Ethan Bucholz

Ethan Bucholz is the Academic Liaison and Experiential Learning Specialist for the Colorado State Forest Service and the Forest and Rangeland Stewardship Department, CSU. His research interests include understanding how to best augment our management to meet the challenges of climate change, invasive pest biology, and the intersection of silviculture and ecology. He collaborates with land managers and stakeholder groups in implementing and designing innovative treatments that accomplish a litany of ecological goals, thereby helping increase forest resilience to climatic and biotic changes. His education and professional experience have helped provide the context for the forest health triangle, and he hopes to continue working towards healthy Colorado forests.

Seth Ex

Assistant professor of silviculture. Originally from the Upper Peninsula of Michigan (hardwood country!), I started working in natural resources and forestry in the 2000's in bark beetle-affected Lutz spruce forests in Alaska's Kenai Peninsula. I relocated to the interior West in 2007 and have been working and playing among the diversity of forests in this region ever since. My primary focus is on professional instruction in silviculture and forest management disciplines. I draw significantly on my academic background in applied ecology and quantitative silviculture in my teaching. Ultimately, my goal is to facilitate student growth by providing engaging, relevant course content that is accessible to a diverse suite of learners.

In Alaska, Casey’s program responsibilities span the spectrum from livestock and range to soils and horticulture. He is a primary investigator and collaborator on a number of research and outreach projects investigating: forage production, soil health, integrated pest management, and produce safety. Prior to his position in Alaska, Casey was a Rangeland Extension Specialist in Colorado for five years. Casey has been instructing college courses in rangeland management since 2006. In 2010, he received a Ph.D. from Oregon State University for his research studying winterfat and grazing ecology in the Catlow Valley of Oregon.

Wilfred Previant

Wilfred Previant is an Assistant Professor of Forestry in the Forest and Rangeland Stewardship Department at CSU, where he teaches courses in forest management and measurements. His research includes forest inventory and analysis, monitoring, adaptive forest management, silviculture, and carbon management. Wilfred received his PhD in Forest Science from Michigan Technological University.

Robin Rothfeder

Robin Rothfeder is an Assistant Professor of Natural Resource Policy in the Forest and Rangeland Stewardship Department at CSU. Robin's classes use social-ecological challenges and opportunities as the focal point for engaged, interactive learning experiences. His teaching in the MNRS program focuses on environmental impact analysis as governed by the National Environmental Policy Act (NEPA). His research covers two broad topics: (a) collaboration in social-ecological systems, and (b) water resource planning, policy, and management. In both areas, he takes an interdisciplinary and mixed methods approach aimed at meeting real-world community needs.

Robin has a diverse interdisciplinary background, including undergraduate degrees in Environmental Science and Environmental Economics from the University of California-Berkeley, as well as a master’s degree in Environmental Humanities and a PhD in Ecological Planning from the University of Utah.

Jeremy Sueltenfuss

Jeremy Sueltenfuss is an Assistant Professor of Ecology in the Forest and Rangeland Stewardship Department at CSU. He is generally interested in the ecological impacts humans have on the natural world, and how to effectively restore ecological integrity and ecosystem functions. He collaborates with local, state, and federal agencies on wetland and floodplain restoration projects, although his interests in increasing the efficacy of ecological restoration encompass all ecosystem types. He holds a PhD in Ecology from Colorado State University.
