APPENDIX J
NATIVE & INVASIVE PLANT LIST
The following tables capture the referenced plants, native and invasive species, found throughout this
document. The Wildlife Action Plan Team elected to only use common names for plants to improve the
readability, particular for the general reader. However, common names can create confusion for a variety of
reasons. Common names can change from region-to-region; one common name can refer to more than one
species; and common names have a way of changing over time. For example, there are two widespread species
of greasewood in Nevada, and numerous species of sagebrush. In everyday conversation generic common
names usually work well. But if you are considering management activities, landscape restoration or the habitat
needs of a particular wildlife species, the need to differentiate between plant species and even subspecies
suddenly takes on critical importance. This appendix provides the reader with a cross reference between the
common plant names used in this document’s text, and the scientific names that link common names to the
precise species to which writers referenced.
With regards to invasive plants, all species listed under the Nevada Revised Statute 555 (NRS 555) as a “Noxious
Weed” will be notated, within the larger table, as such. A noxious weed is a plant that has been designated by
the state as a “species of plant which is, or is likely to be, detrimental or destructive and difficult to control or
eradicate” (NRS 555.05). To assist the reader, we also included a separate table detailing the noxious weeds,
category level (A, B, or C), and the typical habitats that these species invade.
