APPENDIX F GLOSSARY
| Candidate species | Species being reviewed by the U.S. Fish and Wildlife Service for possible listing as endangered or threatened, but for which substantial biological information to support a listing is lacking. |
| Critical habitat | "Specific areas within the geographical area occupied by [an endangered or threatened] species . . . , essential to the conservation of the species and which may require special management considerations or protection; and specific areas outside the geographical area occupied by the species . . . that are essential for the conservation of the species" (Endangered Species Act section 3). |

| Endangered species | Species of plants and animals that are threatened with either extinction or serious depletion in their range and that are formally listed as such by the U.S. Fish and Wildlife Service. |
| Eutrophic | Rich in dissolved nutrients. |
| Explosives | See High explosives. |
| Feral | Escaped from domestication and became wild. |
| Forbs | Herbs other than grasses. |
| Half-life | Time required for a radioactive substance to lose 50 percent of its activity by decay. |
| High explosives (HE) | Chemically energetic materials with the potential to react explosively; nuclear explosives are not included. |
| Hydrodynamic testing | Testing the properties of solid materials or the behavior of components made of such materials by subjecting them to strong shock from explosives or high-velocity impact. |
| Kit fox biologist | See Trained kit fox biologist. |
| Lagomorphs | Rabbits, conies, and hares. |
| Phenologic period | Period during the year when characteristic activities take place, such as (for vegetation) flowering and fruiting. |
| Relevé | A descriptive technique for sampling vegetation. |
| Riparian | Located along the banks of a stream, rivers, lakes, and other bodies of water. |
| Scat | Animal droppings, feces. |
| Taxon (pl: taxa) | The name applied to a plant or animal group in a formal system of nomenclature. |
| Threatened species | A species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. |
| Trained kit fox biologist | A trained kit fox biologist must have at least four years of college or university training in wildlife biology or a related field, and have demonstrated field expertise in the identification and life history of the San Joaquin kit fox. |
| Transect | A sample area (as of vegetation), usually in the form of a long continuous strip. |
| Vascular plants | Plants characterized by channels or ducts for the transfer of sap upward from the roots to their above-ground growing portions. |
| Vernal pool | A wetland created from standing water, typically in the spring, hence its name. |
