Jason Rohweder
I have interdisciplinary expertise in biology, geographical information systems (GIS) and application programming. My work emphasizes landscape ecology and the creation of flexible tools and models to assess species habitat.

Changes in aquatic vegetation and floodplain land cover in the Upper Mississippi and Illinois rivers (1989–2000–2010) Changes in aquatic vegetation and floodplain land cover in the Upper Mississippi and Illinois rivers (1989–2000–2010)
Quantifying changes in the cover of river-floodplain systems can provide important insights into the processes that structure these landscapes as well as the potential consequences to the ecosystem services they provide. We examined net changes in 13 different aquatic and floodplain land cover classes using photo interpreted maps of the navigable portions of the Upper Mississippi River...

Relating mesocarnivore relative abundance to anthropogenic land-use with a hierarchical spatial count model Relating mesocarnivore relative abundance to anthropogenic land-use with a hierarchical spatial count model
There is growing need to develop models of spatial patterns in animal abundance, yet comparatively few examples of such models exist. This is especially true in situations where the abundance of one species may inhibit that of another, such as the intensively-farmed landscape of the Prairie Pothole Region (PPR) of the central United States, where waterfowl production is largely...

The Upper Mississippi River floodscape: spatial patterns of flood inundation and associated plant community distributions The Upper Mississippi River floodscape: spatial patterns of flood inundation and associated plant community distributions
Questions How is the distribution of different plant communities associated with patterns of flood inundation across a large floodplain landscape? Location Thirty-eight thousand nine hundred and seventy hectare of floodplain, spanning 320 km of the Upper Mississippi River (UMR). Methods High-resolution elevation data (Lidar) and 30 yr of daily river stage data were integrated to produce...

A case study of assigning conservation value to dispersed habitat units for conservation planning A case study of assigning conservation value to dispersed habitat units for conservation planning
Resource managers are increasingly tasked with developing habitat conservation plans in the face of numerous, sometimes competing, objectives. These plans must often be implemented across dispersed habitat conservation units that may contribute unequally to overall conservation objectives. Using U.S. Fish and Wildlife Service waterfowl production areas (WPA) in western Minnesota as our

Decision support system development at the Upper Midwest Environmental Sciences Center Decision support system development at the Upper Midwest Environmental Sciences Center
A Decision Support System (DSS) can be defined in many ways. The working definition used by the U.S. Geological Survey Upper Midwest Environmental Sciences Center (UMESC) 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 to be, because the possibilities for types of DSSs are limited...

Past and predicted future changes in the land cover of the Upper Mississippi River floodplain, USA Past and predicted future changes in the land cover of the Upper Mississippi River floodplain, USA
This study provides one historical and two alternative future contexts for evaluating land cover modifications within the Upper Mississippi River (UMR) floodplain. Given previously documented changes in land use, river engineering, restoration efforts and hydro-climatic changes within the UMR basin and floodplain, we wanted to know which of these changes are the most important...
