“…To map ephemeral wetlands such as playas, previous efforts have successfully located greater numbers of these wetlands by combining data sources such as National Wetlands Inventory (NWI; USFWS 1982) with soils surveys, satellite imagery, and aerial photography (e.g., Guthery and Bryant 1982;Tiner 2005;Dick and McHale 2007;Bowen et al 2009Bowen et al , 2010. To make a dataset of possible playa locations, we worked with the Playa Lakes Joint Venture (PLJV) and the United States Fish and Wildlife Service (USFWS) to combine several data sources into a GIS dataset (n=15,812).…”

Many isolated wetlands that fill by rainfall, such as playas, have been affected by sedimentation in heavily modified agricultural landscapes. Conservation plantings and buffers reduce sedimentation in wetlands but also may reduce the frequency of inundation. We studied the effects of surrounding landcover on the responses of playas in southwestern Nebraska to heavy rain events using aerial photography, ground surveys, and GIS landscape analyses. Using a generalized linear mixed model, we found that playas in rangeland were more likely to become inundated than playas in cropland, and both were more likely to become inundated than playas in fields enrolled in USDA's Conservation Reserve Program (CRP), typified by tall, dense grasses. Inundation was also positively related to rainfall amount and playa size. Our results highlight the significance of maintaining playas in native prairie and underscore the importance of planting and managing appropriate mixes of native shortgrass and/or mixed-grass prairie species surrounding playas to mimic the vegetative structure of native prairie. In light of historic wetland losses, a reduction in the probability of flooding for individual playas in CRP must be weighed against the protection from sedimentation that buffers afford wetlands in cropland and other beneficial influences of CRP in the landscape.

“…Because of their widespread spatial distribution (e.g., Tiner 2003;Bowen et al 2010;Lane et al 2012) and frequent co-location with phosphorus-intensive activities (i.e., agricultural activities; Johnston 2013; Wright and Wimberly 2013), extant geospatially or socalled ''geographically isolated wetlands'' (GIWs) may serve as local or watershed-scale sinks for phosphorus-entrained runoff (e.g., Zhang et al 2009). A GIW can be defined as a wetland system, typically depressional, with no obvious hydrologic surface connection to downstream systems.…”

The translocation of phosphorus (P) from terrestrial landscapes to aquatic bodies is of concern due to the impact of elevated P on aquatic system functioning and integrity. Due to their common location in depressions within landscapes, wetlands, including socalled geographically isolated wetlands (GIWs), receive and process entrained P. The ability of depressional wetlands, or GIWs, to sequester P may vary by wetland type or by land use modality. In this study we quantified three measures of P sorption capacities for two common GIW types (i.e., emergent marsh and forested wetlands) in two different land use modalities (i.e., agricultural and least impacted land uses) across 55 sites in Florida, USA. The equilibrium P concentration (EPC 0 ) averaged 6.42 ± 5.18 mg P L -1 (standard deviation reported throughout); and ranged from 0.01-27.18 mg P L -1 ; there were no differences between GIW type or land use modality, nor interaction effects. Significant differences in phosphorus buffering capacity (PBC) were found between GIW types and land use, but no interaction effects. Forested GIWs [average 306.64 ± 229.63 (mg P kg -1 ) (lg P L -1 ) -1 ], and GIWs in agricultural settings [average 269.95 ± 236.87 (mg P kg -1 ) (lg P L -1 ) -1 ] had the highest PBC values. The maximum sorption capacity (S max ) was found to only differ by type, with forested wetlands (1274.5 ± 1315.7 mg P kg -1 ) having over three times the capacity of emergent GIWs (417.5 ± 534.6 mg P kg -1 ). Classification trees suggested GIW soil parameters of bulk density, organic content, and concentrations of total P, H 2 O-extractable P, and HCl-extractable P were important to classifying GIW P-sorption metrics. We conclude that GIWs have high potential to retain P, but that the entrained P may be remobilized to the wetland water column depending on storm and groundwater input P concentrations. The relative hydrologic dis-connectivity of GIWs from other aquatic systems may provide sufficient retention time to retain elevated P within these systems, thereby providing an ecosystem service to downstream waters.

“…Norton County ashes in particular are consistent with subaqueous deposition due to their dense packing and horizontal laminations (Landes, 1928). Standing water in the High Plains is currently restricted to small sandhills lakes (Gutentag et al, 1984), as well as ~22,000 extant playas in Kansas alone (Bowen et al, 2010).…”

“…They likely record sediment influx events in a reliable stratigraphic order as they concentrate local runoff and entrap sediments (Bowen et al, 2010) including volcanic ash (Cornwell, 1984). Playas are common both on the present surface of the High Plains, and within the Miocene Ogallala Formation (Holliday et al, 1996), and are thus the favored depositional environment for the Calvert ash.…”

Difficulties in correlation within continental clastic basins arise from the common shortage of reliable marker beds, which limits characterization of geological relationships. In the High Plains of the central United States, an improved understanding of the stratigraphic architecture of the terrestrial Ogallala Formation can be used to improve management of depleted groundwater resources, illuminate the causes of fluvial aggradation, enhance the western US climatic record, and strengthen the temporal precision of the North American Land Mammal Ages. Such relationships can be derived from chronostratigraphic information provided by abundant, dateable, volcanogenic zircon in volcanic ashes and fluvial beds, which provide the first highprecision (ca. 1-5% uncertainty) radioisotopic dates for the Ogallala Formation. These zirconbearing ashes appear to have travelled ~1350 km from their interpreted sources within the Bruneau-Jarbidge and Twin Falls volcanic centers in Idaho, suggesting that volcanogenic zircon has the previously unappreciated potential to time-stamp terrestrial surfaces at great distances from contemporaneous magmatic centers. Volcanic ash depositional ages are consistent with fluvial maximum depositional ages, indicating that deposition of common lithologies within the Ogallala Formation, including sands, paleosols, and volcanic ashes can be reliably dated with modern, high-precision techniques. Zircon U-Pb LA-ICP-MS results suggest diachronous aggradation of the Ogallala Formation in Kansas, particularly deposition of an inferred Norton lobe in northern Kansas that initiated prior to ~12.5 Ma and aggraded to near-modern levels by 11.7 Ma, measurably earlier than the ~8-9.5 Ma deposition of an inferred Ellis lobe over a bedrock high in central Kansas. The observed diachronous relationships predict aquifer anisotropy that could inform efforts to develop numerical groundwater models designed to forecast aquifer response to different conservation strategies. iv ACKNOWLEDGEMENTS
