Botany BA/BE Lehigh Southwest Land Exchange FINAL

I. PROJECT DESCRIPTION

The Shasta-Trinity National Forest (STNF) proposes to exchange lands with Lehigh Southwest Cement Company (Lehigh) and approve a non-significant amendment to the STNF Land and Resource Management Plan (U.S. Forest Service 1994). The lands to be exchanged include two Federal parcels managed by the Forest Service near the Gray Rocks quarry on the south side of Shasta Lake east of Interstate 5, encompassing approximately 62.56 acres, and one private parcel owned by Lehigh on the east side of Shasta Lake at the McCloud River arm, encompassing up to approximately 243.94 acres (specific acreage to be determined during land appraisal). Easements on Road 33N99 would also be exchanged as part of the land transfer to maintain access for each party across the lands. The lands and Road 33N99 are in the Shasta Unit of the Whiskeytown-Shasta-Trinity National Recreation Area on the STNF in Shasta County, California. The purpose of the exchange from private to Federal ownership is to consolidate National Forest ownership of lands in the Shasta Unit of the NRA and protect high quality plant and wildlife habitat along the McCloud River arm of Shasta Lake. A complete description of the purpose and need and alternatives can be found in the Environmental Assessment (see project record).

II. AFFECTED ENVIRONMENT

The project area is characterized by a variety of vegetation types typical of transitional mixed woodland and low-elevation forest habitats. The L-shaped Federal parcel (easternmost Federal parcel) is dominated by ponderosa pine, with some mixed chaparral on the west side. The westernmost Federal parcel contains blue oak-foothill pine, mixed chaparral, montane hardwood- conifer, montane hardwood, ponderosa pine, and Sierran or Klamath mixed conifer. The elevation range of the L-shaped parcel is 1,200 to 1,800 feet above mean sea level, and the elevation range of the other Federal parcel is 1,400 to 2,000 feet above mean sea level. Both Federal parcels are currently used to support mining operations at Gray Rocks mine. The westernmost parcel is more disturbed and contains a road and mining-related facilities; the L- shaped parcel is less disturbed with limited access. Habitats on the private parcel include mixed chaparral, montane hardwood, montane hardwood- conifer, Sierran mixed conifer, and montane riparian. The understories of these habitats range from open to dense and have varying species composition. Several intermittent and ephemeral streams traverse the parcel. The elevation range of the parcel is from about 1,200 to 2,400 feet above mean sea level. The parcel is currently inaccessible to the public, and few roads provide access in the vicinity of the parcel, resulting in no current active uses.

III. RARE PLANT ANALYSES Introduction to Plant Species Analysis This Biological Assessment/Biological Evaluation (BA/BE) was prepared to inform the decision makers and disclose the likely effects of the proposed action on federally listed plant species (endangered, threatened, and proposed); Region 5 Forest Service Sensitive plant, lichen, and

1 Lehigh Southwest Land Exchange Botany BA/BE FINAL

fungi species (FSM 2670.31-2670.32); and Forest Endemic species that receive the same management protections as Sensitive species (U.S. Forest Service 1994). A list of species considered in this BA/BE was derived from the U.S. Fish and Wildlife Service online list of species that may occur in the Project City and O’Brien 7.5-minute quadrangles (December 4, 2012) and the Forest Service list of Threatened, Endangered, Proposed, Sensitive, and Endemic species that are known to occur or may occur on the STNF (last updated February 2012). A comprehensive list of species considered is provided in Appendix A.

Biological Assessment for Threatened/Endangered/Proposed Species Two plant species listed under the Endangered Species Act may occur on the STNF: Water howellia (Howellia aquatilis) is a threatened species and a Forest Service Sensitive species. It is found in freshwater marshes and swamps in mixed conifer forests and is only known from Mendocino County in California, with most populations occurring in Washington, Idaho, and Montana (U.S. Fish and Wildlife Service 1996). Critical habitat has not been designated for water howellia. Slender Orcutt grass (Orcuttia tenuis) is a threatened species and a Forest Service Sensitive species. It is restricted geographically to the Sacramento Valley and surrounding areas, Shasta and Tehama counties primarily, and is also found in Sacramento and Lake counties, California, where it inhabits vernal pools with a very well developed soil profile. O. tenuis prefers clay soils that shrink and swell. As they dry, large cracks develop that allow seeds trapped deeply in the soil to float to the surface with the first inundation. Critical habitat has been designated for slender Orcutt grass (U.S. Fish and Wildlife Service 2006). The project area is not in the known geographic range of water howellia, and the species is not expected to occur. The project area does not contain suitable habitat for slender Orcutt grass because of the lack of vernal pools, and designated critical habitat units for slender Orcutt grass do not overlap the project area. No further analysis is required for species that are not known or suspected to occur in the project area and for which no suitable habitat is present. Neither federally listed species is considered further in this document.

