NEW BOOK Available here: Comparative Anatomy of Branches, Roots and Wood of Some North American Dicotyledonous and Coniferous Trees and Woody Shrubs Used in Ethnographic Artifacts : Identification and Conservation Concerns

by Mary-Lou E. Florian

Mary-Lou Florian,  Emerita Conservation Scientist, Royal British Columbia Museum, Victoria, B.C. Canada, has generous provided us a link to the chapter’s of her important and well illustrated new contribution: her lifetime work on plant identification with a study of comparative anatomy and conservation concerns for wet/wetland site and ethnographic wood and fiber artifacts.

The book deals with the comparative anatomy of the tissues of the bark, phloem, heartwood, sapwood, and pith in wood, branches, and roots of woody shrubs, hardwood trees and softwood coniferous trees, that were reported to be used historically in making ethnographic and archaeological artifacts. The species researched in this book are endemic to Northwest Coast of North America. The species used in the following chapters have anatomical characteristics that are also common in other genera in the same family. Even though the book is on species in the NW Coast of Canada , the information is applicable to tree genera in similar latitudinal environments in Canada, USA, Europe and Asia.

I am pleased we can almost immediately provide this new release to NewsWARP researchers throughout the world and make sure Mary-Lou’s monumental work can be used to assist with plant identification and conservation work that is so important and fundamental to wet/wetland artifact research.

You can download chapters of the entire book at this web site:  Comparative Anatomy of Branches, Roots, and Wood….

WARP30 Abstract/PowerPoint: Getting Out of the ‘Glutinous Ghetto': The Acknowledgement of the Lake-Dwelling Myth

Pioneers of the progress of civilisation

Since 2011, the Prehistoric Pile dwellings around the Alps have been listed in the UNESCO World Heritage. This reflects the importance of the study of these sites, both in the shaping of the methods of prehistoric science, and for the understanding of habitat, economy, craft and everyday life during the recent prehistory of Europe.

On further examination, one may wonder however about the reasons for the very late integration of this field of research into mainstream archaeology. For a decade now, specialists of the field have identified several motives for this poor recognition, which Francis Pryor qualifies as a “glutinous ghetto” noxious to the dialogue within the discipline. These motives may be summarized in a few keywords: a strong methodological specialization detrimental to the widening of synchronic, cultural perspectives, approaches governed by functionalism, and explanatory schemes favouring environmental determinism.

Our contribution will show that in this matter, the burden of the history of research should also be taken into account. In fact, the development of lake-dwelling archaeology is closely related to its double, national and ideological instrumentalization. On the one hand, the discovery of the lake-dwellings has indeed contributed to the affirmation of the national identity of the new Swiss federal state founded in 1848 in the aftermath of the Sonderbund civil war. On the other hand, and in a more subtle way, what we define as the “lake-dwelling myth” has long served to promote the universal values of liberal progressivism. [see illustration above]

Accordingly, the “Lake-Dwellers” were mobilized in the fight against Pangermanism and Nazism – an embarrassing legacy for modern archaeological science. Until the end of the twentieth century, the archaeological community actually strived to refrain from all social and cultural interpretations, which might be suspected of ideological exploitation.

In this sense, the application to World Heritage which started in 2004 heralds the start of a new era in pile-dwelling research, fostered by a new generation of prehistorians, who take advantage of a renewed, critical and reflexive historiography in order to dispassionately address this potentially sensitive past.

WARP30–the 30th Anniversary of the International Wetland Archaeological Research Project (WARP) A Great Success!!!!

From June 28th through July 2nd, 2016 Drs. Francesco Menotti and Ben Jennings hosted the 30th Anniversary of WARP at the University of Bradford, England.  We had three days of great presentation exchanges by the delegates from all over the world.  Bryony Coles, co-founder of WARP with husband John Coles, lead off with a history of WARP and Dale Croes showed how it spread throughout the world to create a much needed exchange among wetland/wet site archaeologists.  We are posting the PDF of the entire conference here for everyone to appreciate:  WARP30 entire program and abstracts of presenters June 28th–July 2nd, 2016, Bradford, England.

Also in NewsWARP we hope to publish as many of the papers and PowerPoint presentations as PDF, leading off with a great example by  Urs Leuzinger, Department of Archaeology Thurgau (Frauenfeld, Switzerland) and his paper, in English and Swiss (we publish in all languages in NewsWARP) and his PowerPoint PDF:   The Wooden Stone Age – a Paradise for Experimental Archaeologists — please view under the Reports Category in NewsWARP: Urs Leuzinger’s WARP30 Paper/PowerPt.  We hope many other attendees will share their paper/powerpoint PDFs so that this exceptional collection of WARP30 presentations can rapidly be enjoyed and appreciated by all.

Please send other submission to Dale Croes at .  A GREAT THANKS to Francesco and Ben for making our 30th a great time together–that WARP has succeeded for 30 years is a real tribute to our wetland/wet site learning community.  We all agreed at the ending session that we need to keep promoting our area of specialty into the archaeological community and WARP now has taken this lead for 30 years!  Thanks

WARP30 Paper/PowerPoint: The Wooden Stone Age — A Paradise for Experimental Archaeologists

We hope to publish papers and PowerPoints given at the recent 30th Anniversary of WARP Conference, held June 28th — July 2nd, 2016 at the University of Bradford, England.  Urs Leuzinger provided me his Flash Drive at the conference with his Paper, both in Swiss and English (we publish in NewsWARP in all languages) and a PowerPoint PDF.  Here is part of his Abstract, and the whole thing can be seen in the WARP30 program catalog under the Conference menu category in NewsWARP.

The Wooden Stone Age–A Paradise for Experimental Archaeologists  by Urs Leuzinger, Department of Archaeology Thurgau (Frauenfeld, Switzerland)

Thanks to the excellent preservation conditions that prevailed in the waterlogged layers of the prehistoric wetland settlements around the Alps precise information is available on the architecture and implements that would not normally have survived the past millennia. Wooden objects in particular, but also textiles and botanical remains, complement the usual artefact categories of stone, pottery and metal. This lecture presents a selection of features and finds from pile-dwelling settlements that allow today’s craftspeople to create replicas.
