TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool, to provide guidance for ecological monitoring programs when resources are not...

Database and web application for invasive carp catch data (Illinois River Catch Database)

Four types of invasive carp are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional...

Upper Mississippi River System Weighted Wind Fetch Analysis (1989, 2000, 2010/2011)

Wind fetch is defined as the unobstructed distance that wind can travel over water in a constant direction. Fetch is an important characteristic of open water because longer fetch can result in larger wind-generated waves. The larger waves, in turn, can increase shoreline erosion and sediment re-suspension. Wind fetches were calculated using the wind fetch model available from (...

Decision-support tool for managing endangered species in the face of uncertainty

Along the Santa Clara River in California, populations of the federally and state-listed Least Bell's Vireo (Vireo bellii pusillus) are recovering from near extirpation. Habitat protection and restoration, as well as reducing brood parasitism by Brown-headed Cowbirds (...

Modelling and mapping vegetation change at Isle Royale National Park, USA in response to wolf restoration and climate change.

Isle Royale National Park’s populations of wolves and moose are world renown as the subjects of the world’s longest running predator/prey study. However, inbreeding depression among wolves began to take its toll in the early 2000’s, reducing the wolf population to just a lone pair by 2017. Following a multi-year environmental impact assessment, the National Park Service began re-introducing...

Forest Canopy Gap Dynamics: Quantifying Forest Gaps and Understanding Gap-level Forest Regeneration

Floodplain forest is a major and critical component of the Upper Mississippi River System (UMRS). The current and future condition of floodplain forest on the UMRS is receiving increased attention from managers as the forest appears to be declining and not regenerating. A primary concern is invasive reed canarygrass (Phalaris arundinacea), Dutch elm disease (Ophiostoma ulmi...

Consequences of forest connectivity from beech bark disease in Pictured Rocks National Lakeshore in the Upper Peninsula of Michigan

In this study, we are working with Pictured Rocks National Lakeshore (PIRO, or Park) in the Upper Peninsula of Michigan (Figure 1) to produce multiple geospatial layers of Park forest connectivity to reveal the effects of beech bark disease (BBD). There has been a 92% mortality rate of American beech (Fagus grandifolia) since BBD was first discovered in the Park in 2001. Park...

Decision Support Systems

A Decision Support System (DSS) can be defined in many ways. The working definition the Upper Midwest Environmental Sciences Center (UMESC) uses is, "A spatially based computer application or data that assists a researcher or manager in making decisions." This is quite a broad definition and it needs...

Submersed Aquatic Vegetation Modeling Output Online

The ability to predict the distribution of submersed aquatic vegetation in the Upper Mississippi River on the basis of physical or chemical variables is useful to resource managers. Wildlife managers have a keen interest in advanced estimates of food quantity such as American wildcelery (Vallisneria americana) population status to give out more informed advisories to hunters before the fall...
