I came across a book recently, Beyond the War on Invasive Species: A Permaculture Approach to Ecosystem Restoration, by Tao Orion with a foreword by David Holmgren.
I haven't read it yet, but this is from the Library Journal: "Here is a brilliant, alternative way of dealing with nonnative, invasive species. Oregon State University permaculturist Orion’s emphasis is on plants, and her survey of relevant literature is a virtuoso incorporation of books, journals, electronic resources, and personal communications, written in commendable expository prose. In the face of overwhelming political correctness, which dictates that invasive species should be eliminated, the author offers ways to exploit and adapt to them in addition to extolling the virtues some of the species exhibit. As an instructor, Orion teaches ways to manage ecosystems with an eye to long-term results, free of herbicides and destructive attempts to remove species seen as undesirable. She pays special attention to the behaviors of ‘primitive' societies in relation to their surroundings. In her view, pre-Columbian America was already far from pristine; it underwent many changes wrought by Native Americans, especially through fire. This thoughtful, controversial, and well-documented book is guaranteed to infuriate many and to provoke us into rethinking our attitudes about what is natural and best for the land. With essays such as 'The Myth of Wilderness,' the reader is challenged to confront revolutionary ideas about our landscapes."
I, too, have a problem with invasives on my land, but am interested in doing more than just trying to get rid of them. Why are they there? Can I discourage them? Can I use them?
