Method synopsis

Classification of ponds into permanent, semi-permanent, and temporary categories based on historical drying patterns and hydroperiod duration from long-term data records.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Carbon Dioxide Concentrations and Efflux from Permanent, Semi-Permanent, and Temporary Subalpine Ponds (2019), Wetlands. Implementations in other papers (listed below) may differ.

1. Pond selection and classification
   Selected twelve ponds within Mexican Cut Nature Preserve representing four ponds each of permanent, semi-permanent, and temporary hydroperiod classifications based on Wissinger et al. (1999) criteria. Ponds ranged from 900 to 7800 m2 in maximum wetted area and were all located within 0.2 km radius.
   Quantities: 12 total ponds: 4 permanent, 4 semi-permanent, 4 temporary. Areas 900-7800 m2.Duration: Classification based on historical data since 1990Conditions: High-elevation subalpine ecosystem at 3640m elevation
   Equipment: GPS units, GIS software, historical data loggers
