8. Suck it up
Since scrub habitat is xeric (dry), the plants that inhabit this area
are well adapted to living in this environment. For example, many plants
have small hairs (pubescence), waxy leaves or leaves with edges turned
inward. This minimizes the amount of water that is lost through
evaporation and tends to trap water found in the atmosphere. An example
of a plant that uses hairs to trap moisture rusty lyonia (Lyoniaferruginea).
These hairs give the new foliage a 'rusty' color, hence the name.
The prickly pear cactus (Opuntia stricta) is another plant that
is especially well adapted to this environment. In order to minimize
water loss, the leaves are reduced to spines and the stems are modified
into pads that store water. Many scrub species have roots that reach the
water table or which spread along the surface of the soil, in order to
capture water before it percolates into the ground.
