Description: Bands of shorthair meadow are found around lakes in the high Sierra Nevada of California. A hypothesis, based on observations in the Kings Canyon National Park, to explain the development of these meadows is offered: Boulders form the foundation upon which American-laurel, Sierra bilberry, and moss combine to produce thick mats. The lower layers of the mats are gradually converted to acid bog or mucksoil, which becomes in effect the C horizon of soil supporting the shorthair meadow type. Herbaceous plants change the upper layers and, thereby, produce an A horizon and a succession leading to a shorthair climax.
Keywords: mountain meadows; meadow development; soil horizons; Calamagrostis breweri; Sphagnum; Kings Canyon National Park; Charlotte Lake Meadow
