The National Stream Internet (NSI) is a network of people, data, and analytical techniques that interact synergistically to create information about streams. The NSI is needed because accurate, high-resolution status and trend information does not exist for most biological and water quality attributes across the 5.5 million stream kilometers in the United States.
Wet meadow ecosystems host threatened and endangered species and are at high risk from climate change, wildfires, and water diversion. A typical wet meadow in the upper Middle Fork Salmon River, Idaho is the site of several prior and current investigations of stream ecosystem dynamics.
The Valley Confinement Algorithm (VCA) is a GIS based program that uses NHDPlus data to delineate unconfined valley bottoms. This webpage provides access to the VCA ArcGIS Toolbox script and documentation describing the program.
The Interior West Forest Inventory and Analysis (FIA) Program collects increment cores as part of regular monitoring. Ring-widths from these increment cores are being digitized and assembled into data products for biogeographical or climatological analyses.
