May 12 ·  7:30 - 9:00pm


Presenter: Steven L. Hartman

The Sepulveda Basin is the home of a Wildlife Area with an 11-acre lake, the Bull Creek Ecological Restoration Area, one of only 3 soft-bottomed portions of the Los Angeles River, Encino Creek, Woodley Creek, and Hayvenhurst Creek. Not to mention Lake Balboa.

The Sepulveda Basin was in the national news in December 2013 when the Army Corp of Engineers destroyed vast swaths of mature native vegetation under the guise of removing non-native plants. If you want to find out what happened and what are the current plans for restoring that area, attend this power point presentation by Steve Hartman, currently the chair of the Sepulveda Basin Wildlife Areas Steering Committee.

Eight-legged Science: The Spider Lab at Loyola Marymount University

Presenter: Martina Giselle Ramirez

With over 44,000 described species, spiders are perhaps the fifth largest animal order and are a major predatory group in most ecosystems. Yet, relative to their biodiversity and ecological importance, knowledge concerning the lives of most spider species is unknown. The Spider Lab at LMU started in the fall of 1999. This talk will present some of the surprising findings the students and Dr. Ramirez have made concerning several local spiders, spotlighting along the way how involvement in eight-legged science at LMU can catalyze student excellence.

Martina Giselle Ramirez received her B.S. in biology from LMU in 1981, and her Ph.D. in biology from U.C. Santa Cruz in 1990. Prior to LMU, Dr. Ramirez was a professor at Pomona College, CA (1991-1993); Bucknell University, PA (1993-1996); Denison University, OH (1996-1998); and East Stroudsburg University, PA (1998-1999). Dr. Ramirez received the Rudinica Award for Student-Faculty Research from LMU’s Seaver College of Science and Engineering (2012), as well as a Biology Mentor Award from the Council on Undergraduate Research (2013).

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.”

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
