This dataset contains the approximate location of 59 wetlands that were monitored as part of the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). Note, these were preliminary points used for locating the wetlands in the field and they may not fall directly within a wetlands boundary. The later surveying of pond boundaries provides more accurate locations. These point locations were collected with a Garmin GPSmap62 unit. The mention of firm, product, or trade names is done so for informative purposes only and does not constitute and recommendation or endorsement by the federal government.

This Data Release represents geospatial and tabular data for a study investigating linkages between local terrain and wetland hydroperiod and was supported by the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). This dataset contains wetland water level data from Saint Marks National Wildlife Refuge (SMNWR). Data include records of water level and water temperature measurements from select wetlands beginning in July 2010 and ending in 2019. Not all wetlands span this entire period as different phases of studies resulted in different time periods of data collection. Instrumentation included a staff gage and a non-vented continuous logging pressure transducer that logged data at 1-hour...
This dataset contains boundary polygons from 59 wetlands, that were monitored as part of the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI) from Saint Marks National Wildlife Refuge (SMNWR). These sites covered a range of sizes, shapes, topographic and vegetative characteristics that were deemed to be representative of wetlands within the study area. Ground-based surveys of wetland perimeters were made using a Trimble R8 Real Time Kinematic Global Positioning System (RTK-GPS). Surveys generally followed the lowest extent of saw palmetto (Serenoa repens), which is a reliable indicator of the upper limits (elevation) of sustained inundation. In instances where palmetto was absent,...

This dataset contains records of water level and water temperature measurements from select wetlands at Saint Marks National Wildlife Refuge. These data were collected as part of the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). Beginning in July 2010, hydrologic monitoring equipment was installed in 24 wetlands. Instrumentation included a staff gage and a non-vented continuous logging pressure transducer (Onset Comp U20) that logged data at 1-hour intervals. An additional 35 sites were instrumented in January 2014. Data for individual wetlands covers different time periods based on different phases of studies and sensor battery failures. In shallow, ephemeral wetlands these...

This dataset is a set of transition probabilities that were elicited from a group of relevant experts during a structured decision-making workshop. Each value is the probability of a wetland in a given state undergoing a transition to another state during a single time step, given a potential management action is taken.
