Summary
Fog has been demonstrated to support plant growth, survival and ecosystem maintenance spanning rainfall and elevation gradients across the world. Persistent fog and strong winds on high mountain slopes in Hawaiʻi create a unique ecological environment. To better understand the effect of fog and rainfall on soil moisture responses, we installed six soil moisture sensors across three sites at a depth of 5 cm. We condensed soil moisture data into mean daily responses (increase/decrease) and compared these to days classified by precipitation type (clear, fog, rain, or rain + fog). To explicitly test whether non-native grass removal affected responsiveness of surface soils to precipitation events, we then identified days when soil moisture [...]

We condensed soil moisture data into mean daily responses (increase/decrease) and compared these to days classified by precipitation type (clear, fog, rain, or rain + fog). To explicitly test whether non-native grass removal affected responsiveness of surface soils to precipitation events, we then identified days when soil moisture increased or decreased, grouping observations from grass treatment/grass control plots and compared these to days classified by precipitation type, described above.

Data were used to evaluate how soil moisture responds to fog and/or rainfall events. Data can also be used to determine whether there were differences in response to fog and rainfall events between areas where non-native grass was removed, and control plots dominated by non-native grass within Nakula NAR.
