  • Soil Heterogeneity and the Distribution of Native Grasses in California: Can Soil Properties Inform Restoration Plans? 1, KRISTINA M
    Soil heterogeneity and the distribution of native grasses in California: Can soil properties inform restoration plans? 1, KRISTINA M. HUFFORD, SUSAN J. MAZER, AND JOSHUA P. S CHIMEL Ecology, Evolution and Marine Biology, University of California, Santa Barbara, California 93106 USA Citation: Hufford, K. M., S. J. Mazer, and J. P. Schimel. 2014. Soil heterogeneity and the distribution of native grasses in California: Can soil properties inform restoration plans? Ecosphere 5(4):46. http://dx.doi.org/10.1890/ES13-00377.1 Abstract. When historical vegetation patterns are unknown and local environments are highly degraded, the relationship between plant species distributions and environmental properties may provide a means to determine which species are suitable for individual restoration sites. We investigated the role of edaphic variation in explaining the distributions of three native bunchgrass species (Bromus carinatus, Elymus glaucus and Nassella pulchra) among central California mainland and island grasslands. The relative contribution of soil properties and spatial variation to native grass species abundance was estimated using canonical redundancy analysis, with subsequent testing of individual variables identified in ordination. Soil variables predicted a significant proportion (22–27%) of the variation in species distributions. Abiotic soil properties that drive species distributions included serpentine substrates and soil texture. Biotic properties that correlated with species distributions were ammonium and nitrogen mineralization rates. Spatial autocorrelation also contributed to species presence or absence at each site, and the significant negative autocorrelation suggested that species interactions and niche differentiation may play a role in species distributions in central California mainland and island grasslands. We explored the application of plant-environment relationships to ecological restoration for species selection at locations where degradation levels are high and historical communities are unclear.

  • 1 Ecology and Restoration of California Grasslands with Special
    Ecology and Restoration of California Grasslands with special emphasis on the influence of fire and grazing on native grassland species Carla D’Antonio* Susan Bainbridge* Coleman Kennedy* James Bartolomet Sally Reynolds* *Department of Integrative Biology tDepartment of Environmental Science, Policy and Management University of California Berkeley, California 94720 Funded by the David and Lucille Packard Foundation and the University of California, Berkeley 1 Introduction The grasslands of California's Mediterranean climate region are unique because they occur within a region where precipitation falls only during the cold part of the year, they have a very strong representation of annual species in their flora and they have undergone a large-scale replacement of native species by European ones over the past 150 years. Today, they occupy approximately 10 million ha either as open grassland or as understory in oak-dominated savannas and woodlands (Heady et al. 1992). Forage from these lands provides the grazing resource for range livestock production, a leading agricultural commodity in the State. In addition, California grassland and oak savanna ecosystems are extremely important as wildlife habitat (Guisti et al. 1996) and as a center of high native plant diversity. Indeed, around 90% of species listed in the Inventory of Rare and Endangered Species in California (Skinner and Pavlik 1994), occur within California grassland settings. Despite the value of California grasslands for both range production and native biological diversity, this habitat is increasingly reduced in acreage and quality due to conversion for cropland, residential and urban development and exotic species invasion. As a result, intact native grassland today is among one of the state’s most threatened ecosystems (Noss et al.

