Introduction This report contains the results of a biological resources and habitat assessment conducted for the Taylor Yard Bikeway/Pedestrian Bridge Over the LA River Project (project) located in the City of Los Angeles, Los Angeles County, California. 1.1 Project Location The project would be located across the Los Angeles River in the Silverlake-Echo Park-Elysian Park Community Plan Area in the City of Los Angeles (Figure 1). Specifically, the northern abutment of the project would be located adjacent to Kerr Road and its southern abutment would be located adjacent to the Los Angeles River Greenway Trail (bikeway) approximately between Altman Street and Dorris Place.

The Project site is located at 1030–1380 North Broadway and 1251 North Spring Street, within the vicinity of the Chinatown neighborhood, downtown Los Angeles, Lincoln Heights, and Dodger Stadium/Elysian Park. The analysis was conducted in support of the Initial Study (IS) for the project to determine if additional studies or analysis are necessary. Methodology A review of existing information and a site visit was conducted to determine the biological resources that are present or have potential to occur on and adjacent to the project site. Literature Review A literature review was conducted prior to the field visit to identify special-status biological resources present or potentially present within the vicinity of the project site using the following: • California Department of Fish and Wildlife (CDFW) California Natural Diversity Database (CNDDB) (CDFW 2020a) • California Native Plant Society’s (CNPS) Online Inventory of Rare and Endangered Vascular Plants (CNPS 2020) • U.S.

However Requirements of Key in recent years, riparian habitats have been degraded, or de- stroyed by flooding, channelization, phreatophyte control, Southwestern Woody agricultural practices, overgrazing, recreation, and off -road vehicle abuse.

Flooding has Riparian Species been responsible for the destruction of many mature ripar- ian forest stands in the Southwest, but flooding is also necessary for the establishment of many stands (Brady et al., 1985).

  • Nr 222 Native Tree, Shrub, & Herbaceous Plant
    NR 222 NATIVE TREE, SHRUB, & HERBACEOUS PLANT IDENTIFICATION BY RONALD L. ALVES FALL 2014 NR 222 by Ronald L. Alves Note to Students NOTE TO STUDENTS: THIS DOCUMENT IS INCOMPLETE WITH OMISSIONS, ERRORS, AND OTHER ITEMS OF INCOMPETANCY. AS YOU MAKE USE OF IT NOTE THESE TRANSGRESSIONS SO THAT THEY MAY BE CORRECTED AND YOU WILL RECEIVE A CLEAN COPY BY THE END OF TIME OR THE SEMESTER, WHICHEVER COMES FIRST!! THANKING YOU FOR ANY ASSISTANCE THAT YOU MAY GIVE, RON ALVES. Introduction This manual was initially created by Harold Whaley an MJC Agriculture and Natural Resources instruction from 1964 – 1992. The manual was designed as a resource for a native tree and shrub identification course, Natural Resources 222 that was one of the required courses for all forestry and natural resource majors at the college. The course and the supporting manual were aimed almost exclusively for forestry and related majors. In addition to NR 222 being taught by professor Whaley, it has also been taught by Homer Bowen (MJC 19xx -), Marlies Boyd (MJC 199X – present), Richard Nimphius (MJC 1980 – 2006) and currently Ron Alves (MJC 1974 – 2004). Each instructor put their own particular emphasis and style on the course but it was always oriented toward forestry students until 2006. The lack of forestry majors as a result of the Agriculture Department not having a full time forestry instructor to recruit students and articulate with industry has resulted in a transformation of the NR 222 course. The clientele not only includes forestry major, but also landscape designers, environmental horticulture majors, nursery people, environmental science majors, and people interested in transforming their home and business landscapes to a more natural venue.

  • Tamarix Ramosissima Global Invasive
    FULL ACCOUNT FOR: Tamarix ramosissima Tamarix ramosissima System: Terrestrial Kingdom Phylum Class Order Family Plantae Magnoliophyta Magnoliopsida Violales Tamaricaceae Common name salt cedar (English), Sommertamariske (German), tamarisk (English), tamarix (English) Synonym Tamarix pallasii , var. brachystachys Bunge Tamarix pentandra Similar species Tamarix aphylla, Tamarix canariensis, Tamarix chinensis, Tamarix gallica, Tamarix parviflora Summary Tamarix ramosissima is a rampantly invasive shrub that has dominated riparian zones of arid climates. A massive invasion of T. ramosissmia in the western United States has dominated over a million acres. Typically found in conjunction with other Tamarix species and resultant hybrids, T. ramosissima displaces native plants, drastically alters habitat and food webs for animals, depletes water sources, increases erosion, flood damage, soil salinity, and fire potential. view this species on IUCN Red List Global Invasive Species Database (GISD) 2021. Species profile Tamarix ramosissima. Pag. 1 Available from: http://www.iucngisd.org/gisd/species.php?sc=72 [Accessed 08 October 2021] FULL ACCOUNT FOR: Tamarix ramosissima Species Description Tamarix ramosissima is a semi-deciduous, loosely branched shrub or small to medium-sized tree. The branchlets are slender with minute, appressed scaly leaves. The leaves are rhombic to ovate, sharply pointed to gradually tapering, and 0.5 - 3.0mm long. The margins of the leaves are thin, dry and membranaceous. Flowers are whitish or pinkish and borne on slender racemes 2-5cm long on the current year's branches and are grouped together in terminal panicles. The pedicels are short. The flowers are most abundant between April and August, but may be found any time of the year. Petals are usually retained on the fruit.