Biological Evaluation for Region 5 Sensitive Species The following table identifies the Region 5 Sensitive and Endemic plant, lichen, and fungi species that might occur within the project area. Two Forest Endemics are included in the Sensitive species analysis because the STNF LRMP dictates that these species be treated as if they were Sensitive. See Appendix A for the complete list of Sensitive and Endemic plants, lichens, and fungi considered in this project analysis.

Potential effects are evaluated if suitable but unoccupied habitat is present. The project area is in the known range of the species listed in Table 1, and suitable habitat is present for each of the species. Other species listed in Appendix A are not considered further in this document. A survey of the Federal parcels was conducted on May 15, 2012 by the STNF District Botanist and three others, but no populations of any of the above species were found. Portions of the project area and adjacent lands have also been subject to botanical and biological surveys associated with other projects within the past 10 years. Botanical surveys of the Shasta Lake shoreline have been done in recent years by the U.S. Bureau of Reclamation as part of the Shasta Lake Water Resources Investigation and of the STNF around Shasta Lake by the Forest Service as part of various projects. Rare plant locations from most of these surveys have been documented in the California Natural Diversity Database and have been made available by the

3 Lehigh Southwest Land Exchange Botany BA/BE FINAL

Forest Service. Most of the project area and adjacent private lands have been surveyed by North State Resources (NSR), which included incidental observations of special-status plant species and focused surveys for certain species (e.g., Shasta snow-wreath). The private parcel was surveyed by NSR and LSA Associates, Inc. to delineate wetlands and other waters of the United States, which included recording observed plant species (LSA 2005). None of the species listed in Table 1 has been documented in the project area; however, focused surveys for all of the species have not been conducted on all of the parcels. Populations of the species could be present in portions of the project area that have not been subject to focused surveys based on the presence of suitable habitat and known occurrences nearby. No new ground-disturbing activities or facility modifications are proposed. Federal management of the currently private lands along the McCloud River arm would not alter uses of the land or involve activities that could disturb Sensitive or Endemic plant populations, if present, or the species’ habitats. The Forest Service would acquire up to 244 acres of habitat that may be suitable for some or all of the Sensitive and Endemic species listed in Table 1. Once the Federal lands are transferred to private ownership, they would continue to be used for mining-related activities, but ongoing activities would continue to be restricted to previously disturbed areas. The Forest Service would relinquish management of the parcels, and approximately 58 acres of habitat (excluding barren/disturbed areas) for Sensitive and Endemic species would be transferred out of Federal ownership.

Analysis of Cumulative Effects to Region 5 Sensitive Plant Species Cumulative effects are described as the effects of the action when added to past, ongoing, or reasonably foreseeable actions (36 CFR § 220.4 (f) of 07/24/08). The proposed land exchange would not contribute to cumulative effects on any of the Sensitive or Endemic plants listed in Table 1 because no new habitat disturbance or facility modifications are proposed. The project involves land transfers between the Forest Service and Lehigh, which would only change management of the land and its resources, and the uses of the land would continue as they currently are.

IV. DETERMINATIONS

The biological determination for the following Region 5 Sensitive or Endemic plant species is no effect, and the proposed action would not contribute to a trend towards Federal listing or loss of viability to the population or species: • Ageratina shastensis, Shasta eupatory • Arnica venosa, Shasta County arnica • Calystegia atriplicifolia ssp. buttensis, Butte County morning glory • Clarkia borealis ssp. borealis, northern clarkia • Fritillaria eastwoodiae, Butte County fritillary • Lewisia cantelovii, Cantelow’s lewisia • Neviusia cliftonii, Shasta snow-wreath • Sedum paradisum, Canyon Creek stonecrop

