This study assessed the conditions of wetland hydrology, hydrophyte and soil under different state and federal conservation programs, and then identified the restorable potential of conserved playas. The distribution of hydrology and hydrophyte were geospatially examined through annual tracking the quantity and quality of wetlands on historical hydric soil footprints under different conservation programs in the Rainwater Basin in Nebraska, USA during 2004–2015. The results show that the historical hydric soil footprints with the conservation programs had significantly better performance in ponded water and hydrophyte than non-conserved wetlands. The yearly average of ponded water areas within footprints varies at 12.59% for the Waterfowl Production Areas (WPAs), 14.78% for Wildlife Management Areas (WMAs), 27.37% for Wetlands Reserve Program’s conservation easements (WRPs), and 1.86% for non-conserved wetlands, respectively. The yearly average of hydrophyte plant community coverage within footprints reaches at 77.51% for WPAs, 79.28% for WMAs, and 66.53% for WRPs, and 8.82% for non-conserved hydric footprints. Within conserved lands, Massie/Water soil series demonstrated the prominent ability to hold ponding water, especially in the ponded footprints with higher ponding frequency. Nevertheless, the proportion of Fillmore, Rusco or Butler soil series roughly decreased when the ponding water frequency increased. The areas, with high likelihood to be restored, are the places between annual ponding/hydrophyte covered areas and 11 years’ maximized ponding/hydrophyte areas.

保护显着改善了湿地条件:评估处于不同保护状态的普拉亚湿地

这项研究评估了不同州和联邦保护计划下的湿地水文学,水生植物和土壤的条件,然后确定了保护性普拉亚的可恢复潜力。在2004-2015年期间,通过在美国内布拉斯加州雨水盆地的不同保护计划下,通过年度跟踪历史水文土壤足迹上湿地的数量和质量,对水文和水生植物的分布进行了地理空间检查。结果表明,采用保护程序的历史性水土足迹在蓄水池和水生植物中的表现明显优于非保护性湿地。水禽生产区(WPA)的年平均足迹水域变化为12.59%,野生动物管理区(WMA)的年平均变化为14.78%,27。湿地保护计划的保护地役权(WRP)分别为37%和非保护湿地的1.86%。WPA的年平均水生植物群落覆盖率分别达到WPA的77.51%,WMA的79.28%,WRP的66.53%和非保守的水文足迹的8.82%。在受保护的土地上,Massie / Water土壤系列显示出了保持积水的突出能力,尤其是在积水频率较高的积水足迹中。然而,随着积水频率的增加,Fillmore,Rusco或Butler土壤系列的比例大致下降。极有可能恢复的区域是介于年度捕捞/水生植物覆盖区域和11年最大化的捕捞/水生植物区域之间的区域。WPA的年平均水生植物群落覆盖率分别达到WPA的77.51%,WMA的79.28%,WRP的66.53%和非保守的水文足迹的8.82%。在受保护的土地上,Massie / Water土壤系列显示出保持积水的突出能力,尤其是在积水频率较高的积水足迹中。然而,随着积水频率的增加,Fillmore,Rusco或Butler土壤系列的比例大致下降。极有可能恢复的区域是介于年度捕捞/水生植物覆盖区域和11年最大化的捕捞/水生植物区域之间的区域。WPA的年平均水生植物群落覆盖率分别达到WPA的77.51%,WMA的79.28%,WRP的66.53%和非保守的水文足迹的8.82%。在受保护的土地上,Massie / Water土壤系列显示出保持积水的突出能力,尤其是在积水频率较高的积水足迹中。然而,随着积水频率的增加,Fillmore,Rusco或Butler土壤系列的比例大致下降。极有可能恢复的区域是介于年度捕捞/水生植物覆盖区域和11年最大化的捕捞/水生植物区域之间的区域。Massie /水土系列证明了保持积水的突出能力,尤其是在积水频率较高的积水足迹中。然而,随着积水频率的增加,Fillmore,Rusco或Butler土壤系列的比例大致下降。极有可能恢复的区域是介于年度捕捞/水生植物覆盖区域和11年最大化的捕捞/水生植物区域之间的区域。Massie /水土系列显示了保持积水的突出能力,尤其是在积水频率较高的积水足迹中。然而,随着积水频率的增加,Fillmore,Rusco或Butler土壤系列的比例大致下降。极有可能恢复的区域是介于年度捕捞/水生植物覆盖区域和11年最大化的捕捞/水生植物区域之间的区域。
