Periods of rapid sedimentation between ca. 700 to 1100 cal yr BP and ca. 4100 to 4400 cal yr BP at San Bernardino are associated with a highstand at pluvial Lake Cochise, the presence of aquatic pollen taxa in New Mexican packrat middens and periods of incision in river channels in the San Pedro and Santa Cruz river valleys. These results suggest that ci´enega deposits represent records of hydrological change and, as such, are important but under-utilized repositories of paleoclimatic information. These results also inform ci´enega restoration efforts by highlighting the importance of subsurface and surface water flow through these environments. Effective restoration requires the development of conditions where groundwater maintains surface vegetation and seasonal floods are allowed to inundate the surface. r 2006 Elsevier Ltd.

Introduction  \nSince the late 1800s, natural wetlands in arid and semi-arid desert grasslands of the American Southwest and Northern Mexico have largely disappeared. Historically, desert wetlands, or cie´negas, were well distributed across the landscape and a valuable resource for native animals, plants, and prehistoric cultures (Davis et al., 2002) . Ci´enegas are low gradient wetlands found between 1000 and 2000 m elevation asl in the American Southwest  \n 􀀂 Corresponding author.

These wetlands form in headwaters and loworder streams with high groundwater tables, promoting surface inundation (Hendrickson and Minckley, 1985) . As Euro Americans arrived in the Southwest, ci´enegas were converted to agricultural and grazing fields, and more recently have been used as a source of groundwater for growing communities in the region (Hendrickson and Minckley, 1985) . Since 1900, erosion associated with post-settlement channelization, and drawdown of local water tables have dried up most ci´enega environments (Bryan, 1928; Hendrickson and Minckley, 1985) . Many of the region’s remaining ci´enegas are now maintained through artificial impoundments and wells that draw water from depths far below the surface.  \nRecent desiccation and erosion leading to arroyo (i.e., incised channel) development caused by land usage is in contrast to prehistoric periods of climatically driven downcutting (Waters and Haynes, 2001) . Waters and Haynes (2001) use cut and fill sequences from the Santa Cruz River (SC) and San Pedro Valley (SPV), Arizona to study Holocene alluvial down-cutting periods. Their research suggests that prior to extensive grazing and agriculture, down cutting in the larger river systems took place during periods of increased precipitation.
