Tom,
I appreciated your reply though my question was more about whether some additional tools or language has been developed which more richly details and more neutrally expresses ways to understand and communicate around the topic of natives, exotics, invasives. I find this would be an extremely helpful tool for our designs, work, learning and, especially, for our communication with others.
Regarding communication with others, I have in recent years learned about the trivium* method and would like to find ways of applying it to the invasives conversation. This is partly why I am asking you whether you have run across the sort of information mentioned in the first paragraph or are working on creating something like this yourself. As I don't believe much of this has been put together, at least in a publicly accessible form, anything like a summary, notes, index or bibliography would be helpful. But maybe I am realizing that this list that I have been hap-hazardly putting together all along could be of use to change the conversation, and so I have shared a small part of it below.
My interest in this topic is pushed by realizing that going after the non-natives--those arbitrarily-defined species of 'elsewhere'--is not
the answer. It is an illusion and another example of the extension and morphing of the war machine, which is bent on attacking or blaming the other. We do not need to continue the war. One important tool within the trivium method's toolbox with which they suggest one (adult) learn and start practicing is with the logical fallacies. Upon careful examination, some of the reasons given for attacking invasives with chemicals or for implementing other such supporting policies, employ the use of these logical fallacies.
As I find more snippets to learn from, I deepen my fascination and continue to delve into and push outwards this material which is not all that clearly defined nor obvious. I imagine your book on botany sort of provides the trivium for/of botany and plant identification. Moving in the same constructive and positive approach, I endeavor to find and continue building this trivium of invasives, exotics and natives.
What follows in the next paragraphs are examples, as well as a partial index, of what I have found which provide new tools and a richer language to further the multifaceted conversation on, and interaction with, natives, invasives, exotics, weeds, non-natives, invasion biology,... I do not claim the list to be exhaustive nor objective. I provide it here for curiosity and, as always, it is up to oneself to come to terms and check its validity). To let you know, unless otherwise specified, I tend to examine through the lens of plants. Also, if there are no references, the idea may come from Dave Jacke's (and
Eric Toensmeier) book, Edible Forest Gardens.
The first example is about a more specific, descriptive and biogeographical-based system to classify plants which is place-based instead of the simplistic, vague and ambiguos use of “invasive”. The following paragraph is a quote from the article “Refugees Without Legs: How Climate Change Leaves No Room For ‘Invasive Species’”, by Kollibri terre Sonnenblume. (
http://www.carolynbaker.net/2014/01/29/refugees-without-legs-how-climate-change-leaves-no-room-for-invasive-species-by-kollibri-terre-sonnenblume/)
Since then, I discovered that an excellent alternative has been offered: “A neutral terminology to define ‘invasive’ species”, by Robert I. Colautti and Hugh J. MacIsaac, published by the Great Lakes Institute for Environmental Research at the University of Windsor in Ontario [link:
http://onlinelibrary.wiley.com/doi/10.1111/j.1366-9516.2004.00061.x/pdf]. Leave it to Canadians to be more nuanced than their southern neighbors! Colautti and MacIsaac observed that “the use of simple terms to articulate ecological concepts can confuse ideological debates and undermine management efforts” and that “subconscious associations with preconceived terms, particularly emotive ones, can also lead to divergent interpretations and a confusion of concepts and theory”. No kidding! In place of a single word such as “invasive”, Colautti and MacIsaac put forward a system that is biogeographical (place-based) rather then taxonomic (species-based). The system describes possible stages of a new species entering an area. As summarized on Wikipedia, these stages are: I. Traveling, II. Introduced, III. Localized and numerically rare, IVa. Widespread but rare, IVb. Localized but dominant, V. Widespread and dominant. The single Holly tree in the front
yard in Portland was at stage III: “Localized and numerically rare”. Corn in the Midwest, European
trees in New England, and
cattle in Eastern Oregon, by contrast, are at stage V: “Widespread and dominant”. This system can also be used to describe native plants. The conifers being decimated by Bark Beetles are passing from stage V. to stage IVa; from “Widespread and dominant” to “Widespread but rare”, and could soon be at stage III: “Localized and numerically rare”.

Invasion is actually a term used in the science of ecology and is based more on vegetation dynamics (if we are talking plants) or successional change.

On CBC Radio's Ideas program, I came across an episode called “Bioinvasion: Attack of the alien species!”. Some things of interest from this are about the origins and definition of “invasive”. Charles Elton (1950s), is one of the fathers of invasion biology who militarized this term. Although I have not looked at it myself, I found a reference to the “Encyclopedia of Biological Invasions”, a work edited by Daniel Simberloff, who was one of the many people interviewed.

Let us ask more specifics such as during what time period and to what area is a species native?
- - - - - - - - - -
I invite you to examine the work of
David Holmgren (co-originator of
permaculture), especially his topics of novel ecosystems and ecosynthesis, which are very relevant to this shape-shifting kind of discussion on natives. One place to start is his book “Permaculture: Principles and Pathways Beyond Sustainability”. He also has a great article called “Weeds Or Wild Nature”, with several editions so far, which is working itself into a book, maybe to be soon released.

“There currently exists an enormously rich literature of succession ecology that is being virtually ignored by many researchers studying invasions.”

Thanks a lot for donating your book to Permies.com. I got mine today and like the approach or methodology and see that it is a sizeable tome which has had plenty of discipline, thought and focus put into it's creation and constant updating. The work before me is great, but now I feel I can be better prepared with this novel and ingenious way of relating and understanding plants.
I was pleasantly surprised to see the note, dedication to Frank Cook at the beginning of your book. The one thing I knew about him was the article he wrote in the
Permaculture Activist several years back called Listen to the Weeds' Stories. One thing that I liked about this article was the commonality and cosmopolitan nature of weeds, herbs, foods, teas,... which one can find all over the world and which Frank was suggesting we comune with. I can attest to this with my experiences in the Chaco bioregion--mostly in Santiago del Estero, Argentina. There were many plants and herbs which were already known to me, as well as plenty of new ones of which I was able to integrate many plants of that climate new and foreign to me into medicines, teas, foods. This hybrid made it all the more interesting and sometimes made me forget where I really was. I also see and use these plants anew now that I am back in my originary temperate norther climate home. I feel your book works in this same way that Frank's article did, as it shows the relationships, patterns and similarities or features to help in our understanding and use of plants. I now remember that Frank worked extensively with you on your book.
I appreciate your contribution towards a fuller world. Thanks.
Best regards,
Louis
