Categories accommodate plant species that are classified as having more than one plant form (see<br />
Appendix J).<br />
Not including grasses.<br />
Over the years, over 850 plant species have been identified on <strong>Camp</strong> <strong>Pendleton</strong> (Table 3-<br />
4). A comprehensive plant list is presented in Appendix J. Included in that list are<br />
numerous rare plant species (see Section 3.2.2.2.) and three federally listed threatened or<br />
endangered plant species: thread-leaved brodiaea (Brodiaea filifolia), spreading navarretia<br />
(Navarretia fossalis), and San Diego button-celery (Eryngium aristulatum var. parishii)<br />
(see Appendix F for detailed information of each federally listed species on <strong>Camp</strong><br />
<strong>Pendleton</strong>).<br />
Most of the plants on <strong>Base</strong> are considered native to the region, but as many as 22% (Table<br />
3-4) are exotic (nonnative), often invasive species that were introduced during the period of<br />
European settlement. These nonnative species are believed to have displaced some native<br />
plant species in the region.<br />
Some of the exotic invasive plant species that occur on <strong>Base</strong> include giant reed grass<br />
(Arundo donax), artichoke thistle (Cynara cardunculus), perennial pepperweed (Lepidium<br />
latifolium), mustard (Brassica spp.) fennel (Foeniculum vulgare), ice plant<br />
(Mesembryanthemum crystallinum, Carpobrotos spp. and Aptenia spp.), tamarisk (Tamarix<br />
parviflora), and tree tobacco (Nicotiana glauca). As additional invasive exotic species are<br />
identified, control and management activities are initiated. New additions to managed<br />
exotic invasive plant species since 2001 include bridal veil broom (Retama monosperma),<br />
scotch broom (Cytisus scoparius), yellow starthistle (Cenaurea solstitialis), and cape ivy<br />
(Delairea odorata).<br />
