Penstemon acaulis

Dear members,

Over the last couple of years I have spent some time developing models of the geographic distribution of Penstemon acaulis. The probabilistic models generate probability surfaces of the region studied showing for each cell a probability from very low to very high of finding the species. To this end I have also spent time in the field (WY and UT), each year, collecting gps data points of the location of various populations of P. acaulis and have the coordinates of several thousand plants. I have submitted vouchers for new populations to the Rocky Mountain Herbarium. My plan is to make a final model, the predictions from which will be field-verified in May-June 2011. The hope is that the model will describe the geographic extent of the distribution of this species.

For this final run of the model I am looking for additional data points, which members may have collected with or without gps that might provide additional information on the range of the species. Any geographic description of areas where plants of P.acaulis have been personally sighted would be very welcome. I can be contacted directly via email with details at: jouse001@umn.edu

I apologize to members who might get duplicate messages; I am posting on Alpine-L, the Penstemon list, as well as the NARGS forum.

Thank you for your help.

I will send data for a few populations outside of Manila on the Wyoming side.  Any interest in P. yampaensis which some consider a variety of P. acaulis?  My reply will be by email rather than forum.  A good many of us in NARGS are also members of APS so you have probably contacted most members who I know may have data points.

Hugh, many thanks; I look forward to receiving your data. Yes, I would be interested in P. yampaensis as I have been toying with the idea of doing a model for that species (?) or var(?) let's say taxon. Last Spring I discovered that taxon in Wyoming as well; apparently the first record for that state.

Happy New Year.
