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.
