Since the early 1990s, > 5,000 ha of historic wetlands (and adjacent prairie)
have been restored on the row-crop agricultural landscape of Winnebago County, Iowa, USA.
From 2008?2011, we surveyed 22 of these sites for probabilities of occupancy and colonization
by Boreal Chorus Frogs (BCF; Pseudacris maculata), Northern Leopard Frogs (NLF; Lithobates
pipiens), and American Toads (AT; Anaxyrus americanus). We used radio telemetry to measure
patterns of movement and habitat use by 22 NLF and 54 AT, and deployed biophysical models
in available habitats to estimate their physiological costs. BCF occupied 100% of restored
wetlands; NLF and AT occupied 59?91% and 71?89%, respectively, varying according to annual
weather conditions. BCF colonized new sites within a year; NLF and AT required 3 and 2 yr,
