Summary
We used 29 years of data on boreal chorus frogs at two sites to view life-history, estimate demographic parameters, assess weather-related covariates, and determine the magnitude of process variation in target parameters. Average estimates of survival probabilities were 0.51 (Standard error [SE]=0.04) and 0.43 (SE=0.04), and average estimates of recruitment probabilities were 0.64 (SE=0.07) and 0.44 (SE=0.04). Process variation accounted for greater than 76% of the total temporal variation in both parameters at one pond and in survival probability alone at the other.

Data were collected to inform conservation and management of amphibian populations. Information will be used to understand demographics of natural populations (survival, recruitment, and population growth rate), disease, and occupancy of amphibians across a landscape
