Hi David:
Here is some background to the camas project we recently talked about. I am copying Susan Kephart and Matt James on this as I am hoping we can coordinate this project in some ways with their academic studies.
It might be good to consider a meeting in Salem or Corvallis sometime in the next few weeks or months to discuss short-term objectives and long-term strategies. 
Thanks for the Kramers thesis and the Gorman papers — all very helpful! 
Bob

Hi all
Matt. glad you hear of your studies... I"m finishing up intensive field work on camas in pretty remote areas of N California at the moment (I'm at WIllamette University and have worked most in OR pops... I''m on a deadline to get home today and have one more population to sample.. but will try to get back to you soon on what I know. We've been gathering morphological, genetic, ecological and other data in the field on populations throughout the west and more recently also in the eastern part of the distribution as part of NSF funded grant in systematics. As part of that field work, I've also noted whether some of those sites occur on or off "reservations".. but camas cultivation, tending occurred in "natural" meadows as well .. I'm not an ethnographic expert of course.. but try to be aware of this in what we are doing
There is lots more I can share but we're in the midst of intensive field season as plants flowered a bit off schedule here and in other places we're traveling as a team. I will try to get back to you with more detail either before or after I get back to town.
You might have already seen published maps in Gould's 1942 monograph and Flora N america (On line.. Ranker and Hogan.. efloras).. etc.  We are working on extending maps with GIS data for pops we've studied (and ground truthed) and we've been data basing records from other sources as well. Perhaps we can talk sometime .. might be more efficient.  Nancy Turner's students have published extensively on camas in relation to ethnobotany including thesis by Brenda Beckworth (sp).
In next email I'll attach a few of pubs funded in part thru grants to my lab. We have another methods paper coming out this year.  Glad to see your approach.. it would be great to have a more detailed analysis linking the archaeological, botanical work to fire and aboriginal practices..  THere are some papers as well describing response of camas to fire in managed ecosystems . not many but some that I've seen..
Also..we've dones some seed germination studies in response to temperature in camas as have others.. Let me know if interest.
Susan

Tom Connolly with OSMA at U of O has done the best archaeological research in Oregon (my opinion) and probably has the best grasp of the archaeological literature in Oregon as an active field researcher. CC'd him with this reply as well.

Hi Matt:
I'm copying Frank Lake on this, another OSU grad, in addition to Le and Bill. Frank will have a better idea on camas seed viability in regards to heat than I will -- just be aware that camas isn't fire-dependent, can go dormant for decades, has a very hard ("insulated") shell, and that duration of heat during a prairie burn would be fairly ephemeral.
http://www.orww.org/Bald_Hill_2004/Native_Plants_Tour/Video/Burn_Results.mpg
Camas was harvested with sticks and transported in baskets, so if you mean "lithics" by "archaeological sites," the best chance of that would be processing areas -- I'd start with the Calapooia Mounds in that regard. Camas was everywhere; camas ovens more localized.
http://www.orww.org/Kalapuya-Amin_2006/Program/RouletteB/Baby_Pyramids_20060908.html
Something that I think would be useful (and why I'm continuing to copy the others), would be to study the effect of disturbance (digging and replanting) on camas reproduction:
http://www.orww.org/Bald_Hill_2004/Native_Plants_Tour/Video/Camas_Bulbs.mpg
Finally, if you want to use GIS (and here's where you might get different opinions from others), I'd suggest plotting as many of the remaining camas patches as you can (there are still quite a few on OSU Forests and Ag Lands, if that is a scale you want to use) and correlate those to human disturbance history. Le or Frank probably have a better idea, but I think maybe the Native Plant Society might be a good starting point for the information you are looking for. I've also attached Kat Anderson's latest on the topic (her email address is included), but I couldn't find a publication date. I think maybe earlier this year. Kat would also be an ideal person to contact directly in regards to setting up an experiment along the lines you're discussing.
I'd highly recommend the MAIS for PhD work in the fields you've listed -- and especially keep crop science in the mix! And you might want to look to NRCS for possible funding assistance.
Good luck!
Bob

It's good to talk to someone from the MAIS program!  I have really enjoyed the program so far, and have developed a passion for ethnobiology- specifically as it pertains to aboriginal ecosystem management practices.  In the future, I hope to pursue a PhD, but am a little torn between ethnobotany and ecology.

