Hassayampa River Preserve

In January 2017, after more than a quarter-century as a Nature Conservancy preserve, the preserve will have a new partner and part owner: Maricopa County’s Parks and Recreation Deparment.

The Nature Conservancy owns the Hassayampa preserve, but it is currently under the management of Maricopa County Parks and Recreation. Events listed on this page are still current. Additional information about the preserve can be found at the Maricopa County web site.

For most of its 100-mile course through the desert, the Hassayampa River flows only underground. But within the preserve its crystal clear waters emerge, flowing above ground throughout the year. This lush streamside habitat is home to some of the desert’s most spectacular wildlife. Yet many of them have become dangerously imperiled as riparian areas have disappeared from the Arizona landscape.

In the Sonoran Desert, riparian areas nourish cottonwood-willow forests, one of the rarest and most threatened forest types in North America. An estimated 90% of these critical wet landscapes have been lost, damaged or degraded in the last century. This loss threatens at least 80% of Arizona wildlife, which depend upon riparian habitats for survival.

Exploring the Outdoors as a Nature Ranger

Nine-year-old Sydney Smith wanted to share her love of nature with other kids. That’s why in 2009 she and her mother started the Nature Rangers program at the Hassayampa River Preserve. 

“I want kids to know that if we care about wildlife, we can save the world,” said Sydney. The program engages children in kindergarten through sixth grade in exploring nature and learning about the importance of preservation and conservation. Specific activities include bird banding, monarch tagging, hiking and other programs. 

For information on how to get involved in Nature Rangers, contact Bernadine McCollum at the Hassayampa River Preserve: (928) 684-2772.

Hassayampa Slideshow

Hassayampa River Preserve begins a new chapter with Maricopa County Parks and Recreation Department.

Young visitors in particular delight in spotting the many species of lizards that dart amidst the underbrush and woody debris, including the rare Gilbert’s skink. Along trails you can see the tracks of animals drawn to the river’s edge: mule deer, javelina, raccoon, bobcat, ring-tailed cat, and even mountain lion.

Spring-fed Palm Lake is a unique four-acre pond and marsh habitat. The marshy pond habitat attracts an impressive array of water birds such as the great blue heron, white-faced ibis, and pied-billed grebe. The large willows around the lake provide important nesting habitat for the endangered southwestern willow flycatcher.

What You'll See
At Hassayampa River Preserve you may see any one of the 280 species of birds living, nesting, or migrating along the riparian corridor. Perched atop the massive trees and dead snags are some of Arizona’s rarest raptors, like the zone-tailed hawk, the black hawk, and the Harris hawk. Lucky birders may sight a Mississippi kite or the elusive yellow-billed cuckoo.

Trails & Information
Trails at the Hassayampa are self-guided, leading you along the lush river bottoms, across the river’s floodplain, through majestic cottonwood-willow forests and dense mesquite bosques (Spanish word for forest) found only near desert waterways.  On your walk, a brilliant vermilion flycatcher or an Abert’s towhee on the wing might catch your eye.  Also a part of the trail system is a loop around Palm Lake where waterfowl, otherwise uncommon in the desert, are a major attraction.

Docent-led guided walks are available. Please call (928) 684-2772, to find out about regular walks or to schedule a walk for your group. Download trail guide of the preserve. (.pdf, 1.3MB)
