Fig. 8. In the WUCOLS IV list, plants are identified by vegetation type. For example, the symbol for bamboo is "Ba."
The WUCOLS list includes over 3,546 entries of landscape plants (species, cultivars, and hybrids) that are identified by botanical and common names. The plants are listed alphabetically according to botanical names.

Each plant falls into one or more of the following vegetation types, shown with a corresponding symbol (Fig. 8).

If a plant is considered to have more than one vegetation type (e.g., it has both tree and shrub forms), it is identified as such.

Turfgrass Species

Turfgrass species were not evaluated by the regional committees. Water requirements for turf species are given in Appendix <1>. Water use requirements are taken from Managing Turfgrass During Drought (University of California ANR Publication 8395). This publication also contains other important information regarding turfgrass irrigation, such as plant performance at varying irrigation levels, drought resistance, and rooting depths of species.
