Cave Creek Ecosystem IBA

 

JeweloftheCreekSite Description: Cave Creek Ecosystem IBA is located in the Sonoran Desert Eco-region, specifically the Arizona Upland subdivision of the Sonoran desert scrub biome. The IBA encompasses cottonwood/ willow/sycamore and mesquite bosque riparian areas along with associated desert scrub uplands. Flowing or standing water is present in many places and there is considerable elevation change and habitat diversity in this IBA. Much of the land is publicly owned and in a natural undisturbed state. It is an exceptional example of a lowland mesic and xeric southwestern riparian community with adjoining undisturbed high quality upland Sonoran desertscrub vegetation. The perennial water found in reaches of Cave Creek supports a healthy high quality cottonwood/willow and sycamore vegetation and ecological community.

Conservation Issues: The Cave Creek Complex Fire ravaged much of the Cave Creek watershed in 2005.  The proposed IBA was largely spared.  However, subsequent floods damaged low lying vegetation, washed away soil and exposed considerable cobble that remains today.

There are two active water rights at Seven Springs, both of which allow for withdrawals from Seven Springs Wash.  One is a privately held right for 90 acre feet/year that predates the Forest Service.  This water is available for domestic and agricultural use.  The permittee withdraws water for a commercial bottled water operation.  Water use is monitored by the Cave Creek Ranger District of the Tonto National Forest, which has a right of 488 acre feet/year to maintain the riparian vegetation and provide water for recreational purposes. Sufficient flow is being maintained in Seven Springs Wash and Cave Creek, as riparian vegetation continues to thrive in these drainages.
