The Effect of Connectivity on Population Viability of Mountain Lion (Puma concolor) in the East Bay, California

method
Method

How does connectivity affect the populations of Puma concolor in the Southern half of the Bay Area?

zonation
Zonation
  • Core Habitat for Mt. Lion
  • Weighted:
    • 100% Mt. Lion
    • 33% Mule Deer

Population Viability Analysis

Ramas Metapop

extinction risk
Extinction Risk

6% Probability of Extinction

No Connectivity

  • 100 Years
  • Sinks don’t help
  • # of Populations in Total
  • Assumptions
  • Circuitscape over-represents connectivity creates many sinks

31% Probability of Extinction

Moderate Connectivity

96% Probability of Extinction!

Circuitscape Predicted Connectivity

assumptions and limitations
Assumptions and Limitations
  • Relationship with mule deer
  • Visual inspection of connectivity- qualitative
  • Freeway underpass data not incorporated into circuitscape model
  • Demographic Parameters
  • Scale is too small- doesn’t include entire metapop
but what does it all mean
But what does it all mean?
  • Mountian Lion Habitat in the South and East Bay is highly fragmented by roads and urban development
  • Survival is highly dependent on inputs from 2 source populations
  • Connected to WHAT?
