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.
