Overview of the Mojave
Plant Adaptations
Xerophytes are plants that have developed special means of storing and conserving
water. To reduce transpiration, direct cooling air flow, shade themselves, and/or
reflect hot sunlight, they often have few leaves, or have spines, thorns, or hairs
instead; in some cases they use only their green “skin” to perform
photosynthesis. Some
xerophytes have leaves that are tough and waxy or coated with shiny oils, which
also cuts down on transpiration, or they have small, fluttery leaves that help to cool
the plants. Some species have spongy, shallow roots to take advantage of even the
smallest amounts of rain, plant tissues that can store large amounts of water for
later use, or ribs that direct moisture to the plant’s roots. The Joshua tree
(Yucca brevifolia),
various types of
cacti,
and Mojave sage (Salvia mojavensis) are all examples of Mojave xerophytes.
