  • Challenges to Introducing and Managing Disturbance Regimes for Holocarpha Macradenia, an Endangered Annual Grassland Forb
    Challenges to Introducing and Managing Disturbance Regimes for Holocarpha macradenia, an Endangered Annual Grassland Forb KAREN D. HOLL∗ AND GREY F. HAYES† Environmental Studies Department, University of California, Santa Cruz, CA 95064, U.S.A. Abstract: Introducing rare plants to new sites for conservation to offset effects of habitat destruction requires detailed knowledge of habitat requirements, plant demography, and management needs. We conducted a factorial experiment replicated at three coastal prairie sites to test the effects of clipping frequency and litter accumulation on seed germination, seedling survival, reproduction, and seedling recruitment of introduced populations of the endangered, tall-stature, annual forb, Holocarpha macradenia (DC.) E. Greene. Clipping favored H. macradenia, primarily by enhancing seed germination and flower production. Litter accumulation had no effect on seed germination, even after 5 years of treatments. Seedling recruitment was highly site specific with large numbers of recruits recorded at only one of three sites. Although recruitment of seedlings was higher in clipped plots for 2–3 years, by 4–5 years after introduction very few seedlings survived to reproduction in any treatment. We attribute this result to a combination of poor habitat quality, small population size, and lack of a seed bank. We were unsuccessful in introducing this relatively well-studied species of concern to apparently suitable habitat at multiple sites in multiple years, which suggests that translocating rare plant populations

  • Telegraph Avenue Rapid Corridors Project Natural
    Telegraph Avenue Rapid Corridors Project March 2020 ATTACHMENT A – CEQA CHECKLIST Project Description The Alameda-Contra Costa Transit District (AC Transit) plans to implement the Telegraph Avenue Rapid Corridors Project (Project) to: • Improve transit operations along 4 miles of Telegraph Avenue from 20th Street in Oakland to downtown Berkeley; • Improve 3 miles of Grand/West Grand Avenue from Maritime Street to Lake Park Avenue in Oakland; • Deliver a portion of the Southside Pilot Transit Project in the City of Berkeley; • Provide bus stop improvements and relocations north of 52nd Street. No bus stop improvements south of 52nd Street are proposed as part of this Project, as they will be implemented by the City of Oakland Department of Transportation. • Improve transit reliability for Line 6 along Telegraph Avenue; and Lines 12 and NL along Grand/West Grand Avenue to implement Rapid Bus service as a short-term strategy recommendation in the AC Transit’s Major Corridor Study (2016). Figures 3 through 6 show diagrammatic maps of the planned improvements. Tables in Attachment 1 describe the bus stop locations where improvements will be made along with a description of the planned enhancements. Upgrading the Project corridor infrastructure would produce cascading benefits that include ridership growth, reducing auto trips, and improving air quality. These benefits and goals are consistent with AC Transit’s strategy to maximize operational benefit and efficiency, and achieve Metropolitan Transportation Commission’s Transit Sustainability Project performance metrics. Key project Elements include the following: Improvements to Bus Stops: Providing longer bus stops will allow buses to pull parallel to the curb and improve bus door access.

    Holocarpha macradenia (Santa Cruz tarplant) Plant community composition, seedling density, pollination, seed dispersal and plant vigor/phenology Prepared for: California Department of Fish and Game Habitat Conservation Branch 1416 Ninth Street, 12th Floor Sacramento, CA 95816 By: Grey Hayes, PhD Department of Environmental Studies University of California, Santa Cruz Santa Cruz, CA 95064 May 2003 Introduction The following report summarizes work funded by CDFG to study various aspects of the ecology of Holocarpha macradenia (Santa Cruz tarplant). In 1999 – 2001, I collected data on the plant community composition, seedling density, pollination, seed dispersal and plant vigor/phenology in and around the natural populations at both the Porter Ranch and Arana Gulch. Community Composition Introduction In the following experiment, I measured the plant community composition in the natural population of Holocarpha macradenia as well as grazed and ungrazed areas of coastal prairie near this population and in coastal prairie plots that were experimentally manipulated with grazing-associated disturbances. Comparisons between these sites may further the understanding of the species with which Holocarpha macradenia associates and methodologies that might be used to manipulate those associates to better resemble that where the species proliferates. Methods -PORTER RANCH POPULATION- In 2000 and 2001, I randomly placed 8 and 16, 0.5 _ 0.5-m grids within the population of tarplant east of the drainage at the Porter Ranch. I recorded each species once at each sample point if it intersected a 1.8-mm metal pin lowered at intersections of strings that were spread across a 0.5 _ 0.5-m grid at 10 cm intervals (a total of 25 points).

  • Holocarpha Macradenia (Santa Cruz Tarplant) 5-Year Review: Summary and Evaluation
    Holocarpha macradenia (Santa Cruz tarplant) 5-Year Review: Summary and Evaluation Photos: Kim Hayes, Elkhorn Slough Foundation U.S. Fish and Wildlife Service Ventura Fish and Wildlife Office Ventura, California February 2014 5-YEAR REVIEW Holocarpha macradenia (Santa Cruz tarplant) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed. If we recommend a change in listing status based on the results of the 5-year review, we must propose to do so through a separate rule-making process defined in the Act that includes public review and comment.
