One of the greatest challenges facing the Wyoming Game and Fish Department (WGFD) in the 21st century will be our ability to maintain sustainable fish and wildlife populations and meet the expectations and desire of our citizens. We approach habitat conservation and management on a landscape/watershed scale based on the needs of all fish and wildlife and citizens who either enjoy and/or depend on wildlife, and the land and water resources of the State. This requires a great deal of teamwork and a broader view of our responsibilities. Addressing habitat needs and issues that seek to maintain open spaces, non-fragmented, quality habitats and the ability of fish and wildlife to utilize these areas provides an opportunity...

Forest- Data collected once using GIS prior to fish sampling. Our approach was to focus the study on smaller, headwater catchments because larger streams drained areas containing both hemlock and mixed hardwood forest, making forest-specific comparison intractable. In addition, most of these larger watersheds were impacted by humans (e.g., impoundments, agriculture, quarries) that could confound our assessment of the influence of hemlock. Even after limiting the study to headwater catchments, other possible confounding factors remained; we controlled for landscape variability (i.e., terrain and stream size) through the sampling design and we excluded others (i.e., minimum catchment area,beaver activity) through...

Raw data were collected in Shenandoah National Park during summer 2012. Air and temperature data were collected using temperature loggers at several stations throughout the park. These data were used in the publication of the manuscript "Accounting for groundwater influence on headwater stream thermal sensitivity to climate change" through the journal Ecological Applications. Water temperature data were collected at all 78 reach locations during the summer of 2012 (23 June–7 September). Temperature was measured every hour with a logger.

This ScienceBase space provides an array of USGS Series publications, journal articles, and other published references for the Gap Analysis Project (GAP). Information on GAP-related publications can also be found at: https://www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/publications
The data set includes delineation of sampling strata for the six study reaches of the UMRR Program’s LTRM element. Separate strata coverages exist for each of the three monitoring components (fish, vegetation, and water quality) to meet the differing sampling needs among components. Generally, the sampling strata consist of main channel, side channel, backwater, and impounded areas. The fish component further delineates a “shoreline” portion of the strata to be used for sampling gears deployed only along the shoreline. The data are raster in origin, with the center of each pixel representing the sampling location. Cell size is typically 50 meters, although several water quality strata are at 200 meter cell size.

Weed shiners are listed as endangered in Iowa. In the spring of 1990, one weed shiner (Notropis texanus) was collected from the Crooked Slough Complex, Pool 13 (river mile 554.3) of the Upper Mississippi River System. Prior to this study, there is no record of weed shiners collected in Pool 13. After the initial collection, a follow-up search for weed shiners was undertaken during fall 1990, and during late summer and fall 1991, to estimate relative abundance at this site. The Crooked Slough collection site was seined on three separate occasions, and 1,840 fish were collected. No additional weed shiners were captured. Therefore, the collection efforts do not support the hypothesis that the Crooked Slough collection...
The annual variability in mayflies (Ephemeroptera), fingernail clams (Sphaeriidae), and midges (Chironomidae) in six study areas of the Upper Mississippi River System from 1992 to 1995 was examined. Spatial distribution is also discussed for these organisms along with the Asiatic clam (Corbicula fluminea) and the zebra mussel (Dreissena polymorpha). Sample allocation within each reach was based on a stratified random design where strata were aquatic areas. No significant linear trends across years were found in estimated reachwide mean number of organisms. However, the overall test for differences in intercepts among study areas was statistically significant (P < 0.05) for mayflies, fingernail clams, and midges....
Satellite images offer an alternative to aerial photography in mapping applications where large area coverage at brief time intervals is required. Their digital format allows either visual or automated interpretation, with immediate incorporation into a geographic information system. Their primary disadvantage is a coarser spatial resolution. This study combined the benefits of (1) the 10-m spatial resolution of SPOT panchromatic (PAN) images, (2) the added spectral information of Landsat Thematic Mapper's (TM) mid-infrared bands, and (3) digital classifications to map terrestrial and aquatic cover types in the Mississippi and Illinois River floodplains. The PAN and the six non-thermal TM bands were combined using...
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area that has been modeled is called "Montrose Flats." Aquatic vegetation is abundant at this location, and the flow structure needs to be evaluated in order to study the nutrient transport conditions within this area. The present study focused on a large oval eddy that was observed to form in this area near the downstream end of the Devil's Creek delta. Causative factors for this eddy were examined by using this numerical model. Results indicate that the eddy can be simulated by this model and that numerical study is a feasible way to...
Macrophyte populations have recently decreased in the Upper Mississippi River (UMR). This decline may be due to abiotic factors, such as a reduction in nutrients; however, biotic factors are also suspect. The common carp Cyprinus carpio has been reported to affect submerged macrophyte populations in other systems but not in the UMR. This study was conducted to determine if common carp can directly or indirectly reduce submerged macrophyte biomass. Twelve enclosures (25 m2) and four reference sites were constructed in Lawrence Lake, a backwater in the UMR, and stocked with one of three densities (0, 1, 10) of common carp. High densities of common carp (10/enclosure or approximately 7000 kg/ha) significantly reduced...
Since 1988, the Long Term Resource Monitoring Program (LTRMP) has performed basic limnological field measurements in the Upper Mississippi River System. The period of this report (1993 96) includes a major revision of the LTRMP sampling design in 1993 that added randomization, broader spatial coverage, and increased monitoring of tributaries and locations that allow monitoring of material transport. Monitoring by the Lake City Field Station reported here shows water quality differences among the tributaries to Pools 4 and 5, spatial and temporal patterns within these pools, and the sediment and nutrient trapping effects of Lake Pepin, a natural impoundment of the Mississippi River.
This tutorial was prepared for field personnel in the Long Term Resource Monitoring Program (LTRMP) for the Upper Mississippi River System (UMRS) and other river managers who use Environmental Planning and Programming Language version 7 (EPPL7). The data sets included in the tutorial are from the LTRMP geographic information system (GIS) data base, and the exercises cover frequently used GIS procedures.
The Aquatic Habitat Analysis and Visualization Tool is a program and interface that allows users to view and create habitat models using the pre-improvement water quality data collected for the Finger Lakes Habitat Rehabilitation Project (HREP). The Finger Lakes HREP is a hydrologic modification of a backwater lake complex in upper Pool 5 of the Mississippi River. The program and interface were implemented using Arc Macro Language and require the workstation version of ARC/INFO geographic information system software (ESRI, Redlands, CA).
This chapter describes the procedures for digital data entry to be used by the staff at the Environmental Management Technical Center. Included are procedures for creating a coverage, registering a base map, digitizing with an automated program (Production ARCEDIT), generating topology for a coverage, and attributing. The two main issues during this procedure are digitizing error and quality control. The Appendixes contain forms and other information needed for the digital data entry procedure.
