Santa Monica Mountains Case Study

• Species richness masks unevenness among the species

• Shannon Equitability Indices (H'/H'max,1 = even; 0= uneven):
• La Jolla Valley HE = 0.83
• Serrano Valley HE = 0.78
• Charmlee Park HE = 0.64
• Simpson's Index of Diversity (1 - D, 1= even; 0 = uneven)
• La Jolla Valley 1-D = 0.89
• Serrano Valley 1-D = 0.80
• Charmlee Park 1-D = 0.66
• 9 native species were dominant (enough to permit statistical analysis):
• all 9 found in La Jolla Valley
• 5 found in Serrano Valley
• 6 found in Charmlee Park