 I think I may have worded my original inquiry poorly- I was looking for a map of Camas locations that I could use as an overlay to archaeological sites.  But you bring up some important points- particularly that of the timing of traditional camas harvest vs. timing of fires.  I will be looking at that next.  As a scientist who works with fire ecology, do you have any information as to temperature gradients in soils during a low-fuel broadcast burn?  I read a study in which scientists tested seeds of various plants at temperatures ranging from 40 degrees C to 120 degrees C at 5 degree increments.  While this may give a better sample range, I don't think I could come up with the 10,000+ seeds that it would take to replicate the experiment with Camas!  Here's what I think, and I would love your input on this: Soil surface temperatures in hot, direct sunlight could reach 40*C so I don't think that temperatures lower than this would provide much fire-relevant data.  On the other side, the lethal temperature threshold for most seeds is around 60*C.  Do you think I should keep my temperatures within that 40* to 60* range for this experiment, or should I go higher to accommodate for some extreme, previously unknown resilience within Camas seeds?  I'd love your input.

Hi Matt:
First, I'm glad you're in crop science -- the forestry and wildlife people don't seem to grasp these concepts when it comes to "wildlife habitat" theory. 
1) Camas populations do not "over lap" Indian lands -- they are at the heart of those lands. Think New England apple orchards or Irish potato fields. Camas does not readily spread on its own and its range has become increasingly restricted during the past 400 years (about 200 years in Oregon). Finding a camas patch is like finding a stash of arrowheads when it comes to interpreting pre-white native cultures. This isn't "foraging," it's crop management.
2) Most camas harvest seems to have been done in spring and early summer, as Le suggests, but could be done almost any time of the year. Broadcast burning in the Willamette Valley seems to have started in July some years and peaked in August for harvesting tarweed. Fall burns are more associated with hunting and filbert and acorn harvesting.
3) Camas production is more related to tillage than to fire. Areas that were harvested during a year would have been mostly bare dirt and wouldn't have carried much -- if any -- flame. The seeds are heavy and drop to the ground. A broadcast burn in low fuel loads, such as grasses and tar weed, burns quickly and often barely heats up the surface soil. Seeds and sprouts can usually survive such a burn with no problem. Perhaps the warmth of the fire had a positive influence on seed germination (semi-serotinous).
4) I'm pleased to see you use Le's term "pyroculture." I did the same thing during my grad studies at OSU.
Hope this helps!

I have been in Italy so just getting back to your question.
I do not know of any definitive map or GIS (hard data) research on burning and camas production. There is evidence for burning as a management tool. Burning is situational more than absolute. The sum of multiple burns for a variety of reasons on climax vegetation and vegetation that benefits from burns has been partially modeled in some published sources. I do not recall any study on burning and camas seed germination. The production of camas seed and its natural distribution, in my experience with local fields at the State fairgrounds, occurs early in the season and prior to likely native burning time tables. 
I suggest you contact Bob Zybach or Bill Woods (both cc'd here)They may be your best source for the data you are looking for and can comment on seasonal timing.

Dr. Gilsen,

My name is Matt James and I am an interdisciplinary grad student at Oregon State University where I am studying crop science, international agricultural development, and rural studies.  For my thesis, I am exploring physiological reactions of camas (Camassia Quamash and C. Leicthlinii) to aboriginal fire regimes in the Willamette Valley.  As you know, a substantial historical record exists of PNW First Peoples using fire as a management tool to, among other things, improve Camas populations.

The literature, however, lacks a clear exploration of fire's effects on seed germination and dormancy, which is what I am hoping to contribute.  I was reading your Pyroculture article and was curious if you have any GIS data or other maps showing how Camas populations overlap traditional First Peoples lands?  If so, would you be willing to share?  I am trying to get a better idea of the extent of fire use and traditional foraging grounds so I can better round out my ethnobotanical research.
