Tortolita Preserve Horseback Ride-1/7/26 Went on a 2-hour horseback ride in the Tortolita Preserve (TP) last Saturday! I have been wanting to do this for some time, and so glad I did it.

The wildflower bloom this year should be prolific, as we had normal monsoon rainfall in 2025 and a warm fall/early winter. It's early, so only one wildflower and one nasty grass were observed. Brittlebush has started to bloom: Brittlebush-Upper Javelina Trail (1/18/26) Sadly, Buffelgrass is now appearing along the higher elevations of th

Saguaro Research-Tortolita Preserve Tortolita Alliance (TA) has proposed to conduct a Saguaro Survey/Inventory within the Tortolita Preserve.
