As a professor in the Division of Forestry at Paul Smith's College, he has written three books on the flora of the Adirondacks, including Adirondack Upland Flora, as well as a vast number of articles on forest history of both the Catskills and Adirondacks.[2][3][4] As a railroad historian, he wrote Where Did The Tracks Go?, an initial description of railroads in the Adirondacks, followed by Railroads of the Adirondacks, for a long time considered the definitive work on the subject.[5][6] He has since retired from Paul Smith's College, moved to the Catskills, and has completed a four-volume set on the Mountain Railroads of New York State. It updates Railroads of the Adirondacks in the first three volumes, and adds a fourth volume covering the Catskills (with a separate Addendum volume of 55 pages).[7][8][9][10][11]
The Michael Kudish Natural History Preserve in Stamford, New York is named for him.
