Research

Oak Lake Field Station provides laboratory and computing facilities and field areas for research studies of northern prairie environments. In addition, the station provides 2-3 seed grants each year to support student and faculty research (see links below). Much of the research activity at the Oak Lake Field Station focuses on ecology, management and environmental issues related to prairie environments. Oak Lake has been the subject of over twenty years of comparative aquatic research. Current efforts focus on the ecological effects of disturbance to littoral zone communities, studies of intermittent prairie stream communities, life-history and human utilization of native prairie forbs, insect-plant interactions and studies of prairie fire and browser effects on vegetation. New efforts are now focused on the influence of management of fields for biofuels production and influence on biological diversity. The station hosts research scientists interested in broader landscape-level questions. These efforts are contributing to greater understanding and sustainable management of natural resources within the Great Plains region.

Monitoring efforts at the Field Station provide data to support instruction and research efforts. Information on station climate and lake monitoring programs can be obtained through the Field Station Director. Climate and lake monitoring data are available for use by state agencies, researchers and educators from this site. In addition, a geographic information system of the Oak Lake watershed has been developed to facilitate instruction, research and management activities on the site. GIS coverage’s are available directly from the field station director.

The station hosts an annual research retreat in October. Students, faculty and visiting researchers are invited to deliver presentations of their efforts and discuss future directions for their projects. A feedback session toward the end of the retreat provides information to field station staff regarding researcher needs and suitability of facilities.

Oak Lake Field Station administers three competitively awarded grants to support faculty and undergraduate research. These grant funds are intended to help support initial research efforts. These grants support efforts extending over one calendar year and must be conducted at the station. Faculty or students interested in applying for one of the incentives grants should explore the hyperlinks below to gain access to forms and deadlines.
