This dataset presents the spatial results of an aquatic integrity assessment conducted by the Conservation Biology Institute (CBI) in the Rogue River, southern Oregon coastal streams, Klamath River, and upper Sacramento River basins. This assessment integrated measures of road density, road-stream crossings, percentage forest change within watersheds, and mining activity. This particular dataset integrated two separate analyses: one for the Rogue River and southern Oregon coastal streams area, and another for the Klamath and upper Sacramento River area. These two analyses used slightly different methods. Model results from the individual analyses were normalized before integrating into this dataset. Ordinal scores...
A warming climate could profoundly affect the distribution and abundance of many fishes. Bull trout (Salvelinus confluentus) may be especially vulnerable to climate change given that spawning and early rearing are constrained by cold water temperatures creating a patchwork of natal headwater habitats across river networks. Because the size and connectivity of patches also appear to influence the persistence of local populations, climate warming could lead to increasing fragmentation of remaining habitats and accelerated decline of this species. We modeled the relationships between (1) the lower elevation limits of small bull trout and mean annual air temperature and (2) latitude and longitude across the species...
Project Synopsis: the strategy for restoring the habitat on Currant Creek is to permanently exclude unauthorized livestock from the stream and adjacent meadows unless livestock are authorized in the special use pasture. Livestock are only to be permitted to graze every 3rd year for 3 weeks or as approved by authorized officer. (It's been about ten years since grazing has been authorized in the area due to resource concerns.) The most imminent threat to the currant creek habitat is continual cattle drift into the drainage. This results in the unauthorized grazing of riparian vegetation and BLM projects such as willow, aspen, and other woody species plantings. The area is important habitat (ACEC area) for Colorado...

This dataset was created as a way to have standard fish distribution datasets across the various fish species for the study area. This was needed because the original source datasets for fish distributions came from several different sources and were at various scales and also overlapped. To fix the issues in the source datasets we walked the original data over to the NHD Plus hydrography.

This table contains information about the amount of each threat analysis attribute, indicator and metric quantified for the 6th level Hydrological Unit (HUC12). These attributes were calculated for the entire HUC 12, the streams within the HUC 12, or the riparian corridor within the HUC 12. The attributes were calculated using ArcMap Tools.

A strong data foundation is needed to inform science-based decisions for fisheries management at a watershed level. In preparation for a shift towards comprehensive watershed-scale planning, Arizona Game and Fish Department (AGFD) is developing a fisheries data management system with an initial focus on compiling and formatting several hundred thousand fish survey and stocking records. Fish data will be integrated within a Geographic Information System (GIS) by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which will allow for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by state boundaries. In...

Abstract: Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010–11. U.S. Geological Survey Fort Collins Science Center (FORT) scientists collected an assemblage of biotic, abiotic, and hydrologic data from Topock Marsh during the drawdown and immediately after, thus obtaining valuable information needed by FWS. Building upon that work,...

Aquatic Planning Units are derived from the U.S. Geological Survey (USGS) National Hydrography Dataset (NHD)+ v. 2 catchments. They contain information used throughout the NatureScape (landscape conservation design) development. The tables include summaries of information within each catchment including predictor variables. See SI.

Compilation of seagrass (submerged aquatic vegetation (SAV) ) from digital benthic habitat data created by National Ocean and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC) from existing digital multi-spectral imagery (ADS-40). NOAA worked cooperatively with Texas Parks and Wildlife Department (TPWD) and the Texas A&M University Center for Coastal Studies to develop benthic habitat data for several Texas coastal bays. This data will support the state's recently adopted Seagrass Monitoring Program which calls for regional mapping of seagrass for status and trends assessment. More information about the Ecosystems Integration and Assessment Priority Issue Team is available...
Convert impenetrable sheep fence to more "wildlife friendly" fence to allow passage of pronghorn and other big game species. Provide a number of low-tech erosion and water harvesting measures to improve two-track roads. Construct small rock mulches to improve water infiltration while reducing runoff and soil erosion. With the assistance of the Wyoming Youth Conservation Corp, conduct fence repair and reconstruction. Plant willow and other shrubs. This project would increase the amount and diversity of riparian and transitional riparian/upland habitats. Establishment and expansion of woody species such as willow in riparian areas would provide increased fish stream shading, and armoring of stream banks from erosion....
