TYPE LOCATION: Island of Maui, Maui County, Hawaii; Kilohana Quadrangle - 20 degrees 49' 30" north latitude and 156 degrees 18' 40'' west longitude; 150 feet north of Upper Kula Road, State Highway 377; in hospital pasture on the Haleakala Ranch 2.5 miles southeast of Pukalani Post Office.
RANGE IN CHARACTERISTICS: Depth of solum is more than 60 inches. A few pebbles, cobblestones and stones are on the surface in some places.
The A horizon has hue of 5YR through 10YR, and value and chroma of 2 or 3 moist.
The B horizon has hue of 5YR or 7.5YR, value of 3 or 4 moist, 4 or 5 dry, and chroma of 2 through 4. It ranges from loam to silty clay loam.
COMPETING SERIES: These are the Oli and Paaiki series. Oli soils are dark brown throughout and are strongly or very strongly acid. Paaiki soils have moderate to weak structure in the A horizon, silty clay texture in the lower part of the B horizon and are nonsmeary throughout.
GEOGRAPHIC SETTING: The Pane soils are on undulating to hilly uplands. Elevation ranges from 2,000 to 3,500 feet. The soils formed in volcanic ash underlain by andesite and basalt. The mean annual rainfall is 30 to 50 inches. Mean annual temperature is about 66 degrees F., average January temperature is 64 degrees F., and average July temperature is 70 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Kaipoioi, Olinda, and Kula soils. Kaipoipoi soils have chroma of 1 in the A horizon, are nonsmeary and have mean annual soil temperature of 56 degrees F. Kula soils have a mollic epipedon and are nonsmeary. Olinda soils are a silty clay loam in the B horizon.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately rapid permeability.
USE AND VEGETATION: These soils are used for pasture and a small acreage is in pineapple. The natural vegetation is bur clover (Medicago hispida), dallisgrass (Paspalum dilatatum), gosmore (Hypochaeris radicata), Natal redtop (Tricholaena repens), plantain (Plantago lanceolata), rattailgrass (Sporobolus capensis), vetch (Vicia spp.), and white clover (Trifolium repens).
DISTRIBUTION AND EXTENT: Island of Maui, Maui County, Hawaii. This series is inextensive, with a total of about 3,200 acres.
