Providing a Historical Context for Oak Ecosystem Restoration in the Midwest
Driftless Area

 

Active management is being undertaken to restore native ecosystems in the Midwest Driftless Area, but largely without attention to historical vegetation and disturbance dynamics in the region. We inform restoration practice by providing insights into the historic role of land use and fire within these ecosystems.

Forest Change in the Midwest:  The Impact of Stakeholder Perceptions and
Management Actions on the Fate of Our Oak Forests

 

The causes and consequences of forest change are often found to be associated with complex and dynamic ecological and social factors.  In many Midwestern forests, forest composition has changed with a decrease in oak dominance.  A changing forest composition can impact the region both ecologically and economically.  In this research project we are evaluating the implications of forest change in the Driftless Area of the Midwest and potential future conditions given various ecological and social threats.  To better understand social factors that can shape future forest conditions, we incorporate stakeholder driven management prescriptions in our modeling efforts.

Establishing Restoration Baselines for the Loess Hills Region
Contact person: Dustin Farnsworth or Lisa Schulte
  Lack of fire and grazing has allowed widespread invasion of woody and non-woody species within the regionally biodiverse and globally rare Loess Hills ecoregion. We expect to inform the restoration and management of grassland and savanna habitats in the Loess Hills by assessing departure from reference conditions.

The Perennialization Project: Perennials as a Pathway to Sustainable Agricultural Landscapes in the Upper Midwestern U.S.
  In the Midwest, ecosystems dominated by forests, woodlands, savannas, prairies, and a variety of wetlands have been transformed into landscapes dominated by agriculture.  This unparalleled land conversion has degraded aquatic resources and restricted native plant and animal communities to small and often isolated remnants.  This research assesses the effectiveness of strategic restoration or perennial land cover in improving both the social and ecological function of Corn Belt ecosystems.

Deep Roots: Analyzing Restoration of Perennial Vegetation and Resilience of Linked Social-Ecological Systems in U.S. Corn Belt Agricultural Landscapes
 

As the Corn Belt enters a time of fast-paced and uncertain land-use change driven by the demands of the emerging bio-economy, regional landscape change will take place, impacting the resilience of rural social and ecological systems for years to come. In this project, we work with rural stakeholders to examine the dynamic and interlinked social, ecological, and economic variables underlying agricultural land use change.

Healthy Agricultural Landscapes for Resilient Rural Communities: Participatory Watershed Design to Bridge Gaps among Science, People and Policy
  PEWI is an interactive and integrative model for stakeholder assessments in predominantly agricultural regions at the watershed scale. Users iteratively manipulate watershed conditions, e.g., type and location of various land covers and land uses, to design systems that meet their perceptions and goals for a well-functioning agricultural watershed. The model computes a diverse set of outputs that are designed to reflect farm resilience, community resilience and ecological resilience.

The Impact of Federal Farm Policy Eras on the Rural Landscapes of Iowa :
A Seventy-Year Retrospective Assessment and Implications for the Future

  As Midwestern agriculture charts a new course in a new century, policy initiatives must consider historical outcomes of previous policies, current socioeconomic and environmental issues, and a future-focused vision related to agricultural and rural sustainability.  To inform policy development, this project examines how federal farm policies have affected rural Iowa landscapes over the past 70 years and determines what federal farm policy initiatives rural Iowans will accept in the future.

Avian Response to Restoration Silviculture: Overstory Retention in Red Pine Ecosystems

 

Contemporary harvesting practices frequently result in simplification of structure and composition in managed forest stands in comparison to their natural counterparts. Loss of heterogeneity within stands may pose a problem for maintaining of biodiversity in perpetuity. In this research project we are assessing forest bird response to alternative forest management practices within red pine ecosystems by determining which elements of heterogeneity are important and whether some harvesting scenarios provide more beneficial habitat than others.

Forest Dynamics in mesic northern hardwoods following windthrow and salvage logging in the Flambeau River Hemlock-Hardwood Scientific Area (Wisconsin)
  High severity winds are a natural phenomenon that can cause broad-scale catastrophic disturbances in forested systems. Catastrophic windthrows change not only the canopy structure through the removal of dominant trees, but also the soil and moisture conditions, tree recruitment patterns, and understory vegetation growth related to microtopography conditions. Forest recovery after catastrophic windthrow is less commonly studied than the effects of damage itself. Understanding the effects of catastrophic wind events on forest systems is important not only for informing current forest management practices, but also because the frequency of such storms may increase in the future.
