Full life-cycle vulnerability assessments are identifying the effects of climate change on nongame migratory birds that are of conservation concern and breed in the upper Midwest and Great Lakes region. Full life-cycle analyses are critical, as current efforts likely underestimate the vulnerability of migratory land birds due to a focus on assessing only one component of the annual cycle. The approach provides a framework for integrating exposure to climate changes, sensitivity to these changes, and the potential for adaptation in both winter and summer seasons, and accounts for carry-over effects from one season to another. The results of this work will inform regional management by highlighting both local and...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...

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...

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 main objective of this project was to develop a dataset of large, anthropogenic barriers that are spatially linked to the National Hydrography Dataset Plus Version 1 (NHDPlusV1) for the conterminous U.S. and the high resolution National Hydrography Dataset (NHD) for Alaska (1:63,000 scale) and Hawaii (1:24,000 scale) to facilitate GIS analyses based on the NHDPlusV1/NHD and NID datasets. To meet this objective, Michigan State University conducted a spatial linkage of the point dataset of the 2009 National Inventory of Dams (NID) created by the U.S. Army Corps of Engineers (USACE) to the NHDPlusV1/NHD. The pool of dam data included were modified based on 1) dam removals that occurred after development of the...

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...

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...

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.

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.

Synopsis: This article outlines how wetlands can significantly reduce flooding in the Upper Mississippi watershed. The authors first provide a historical context by estimating the original and lost wetland storage capacities of the Upper Mississippi and Missouri River Basins. Historically, about 10% of the basin would have been classified as wetland in 1780. By 1980, wetland acreage had been reduced to only 4% of the basin, representing about 26 million acres of wetlands eliminated since 1780. The area of wetland restoration required to reduce the risk of future flooding adequately was estimated based on the total amount of excess floodwater beyond bank-full discharge that passed through the City of St. Louis during...

Hydraulic functions of retention devices in natural large rivers have been studied. An evaluation of detention devices formed due to side channels, islands, backwaters, and stump fields within the Upper Mississippi Pools has shown that these are quite significant and in some cases these detention areas within the channel borders can occupy as much as 75 to 93% of the total surface area. A large eddy on the order of the width of the Mississippi River in Pool 19 is used to illustrate the travel time in the hydraulic retention areas.

Synopsis: The purpose of this model is to indicate potential habitat for olive-backed pocket mice (Perohnathus fasciatus) within the Milk River Basin. As this is a landscape level model with course variaqbles, it may not be directly applicable to other areas for site-specific analysis. Conclusions: Olive-backed pocket mice require high proportions of grassland habitat and low proportions of shrub cover. Sites with low densities of shrubs are preferred because they provide cover from large and aerial predators, such as owls. A threshold of below 40% shrub coverage represents ideal shrub cover proportions.
