Dean Apostol, MIG

Environmental Consultant, Portland, OR

Mr. Apostol is a semi-retired environmental consultant, restoration ecologist, teacher, and writer. He graduated from Iowa State University in landscape architecture in 1977. Mr. Apostol credits Professor Robert Dyas, a noted lover of the Midwestern tallgrass prairie (and World War 2 vet), with sparking his interest in native ecosystems and how to use them in landscape design and planning. He has had a 40 year career based in the Pacific Northwest and California.  Mr. Apostol was a licensed landscape architect in Oregon from 1983-2015. His career has included private and public practice. Mr. Apostol practiced independently for 15 years, spent 11 years with the US Forest Service, 6 years with MIG’s Portland office, and has worked with AECOM recently as a Senior Visual Resource Specialist.  At the Forest Service he collaborated with ecologist Nancy Molina on development of a process for applying landscape ecology to forest management. This was published as  “Forest Landscape Analysis and Design,” and led to consultation and teaching on applying its ideas around the US, Canada, and in Europe. 
A long interest in the restoration of natural ecosystems led Mr. Apostol to write and edit “Restoring the Pacific Northwest,” published by Island Press in 2006. This book provides a broad geographic overview of regional ecosystems and the state of the art for restoring them to health. He followed this with publication of “Designing Sustainable Forest Landscapes” (Taylor and Francis Press), Another area of interest is conservation of scenic landscapes, and in 2016 Mr. Apostol led a team to research and write “The Renewable Energy Landscape” (Routledge Press).    This book looks at the impacts on the visual landscape of large scale commercial energy project, particularly wind and solar. In semi retirement, he continues to consult, teach, and write. Mr. Apostol’s teaching has included  adjunct terms at Portland State, Oregon State, and University of Oregon, where he currently teaches Applied Ecology for Landscape Architects.
