COMPLEX ASSOCIATIONS OF ENVIRONMENTAL FACTORS MAY EXPLAIN BLANCHARD'S CRICKET FROG, ACRIS BLANCHARDI, DECLINES AND DRIVE POPULATION RECOVERY

Abstract

Blanchard’s Cricket Frog, Acris blanchardi, is a small hylid frog that was once among the most common amphibians in any part of its range.  Today, it remains abundant in much of the southern portion of its range, but is now disappearing elsewhere.  Our analysis of habitat characters observed across several states revealed interesting relationships of these factors with the abundance or presence of Blanchard’s Cricket Frog.  Further, we later established two ½ acre ponds based on these relationships that led to immediate colonization of the ponds by cricket frogs followed by explosive production of juveniles less than a year later.  Our findings suggest that habitat management for this species should specifically manage the shoreline grade and especially the aquatic floating vegetation to maximize population growth and sustenance.
