A full census was completed in August, 2009. Every plant was examined and recorded as alive, dead or missing. The overall survival for the site was 96%.
Permanent plot monitoring was conducted in 2010 and 2011. This is a sampling of a portion of each field. Overall site survival in 2011 was 94.7%, indicating that their was very little mortality during the life of the project.
Monitoring determined that the habitat structure was most influenced by arroyo willow, California blackberry, coyote brush, sandbar willow and California rose. This demonstrates a complex structure, not dominated by a single species.
The average height of tree species included western sycamore (12.6 feet), black willow (11.3 feet) and Fremont cottonwood (6.6 feet).
River Partners conducted annual photopoint monitoring in order to document changes over time. Photographs were taken from identical locations from 2007 through 2012.
