Jason J. Rohweder

Position title: Spatial Applications, Biologist

Email: jrohweder@usgs.gov
Phone: 608.781.6228
Fax: 608.783.6066

Education:
1998 M.S., Resource Analysis, Saint Mary’s University of Minnesota
1995 B.S., Ecology, Winona State University

Primary Responsibilities/Activities:
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. 

Research Interests:

• Evaluating species response to landscape changes
• Regional habitat modeling
• Spatial decision support system development
• Database development and analysis

Active Projects:

• Enhanced Habitat Rehabilitation and Enhancement Project Utilization of Long Term Resource Monitoring Program Data and Resources (LTRMP Team)
• Focusing Regional Bird Modeling on Local Management (Avian Conservation Ecology Team)
• Navigation and Ecosystem Sustainability Program Decision Support System (Geospatial Sciences Team)
• Acadia National Park Landscape-Scale Ecological Assessment for Conservation Planning (Geospatial Sciences Team)
