“…However, it can also occur in the absence of rainfall, especially during the summer when the more frequent (Juvik and Ekern, 1978). The interception of fog by vegetation is an important source of water for high-elevation forests in Hawai'i, particularly during the drier summer months (Juvik and Nullet, 1995).…”

“…Where fog is persistent, the interception of this moisture by vegetation has been shown to be a significant component of the water budget (Ekern, 1964;Juvik and Ekern, 1978;Juvik and others, 1993;Juvik and Nullet, 1995;Scholl and others, 2007). Fog interception occurs through the processes of turbulent diffusion and gravitational sedimentation of droplets onto vegetative surfaces, mainly leaves or needles (Bruijnzeel and others, 2005).…”

COVER: Map of the Island of Hawaiÿi showing the relative distribution of estimated mean annual recharge for baseline conditions. Estimated recharge is shown using a spectral color scale with red representing very low recharge and violet representing very high recharge. White areas represent zero estimated recharge.

This report documents the development of a daily water-budget model for computing groundwater recharge for the entire Island of Hawai'i and the application of the model to estimate mean recharge for various land-cover and rainfall conditions. The development of a submodel for the Kona area and the application of the model to estimate historical groundwater recharge in the Kona area during the period 1984-2008 also are documented. Recharge estimates from this study are compared to recharge estimates used by the State of Hawai'i Commission on Water Resource Management (CWRM) in setting the sustainable yields (maximum allowable pumping rates) of Hawai'i aquifer systems in the 2008 version of the Water Resource Protection Plan (2008 WRPP). Groundwater Recharge on Hawai'iEstimated mean annual recharge on the Island of Hawai'i is 6,594 million gallons per day, which is about 49 percent of mean annual rainfall. Recharge is highest on the windward slopes of Mauna Loa, below the tradewind inversion, and lowest on the leeward slopes of Kohala and Mauna Kea ( fig. ES1). Local recharge maxima also occur on (1) the higher elevations of windward Kohala, (2) windward Mauna Kea below the tradewind inversion, (3) windward Kïlauea, (4) the middle elevations of southeastern Mauna Loa, and (5) the lower middle elevations of leeward Mauna Loa and southwestern Hualälai, in the Kona area. Local recharge minima also occur on (1) Mauna Kea and Mauna Loa, above the tradewind inversion, (2) the northern tip of Kohala, (3) leeward Kïlauea, (4) the southern tip of Mauna Loa, and (5) the northwestern slopes of Mauna Loa and Hual...

“…The factor of 5 is probably most appropriate for sites having omnidirectional exposure to clouds, such as at the summit of Hualalai. More recently, Juvik and Nullet (1995) cross-sectional area of the rain gage. Similar gages were used by Juvik and Ekern (1978) and Juvik and Nullet (1995).…”

“…More recently, Juvik and Nullet (1995) cross-sectional area of the rain gage. Similar gages were used by Juvik and Ekern (1978) and Juvik and Nullet (1995). Because rainfall and fog on the western slope of Mauna Loa are almost exclusively associated with the upslope wind (Juvik and Ekern, 1978), it is reasonable to assume that the fog intercepted by the gage is related to the projected vertical area of the gage as opposed to the entire surface area.…”

“…This water, which could potentially be lost, is then retained and distinguishes cloud forests from other forest types (Stadtmüller 1987). The occurrence and extraction of water from cloud or fog increases atmospheric humidity, allowing these forests to occur in climatic regions where the matrix vegetation is predominantly drier or very seasonal (Gioda et al 1995;Juvik & Nullet 1995).…”

The upper montane forests in the southern and southeastern regions of Brazil have an unusual and discontinuous geographic distribution at the top of the Atlantic coastal mountain ranges. To describe the floristic composition and structure of the Atlantic Forest near its upper altitudinal limit in southeastern Brazil, 30 plots with 10  10 m were installed in three forest sites between 2,200 and 2,300 m.a.s.l. at Serra Fina. The floristic composition and phytosociological structure of this forest were compared with other montane and upper montane forests. In total, 704 individuals were included, belonging to 24 species, 15 families, and 19 genera. Myrsinaceae, Myrtaceae, Symplocaceae, and Cunoniaceae were the most important families, and Myrsine gardneriana, Myrceugenia alpigena, Weinmannia humilis, and Symplocos corymboclados were the most important species. The three forest sites revealed differences in the abundance of species, density, canopy height, and number of stems per individual. The upper montane forests showed structural similarities, such as lower richness, diversity, and effective number of species, and they tended to have higher total densities and total dominance per hectare to montane forests. The most important species in these upper montane forests belong to Austral-Antartic genera or neotropical and pantropical genera that are typical of montane areas. The high number of species shared by these forests suggests past connections between the vegetation in southern Brazilian high-altitude areas.
