Haro soil and landscape
Soil profile: The Haro series consists of shallow, well drained soils formed in glacial drift mixed with colluvium from metasedimentary bedrock. (Soil Survey of San Juan County, Washington; by By Michael Regan, Natural Resources Conservation Service)
Landscape: Haro soils are on south facing hillslopes and mountain slopes at elevations near sea level to 2200 feet. Slopes are 5 to 75 percent. Mean annual precipitation is about 26 inches. Mean annual air temperature is about 50 degrees F.
TAXONOMIC CLASS: Loamy, isotic, mesic Lithic Ultic Haploxerolls
Mean annual soil temperature - 50 to 54 degrees F.
Soil moisture control section - dry 75 to 90 days following summer solstice
Mollic epipedon thickness - 10 to 20 inches (A and Bw horizons)
Base saturation by ammonium acetate greater than 50 percent from the soil surface to the top of a lithic contact
Base saturation by sum of cations less than 75 percent from the soil surface to the top of a lithic contact
Depth to lithic contact - 10 to 20 inches
Reaction - moderately acid or strongly acid
Volcanic glass - less than 5 percent throughout
Particle size control section:
Clay content - 5 to 18 percent
Rock fragments - 0 to 35 percent gravel, 0 to 5 percent cobbles, 0 to 35 percent total
USE AND VEGETATION: These soils are used mainly for home sites, pasture, and wildlife habitat. Potential natural vegetation consists of Oregon white oak, Pacific madrone, Roemers fescue, western brackenfern, trailing blackberry, baldhip rose, oceanspray, and common snowberry.
DISTRIBUTION AND EXTENT: Northwest Washington; MLRA 2, Northern Part. Series is of small extent.
