The final Chiricahua leopard frog survey for 2010 was completed in September.  The first two surveys produced no observations of adult frogs.  This is attributed to increased predation on the frogs attributed to habitat loss due to the drop in the water table from the drought in the area.  While no observations of adult frogs were made in April and June, during the first two of the three surveys for the year, there were several times outside of the surveys that tadpoles were seen.  In fact, approximately 25 tadpoles were captured for a captive breeding program at the Southwestern Research Station in Portal, Arizona.  In late July and early August after a flood event, Refuge Staff began to see juvenile frogs in many sections of the creek and during the September survey 31 juvenile frogs were seen one day and 29 the next.  All frogs are of the same age, ranging in size from 20 to 50 mm (estimated).
