Wieder Regional Park OCP OC Parks Restoration Ecologist Conservancy Restoration Ecologist Restoration Project proposed restoration project USEPA United States Environmental Protection Agency USFWS United States Fish and Wildlife Service iii 1.0 INTRODUCTION The purpose of the Habitat Restoration Plan (HRP) is to restore native and wildlife habitat by removing invasive nonnative plants and planting native plants to increase plant species diversity and native plant coverage within approximately 9.52ac portion of the Harriett Wieder Regional Park (HWRP) in the City of Huntington Beach, County of Orange, California (Restoration Project). The Restoration Project site is located at the southern end of the Bolsa Chica Wetlands on the north side of Seapoint Avenue between Palm Avenue and Doral Drive, and adjacent to the Bolsa Chica Ecological Reserve (BCER) (Figure 4) (Project Site). This Restoration Project is the first step in the restoration of native habitat at the southern edge of the BCER, which is a relatively narrow undeveloped bluff top area known as the Huntington Beach Mesa (Huntington Mesa). The Restoration Project is being undertaken by the Bolsa Chica Conservancy (Conservancy) using funds provided by the Orange County Transportation Authority (OCTA) with support from local ecologists and restoration specialists. OCTA is providing Measure M funds ($475,000 approved by the OCTA Board of Directors in 2012) specifically earmarked for mitigating impacts to native habitat resulting from regional transportation improvements. Said funds will be used for the development, installation, maintenance, and monitoring (including long-term) of the Restoration Project. The HRP described on the following pages accomplishes two important public policy objectives; 1) mitigate environmental impacts associated with regional transportation improvements and; 2) implement habitat restoration consistent with the HWRP 1997 Updated General Development Plan previously approved by both the County of Orange and the City of Huntington Beach. The Conservancy was established in 1990 by a coalition of government, community, business, and environmental leaders. It is a private, nonprofit organization, that provides educational and habitat restoration programs designed to promote public awareness of the important role wetlands play in the coastal marine environment. Since its inception, more than 450,000 visitors of all ages have participated in the Conservancy’s educational and restoration programs throughout the BCER. These programs feature outdoor education and hands-on field activities that allow participants to connect theory with real-life science, including hands-on restoration programs involving native plant propagation and installation as well as nonnative plant management. In addition to educational programs designed for schoolchildren and the visiting public, the Conservancy regularly hosts public outreach events intended to provide the general public with opportunities to participate in cleanup efforts, habitat restoration, and scientific research projects. In 1992, the County of Orange (County) approved a General Development Plan (GDP) for the 106- ac HWRP. In 1997, the GDP was updated. The GDP calls for HWRP to be primarily passive in nature comprised of native habitat restoration areas, pedestrian trails, scenic overlooks and an interpretive center to provide environmental education opportunities for the public. The County currently owns approximately 34 ac of parkland designated as HWRP. HWRP lies within the jurisdiction of both the County of Orange (7 ac) and the City of Huntington Beach (27 ac). 1 In 1997, the County and the City of Huntington Beach (City) each approved

Little work, however, has been conducted previously in the southwestern portion of the range which includes the San Mateo Canyon Wilderness Area of the Cleveland National Forest. This study reports the results of our floristic surveys conducted in the wilderness over a three-year period, from December 1991 through October 1994. The study area, encompassing the headwaters of the San Mateo Canyon watershed, is topo­ graphically and geologically diverse.

Survey trips associated with the first objective have been completed to southern Spain and western Portugal and southern France to finish pod collections as well as faunal surveys. The planned trip to Morocco has had to be delayed due to unavailability of collecting permits. Analysis of the results of all trips to-date is presented. Eighty five species of phytophagous arthropod have now been found on French broom. Two potential agents, the stem-mining beetle (Agrilus antiquus) and fly (Chyliza leptogaster) appear to be capable of killing the plant prior to maturity, while the highly specific apionid weevil (Lepidapion ?argentatum) can destroy up to 63% of the seed production in the native range. The specialist psyllid, Arytinnis hakani, also appears to be highly damaging. The natural enemy fauna was most diverse and the levels of predispersal seed losses to specialist seed feeders were highest in the Western Mediterranean in particular southern Spain, but there is high variation between sites, probably due to habitat, weed infestation size and age.

Thorne Introduction The choice of the Santa Ana Mountains for a floristic study resulted from the authors' curiosity about a region that is relatively untouched, biolog­ ically speaking, and that is rather isolated from other ranges of southern California. The presence of the Cleveland National Forest, Trabuco Dis­ trict, within a large portion of this range and the resultant protection to watershed and biota which it provides, have allowed the vegetation and wildlife of this region to retain much of their original wildness despite their proximity to a large population center. Current concern for preservation of the environment requires detailed surveys of areas like the Santa Ana :\fountains. It is hoped, therefore, that this flora will be of some help to the scientists and their students who have recently shown considerable interest in this range. Although the main access to these mountains is over unpaved and rough Forest Service truck trails, many of which are behind locked gates during fire-season closure, the citizenry has crowded into this area for recreational purposes at an alarming rate.
