here and now" and over the long-term in order to detect trends in the status of these populations. As species population trends are identified, management protocols can be adjusted.

Publications

River One of the goals of Status and Trends of Biological Resources is to provide Web-accessible reports and publications to advance greater understanding, interpretation, and use of status and trends information.

Featured on our publications page are pdfs of our strategic plan and program brochure as well as links to many other Status and Trends publications and reports.
