Readers of this blog know that I/we have enjoyed a particularly good partnership with our BLM folks for the last nearly decade, in huge part because of rangeland management specialist and Spring Creek Basin herd manager Mike Jensen.
Our PZP program was implemented during the 2011 roundup, before Mike returned to herd manager duties (he was herd manager here first in the early 2000s), but Mike has been an absolutely staunch supporter of the program. It was under Mike’s leadership that we were able to get bait trapping solidified as the capture method of choice (when the time comes), and because of Mike’s dedication to vegetation monitoring, for the 2020 herd management area plan update, we had the data necessary to allow the increase in AML (appropriate management level) from 35 to 65 adult horses to 50 to 80 adult horses. That, combined with the very successful PZP program, has meant an astounding 13 years to date since the last roundup and removal of any Spring Creek Basin mustangs.
Mike is the BLM partner every advocate wishes for and we have been so very fortunate to have.
Under Mike’s leadership, Spring Creek Basin Herd Management Area is a model that other BLM managers and advocates can aspire to. (That’s not arrogance; that’s pure gratitude.)

As I described in yesterday’s post, last week, Mike and Tres Rios Field Office Manager Derek Padilla came to Spring Creek Basin for the field trip with Colorado Wild Horse Working Group members. I take every opportunity offered to describe Mike’s work ethic, partnership and support of our mustangs to anyone who will listen, but this was the first opportunity for group members and our Colorado advocates to see him in action as he talked about the history of Spring Creek Basin as a herd management area and our accomplishments in both herd management and the projects we’ve completed for the benefit of the mustangs. Naturally, everyone wants a Mike clone for their areas. 🙂
By the time we reached the day’s end goal and turnaround spot – the northwest-valley water catchment we built in 2022 – we were down to our local advocates and a Jeep-full of advocates from the other herds.



And because Mike retires Friday from a long (30 years) career with the Bureau of Land Management, we local advocates wanted to take advantage of the last opportunity we’d likely have Mike in Spring Creek Basin to mark the occasion, wish him well and give him a token of our appreciation.

Thank you, Mike, for being such a champion for wild horse management here in Spring Creek Basin, for being a true partner, for being one of the people I respect most in this world. We wish you well in retirement! Don’t be a stranger. 🙂

As you wrote:
“Spring Creek Basin Herd Management Area is a model that other BLM managers and advocates can aspire to.”
I wish that other BLM managers WOULD aspire OR possible would be allowed to use the example Mike set here in Spring Creek. It sure does make absolutely clear what is possible.
I wont rant, but in too many other HMAs the roundups continue!
None of it is easy. A lot of hard work has come together here combined with some fortuitous and very lucky happenings.
The best to you, Mike Jenson! It has been a true honor and pleasure to know you! Spring Creek Basin mustangs have been the real winners under your leadership!
Dave and Nancy
Thanks, Mom and Dad! 🙂
Thank you to Mike. And thank you for your wonderful tribute to him, TJ. Those of us who love the Spring Creek Basin mustangs know how important Mike has been to developing a model HMA and how valuable someone like him can be for the future of wild horses. We have been so blessed to have Mike be “our BLM guy” and could only hope that one day his example would be the norm. We are grateful for him and wish him Godspeed. Praying for a replacement worthy of his shoes.
Excellently said, Sue! Thank you! 🙂
The very best to Mike! Hope he has a great retirement!
We do wish Mike a great retirement. 🙂 He has earned it!
Thank you Mike for all you’ve done for the Mustangs of Spring Creek Basin.
Thanks for the well wishes to Mike! 🙂
