Message-ID: <200204051920.g35JKQ262782@pilot07.cl.msu.edu> Hello KNBers- I'm sitting down to classify the KBS LTER plants as native, non-native, and invasive, and realizing it's not as clear cut as it first seems. I'm trying to follow the protocol on the course website using the USDA PLANTS database to look up individual species and their classifications as invasive or noxious, but as Jim Grace pointed out, these lists are not very complete. Plant status in Michigan is not listed at all. So I was using the USDA Invaders lists for Michigan, but this lists only agriculturally important weeds, and misses some big ones like garlic mustard or multiflora rose. There is no "definitive" list of invasives in Michigan that I can find, though lots of lists with varying definitions of "invasiveness" have been created. My question is: do we want a standard way of classification based on the USDA PLANTS database? If so, if a plant is listed as invasive in one part of the country (for example, St. Johns Wort in the West), should we in Michigan also consider it invasive, though it is rarely, if ever, a problem and often considered simply "non-native but established"? How "invasive" does a plant need to be to be considered "invasive" instead of non-native in our classifications? Should "invasive" apply only to our top 5-10 nasty species? If no one has any suggestions, my plan is to use a conglomeration of several lists focusing on invasive status in the midwest...which is kind of subjective and not very standardized, but which best reflects the situation here. Okay, sorry for the long note. Feeback either to me or the list would be greatly appreciated!

I guess my only hesitation with using many lists is that it is so subjective, even though it might end up being what we have to do. I do agree, though, that using the USDA list doesn't seem to be the way to go. Do any one of the other lists work pretty well for your sites? If so, perhaps you could use the best of the lists so that it is objective, and yet also best serves our needs? Is that possible? What are the other sources of data?

It can be found at http://www.fs.fed.us/r9/weed/Sec3B.htm if anyone wants to check it out. THis way, we're using just one list (a couple of people had concerns about combining several lists). This solves the immediate problem I think, but reinforces the difficulty of defining "invasive" species...perhaps something we should discuss in May. Thanks to the people who provided input... -Sarah -- ************************* Sarah Emery Graduate Student Kellogg Biological Station Michigan State University 3700 E. Gull Lake Rd.

The KNB development team released new versions of Morpho and Metacat this week. The new version of Morpho (Morpho 1.1.0) is available to download from the website. Please install it the next time you use Morpho. The new version contains many more bug fixes as well as some new functionality that will increase its? usability! This release also provides the capability for us to utilize access permission groups. We have created a ?knb-usr? group, which will allow our course data packages to be available to all KNB students and faculty via Morpho while restricting access to other users. The data czar(ina)s will be receiving instructions on how to enable the ?knb-usr? group for each course's data packages shortly. PLEASE NOTE: If, the next time you use Morpho, you are not able to find the data packages this means you are not part of the ?knb-usr? group. Please send us your user id and we will add you to the group. Similarly, if you have NEVER gone through the web forms and created a Morpho / Metacat user id, you will need to send us your user id to get added to the new group. Please let me know if you would like more information, have questions, etc. Eric From berkley at nceas.ucsb.edu Wed Apr 24 12:06:52 2002 From: berkley at nceas.ucsb.edu (chad berkley) Date: Wed, 24 Apr 2002 12:06:52 -0700 Subject: [Knb-course] Power Outage Message-ID: <3CC7024C.1060403@nceas.ucsb.edu> Hello KNB Course participants, NCEAS will experience a power outage this weekend.
