A CHECKLIST OF THE VASCULAR PLANTS OF THE TRINITY ALPS (NORTHWESTERN CALIFORNIA) Compiled by James P. Smith, Jr. Professor Emeritus of Botany Department of Biological Sciences Humboldt State University Third Edition • 17 April 2019 INTRODUCTION LYCOPHYTES (FERN ALLIES) The Trinity Alps are a mountain range located about 50 miles ISOËTACEAE • Quillwort Family northwest of Redding in Trinity and Siskiyou counties, California. Isoëtes bolanderi • Bolander’s quillwort They are a component of the Klamath Mountains, and as such lie Isoëtes howellii • Howell’s quillwort between the Coast Range to the west and the Cascade Range to the Isoëtes tenella • Spiny-spored quillwort east.

Factors found to favor seedling establishment were abundance of sound seed, mineral soil seedbed, and probably some shade in the first year. Chief obstacles to seedling survival and growth included strong insolation, deep litter, insects, competing low vegetation, and time between good seed years. The most practical approach to securing natural regeneration appears to be keeping abundant seed trees close to a prepared mineral soil seedbed.

    APPENDIX I Botany Biological Evaluation Biological Evaluation for Threatened, Endangered and Sensitive Plants and Fungi Page 1 of 35 for the Upper Truckee River Sunset Stables Restoration Project November 2009 UNITED STATES DEPARTMENT OF AGRICULTURE – FOREST SERVICE LAKE TAHOE BASIN MANAGEMENT UNIT Upper Truckee River Sunset Stables Restoration Project El Dorado County, CA Biological Evaluation for Threatened, Endangered and Sensitive Plants and Fungi PREPARED BY: ENTRIX, Inc. DATE: November 2009 APPROVED BY: DATE: _____________ Name, Forest Botanist, Lake Tahoe Basin Management Unit SUMMARY OF EFFECTS DETERMINATION AND MANAGEMENT RECOMMENDATIONS AND/OR REQUIREMENTS One population of a special-status bryophyte, three-ranked hump-moss (Meesia triquetra), was observed in the survey area during surveys on June 30, 2008 and August 28, 2008. The proposed action will not affect the moss because the population is located outside the project area where no action is planned. The following species of invasive or noxious weeds were identified during surveys of the Project area: cheatgrass (Bromus tectorum); bullthistle (Cirsium vulgare); Klamathweed (Hypericum perforatum); oxe-eye daisy (Leucanthemum vulgare); and common mullein (Verbascum Thapsus). The threat posed by these weed populations would not increase if the proposed action is implemented. An inventory and assessment of invasive and noxious weeds in the survey area is presented in the Noxious Weed Risk Assessment for the Upper Truckee River Sunset Stables Restoration Project (ENTRIX 2009). Based on the description of the proposed action and the evaluation contained herein, we have determined the following: There would be no significant effect to plant species listed as threatened, endangered, proposed for listing, or candidates under the Endangered Species Act of 1973, as amended (ESA), administered by the U.S.

Three ways to contact us: FAX: (303) 621-2864 (24 HRS.) email: [email protected] website: www.alplains.com Dear Growing Friends: Welcome to our 23rd annual seed catalog! The summer of 2012 was long, hot and brutal, with drought afflicting most of the U.S. Most of my botanical explorations were restricted to Idaho, Wash- ington, Oregon and northern California but even there moisture was below average. In a year like this, seeps, swales, springs, vestigial snowbanks and localized rainstorms became much more important in my search for seeding plants. On the Snake River Plains of southern Idaho and the scab- lands of eastern Washington, early bloomers such as Viola beckwithii, V. trinervata, Ranunculus glaberrimus, Ranunculus andersonii, Fritillaria pudica and Primula cusickiana put on quite a show in mid-April but many populations could not set seed. In northern Idaho, Erythronium idahoense flowered extensively, whole meadows were covered with thousands of the creamy, pendant blossoms. One of my most satisfying finds in the Hells Canyon area had to be Sedum valens. The tiny glaucous rosettes, surround- ed by a ring of red leaves, are a succulent connoisseur’s dream. Higher up, the brilliant blue spikes of Synthyris missurica punctuated the canyon walls. In southern Oregon, the brilliant red spikes of Pedicularis densiflora lit up the Siskiyou forest floor. Further north in Oregon, large populations of Erythronium elegans, Erythronium oregonum ssp. leucandrum, Erythro- nium revolutum, trilliums and sedums provided wonderful picture-taking opportunities. Eriogonum species did well despite the drought, many of them true xerics.

The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks.

The area was nominated by the National Forest as a candidate RNA in 1986 to preserve an example of the Sierra Nevada mixed conifer forest for the South Coast Range Province. The RNA as defined in this report covers 2963 acres (1199 ha). The boundaries differ from those originally proposed by the National Forest (map 5, and see discussion of boundaries in later section).

  • Hybridization of the California Firs
    Forest Science, Vol. 34, No. I, pp. 139-151. Copyright 1988 by the Society of American Foresters Hybridization of the California Firs William B. Critchfield Abstract. Four groups of firs (sections, in the most recent classification of Abies) are represented in California. Crossing within these sections is possible and even easy, and in two of the sections intergrading populations between highly crossable taxa are wide spread in California. An exception is A. amabilis, a Northwestern fir that has not been crossed with other species in the same section {Grandes: A. concolor, A. grandis) or in other sections (e.g., Nobiles: A magnified). Crossing species in different sections is usually difficult or impossible. The genetic isolation of A. bracteata, an endemic species classified as a monotypic subgenus or section, may be nearly complete: two probable hybrids with A. concolor died at a few years of age. A few putative hybrids from inter- sectional crosses between species in Grandes and Nobiles died within months of germi nation. Intersectional crosses with firs outside California (two Mexican and four Eur asian species) all failed except A. concolor x A. religiosa, which produced numerous healthy hybrids. The common occurrence of genetic barriers in Abies is at odds with the long-held view that it is easy to hybridize fir species. For. Sci. 34(1): 139-151. Additional key words. Abies, interspecific hybrids, crossability, classification. The ability of species to hybridize has not been explored as systemati cally in the genus Abies (true firs) as it has in other genera of Pinaceae such as Pinus and Pice a.
