Maintenance Manuals For
Residential Native Plant Gardens

Presenter: Ellen Mackey

After the dust clears from removing your lawn and replacing it with native plants, you need a long-term-care plan to keep your garden healthy and happy for years into the future.  Ms Mackey will review the process and resources needed to create tailor-made manuals for residential native plant gardens. Before losing track of their garden plans, irrigation info, species info, and other resources, native plant gardeners would be prudent to pull together all of this data  into one package. Maintenance manuals document the garden concept, planting plan, irrigation plan, storm water plan (if present), common weeds, and hardscape care and can be targeted to various audiences.  Unique to these plans is the Maintenance Checklist, a site-specific month by month schedule of tasks. Her presentation will be richly illustrated with examples from Council for Watershed Health projects such as Old Marengo Park and Elmer Ave.  Manuals from these projects are available on the Council web site for download and can be used as a template and easily adapted by individual gardeners.

Ellen Mackey is a Senior Ecologist who edited the Los Angeles River Landscaping Guidelines and Plant Palettes (2004); coauthored the Care and Maintenance of Southern California Native Plant Gardens (2006); co/authored the Old Marengo Park Maintenance Manual and Elmer Avenue Maintenance Manuals; leads the Native Seed Resources Coalition, creating a reliable supply of locally native plants for local landscaping projects.

Her front-yard native plant landscaping is certified by the National Wildlife Federation’s Wildlife Habitat Program. For fourteen years her home and garden have been open to the public in October as a sustainable home in the American Solar Energy Society, National Tour of Solar Homes and for five years as part of the Theodore Payne Foundation’s annual garden tour in April. She is an avid organic, urban farmer who lives in the urban/wildland interface and uses companion planting, composting, and other methods to create a beautiful, productive backyard garden and orchard.

Native Wildflowers of the
Palos Verdes Peninsula:
A hiker’s guide to the flowering native plants in  preserves and open spaces

Presenters: Ann Dalkey and Yvetta Williams

The presentation will begin with a short description of the Palos Verdes Peninsula Land Conservancy. Then the authors will talk about how they met and began their partnership in creating the guidebook of Native 
Wildflowers of the Palos Verdes Peninsula. Their goal was to create a user-friendly guidebook so that people with no botanical knowledge can easily identify a plant while hiking on the Palos Verdes Peninsula. Their presentation will show how the guidebook is organized and how one can use it, featuring pretty photos of flowers throughout. Afterwards, the authors will be happy to autograph books for people who want to purchase a copy ($20, proceeds go to the Palos Verdes Peninsula Land Conservancy). 

Though they are bound by shared passions for wildflowers, the coastal sage scrub habitat, and the natural inclination to photograph everything, Ann and Yvetta each brought different strengths to the effort. As a career marine biologist, Ann is well familiar with scientific names and the technical requirements for defining species characteristics. Yvetta, a life-long learner who grew up and still lives on the Palos Verdes 
Peninsula, possesses a naturalist’s knowledge of the plant species, when they bloom, and where they are located, along with the Native Americans’ uses of the plants.

New Pests Threaten Our
Native Trees

Miss Sabrina Drill, Ph.D. UCCE posted the new OAK THREAT VIDEO online. To see it please go to

Oaks are emblematic to the California landscape. An important source of food for past Californians, we still come to these trees today for shelter, shade, and beauty, in addition to the values they provide as wildlife habitat. Oak woodlands cover more than 7 million acres, and oaks provide refuges in parks, backyards, and along streets in urban and suburban areas. But oaks in Southern California are faced with several serious threats, including changing land uses, fire, and insects and diseases.

 New and old pest species are affecting these iconic trees. New threats include the Golden Spotted Oak Borer and the Polyphagous Shot Hole Borer, and woodlands in the northern part of the state have been devastated by
Sudden Oak Death.


