  • Conifer Communities of the Santa Cruz Mountains and Interpretive
    UNIVERSITY OF CALIFORNIA, SANTA CRUZ CALIFORNIA CONIFERS: CONIFER COMMUNITIES OF THE SANTA CRUZ MOUNTAINS AND INTERPRETIVE SIGNAGE FOR THE UCSC ARBORETUM AND BOTANIC GARDEN A senior internship project in partial satisfaction of the requirements for the degree of BACHELOR OF ARTS in ENVIRONMENTAL STUDIES by Erika Lougee December 2019 ADVISOR(S): Karen Holl, Environmental Studies; Brett Hall, UCSC Arboretum ABSTRACT: There are 52 species of conifers native to the state of California, 14 of which are endemic to the state, far more than any other state or region of its size. There are eight species of coniferous trees native to the Santa Cruz Mountains, but most people can only name a few. For my senior internship I made a set of ten interpretive signs to be installed in front of California native conifers at the UCSC Arboretum and wrote an associated paper describing the coniferous forests of the Santa Cruz Mountains. Signs were made using the Arboretum’s laser engraver and contain identification and collection information, habitat, associated species, where to see local stands, and a fun fact or two. While the physical signs remain a more accessible, kid-friendly format, the paper, which will be available on the Arboretum website, will be more scientific with more detailed information. The paper will summarize information on each of the eight conifers native to the Santa Cruz Mountains including localized range, ecology, associated species, and topics pertaining to the species in current literature. KEYWORDS: Santa Cruz, California native plants, plant communities, vegetation types, conifers, gymnosperms, environmental interpretation, UCSC Arboretum and Botanic Garden I claim the copyright to this document but give permission for the Environmental Studies department at UCSC to share it with the UCSC community.

  • California Buckeye Hippocastanaceae Aesculus Californica
    The Watershed Nursery www.thewatershednursery.com California buckeye Hippocastanaceae Aesculus californica Sun: Full Sun, Part Shade, Shade Water: Dry, Light, Moderate, High Soil: Clay, Loam, Sand, Rocky Other: Attracts Butterflies, Attracts Birds, Drought Tolerant, Erosion Control Ecological Value: It's shallow spreading roots make this tree an excellent slope stabilizer. Many native insects, including native bees, use it as a nectar source. When there is no other nectar source, high concentrations of buckeye nectar can be poisonous to honeybees. Historical Uses: Many California native groups considered the seeds of the buckeye to be a backup food crop in times when acorn harvests were lean. Leaves, new shoots, and seeds could were used as a fish poison and the wood provided a fast growing source of material for constructing shelters and various tools. Native Distribution: Endemic to California. Elevation: In the Garden Between 0 and 4000 feet This drought tolerant deciduous tree grows 15 to 30'. Plant Communities: Foothill woodlands California buckeye provides year-round beauty to the garden. During the dormant season, the handsome, thick-stemmed silhouette and silvery smooth bark is revealed. Apple green foliage bursts Habitat: forth in early spring. Beautifully abundant Foothill Woodland in dry canyons and slopes candelabra like flowers bloom from April -June and visited by nectar seeking hummingbirds. If that isn't enough, large chestnut-brown seeds then appear in the fall. Use as a single specimen in the landscape or plant several as an informal hedge. This plant combines well with evergreens such as coast live oak and California bay. Little pruning needed..

  • Aesculus Californica (Family: Sapindaceae) Common Names: California Buckeye, California Horse-Chestnut
    Aesculus californica (Family: Sapindaceae) Common Names: California Buckeye, California Horse-chestnut Taxonomic Description: The California Buckeye is a large native, deciduous shrub or tree that is recognized by its broad, round shape and gray bark usually with a moss or lichen coating. The entire tree can grow between 10 to 25 feet tall (about 12 meters). Its compound leaves grow in leaflets of 5 that range from 5 to 17 centimeters and petiole from 1 to 12 centimeters. The leaves are tender to protect from severe weather damaging. This tree is the first to grow leaves in the spring, the last to bloom, and the first to lose its leaves. Flowers of the California Buckeye are grown from erect panicles; they smell sweet and are colored from white to pale pink. Fruits of this tree are capsules from 5 to 8 centimeters long, shaped as figs. Inside these fruits are smooth, round, 2 to 5 centimeters big orange- brown seeds that are poisonous. Growth Form/Habitat/Soil: The California Buckeye is adapted to coarse textured soils and medium textured soils for growth. It has no anaerobic tolerance and low CaCO3 tolerance, high drought tolerance and medium fire tolerance and water use. A pH minimum of 5.5 pH, and a maximum of 7.5 pH in the soil is required. Because the trees are able to grow in crowded, or moist, or even semi-shaded environments, they can commonly be found on dry hills, canyon slopes, and borders of streams. Distribution (geographic): The California Buckeye is native to the state, and is widely distributed within it.

