OUR WORK: ECOLOGICAL MONITORING

Lloyd’s Mariposa Cactus

  • Southern Texas, USA

  • To determine if detection dogs can detect this tiny and elusive rare cactus to help better understand its range and find new populations

  • Federally protected Lloyd’s Mariposa cactus

  • Texas Parks & Wildlife Department, Conservation License Plate Program

The dogs can search quickly and find that specific species of cactus in the desert, allowing us to find new, not yet mapped populations, which is critical to the preservation of this species.

Ecological monitoring happens for plants, too. Our team was in southern Texas working to find Lloyd’s mariposa cactus (Sclerocactus mariposensis), a federally protected species, and it was the first time conservation dogs had been deployed to find it.

Its unique and adorable look is actually part of why it is so endangered. Beyond environmental contamination, destruction by off-road vehicles, and grazing, this cactus was heavily pursued for private collections, an activity that is now illegal.

Now, due to its rarity, it is challenging to locate. We are hoping that newly collected data will contribute to the continued survival and protection of this cactus.

Of particular interest with this cactus, was to deploy the dogs at different times of year, including when the plant was flowering to ensure that the dogs are capturing all variations of scent of this plant. Such variations help build the complete “scent picture” for the dogs, allowing us to confirm it’s possible to successfully find this plant at different times of the year. 
Even after all this time and experience working with conservation dogs, we continue to be amazed by the nose of a dog!

A special thank you to our amazing supporters for making work like this possible. We want to thank Texas Parks & Wildlife Department as well as the Conservation License Plate Program, for helping to support this novel project. 

Your support makes novel pilot projects like this work possible. THANK YOU!
