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.