Rationale for Determination Ageratina shastensis, Shasta eupatory: Shasta eupatory is known to occur along the McCloud River arm of Shasta Lake and north of the lake. The nearest occurrences are about 2 miles northwest of the private parcel at Hirz Mountain and 5.5 miles southwest of the private parcel near Shasta Caverns (occurrences re-verified in 2010) (CDFG 2012). No observations of the species were documented by NSR during surveys of the private parcel in 2005 or of the Federal parcels in 2006. Rock outcrops are present on the Federal and private parcels, and Shasta eupatory may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated. Arnica venosa, Shasta County arnica: Shasta County arnica is known to occur around Shasta Lake. The nearest occurrence is about 1 mile west of the Federal parcels along the southern shore of the lake, which was recorded during recent surveys associated with the Shasta Lake Water Resources Investigation (NSR 2011). No observations of the species were documented by NSR during surveys of the private parcel in 2005 or of the Federal parcels in 2006. Mixed conifer forest is present on the Federal and private parcels, and Shasta County arnica may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated. Calystegia atriplicifolia ssp. buttensis, Butte County morning glory: Butte County morning glory is known to occur along the Pit River and its tributaries. The nearest occurrences are more than 10 miles east of the private parcel and include observations made during the 1930s (CDFG 2012). No observations of the species were documented by NSR during surveys of the private parcel in 2005 or of the Federal parcels in 2006. Chaparral and lower montane coniferous forest are present on the Federal and private parcels, and Butte County morning glory may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated. Clarkia borealis ssp. borealis, Northern clarkia: Northern clarkia is known to occur around Shasta Lake and is restricted to Shasta County and immediately adjacent areas in Siskiyou and Trinity counties. The nearest recent occurrence is about 3.5 miles north of the Federal parcels along the McCloud River arm, which was recorded during recent surveys associated with the Shasta Lake Water Resources Investigation (NSR 2011). Several other occurrences have been documented within 3 miles of the private parcel and just south of the Federal parcels, but these observations were made in the 1930s (CDFG 2012). No observations of the species were documented by NSR during surveys of the private parcel in 2005 or of the Federal parcels in 2006. Foothill woodlands and forest margins are present on the Federal and private parcels, and northern clarkia may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated.

5 Lehigh Southwest Land Exchange Botany BA/BE FINAL

Fritillaria eastwoodiae, Butte County fritillary: Butte County fritillary is known to occur along the Pit River and Squaw Creek, but has not been documented west of the Squaw Creek arm of Shasta Lake. The nearest occurrences are more than 4 miles east of the private parcel (CDFG 2012). Several observations of the species were made along Squaw Creek, Ripgut Creek, and Flat Creek during recent surveys by the Forest Service (NSR 2011). No observations of the species were documented by NSR during surveys of the private parcel in 2005 or of the Federal parcels in 2006. Chaparral, cismontane woodland, and lower montane coniferous forest are present on the Federal and private parcels, and Butte County fritillary may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated. Lewisia cantelovii, Cantelow’s lewisia: Cantelow’s lewisia is known to occur on rock outcrops near the Sacramento River arm of Shasta Lake. Four observations of the species were made along the Sacramento River arm during recent surveys associated with the Shasta Lake Water Resources Investigation (NSR 2011). Several other occurrences have been documented along the Sacramento River above the lake, but these observations were made in the 1970s (CDFG 2012). Rock outcrops in woodlands and coniferous forests are present on the Federal and private parcels, and Cantelow’s lewisia may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated. Neviusia cliftonii, Shasta snow-wreath: Shasta snow-wreath is known to occur around Shasta Lake, including along the McCloud River arm. Several occurrences were documented along the McCloud River arm and the southern side of the lake in the 1990s (CDFG 2012). An estimated 23 populations of the snow-wreath have been documented during recent surveys associated with the Shasta Lake Water Resources Investigation, with about half of these along the McCloud and Pit River arms of the lake and along Squaw Creek (NSR 2011). Cismontane woodland and lower montane coniferous forest are present on the Federal and private parcels, although limited riparian woodland is present (some on the private parcel, but none on the Federal parcels), and Shasta snow-wreath may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated. Sedum paradisum, Canyon Creek stonecrop: Canyon Creek stonecrop is known to occur west of Shasta Lake near Trinity Lake. Two occurrences have been documented west of Shasta Lake along tributaries to Clear Creek, and these observations were recorded in 1980 (CDFG 2012). Rock outcrops in woodlands and coniferous forests are present on the Federal and private parcels, and Canyon Creek stonecrop may occur. No activities are proposed that would result in new ground disturbance or potential impacts on populations of the species or its habitat; therefore, no effects are anticipated.
