The book, The Redwoods (published in 1969 by Popular Library), by Kramer Adams, is cited by Gregory Jones in his Masters Theses, Coast redwood fire history and land use in the Santa Cruz Mountains, California (2014, San Jose State University).
It looks like a fairly rare book with only a handful of copies showing up in my online searches.
