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. We collected stem and basal diameter measurements of three native plant species at Nakula Natural Area Reserve, Maui, from 2016-2019 and numerous environmental variables to examine how rain, fog and soil moisture influence plant water deficit and growth.

We collected stem diameter measurements of three native plant species at Nakula Natural Area Reserve, Maui, from 2016-2019 and numerous environmental variables to examine how rain, fog, soil moisture, and associated variables influence plant water deficit and growth. We also collected seedling growth and survival data within plots where grass was removed, and control plots (no grass removal), to assess if and how grass removal influenced seedling growth and soil moisture.

Non-native grass removal as part of a larger restoration strategy has been demonstrated to assist in natural recruitment of important native plant species on the island of Maui. Seedling size class data were collected to assess whether there were differences in Dodonaea viscosa seedling recruitment and survival between grass-control plots and those dominated by non-native grass in the Nakula Natural Area Reserve on Maui Island, and between grass-controlled sites.

Non-native grass removal as part of a larger restoration strategy has been demonstrated to assist in natural recruitment of important native plant species on the island of Maui. We monitored 90 Dodonaea viscosa seedlings across three sites within grass removal treatments to understand seedling survivorship, and whether non-native grass regrowth affected survivorship, in the Nakula Natural Area Reserve on Maui Island.

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...
