Tortolita Preserve BioBlitz Prep

Tortolita Preserve BioBlitz

Preparations continue for the first BioBlitz at the Tortolita Preserve (TP) on 11/19/22. Tortolita Alliance is partnering with Marana Parks & Recreation, Pima Naturalists, Coalition For Sonoran Desert Protection and Arizona Game & Fish. Please reserve this date and come join us as we survey and catalogue plants and wildlife in various portions of TP. More details forthcoming.

The Washes

TP is located in the heart of the Tortolita Alluvial Fan. Over the centuries, mountain and monsoon runoff has created multiple washes that spread across the Sonoran Desert in a fan-like configuration. During a recent TP Big Loop hike, I set a waypoint at each of the small, medium and large washes that cross the TP trail within 3 miles of the Moore Road Trailhead. See the location (small flag) of these washes on the map above. There are 52 wash crossings west/north and 42 wash crossings north/east of the Moore Road Trailhead! These washes define our wonderful Sonoran Desert environment and we will be surveying some of these washes for plants and wildlife during the BioBlitz.
