Oy, my third month here at the CO state office has come and gone. So what have I been up to? May has been full of Penstemon grahamii, Physaria congesta, and preparing for the CLM training in Chicago.

First, Penstemon grahamii. I talked about this species in my first post, and we have finally been out for monitoring. And we got to see it in flower! The actual monitoring was easy enough. This plot and the monitoring protocols have been established since 2005, so it was as easy as knowing what to look for and what to record. So, what did we find?

This population took a hard hit last year, with only 16 rosettes remaining. The species is rare as it is, and this plot is the largest population we have found to date on CO lands. We scouted some potential habitat in early May and found no new populations. All we did find was a cluster of 6 or so plants. So, for the time being, we have to make do with what we’ve got.  This year, we found 7 new plants and a total of 67 rosettes; which is statistically a significant increase. However, when compared to 2005, it is a significant decrease. By significant I mean we are 90% sure of detecting a 20% difference in mean population density. Here is a table of our data since 2005.

Overall, this is important information if for no other reason than the fact that the USFWS is currently being sued for deciding no to this, and another, species last year.

I still don’t know how to make this bigger.

I was also able to talk about this species at the Chicago training last week. I hope people found it interesting to hear a little about what we’re working on here, and see how the monitoring training they received in another class can be put to use. However, we presented right after lunch each day and had a hard time gauging audience interest. I only spotted one person sleeping, so that’s good right?
