Streams are classified as perennial (flowing uninterrupted, year-round) or intermittent (flowing part of the year) or ephemeral (flowing only during rainfall events). The classifications of “streamflow permanence” were primarily established in the middle 20th century and are often outdated and inaccurate today if they were not adjusted for changes in land use, wildfires, or climate. Understanding where streams are perennial is important for a variety of reasons. For example, perennial streams receive special regulatory protections under a variety of statutes, and provide important habitat for fish, wildlife, and other species. To predict the likelihood that streams are perennial, we compiled nearly 25,000 observations...
Western Native Trout Initiative (WNTI) proposes to collaborate with the Southern Rockies Landscape Conservation Cooperative (SRLCC) in conducting a conservation assessment of the U.S. Rio Grande Valley to determine areas appropriate for the efficient implementation of habitat-related projects and identify priority watersheds to improve ecological condition, restore natural processes, and prevent the decline of intact and healthy systems. This will be accomplished through strategic conservation planning that includes multi-species concerns, broad landscapes benefits, a data-driven approach, persistence of all priority species’ populations, and human land use. Analogous conservation assessments have been completed...

This conservation assessment of the U.S. Rio Grande Watershed identifies target areas for the implementation of habitat-related projects and priority areas, stream segments, and watersheds to improve ecological condition, restore natural processes, and prevent the decline of intact and healthy systems. Through systematic conservation planning, this assessment addresses multi-species and multi-jurisdictional concerns; work that complements and extends analogous conservation assessments completed for much of the Desert Landscape Conservation Cooperative’s (DLCC) extent. In doing so, it provides a flexible working model into which priority taxa and habitats can be easily incorporated in the future.

Significant progress has been made toward the recovery of the threatened Apache Trout. Major threats were removed including hybridization, logging, and overharvest. Remaining threats are being managed and are manageable. Partners agree that it is time to evaluate if the Apache Trout still warrants protection under the Endangered Species Act (ESA). The Apache Trout is a “conservation-reliant species,” meaning that it will need continued active population- and threat-management related to predation and competition from nonnative trout species. Therefore, a long-term CMP is essential to analyzing the species’ status relative to potential delisting. An Apache Trout SSA and CMP are both prerequisite documents needed...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