Save LA River Open Space is committed to preserving this last open space next to the Los Angeles River in the San Fernando Valley by creating the L.A.River Natural Park at 4141 Whitsett Avenue in Studio City. The goals for this unique property on the L.A. River:

•Create and preserve public open space

•Create a unique L.A. Riverfront site

•Treat polluted water runoff from surrounding areas sending clean water into the L.A.River

•Protect historical recreational uses including golf and tennis

•Create pedestrian and bicycle trails — linking to regional bicycle paths and local businesses

•Provide Los Angeles River and River Trail access

Save LA River Open Space is working to protect this important open space in perpetuity for the community to enjoy. Public and private financing is being explored.

We are pleased to bring this vision to the community and look forward to working with the owners, civic leadership, and community stakeholders to make this a reality.

Prescribed Fires Do Not Reduce Future Area Burned in Central and Southern California

New research findings from Jon Keeley and others on utility of managed fire in southern California. 
Interesting management implications:
  • Based on past data, prescribed fires in coastal southern California have no effect on reducing area burned by future fires.
  • Prescribed fire may have more impact with management strategies designed to reduce ignitions, or to encourage planning decisions that minimize the spread of fires into urban environments.
  • Regional planners seeking to reduce fire hazard risk may need to investigate other management strategies, such as ignition prevention and invasive plant management.

Lawsuit Challenges Second Massive Newhall Ranch “Village”
    Sprawling Development in Floodplain would Devastate Wildlife Habitat, Hurt Cultural Resources
     Five public-interest groups sued Los Angeles County in superior court on Wednesday over its approval of permits for the
second phase of the sprawling Newhall Ranch development — Mission Village. The Newhall Ranch development, conceived in the 1980s as one of the largest single residential development projects ever contemplated in California, is archaic and out of step with contemporary urban planning. 
    The project is intended to eventually include 60,000 housing units — the size of a mid-size city — including development in the floodplain along the
Santa Clara River, the last mostly free-flowing river left in Los Angeles County. The sprawling project threatens endangered species and natural areas and will bury many of the river’s tributaries.
    The lawsuit — brought by the California Native Plant Society, Center for Biological Diversity, Friends of the Santa Clara River, Santa Clarita Organization for Planning the Environment (SCOPE) and Wishtoyo Foundation and its Ventura Coastkeeper program — challenges the legality of the county’s approval process in order to protect the rare plant, animal, cultural resources and water quality.
     The plan approved by the county on May 15 will develop open space that is home to endangered species in and along the Santa Clara river; eliminate habitat for the highly endangered San Fernando Valley spineflower; harm California condor habitat; and unearth and desecrate American Indian burial sites, sacred places and cultural natural resources.
     “Decades have passed, planning principles have shifted and improved, and yet the county has failed to incorporate contemporary planning principles into this dinosaur of a project,” said David Magney with the California Native Plant Society. “As a result, rare plants, including the San Fernando Valley spineflower, are going to be needlessly bulldozed and replaced by more strip malls, parking lots and houses no one can afford.”
     “It’s unimaginable that L.A. County is so reckless with the last free-flowing river in the region,” said Ron Bottorff with the Friends of the Santa Clara River. “Southern California has paved over and lost all but 3 percent of its historic river woodlands, yet these are resources are key to protecting our precious water.”
     The Santa Clara River Valley is home to a great diversity of very rare species, among them the unarmored threespine stickleback fish, California condor, least Bell’s vireo, southwestern willow flycatcher, California red-legged frog, arroyo toad, southern steelhead trout and San Fernando Valley spineflower. Wildlands of the Santa Clara River provides a full accounting of rare environmental resources of this precious landscape.
     “Developing in endangered species habitat pushes rare plants and animals to the brink of extinction,” said Ileene Anderson, a biologist with the Center for Biological Diversity. “These days, smart planning protects them instead of destroying their habitat.”
     Los Angeles County approved an overall plan for the Newhall Ranch development more than a decade ago. Approval of this second phase, called Mission Village, follows just months after the county approved the first phase, Landmark Village. Northern Los Angeles County is already plagued by high foreclosure rates and thousands of permitted housing units that have not been built. Financial bankruptcy by the development’s previous investors cost California’s public pension fund more than $970 million of state employees’ retirement. New investors are out-of-state hedge fund managers with no interest in California’s rich natural legacy.
     “Before a single house has been built, Newhall Ranch has already cost California’s taxpayers and workforce, including the county’s own staff, nearly a billion dollars of lost pension funds,” said Lynne Plambeck, president of the Santa Clarita Organization for Planning the Environment. “Although the state will never recover any of the largest single loss ever suffered by CalPERS, and will spend millions more in public monies to build roads, bridges and other infrastructure to serve this project, the county has once again endorsed this same development that will threaten the region’s water supply, worsen air pollution and cause further gridlock on our highways.”
     “The project will impart irreversible impacts to the ecological integrity and water quality of the Santa Clara River watershed and Ventura’s coastal waters, harming the wellbeing of watershed residents and visitors for years to come,” said Jason Weiner, associate director and staff attorney for the Wishtoyo Foundation’s Ventura Coastkeeper Program.
     “The impacts to hundreds upon hundreds of our burial sites, and natural cultural resources such as the California condor that are such a vital component of our culture and religious practices, will be devastating and irreversible,” said Mati Waiya, a Chumash ceremonial elder and executive director of the Wishtoyo Foundation.

