This technical note discusses methods for using these data in combination with locally meaningful jurisdictional boundaries to calculate local measurements of indicators on several themes—including access to urban amenities, air quality, biodiversity, flooding, climate change mitigation, heat, and land protection and restoration—relevant to urban decision-makers, researchers, and other stakeholders.
Biodiversity in Los Angeles is truly unique. On one hand, LA includes the highest population density of all major U.S. cities according to the 2010 U.S. Census, and is known to be one of the most “park poor” cities in the country1, 2. On the other hand, LA falls within a “Global Biodiversity Hotspot” and the City includes an exemplary range of biodiversity and large natural areas. This study documents approximately 1,200 different native species recorded within the City, and perhaps more than double that are present, but unrecorded.
This 2021 Report Card on Ecosystem Health provides an in-depth look at the region’s efforts in moving toward a more resilient environment and community for people and native wildlife. A healthy and improved ecosystem requires protecting and restoring high-quality habitats and native biodiversity; reducing ecosystem threats like wildfire and invasive species; and ensuring every Angeleno has access to nature and its benefits such as clean water, shade, and respite through policy solutions that address the region’s inequities.
