Table 4. Sensitivity and elasticity estimates as derived from a population viability analysis (PVA) for Crotalus willardi obscurus (CWO) in the Animas Mountain sky island (New Mexico, U.S.A.).

			Fire Regimes
		No Fire	Low Intensity	High Intensity
Sensitivity	Fecundity	0.27	0.29	0.21
	Juvenile Survival	0.53	0.55	0.71
	Adult Survival	0.86	0.83	0.85
	TOTAL	1.66	1.67	1.77
Elasticity	Fecundity	0.23	0.26	0.24
	Juvenile Survival	0.23	0.26	0.24
	Adult Survival	0.54	0.47	0.53

Fecundity and juvenile and adult survival are estimated over 100 years under three Fire Regimes (= No Fire; Low Intensity Fire; High Intensity Fire).