     “Mission Village contains a former oil field now proposed for housing. Project information on toxic contamination was substantially changed at the very last minute just prior to the county’s approval,” said attorney Dean Wallraff. “Tetrachloroethene (PCE) contamination was discovered on the old oil field but the public was not given a chance to review any of this data in the review process, which is a violation of law.”

Los Angeles County
General Plan Update 2035 –
Revised EIR Schedule

The development of the Draft Environmental Impact Report (EIR) is currently underway. It is estimated releasing the Draft EIR to the public in Spring 2013. Please continue to check the web site at for updates. We will provide public notice and send out announcements when the Draft EIR is available for public review.

The scope of the Draft EIR includes the General Plan Update, Antelope Valley Area Plan Update
(Town & Country), zone changes, revisions to existing zones, the creation of new zones, and comprehensive updates to Zoning Code provisions related to Significant Ecological Areas and Hillside Management Areas.

What is the General Plan Update?

The General Plan Update is the first comprehensive update to the Los Angeles County General Plan in over 30 years. Upon adoption, the General Plan will guide growth and development in the unincorporated areas of Los Angeles County through the year 2035. It provides a framework of goals, policies and implementation programs centered on the theme of sustainability. For more information, please visit

What is an EIR?
The California Environmental Quality Act (CEQA) is a statute that requires state and local agencies to address the environmental impacts of a project, such as the General Plan Update. Pursuant to CEQA, the General Plan Update EIR will identify potential environmental impacts and feasible mitigation measures. The preparation of an EIR includes specific time frames for public notice and hearings.

An ecofriendly future for light rail stations

Our goal is simple: get the MTA and Expo Authority to use native species for the station landscaping in phase two of the Expo light rail line.

The site is still being fine-tuned, but the basic concepts are all there.  This grassroots movement needs help from each of you in spreading the word on this long-overdue change in the way we use plants in our public projects.  Under the Resources & Links section of the website, you will find copies of both our colorful Brochure (for interested stakeholders) and our White Paper (for media and government).  Please feel free to distribute both documents to anyone who will read them!

The website also includes a link to our petition on this matter.  Please sign the petition, if you will.  You can link directly to the petition via:

An important advance in systematics of California plants:

The Jepson eFlora is now on line.


The Jepson eFlora initially parallels the second edition of The Jepson Manual, Vascular Plants of California, which is the work of 300 authors and editors being published by the University of California Press. 

The eFlora includes all of the taxonomic treatments of the print Manual and has in addition treatments for taxa that were excluded from the print Manual because of doubts about naturalization status. Interactive distribution maps linked to specimen data from the Consortium of California Herbaria are included.  Words that were abbreviated to save space in the print Manual have been expanded.  Keys are linked to the treatments to which they refer. Accepted names and synonyms can be searched for.  The eFlora is linked to the Jepson Online Interchange, and from there to numerous electronic tools.

The Jepson Herbarium will work with the treatment authors and users to keep the eFlora in sync with advances in California botanical knowledge.


Ecovisions has produced a series of YouTube videos about invasive plants, specifically English ivy, brooms, yellow starthistle, pampas grass and more. Find them at
