Biodiversity

LOS ANGELES IS IN A BIODIVERSITY HOTSPOT

Biodiversity is the variety of plants, animals, and other species interacting with their environment to maintain the balance of nature. In cities, these environments include the natural areas, urban landscapes, and other built environments that these species call home.

The City of Los Angeles is fortunate to be located within a globally recognized hotspot of native biodiversity. While Los Angeles is a biodiversity jewel, this designation also means that the biodiversity here is threatened, and innovative strategies are needed to ensure its resilience and sustainability. The survival and well-being of the City’s residents also depend on ecosystem services provided by biodiversity:

  • air pollution reduction
  • adapting to a changing climate
  • mental health and educational opportunities
  • water cleansing
  • aesthetic benefits
These services are built directly from an integrated ecosystem of natural biodiversity and sustainable urban landscapes.


BIODIVERSITY MOTION

In order to protect and enhance Los Angeles's biodiversity, Councilmember Koretz, who represents the 5th Council District, introduced a Biodiversity Motion. On May 10, 2017, Los Angeles City Council unanimously adopted his Biodiversity Motion, which includes three main objectives:

  • develop an index to measure protection, enhancement, and mitigation of impacts to biodiversity
  • develop policies and projects to enhance biodiversity, including improving access for communities that lack access and contribute toward broader ecosystem functions and sustainability
  • develop options for community outreach and engagement. City Council directed LASAN to oversee efforts to evaluate biodiversity in the City and develop an index to measure no net loss going forward.

EXPERT COUNCIL

LASAN enthusiastically embarked on this journey and brought together interested individuals to form both an Expert Council and an interdepartmental Biodiversity Team. The collective knowledge and data resources from these esteemed individuals were tapped to measure the Singapore Index and to provide the recommendations presented throughout the report.


In order to measure the Singapore Index for the City of Los Angeles and develop recommendations for a customized Los Angeles Index and biodiversity practices, LASAN’s Internal Biodiversity Team received input from City staff and local experts via three main partnerships: 
 

  • An Interdepartmental Team composed of representatives from various City Departments that perform work related to biodiversity
  • A Stakeholder Group composed of individuals from City Departments, non-governmental non-profit organizations (NGOs), regulatory agencies, academics, and subject matter experts
  • An Expert Council composed of experts on various aspects of biodiversity who volunteered to lend their expertise and data to the endeavor

The Expert Council members who provided guidance on this effort represent the following organizations:  

 

  Aquatic Bioassay and Consulting Laboratories, Inc. Loyola Marymount University
  Arlene Hopkins & Associates National Park Service
  Board of Public Works Northridge Beautification Foundation
  California Department of Fish & Wildlife Santa Monica College
  California EcoDesign Santa Monica Mountains Conservancy
  California Native Plant Society Stillwater Sciences
  California State University Los Angeles StreetsLA
  Center for Biological Diversity Studio MLA
  Citizens for Los Angeles Wildlife (CLAW) The Nature Conservancy
  City Planning Theodore Payne Foundation

THE SINGAPORE INDEX ON CITIES’ BIODIVERSITY

LASAN measured the Singapore Index on Cities’ Biodiversity as the first step in implementing the Motion. Los Angeles is the first City in the U.S. to perform this measurement, joining Helsinki, Montreal, Lisbon, and a few other global cities. LASAN embraced its leadership role in this process, bringing together interested individuals to form an Expert Council and an Interdepartmental Biodiversity Team. The collective knowledge and data resources from esteemed individuals were tapped to measure the Singapore Index and provide the recommendations presented throughout this document.

Appendix B
provides additional information regarding the methods used to calculate each of the 23 indicators included in the Singapore Index for the City of Los Angeles.

2020 BIODIVERSITY REPORT

LASAN is pleased to share the 2020 Los Angeles Biodiversity Report, the second such report produced for the City of Los Angeles. This document builds upon the action items and concepts identified in the 2018 Biodiversity Report, which documented measurement of the Singapore Index on Cities’ Biodiversity for Los Angeles, and contained recommendations for a customized LA City Biodiversity Index. The report includes the following:
 

  • Chapter 1- the LA City Biodiversity Index
  • Chapter 2- the “ecotopes” spatial management framework
  • Chapter 3- an approach for measuring urban habitat quality and connectivity in Los Angeles
  • Chapter 4- biodiversity case studies
Please see links at the bottom of the page to download the report and accompanying appendices.



AN INDEX SPECIFIC TO LOS ANGELES

The LA City Biodiversity Index is tailored specifically to the Los Angeles context and is designed to monitor progress toward the no-net loss target.  The LA City Biodiversity Index was crafted with the guidance of project stakeholders and an Expert Council of local practitioners, non-governmental organizations (NGOs), scholars, and City staff.  It is intended to be institutionalized within municipal environmental management practices as a central tool in implementing a future LA Biodiversity Policy and guiding long-term management and monitoring of biodiversity stewardship. It includes three core themes of urban biodiversity: conservation of native biodiversity, social justice aspects of biodiversity, with a focus on equity, and governance and management activities.
