Along the Verde

Tracking Pronghorn
The Conservancy is tracking pronghorn across Arizona’s largest unbroken expanse of grassland as part of a unique program aimed at preserving Arizona’s remaining pronghorn.

The pronghorn’s fate here in the Big Chino Valley of northern Arizona is linked to that of humans. That’s because beneath their hooves are large quantities of water—the very water we depend on.

Historic Ranch Conserved
The Conservancy and its partners made a significant step in the protection of the Verde River through the acquisition of the historic Shield Ranch, a biologically important property in the Verde Valley that is adjacent to the river and the Verde River Greenway Natural Area.

  • Learn why the Shield Ranch matters to river otter, beaver, bald eagles, several endangered bird species and native fish.
Along the San Pedro

San Pedro Mapping: A Bi-National Labor of Love
Hundreds of volunteers and many groups in both the U.S. and Mexico reach across the international boundary to participate in an annual mapping of the San Pedro River.

During the hottest, driest time of year, hundreds of volunteers brave triple digit temperatures, quick sand and a myriad of logistical challenges to collect data on GPS units about where the river continues to flow.

Finding Solutions: The Upper San Pedro Partnership
The Nature Conservancy is one of the founding members of the Upper San Pedro Partnership. The 21 member agencies of this consortium have implemented dozens of projects and policies to recharge, reuse, conserve and augment water within the Sierra Vista subwatershed to help sustain the San Pedro. 

Southern Arizona Rancher Goes Native
One Arizona rancher recognizes the value in keeping nature healthy—both for the environment and for the profitability of his ranch.

“We’re saving millions of gallons of water on this grass and we are cutting our use of equipment and fuel,” says Mike Mercer, an Arizona rancher who switched from growing non-native crops to native grass.
