Councilmember Koretz has spearheaded several efforts to preserve local biodiversity as part of his #BioDiversifyLA project. Los Angeles is located within the California Floristic Province, one of only 33 biodiversity hotspots in the world. Biodiversity hotspots are areas that contain many species which cannot be found anywhere else on the planet, so it is vitally important to protect the habitats in which they live.


“As a changing climate becomes more and more apparent--through the drought, wildfires and increasing extreme storm events,” Councilmember Koretz says, “it is vital to catalog the plants and animals with whom we share Los Angeles, so we know what else we have to lose if we do not take action more quickly.”

The full text of each individual motion can be found by clicking on the links below.

Below is the press conference announcing the introduction of Councilmember Koretz’s biodiversity motion, which asks the City to catalog and protect its biodiversity. He is joined here by Hollywood’s famous mountain lion, P-22, and representatives from CLAW (Citizens for Los Angeles Wildlife), the Natural History Museum, the National Park Service, Urban Wildlands, the Los Angeles Sanitation Department, the Nature Conservancy, and the Council for Watershed Health.


Councilmember Koretz has been invited by prominent local organizations to speak at a number of local biodiversity-related events, including moderating a panel on biodiversity at the Bay Foundation’s annual State of the Bay Conference.

This panel included CD-5 resident and past President of the Bel Air/Beverly Crest Neighborhood Council, Travis Longcore (below, far right).


Councilmember Paul Koretz gives a keynote speech below at the Council for Watershed Health’s symposium entitled, “Enhancing Urban Biodiversity: A Multi-Sector Approach for a Sustainable Los Angeles.”

The symposium explored the opportunities for protecting biodiversity that are presented by the region’s rapid growth in transportation, climate adaptation, green infrastructure and open space projects.


Wildlife Corridors motion

Councilmember Koretz is pleased to announce that his motion to protect wildlife corridors through the hillside communities of Los Angeles was approved unanimously by the City Council on Earth Day 2016. The first stage will cover the area from the 405 freeway to Griffith Park. The animals in Griffith Park and the hills, including our famous Hollywood mountain lion, P-22, are trapped by freeways and development and are unable to escape to breed, which is resulting in inbreeding among deer, for one example. Creating a wildlife corridor does not negatively impact homeowners, instead, it ensures that, as homes are built, there is an allowance for an open corridor which allows wildlife to come and go. Animals which are not trapped are healthier, calmer and much easier to share our urban community with.

Rodenticides motion

The Councilmember was dismayed to read a newspaper story that in California 92% of dead bobcats analyzed tested positive for rodenticides. Healthy bobcats have been dying of severe mange, a common skin disease caused by parasitic mites normally afflicting canines. After a little research, he found that rodenticide, also known as rat poison, is having a massive negative impact on raptors like hawks, owls, eagles and falcons, and on four-legged creatures like foxes, martens, minks, coyotes and mountain lions. In fact, our famous Hollywood mountain lion, P-22, was found to be poisoned by first generation rodenticide. He has, fortunately, survived, but the problem goes on.

With the partnership of CLAW (Citizens for Los Angeles Wildlife), Councilmember Koretz introduced a motion calling on our City departments to find more sustainable ways of controlling the rodent and squirrel populations in our parks, including Griffith Park, in order to improve the health of our local ecosystems. As of 2014, the Rec and Parks Department stated that they have stopped using second generation rodenticides. Councilmember Koretz believes the City can go further to protect its wildlife and its domestic animal populations (cats and dogs have also been known to become ill by exposure to rodenticides).

Let's Buy a Mountain

Councilmember Koretz is working hard with Councilmember Ryu and residents in Districts 4 and 5 to preserve open space and protect the biodiversity of our surrounding landscape. In late summer of 2015, residents of Laurel Canyon learned that a plot of land on a nearby mountain was to be opened up for development, and joined together to begin a campaign to purchase and preserve these 17 acres of nearly pristine hillside in historic Laurel Canyon. Ongoing development is tearing apart habitat and disrupting sensitive biodiversity. This is a once in a lifetime opportunity to permanently preserve 17 acres of open space.


We need to raise $1.6 million by April 2017. Donations (all tax-deductible) can be made on the CLAW website or checks may be made payable and sent to:

Sepulveda Basin Wildlife Reserve Protection motion

Councilmember Koretz shares one of the hidden gems of Los Angeles with Councilmembers Martinez and Blumenfield, whose districts also border it. The Sepulveda Basin Wildlife Reserve is one of the few areas on the Los Angeles River specifically set aside for wildlife. With its willows and sycamores, migratory birds like Canadian geese, herons and egrets, and smaller birds like woodpeckers, orioles and goldfinches, and a myriad of other critters and fish, it is a haven of peace and rest for wildlife and Angelenos alike, a welcome oasis in the midst of our concrete jungle.

We have a crack team of environmental experts and concerned neighbors looking after it. In addition to our own Department of Rec and Parks, the Sepulveda Basin Wildlife Areas Steering Committee includes folks from the Encino and Lake Balboa Neighborhood Councils, the California Native Plant Society, the Audubon Society, the Canada Goose Project, the Angeles Chapter of the Sierra Club, TreePeople, the Southwestern Herpetologist Society, and the River Project.

They were on the scene when the Army Corps of Engineers senselessly destroyed the South Wildlife Reserve a couple years ago and took the Councilmember out for a first-hand look at the destruction. They worked hard to institute better communication from the Army Corps going forward. They weigh in on any and all Army Corps proposals, including kayaking on the river. Most recently, they worked with our Los Angeles Police Department and brought the Councilmember a list of improvements in police enforcement which could be made to protect animals and birds from being hunted, bird eggs from being collected and plants from being stolen. All of which were sadly occurring. But not for long.

In December, 2015, the City Council approved an ordinance which provided the missing protections. We expect these changes to better protect the plants and wildlife going forward. Councilmember Koretz sends his appreciation to the Sepulveda Basin Wildlife Areas Steering Committee and looks forward to a continued strong relationship with them.

BioScan and BioBlitz Projects with the Natural History Museum


The District 5 office has also partnered with the LA Natural History Museum for two collaborative efforts. The first was the month-long BioSCAN effort, intended to identify the insects which live around City Hall as part of a larger effort to capture and examine previously unknown insect species in the Los Angeles area. In just one summer month, we identified several hundred species from over 90 families. Some are common backyard residents (Argentine ants, green lacewings, European honey bees), but the majority were surprising dwellers in our urban core.

Ants, bees, and wasps (all in the insect order Hymenoptera) are the largest group found in these traps in terms of diversity, but also the smallest in terms of size. Thousands of microscopic wasps only a few millimeters in size were collected, as well as 6 different species of bee. Low ant diversity was expected: the traps we used mainly to collect flying, not crawling, insects. Photos of some of the insects we collected can be seen below.

The second, related, effort was the BioBlitzLA project, in which LA residents spent a day as Citizen Scientists, photographing plants and animals around Grand Park and City Hall in order to help scientists understand the urban ecosystem within Los Angeles. A BioBlitz is a focused, several-hour endeavor intended to explore and document the wildlife and plant life on the grounds of Los Angeles City Hall and Grand Park. Dozens of volunteer “citizen scientists” were trained and set loose with their phones to photograph and share what they found on social media, so that the scientists at the Natural History Museum could better understand the nature we have here in LA. With a dedicated crew of 9 citizen scientists, we managed to document 28 species in 1 ½ hours, including orb weaver spiders, argentine ants, flower flies and fox squirrels.
