Month 11-CO State BLM Office

Hi everybody, I’m a bit over due for a blog. This is my eleventh month at the CO state BLM office! It is also my last full month on the job. So, what have I been up to?

Since returning from all the holiday fun my most recent task has been to inventory all the information known about the CO threatened species Sclerocactus glaucus. This is one of the species we monitor here at the state office, along with much help from the field offices. I went on a river trip surveying for additional populations over the summer, which I believe I talked about in an earlier blog.

The inventorying is going well so far, there is a lot of data to sort through from various sources. I’m trying to get a clear picture of how many plants we know exist, where they’re at, an idea of occupied habitat, and what portion of the population has any protections. This is all in an effort to get this species delisted.  There are a lot more plants on the landscape than previously thought and our monitoring efforts have shown density is higher than previously believed.

The largest problem I’m facing is how to deal with dated occurrence reports and geographic data without survey dates or population estimates. Luckily we do have a lot of reliable, accurate, and recent data, but tweezing out information from less recent, less reliable records has been difficult.

I also recently finished an annual report of our rare species monitoring for 2015. This is more or less just for our office here, but information for certain species will also be sent to field offices and partners. It’s important to summarize our monitoring activities and results from year to year, and especially helpful to new interns becoming familiar with these species and our monitoring efforts.

As I said, this is my last full month working with Carol here in Colorado. I have four more weeks, and will leave in mid-February, but it’s strange to think it’s all coming to an end. In my next, my last, blog I’ll share some parting thoughts and future plans!


Here are two pictures of a plant I really like, and saw for the first time over the summer.
