Water level data from select wetlands at Saint Marks National Wildlife Refuge:2010 - 2015

Small, seasonal pools and temporary ponds (<4.0 ha) are the most numerous and biologically diverse wetlands in many natural landscapes. Thus, accurate determination of their numbers and spatial characteristics is beneficial for conservation, management, and persistence of biodiversity associated with these freshwater systems. We examined the utility of a topographic position index (TPI) landscape classification as a means to identify and classify depressional wetlands. We also assessed relationships between topographic characteristics and hydroperiod of known wetlands to allow hydrological characteristics to be extended to non-monitored locations. The data included herein were used to evaluate relations between topographic characteristics and wetland hydroperiod. The GIS files represent wetlands generated using the landscape classification to identify depressional areas in the landscape that were similar to field identified features. A table containing the data used to evaluate the relations between hydroperiod and topographic characteristics is also provided.
