Vegetation - Ballona Wetlands [ds2966]

The primary purpose of CDFW’s goal of developing fine-scale digital vegetation maps is part of the California Biodiversity Initiative Roadmap of 2018. The mapping study area consists of approximately 600 acres within Ballona Wetlands Ecological Reserve of Los Angeles County, California. Reconnaissance was conducted by CDFW ecologists on May 9-11, 2006 to collect a preliminary list of vegetation types to accurately represent the study area.

On June 13, 2006, I.K. Curtis Aerial Photography took a true color orthophoto at 1-foot pixel resolution (±1:16,800) under contract to the Coastal Conservancy and Brad Henderson (CDFW) combined the preliminary vegetation list to manually draw polygons overlaid the air photo. GreenInfo used the drawing and air photo for a digitized map draft of polygons to be verified and assessed by field crews for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes on June 19-22, 2007.

Field crews noted 8 exotic, invasive species in the map polygons worthy of special interest in regards to restoration planning decisions. Field reconnaissance enhanced map quality. There was a total of 61 mapping classes.

No accuracy assessment of this map has been performed because ecologists visited every polygon in the field.
