It's not clear whether the population declines are linked to the deformities. Many experts believe habitat loss is the biggest cause of declining frog populations.
The U.S. Fish and Wildlife Service is completing its research on amphibians at wildlife refuges around the country, and a report is due in a couple of weeks. It's expected to show continuing outbreaks of deformed frogs.
Helgen said hope for wetlands and the creatures that inhabit them rests in the younger generation -- like the children who visit the Ney Nature Center.
"If the kids grow up to be active adults who want to have good science done and really want to have species protected -- those two things -- I think they could make a difference."
