Island Plant Adaptations Guide Stop 6

Wind is an ever-present factor in the climate of San Miguel Island, and coastal goldenbush has adapted to this windy environment in several ways. The plant's low-growing form offers minimal wind resistance, while its deep roots and tough woody stems help it remain firmly anchored in the soil. Thick, leathery leaves help to prevent desiccation. Wind also plays a role in the natural spread of coastal goldenbush. The seeds of this plant have many hair-like bristles that act like tiny wings to aid in wide dispersal.

Another wind-adapted plant is the San Miguel Island sagebrush. This plant's low-trailing branches and needle-like foliage reduce the physical damage and moisture loss that accompanies windy conditions.