    DISSERTATION INDAZIFLAM: A NEW CELLULOSE BIOSYNTHESIS INHIBITING HERBICIDE PROVIDES LONG-TERM CONTROL OF INVASIVE WINTER ANNUAL GRASSES Submitted by Derek James Sebastian Department of Bioagricultural Sciences and Pest Management In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Spring 2017 Doctoral Committee: Advisor: Scott Nissen George Beck Paul Meiman Todd Gaines Copyright by Derek James Sebastian 2017 All Rights Reserved ABSTRACT INDAZIFLAM: A NEW CELLULOSE BIOSYNTHESIS INHIBITING HERBICIDE PROVIDES LONG-TERM CONTROL OF INVASIVE WINTER ANNUAL GRASSES Invasive winter annual grasses such as downy brome (Bromus tectorum L.) are a threat to native ecosystems throughout the US. These invasive grasses exploit moisture and nutrients throughout the fall and early spring before native plants break dormancy. This results in decreased native species abundance and development of monotypic stands. Short-term downy brome management has been shown to be effective; however, the soil seed reserve has often been overlooked although it’s the mechanism responsible for rapid re-establishment. While glyphosate, imazapic, and rimsulfuron are herbicides commonly recommended to control invasive, annual grasses, their performance is inconsistent, and they can injure desirable perennial grasses. Indaziflam is a recently registered cellulose-biosynthesis inhibiting herbicide, providing broad spectrum control of annual grass and broadleaf weeds. Indaziflam (Esplanade®, Bayer CropScience) is a cellulose biosynthesis inhibiting (CBI) herbicide that is a unique mode of action for resistance management and has broad spectrum activity at low application rates. At three sites, glyphosate and rimsulfuron provided less downy brome control than indaziflam one year after treatment (YAT). Percent downy brome control with imazapic decreased significantly 2 YAT (45-64%), and 3 YAT (10-32%).

  • Nassella Notes
    Nassella Notes By David Amme Reprinted from Grasslands A Publication of the California Native Grass Association 2003 13(4):3p Nassella Notes by David Amme Nassella is a genus that is native to the western hemisphere. Nassella includes 116 species, making it one of the largest genera in the tribe Stipeae (Barkworth and Torres 2001). Argentina has the largest number of species with over 72 species. The rest of the Nassella species are spread out over the rest of South America, Central America, Mexico, the United States and Canada. Mexico has eight native species, five of which grow in the United States (California, New Mexico and Texas). There are five Nassella species growing in California, three native and two introduced. The native purple needlegrass (N. pulchra), nodding needlegrass (N. cernua) and foothill needlegrass (N. lepida), are confined to California and northern Baja California. The introduced Nassella species include N. manicata and N. tenuissima. N. manicata is from Chile and was misidentified by Barkworth in the Jepson Manual as N. formicarum (Barkworth and Torres 2001). N. tenuissima, known as Mexican feathergrass is native to the dry open woods of Texas, New Mexico, and northern Mexico as well as Argentina. In addition to California’s three Nassella species, and the Mexican feathergrass, there are two other native Nassella species north of the Mexican border: Green needlegrass (N. viridula) of the western plains of the United States and Canada, and Texas needlegrass (N. leucotricha) of the dry open grasslands of Oklahoma, Texas and central Mexico, with a grand total of 6 native Nassella species north of the Mexican border.

Montalvo Carol W. Witham © 2004 Synonyms Stipa pulchra Hitchc. (Hickman 1993) (NRCS code STPU2); S. setigera Calif. (Munz 1974) Common name Purple needlegrass. Other names include: purple stipa, purple tussockgrass (Steinberg 2002); purple nassella; California purple needle grass; purple needle stipa (Painter 2009). Subspecific taxa None. Taxonomic relationships Species of Nassella were once considered part of the genus Stipa and are related to Stipa, Achnatherum , and Hesperostipa (Barkworth 1990). Barkworth & Torres (2001) report that there are at least 116 species of Nassella , most of which occur in South America; seven species are native to North America. Related taxa in region Nassella cernua (Stebbins & Love) Barkworth; Nassella lepida (Hitchc.) Barkworth. Amme (2003) provides hints to tell these species apart (see Distinguishing Traits, below). The non-native N. manicata (E. Desv.) Barkworth from South America strongly resembles N. pulchra and is now present in at least three counties in central CA. Taxonomic issues The Jepson Manual, 2nd Edition (JepsonOnline 2nd Ed 2010 ) will be returning to the name Stipa pulchra. The USDA PLANTS (2010) database is currently using N. pulchra (as of 9/29/10). Amme (2003) reports that N. pulchra included the species N. cernua up until Stebbins & Love (1941). Not all botanists agree with the separation of the genus Nassella from Stipa, and recent publications sometimes include the name Stipa pulchra (e.g., Roberts et al. 2004, Roberts 2008). Barkwork & Torres (2001) found diagnostic characters to separate Nassella from other species in the tribe Stipeae.
