We discuss a recent paper which evaluated the hydrologic changes resulting from a pond‐and‐plug meadow restoration project in the Sierra Nevada Mountains of California. In the study, measurements of streamflow into and out of the meadow suggested late‐summer baseflow increased as much as five‐fold when compared with prerestoration conditions. However, the volume of streamflow attributed to the restored meadow (49,000–96,000 m³ over four months) would require that 2.5–4.8 m of saturated meadow soils drain during summer months. The groundwater data from this meadow record only 0.45 m of change over this timeframe, which is less than might be expected from plant use alone (0.75 m), suggesting this restored meadow may be acting as a water sink throughout summer rather than a source.

讨论：Luke JH Hunt，Julie Fair和Maxwell Odland的“草甸恢复增加了加利福尼亚内华达山脉的基流和地下水存储”

我们讨论了最近的一篇论文，该论文评估了加利福尼亚内华达山脉的池塘和插塞草地恢复项目所引起的水文变化。在该研究中，对流入和流出草地的水流的测量表明，与恢复前的条件相比，夏末的基流增加了五倍。然而，归因于已恢复草地的水流量（四个月内为49,000-96,000 m ³）将需要在夏季月份排出2.5-4.8 m的饱和草地土壤。在该时间段内，该草甸的地下水数据仅记录了0.45 m的变化，这比单独使用植物时的预期变化（0.75 m）要少，这表明该恢复的草甸可能在整个夏天起着水槽的作用，而不是源头。
