Annual wetland hydroperiods, defined here as the number of days per calendar year that water levels exceed a specified depth, were assessed at various depths for 41 cypress dome wetlands in west-central Florida lacking substantial anthropogenic impacts on hydrology. The effects of data sampling frequency and length of data on hydroperiod calculations were also evaluated. On average, the cypress domes had at least some surface water present for approximately 215 to 325 days per year and were fully inundated for approximately 5 to 20 days. We find that approximately twice monthly water level data collection for ten years represents a minimum data sampling frequency and data length target for characterizing cypress dome hydroperiods. The results provide insights into how hydroperiods can vary in time and space while delineating typical baseline hydroperiod ranges for cypress domes in the west-central Florida study area. More broadly, and applicable to wetlands worldwide, the work underscores the need to contextualize hydroperiods relative to depth threshold and data collection characteristics in order to better understand hydroperiods within and between wetlands.

在佛罗里达州中西部地区41个柏树穹顶湿地的不同深度，对每年的湿地水文周期（此处定义为每个日历年中水位超过特定深度的天数）进行了评估，而对水文学没有重大的人为影响。还评估了数据采样频率和数据长度对水文周期计算的影响。平均而言，柏树穹顶每年至少约有215至325天存在至少一些地表水，并被约5至20天完全淹没。我们发现，十年来每月两次的水位数据收集代表了表征柏树圆顶水文周期的最小数据采样频率和数据长度目标。结果提供了关于水文周期如何随时间和空间变化的见解，同时描绘了佛罗里达州中西部研究区柏树穹顶的典型基线水文周期范围。更广泛地讲，并且适用于世界范围内的湿地，这项工作强调了需要根据深度阈值和数据收集特征来对水文期进行情境化，以便更好地了解湿地内部和湿地之间的水文期。
