Endangered and Threatened Wildlife and Plants; 12-Month Finding on a Petition To List Agave eggersiana and Solanum conocarpum as Endangered
We, the Fish and Wildlife Service (Service), announce a 12- month finding on a petition to list the plants Agave eggersiana (no common name) and Solanum conocarpum (marr[oacute]n bacora) as endangered under the Endangered Species Act of 1973, as amended (Act). After reviewing the best available scientific and commercial information, we find that listing A. eggersiana and S. conocarpum is not warranted at this time. However, we will continue to seek new information on the biology of these species as well as potential threats. We also ask the public to submit to us any new information that becomes available concerning the status of, or threats to, A. eggersiana and S. conocarpum. This information will help us monitor the status of these species. If additional data become available, we may reassess the need for listing.
Recovery Plan for Vernal Pool Ecosystems of California and Southern Oregon
We (the U.S. Fish and Wildlife Service) announce the availability of the Recovery Plan for Vernal Pool Ecosystems of California and Southern Oregon. This recovery plan covers 33 species, of which 20 are federally listed as threatened or endangered. These species inhabit vernal pool ecosystems in California and southern Oregon. This recovery plan includes recovery criteria and measures for 20 federally listed species. Federally endangered plants include Eryngium constancei (Loch Lomond button-celery), Lasthenia conjugens (Contra Costa goldfields), Limnanthes floccosa ssp. californica (Butte County meadowfoam), Navarretia leucocephala ssp. pauciflora (few- flowered navarretia), Navarretia leucocephala ssp. plieantha (many- flowered navarretia), Orcuttia pilosa (hairy Orcutt grass), Orcuttia viscida (Sacramento Orcutt grass), Parvisedum leiocarpum (Lake County stonecrop), Tuctoria greenei (Greene's tuctoria), and Tuctoria mucronata (Solano grass). Federally threatened plants include Castilleja campestris ssp. succulenta (fleshy owl's clover), Chamaesyce hooveri (Hoover's spurge), Neostapfia colusana (Colusa grass), Orcuttia inaequalis (San Joaquin Valley Orcutt grass), and Orcuttia tenuis (slender Orcutt grass). Federally endangered animals include the Conservancy fairy shrimp (Branchinecta conservatio), longhorn fairy shrimp (Branchinecta longiantenna), and vernal pool tadpole shrimp (Lepidurus packardi). Federally threatened animals include the vernal pool fairy shrimp (Branchinecta lynchi) and delta green ground beetle (Elaphrus viridis). The portions of the plan dealing with the delta green ground beetle and Solano grass are a revision of the 1985 Delta Green Ground Beetle and Solano Grass Recovery Plan. The recovery plan addresses conservation of 10 plant species of concern, including Astragalus tener var. ferrisiae (Ferris' milk vetch), Astragalus tener var. tener (alkali milk vetch), Atriplex persistens (persistent-fruited saltscale), Eryngium spinosepalum (spiny-sepaled button-celery), Gratiola heterosepala (Boggs Lake hedge- hyssop), Juncus leiospermus var. ahartii (Ahart's dwarf rush), Legenere limosa (legenere), Myosurus minimus var. apus (little mouse tail), Navarretia myersii ssp. deminuta (pincushion navarretia), and Plagiobothrys hystriculus (bearded popcorn flower). The three animal species of concern addressed in the recovery plan include the mid- valley fairy shrimp (Branchinecta mesovallensis), California fairy shrimp (Linderiella occidentalis), and western spadefoot toad (Spea hammondii).
