About LASAN's Biodiversity Program

LASAN’s Biodiversity Program oversees the City’s efforts to protect and enhance biodiversity.

We are currently on the cusp of a mass extinction, with over one million species at future risk. Without action, we could soon see biodiversity collapse, and we cannot survive without biodiversity. Reversing biodiversity loss is crucial for food security, climate stability, and public health.


LASAN’s Biodiversity Program oversees the City’s efforts to protect and enhance biodiversity. LASAN’s Biodiversity Program originated in 2017 when the LA City Council adopted the Biodiversity Motion and directed LASAN to lead Citywide Biodiversity efforts.


“Los Angeles is a City where all Angelenos value biodiversity, honor and respect nature, and steward the natural world, ensuring that ecosystems are protected, enhanced, and restored, environmental and public health benefits are maximized and equitably shared by all, and that Los Angeles is a resilient, biophilic City for generations to come.”

In order to track progress on biodiversity initiatives, the Biodiversity Team is using a special tool called the LA City Biodiversity Index. The LA City Biodiversity Index is tailored specifically to the LA context and is designed to monitor progress toward the no-net loss of native biodiversity 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. The hope is for the index to be institutionalized as a tool to guide long-term management and monitoring of biodiversity. The index includes 25 individual metrics that cover three major themes:

  1. Conservation of Native Species & Ecosystems
  2. Social Equity Considerations
  3. Management & Governance

In addition to performing regular assessments of the LA City Biodiversity Index, the Biodiversity Team is working to develop biodiversity guidelines, brainstorming implementation projects to benefit biodiversity, and performing community outreach to encourage biodiversity stewardship.
