"I can't praise Dr. Shaw (and Salix) enough.  For the past three years, she has consulted on our NSF-funded project, analyzing charcoal samples from a massive Northwest Coast archaeological site. Besides plant identification, she helped guide our selection of annual/short-lived plants for AMS dating. All along the way, I've been greatly impressed with her rigorous, meticulous, and thoughtful approach-- to scheduling, research design, and reporting. She's amazing, really."

"Jennie has always provided us with prompt, accurate, and professional charcoal identification results. She tailors her work to our particular research needs and pays attention to our scheduling constraints in a way that keeps our projects on time and on budget."

"Dr. Deo Shaw provides top notch charcoal identification. She has been a great resource for our Tse-whit-zen NSF project, identifying short lived plant species from charcoal samples. Her selections have helped us produce high precision radiocarbon dates and minimized issues resulting from "old wood." She provides a professional report in a timely manner, with thoughtfully reasoned recommendations. Highly recommended!"

     - Sarah Sterling, Asst. Professor of Anthropology, Portland State University

"Thanks so much, Jennie, for helping us avoid the "old wood" problem, and selecting appropriate charcoal for radiocarbon dating."

"Salix Archaeological Services analyzed charcoal samples I was considering for radiocarbon dating. Shaw provided details on sample quality and identified each specimen in an excellent report. I appreciated the speed and professionalism of Salix Archaeological Services and will be using the company again for future paleobotanical needs."

“Dr. Jennie Deo Shaw (Salix Archaeological Services LLC) provides superb service in the area of charcoal recovery and analysis. She has become an important and integral part of our project investigating a deep Middle Paleolithic site in Montenegro. Her work has involved everything from the assembling of the first comparative collection of wood charcoal from this part of the world to designing the sampling strategies and methods for this complex site. It is important to stress that Dr. Shaw does not simply provide identification services, but is a serious and highly competent scientist who can consult and advise on all aspects of research design and methodology in the area of archaeobotany.”
