Land-water interactions in North Temperate LandscapesContactsKeywordsriparian, wetlands, watershed, shoreline development, terrestrial-aquatic interactions, long-term ecological research (LTER), eutrophication, carbon cycling, land-use change Research OverviewLakes and rivers are important features of the landscape of northern and southern Wisconsin. In collaboration with faculty and students at the Center for Limnology, our lab has focused on the landscape setting surrounding fresh water ecosystems and on the interactions between the terrestrial and aquatic ecosystems. In addition, our research contributes to understanding linked social-ecological systems. We currently are involved in two ongoing projects:

Terrestrial ecologists have made great strides in understanding the geophysical template, climate, disturbance regimes, and vegetation dynamics that control groundwater, surface water, carbon and nutrient fluxes in the Northern Highlands and other landscapes. Despite these advances, there are considerable gaps in understanding the magnitude and spatial patterns of biogeochemical fluxes. For example, terrestrial ecologists have found important imbalances in the carbon cycle. These gaps may be closed by studies that consider the complete landscape – that is, the integrated behavior of terrestrial upland vegetation, wetlands and surface waters. The goal of our project is to understand how the extent of surface water and wetlands affects ecosystem production, respiration, and spatial flow of organic carbon on complex, heterogeneous landscapes. The approach centers on simulation modeling of hydrology and biogeochemistry, with ground-truthing and calibration data provided by field measurements. We focus on the Northern Highland Lake District (NHLD) of northern Wisconsin and Upper Michigan, a complex landscape with over 7500 lakes and diverse forested and wetland ecosystems. Our research team has developed a new integrated spatial simulation model for hydrology and carbon cycling of the entire NHLD (Cardille et al. 2007), and early results are summarized here. Ongoing work on the project includes the testing of climate scenarios using the simulation model, as well as the development of a full regional carbon budget for this lake-rich landscape.