  • Umbdlularia Californica (Hook. & Am.) Nutt. California-Laurel
    Umbdlularia californica (Hook. & Am.) Nutt. California-Laurel Lauraceae Laurel family William I. Stein California-laurel (UmbeZZuZaria californica) is the most valued and best publicized hardwood species in '450 the Western United States. It is a monotypic, broad- --IL leaved evergreen with many common names, includ- ing bay, laurel, California-bay, Oregon-myrtle, myrtlewood, Pacific-myrtle, spice-tree, and pepper- wood (50). The names are derived from leaf, fruit, or wood characteristics and also from some similarities often mistaken for relationships with the myrtle and laurel trees of the Mediterranean area (12,25). Decorative items made from the hard, beautifully grained wood are widely marketed as myrtlewood. Habitat Native Range The range of California-laurel (fig. 1) spans more than 11” of latitude, from below the 44th parallel in the Umpqua River Valley of Douglas County, OR, south beyond the 33d parallel in San Diego County, CA. In the Coast Ranges, the southern limit is on eastern slopes of the Laguna Mountains, a short dis- tance from the Mexican border (19). In the Sierra Nevada, it extends as far south as the west slope of Breckenridge Mountain in Kern County (58). Eastward from the coast, California-laurel extends to the foothills of the Cascade Range in Oregon and California, into the western Sierra Nevada for its entire length, and to the inland side of the Coast Ranges south of San Luis Obispo, CA. Its farthest extent inland, about 257 km (160 mi), is in the southern Sierra Nevada. Climate California-laurel grows in diverse climates, rang- ing from the cool, humid conditions found in dense -300 coastal forests to the hot, dry atmospheres found # inland in open woodlands and chaparral.

  • Southern California Oak Woodland Habitats
    Southern California Oak Woodland Habitats Climate Change Vulnerability Assessment Synthesis An Important Note About this Document: This document represents an initial evaluation of vulnerability for oak woodland habitats based on expert input and existing information. Specifically, the information presented below comprises habitat expert vulnerability assessment survey results and comments, peer- review comments and revisions, and relevant references from the literature. The aim of this document is to expand understanding of habitat vulnerability to changing climate conditions, and to provide a foundation for developing appropriate adaptation responses. Executive Summary As defined by the California Wildlife Habitat Relationships System (CWHR), the southern California study region contains primarily coastal oak woodlands and montane hardwoods, with coast live oak dominating the former (CWHR 2015a), and black oak and canyon live oak dominating the latter (CWHR 2015b). Engelmann oak, interior live oak, scrub oak, and other species can Photo by Noah Elhardt (Public Domain) co-occur with these dominants in oak canopies (Bartolome 1987; CWHR 2015a, 2015b, 2015c, 2015d), and many oak species occur as sub- dominants in other habitat types (Los Angeles County 2011). The northern zones of the study area also contain blue oak and valley oak woodlands, which reach the southern end of their distribution in this region (CWHR 2015c, 2015d; Hoagland et al. 2011; Plumb and McDonald 1981). As dominant canopy species, oaks create favorable microclimates for diverse understory vegetation and provide habitat for many wildlife species (Howard 1992; Tietje et al. 2005; Verner 1987). The relative vulnerability of oak woodland habitats in southern California was evaluated to be low-moderate1 by habitat experts due to low-moderate sensitivity to climate and non-climate stressors, low-moderate exposure to projected future climate changes, and moderate adaptive capacity.

  • ABSTRACT the First Through Fifth Instars of the Gypsy Moth Were Tested for Development to Adults on 326 Species of Dicotyledonous Plants in Laboratory Feeding Trials
    LABORATORY FEEDING TESTS ON THE DEVELOPMENT OF GYPSY MOTH LARVAE WITH REFERENCE TO PLANT TAXA AND ALLELOCHEMICALS JEFFREY C. MILLER and PAUL E. HANSON DEPARTMENT OF ENTOMOLOGY, OREGON STATE UNIVERSITY, CORVALLIS, OREGON 97331 ABSTRACT The first through fifth instars of the gypsy moth were tested for development to adults on 326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants, differences in suitability were documented by measuring female pupal weights. The majority of accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and Rosidae. Species of oak, maple, alder, madrone, eucalyptus, poplar, and sumac were highly suitable. Plants belonging to the Asteridae, Caryophyllidae, and Magnoliidae were mostly rejected. Foliage type, new or old, and instar influenced host plant suitability. Larvae of various instars were able to pupate after feeding on foliage of 147 plant species. Of these, 1.01 were accepted by first instars. Larvae from the first through fifth instar failed to molt on foliage of 151 species. Minor feeding occurred on 67 of these species. In general, larvae accepted new foliage on evergreen species more readily than old foliage. The results of these trials were combined with results from three previous studies to provide data on feeding responses of gypsy moth larvae on a total of 658 species, 286 genera, and 106 families of dicots. Allelochemic compositions of these plants were tabulated from available literature and compared with acceptance or rejection by gypsy moth. Plants accepted by gypsy moth generally contain tannins, but lack alkaloids, iridoid monoterpenes, sesquiterpenoids, diterpenoids, and glucosinolates. 2 PREFACE This research was funded through grants from USDA Forest Service cooperative agreement no.
